Lista de personajes de Supernatural y Los Winchester

Notas

Anael, interpretada por Danneel Ackles , es descrita como una funcionaria de bajo nivel. Aparece por primera vez en el episodio "El trato del diablo" de la temporada 12, bajo la apariencia de su huésped, la Hermana Jo, trabajando como sanadora . Anael es encontrada por Lucifer , quien busca ángeles para absorber su gracia y recargar la suya. Al reconocer al arcángel renegado, Anael convence a Lucifer de que tome parte de su gracia, le permita recargarse y luego tome más. Los Winchester y Castiel finalmente localizan a Anael y Lucifer. Anael finge cooperar con ellos, alegando que Lucifer es extremadamente débil. En su habitación de motel, Anael ayuda a Lucifer a luchar contra los Winchester y Castiel. Antes de que Lucifer pueda matarlos, Arthur Ketch aparece y lanza una bomba demoníaca, lo que provoca que Lucifer agarre a Anael y se teletransporte lejos. A sugerencia de Anael, Lucifer visita el Portal Celestial, donde promete restaurar las alas de los ángeles y ayudar a crear nuevos ángeles si se inclinan ante él como su líder indiscutible. Posteriormente, Anael permanece al lado de Lucifer mientras todos los ángeles se inclinan ante él en la Sala del Trono Celestial.

Anael vuelve a aparecer en el episodio "Bring 'em Back Alive" de la temporada 12 como la mano derecha de Lucifer, cada vez más frustrada por sus payasadas. Lucifer finalmente le confiesa a Anael que le mintió sobre su capacidad para restaurar las alas de los ángeles y crear nuevos, y la ataca violentamente, pero no logra matarla. Harta de la situación, Anael le dice a Lucifer que ahora no tiene nada y que también la ha perdido. Posteriormente, Lucifer abandona el Cielo. En "Funeralia", se revela que Anael es una de las menos de una docena de ángeles vivos en toda la creación. Aparece brevemente en las temporadas 14 y 15.

Balthazar, interpretado por Sebastian Roché , es un ángel que luchó junto a Castiel durante la última guerra angelical. Aunque se le creía muerto, esto era solo una tapadera, ya que abandonó el Cielo llevándose armas consigo. Ha estado en la Tierra disfrutando de un estilo de vida hedonista. En "El tercer hombre", los Winchester descubren que tres policías corruptos fueron asesinados por el hermano menor de una de sus víctimas, quien poseía el Báculo de Moisés. Se revela que Balthazar se lo vendió al chico a cambio de su alma. Durante un conflicto con Rafael y sus secuaces, Balthazar destruye el recipiente del arcángel con la Sal de Lot. Dean atrapa a Balthazar en un anillo de Fuego Sagrado y lo obliga a entregar el alma del chico. Quieren más de él, pero Castiel lo libera porque le debe la vida. Sam usa un ritual enoquiano para invocar a Balthazar en "Cita en Samarra". Sam le pregunta si hay alguna manera de mantener un alma fuera de su cuerpo. Balthazar le informa de un ritual que implica que él profane su cuerpo, ayudando a Sam porque le resultaría útil tenerlo en deuda con él. Le dice a Sam que necesitaría la sangre de su padre (que no necesariamente proviene del "padre de tu sangre"), lo que impulsa a Sam a intentar matar a Bobby antes de que sea sometido, Dean y la Muerte recuperen el alma de Sam. En "El error francés", Balthazar transporta a Sam y Dean a un universo alternativo para evadir al sicario angelical Virgil y les da una llave que, según él, da acceso a las armas que robó del Cielo. Se revela que esto fue una estratagema de Balthazar y Castiel para permitir que este último recuperara las armas de su verdadera ubicación mientras Rafael estaba distraído. Un alias sospechoso usado por Balthazar en 1912 lleva a los hermanos a invocar a Balthazar en "My Heart Will Go On". Balthazar afirma que salvó al Titanic simplemente porque detestaba la película y la posterior canción homónima. Sin embargo, al enfrentarse al Destino, Atropos revela que sabe que Balthazar trabaja para Castiel; salvar el Titanic era para proporcionar almas adicionales que financiaran su bando en la guerra civil. Castiel se retira del plan de matar a Atropos cuando ella amenaza a los Winchester, impidiendo que Balthazar la mate. Cuando los Winchester revelan que Castiel está aliado con Crowley en "Let It Bleed", Balthazar acepta ayudar a los hermanos y actuar como agente doble. Luego transporta a Sam y Dean al lugar donde Lisa y Ben están cautivos. En "The Man Who Knew too Much", Balthazar comienza a dudar sobre traicionar a Castiel, pero finalmente continúa ayudando a los hermanos. Informa a Dean y Bobby sobre dónde tendrá lugar el ritual para abrir la puerta al Purgatorio. Castiel convoca a Balthazar y revela que está al tanto de sus acciones; entonces, Castiel mata a Balthazar.

Un ángel, interpretado por Adam J. Harrington , quien tras la caída comenzó a reunir a otros ángeles en una facción para reconquistar y gobernar el Cielo. Bartholomew es descrito como un protegido de Naomi y en "No soy un ángel", utiliza al predicador de internet Reverendo Buddy Boyle para encontrar recipientes para otros ángeles. Buscando venganza por la expulsión de los ángeles, Bartholomew envía a sus seguidores tras Castiel y, cuando este se protege de ser detectado por ángeles, segadores renegados. En "Terror sagrado" , Bartholomew ha cambiado de estrategia y ahora usa a Boyle para atacar a grupos selectos en lugar de al mundo entero, para así controlar quién se convierte en recipiente, queriendo que solo sus seguidores obtengan recipientes. Después de que algunos de los ángeles de Bartholomew son masacrados por ángeles bajo el mando del anarquista Malachi, Bartholomew se niega a reunirse con él y comienza una guerra civil angelical entre su facción y la de Malachi. En "Cautivos" , Bartholomew ha comenzado a destruir a todas las demás facciones, incluso a las pacíficas, pues las considera una amenaza para su poder, y sus hombres capturan a Castiel. Bartholomew se complace con esto, pues aparentemente ha dejado de lado su resentimiento anterior, ya que es un viejo amigo y aliado de Castiel. Bartholomew invita a Castiel a unirse a él, tras haber convertido a todos sus seguidores humanos en recipientes y utilizando sus recursos para rastrear a Metatron cuando aparezca en la Tierra. Bartholomew cree que con Castiel de su lado podrá unir a los ángeles bajo su mando y recuperar el Cielo, pero Castiel se niega a ayudar cuando tortura a un ángel inocente. Cuando Castiel se niega a matar al ángel, Bartholomew lo ataca, pero Castiel lo domina. Aunque Castiel tiene a Bartholomew a su merced, se niega a matarlo, pues no quiere más muertes de ángeles, y lo deja ir. Bartholomew se niega a detenerse, desenvaina una segunda espada angelical y ataca a Castiel por la espalda. Sin otra opción, Castiel mata a Bartolomé en defensa propia con su propia espada. Posteriormente, varios de sus seguidores deciden seguir a Castiel, al ver en su negativa a matarlo y su deseo de que no haya más derramamiento de sangre un camino diferente.

Billie, interpretada por Lisa Berry , fue presentada en la temporada 11. Es una segadora que aparece por primera vez en "Forma y Vacío". Conoce a Sam dentro de un hospital cuyos habitantes están muriendo debido a la infección de la Oscuridad, y ella actúa como su segadora. A pesar de que Dean mató a la Muerte en la temporada anterior, aún hay almas que deben ser recolectadas. Billie le dice a Sam que está cansada de verlos a él y a Dean morir y regresar una y otra vez, prometiéndoles que la próxima vez que mueran, los llevará al Vacío, de donde ninguna alma puede escapar. Billie presiente que Sam es "impuro en el sentido bíblico" y cree que pronto lo cosechará. Aunque Sam está a punto de sucumbir a su infección Rabia, recuerda el comentario de Billie sobre ser "impuro en el sentido bíblico" y descubre una cura a través del fuego sagrado después de buscar purificaciones bíblicas.

En "El diablo en los detalles", Billie regresa custodiando una puerta al Infierno para Crowley , afirmando que le resulta útil que el Rey del Infierno le deba un favor en tiempos tan difíciles. Cuando llega Dean, Billie lo deja entrar antes de revelarle su identidad. Billie deja claro que, si bien no desea matar a los Winchester, simplemente pretende asegurarse de que permanezcan muertos cuando mueran. Billie le entrega a Dean un cazador de brujas que ha encontrado para Crowley y, más tarde, deja pasar a Castiel cuando este es teletransportado inesperadamente a la habitación.

En "Red Meat", un desesperado Dean decide contactar a Billie para hacer un trato tras la aparente muerte de Sam. Dean se suicida con una sobredosis de pastillas recetadas. Mientras un médico intenta desesperadamente reanimarlo, Billie llega y congela el tiempo para "saborear el momento". Aunque Dean intenta negociar con Billie, ella se niega, decidida a llevarlo al Vacío. Si bien Dean insiste en que Sam es el único que puede vencer a la Oscuridad, Billie discrepa y le dice que incluso si Sam pudiera derrotarla, ella no lo traería de vuelta y que "la respuesta siempre será no". Billie le revela entonces al conmocionado Dean que Sam no está muerto, como le habrían dicho si Sam hubiera muerto. Billie descongela el tiempo y se prepara para llevar a Dean al Vacío, pero el médico logra reanimarlo con una inyección de adrenalina en el corazón. Decepcionada, Billie se marcha sola.

En " Alfa y Omega ", Billie ve a los Winchester recolectando fantasmas en el Sanatorio de Waverly Hills y los sigue hasta el búnker de los Hombres de Letras, donde presiente que Dios está muriendo. Después de que los Winchester, Castiel, Crowley y Dios le explican su plan, Billie acepta ayudar, diciendo: "Un pequeño consejo: si quieren almas, llamen a un segador". Billie logra extraer cientos de miles de almas del Velo y colocarlas en el cristal para la Bomba de Almas de los Winchester, dándoles así los medios para potencialmente matar a la Oscuridad. Billie se marcha tras despedirse de Crowley y le dice a Dean que, aunque la volverán a ver, espera que no sea hoy.

En el episodio de la temporada 12, "Celebrando la vida de Asa Fox", Billie regresa para cosechar las almas de aquellos asesinados por el demonio Jael, advirtiendo a Dean, quien está atrapado fuera de la casa, sobre la amenaza. Dean le ruega a Billie que lo ayude a entrar, prometiéndole que le deberá un favor a cambio. Billie acepta y arroja a Dean directamente a través de la puerta de la casa. Después de que Jael es exorcizado, Billie reaparece para reclamar lo que Dean le debe: la recién resucitada Mary Winchester. Billie reconoce que Mary está luchando por aceptar su regreso y le ofrece paz. Mary confirma que Billie no puede matarla ella misma debido a las reglas y finalmente elige quedarse en lugar de abandonar a sus hijos nuevamente. Billie deja a Mary en paz y les dice a los Winchester que si alguna vez quieren paz, solo tienen que llamarla.

En "First Blood", Billie reaparece a medianoche después de que los Winchester escapan del Sitio 94. Sam y Dean revelan que estaban perdiendo la cordura durante su cautiverio, así que invocaron a Billie e hicieron un trato con ella: a cambio de que Billie los matara temporalmente y luego los reviviera para que pudieran escapar, uno de los Winchester moriría definitivamente a medianoche. Billie hizo que los Winchester sellaran el trato con sangre y les advirtió que romperlo podría tener consecuencias cósmicas. Como Mary es una Winchester, decide sacrificarse en lugar de obligar a uno de sus hijos a morir, y Billie impide que Sam y Dean interfieran. Antes de que Mary pueda suicidarse, Castiel mata a Billie por la espalda con una espada angelical, para sorpresa de los Winchester. Castiel expresa su creencia de que el mundo no puede permitirse perder a ningún miembro de la familia y que actuó en su propio beneficio al matar a Billie para romper el trato. Como resultado, Dean se enfada con Castiel durante el episodio "Lily Sunder Has Some Regrets" y finalmente admite que le preocupa la advertencia de Billie sobre las consecuencias cósmicas de romper el trato.

En el episodio "Tanatología avanzada" de la temporada 13 , Billie regresa inesperadamente después de que Dean se suicida brevemente para averiguar la ubicación de los restos de un grupo de fantasmas. Cuando Sam no puede revivir a Dean, Billie aparece y detiene el tiempo. Billie le revela a Dean que una de las reglas del Universo es que cuando una encarnación de la Muerte muere, el siguiente segador que muera tomará su lugar. Como resultado, Billie ha resucitado como la nueva Muerte con un nuevo atuendo, un anillo y una guadaña como la antigua Muerte. Billie transporta a Dean a su oficina en el Velo y le pregunta sobre la grieta que se abrió brevemente a otro universo. Dean acepta contarle a Billie lo que quiere saber si ella libera a los fantasmas atrapados, un trato que Billie acepta y envía a la segadora Jessica para que lo complete. Dean explica las circunstancias detrás de la grieta y Billie le muestra su biblioteca, donde se exhiben todos los posibles métodos de muerte para una persona. Con una nueva perspectiva sobre la vida y la muerte, Billie pronto se da cuenta de cuánto ha cambiado Dean desde su pacto desinteresado y de que, en realidad, desea morir. En lugar de llevarlo al Vacío, una divertida Billie le dice a Dean que siga viviendo y lo resucita personalmente. Tras su regreso a la vida, Dean le cuenta a Sam su encuentro con Billie, quien era la Muerte.

En "Funeralia", la bruja Rowena comienza a matar gente y a los segadores enviados para recoger sus almas con el fin de atraer la atención de Billie y obligarla a resucitar a Crowley. En respuesta, Billie le pide a la segadora Jessica, a quien ha estado siguiendo a los Winchester, que les avise de la amenaza. Sin embargo, Jessica no puede intervenir directamente debido a las reglas de Billie y solo puede ofrecer información. Jessica también transmite un mensaje de Billie: en todas las versiones de la muerte final de Rowena, ella muere a manos de Sam. Después de que Rowena comienza a torturar a Sam, Billie aparece en persona y se niega a ceder al chantaje de Rowena. Billie resiste fácilmente el ataque mágico de Rowena y le ofrece consuelo, reconociendo que Rowena ha cambiado, pero continúa negándose a traer de vuelta a Crowley. Antes de irse, Billie le promete a Dean "verte pronto" y se revela que el ataque mágico de Rowena contra Billie ha agotado sus poderes mejorados, posiblemente hasta el punto de que nunca se recuperarán.

En el episodio "Nihilismo" de la temporada 14, Sam intenta que la parca Violeta lo transporte a él, a Castiel, a Jack y a Michael a un lugar seguro. Violeta se niega debido a las reglas de Billie, antes de que sean teletransportados inesperadamente al Búnker. Después de que Michael queda atrapado en la mente de Dean, recibe la visita de Billie, quien se da cuenta de que los salvó a pesar de haber roto las reglas. Billie admite que "se arriesgó" al ayudarlos y le recuerda a Dean la vez que visitó su sala de lectura, donde se mostraron las muchas formas en que podría morir. Billie revela que en todas las versiones de su destino, excepto en una, Michael se libera y usa el cuerpo de Dean para destruir el mundo. Reprende a Dean por sus viajes interdimensionales. Billie le entrega a Dean el libro que contiene el único destino en el que Michael pierde, dejando a Dean en estado de shock por lo que revela. Billie le dice a Dean que debe decidir qué hacer con la información y desaparece. En "Mercancías dañadas", Dean le cuenta a Sam que Billie le reveló que la única forma de detener a Michael es que Dean construya una Caja Ma'lak y quede atrapado junto a Michael para siempre. Para ello, Billie le ha proporcionado a Dean las instrucciones para construir la caja.

En "Moriah", después de que Dios mata a Jack y comienza el fin del mundo, Billie aparece en el Vacío con Jack y la Sombra.

En el episodio "La trampa" de la temporada 15, Billie visita a Jack en el Vacío, quien aún está despierto, después de que los Winchester deciden no encerrar a Dios tras enterarse de las consecuencias para el mundo. Billie le dice al joven Nephilim que "es hora".

En "Los Jugadores", se revela que Billie resucitó a Jack y lo guía para que ataque a los Grigori, ángeles caídos que se alimentan de las almas de personas inocentes. Jack explica más tarde que Billie lo mantuvo oculto en el Vacío hasta que Dios abandonó la Tierra, lo que permitió su resurrección. Billie le ha proporcionado a Jack un plan que le permitirá volverse lo suficientemente fuerte como para matar al mismísimo Dios.

En "Galaxy Brain", se revela que Billie no pudo restaurar el alma de Jack cuando lo resucitó. Ignora las oraciones de Jack y, en su lugar, asigna a un segador llamado Merle para que lo vigile y controle. Después de que Jack abre una grieta al Lugar Malo en contra de sus instrucciones explícitas, Billie mata a Merle y explica que Dios ha estado destruyendo todos los universos alternativos y afirma que incluso Dios tiene un libro en su biblioteca que detalla su destino final. Billie afirma que Jack, Sam y Dean están en el libro, al que Dios no puede acceder sin su permiso, pero se niega a dar más explicaciones, salvo que el destino de Sam y Dean es ser los mensajeros de la destrucción de Dios.

En "Destiny's Child", Billie revela que Dios está a punto de terminar de destruir otros universos y pronto volverá a centrar su atención en su mundo. Billie le asigna a Jack otra misión, esta vez de naturaleza más espiritual. Billie les ordena a los Winchester, a Jack y a Castiel que encuentren el Occultum, aunque se niega a explicar qué hará y desconoce su paradero. Cuando Castiel entra más tarde al Vacío para hablar con Ruby , la última dueña del Occultum, se revela que Billie y la Sombra trabajan juntas y, como resultado, Billie puede resucitar a Jack. Billie le ha prometido a la entidad que, una vez que todo termine, la volverá a dormir, algo que anhela desesperadamente. Sin embargo, mientras tortura a Castiel, la Sombra comenta que Billie nunca mencionó necesitarlo para su plan. Finalmente, Jack cumple su misión, lo que provoca que el Occultum restaure el alma perdida de Jack.

En "Gimme Shelter", Jack revela que el plan de Billie para matar tanto a Chuck como a Amara, que consiste en convertir a Jack en una bomba que provocará la desaparición de Dios y la Oscuridad, también lo matará a él.

En «Arrástrame (de ti)», Billie visita a Dean y le revela que Chuck ha terminado de destruir universos alternativos y que pronto regresará. Le ha encomendado a Jack su última misión para que la prepare y, según el libro, su papel ha concluido hasta el final. Billie insiste en que Dean le cuente la verdad a Sam, y él le asegura que está listo para llevar a cabo el plan, aunque no le guste.

En "Unidad", Dean y Jack siguen las instrucciones de Billie y localizan a Adam , quien revela que Billie lo ha mantenido con vida durante 300.000 años mientras él tramaba un plan para matar a Dios; Billie simplemente ha estado ayudando a Adam a ejecutar su plan. Al mismo tiempo, Sam localiza la Llave de la Muerte y entra en la biblioteca de Billie buscándola, solo para encontrar a la Sombra, quien también la busca. Para sorpresa de Sam, la Sombra revela que el verdadero plan de Billie es tomar el poder como el nuevo Dios una vez que Dios y Amara mueran, y se asegurará de que cualquiera que haya resucitado muera y que todos los de universos alternativos regresen a su propio mundo, una sentencia de muerte ya que los otros mundos han desaparecido. Chuck admite ante Amara que todo esto es parte de su plan para que los Winchester se maten entre sí, después de haber provocado a Billie. Sin embargo, Sam convence a Dean de que no siga adelante con el plan y un Dios enfurecido se marcha mientras Jack comienza a detonar.

En "Desesperación", mientras los Winchester y Castiel intentan encontrar la manera de ayudar a Jack, Billie aparece en el búnker, furiosa por su fracaso al no haber podido matar a Chuck y Amara. Aunque no puede evitar la detonación, Billie logra teletransportar a Jack al Vacío, donde detona en su lugar, explicando que, con Dios y Amara desaparecidos, solo la Sombra puede soportar tal impacto. Billie admite entonces que es posible que Jack haya sobrevivido, señalando que solo dijo que sería fatal, no que lo mataría. Castiel se da cuenta de que la muerte de Chuck y Amara habría desencadenado una reacción en cadena. El grupo confronta a Billie por sus mentiras y por cómo los ha manipulado, a lo que ella admite y exige que le devuelvan el libro de la muerte de Chuck a cambio de traer de vuelta a Jack del Vacío. Sam entrega el libro a regañadientes. Billie trae de vuelta a Jack, pero intenta llevárselo consigo. Agarrando la Guadaña de la Muerte, Dean hiere a Billie en el hombro, obligándola a huir sin Jack, el libro ni la guadaña. Tras la muerte de sus amigos, Dean decide dar caza a Billie, creyendo que ella es la responsable. Después de un breve enfrentamiento, Billie revela que Chuck fue el verdadero culpable. Herida de muerte por el ataque previo de Dean, Billie persigue a Castiel y a Dean para matar a Dean antes de morir. Al darse cuenta de que solo la Sombra, que guarda rencor a Billie, puede detenerla, Castiel experimenta un momento de verdadera felicidad al expresar su amor por Dean, cumpliendo así su pacto con la Sombra. La Sombra abre un portal al Vacío y envía dos tentáculos de oscuridad, uno de los cuales absorbe a Billie, antes de que ambos sean arrastrados al Vacío.

Dumah es un ángel, interpretado por Erica Cerra , que es uno de los pocos ángeles que quedan con vida al final de la temporada 13 y parece ostentar una posición de poder entre ellos.

Dumah aparece por primera vez en "La guerra de los mundos" como el contacto de Castiel en el Cielo, con quien se reúne para hablar sobre la desaparición de Jack. Dumah le asegura a Castiel que Jack no está bajo la custodia de los ángeles y revela que lo buscan porque lo ven como su única oportunidad para crear nuevos ángeles. Dumah le dice a Castiel que los ángeles están en peligro de extinción y que están dispuestos a hacer cualquier cosa para sobrevivir , incluso esclavizar a Jack. Dumah trae a otros dos ángeles para emboscar a Castiel, quien se defiende. La escaramuza se ve interrumpida por la aparición sorpresiva de Lucifer, quien ahuyenta a Dumah y a los otros dos ángeles.

En «El pacto del diablo», Lucifer y Anael se reúnen con Dumah y otros ángeles fuera del Portal Celestial. Lucifer promete que si los ángeles se inclinan ante él como su líder, podrá restaurar sus alas y crear nuevos ángeles, afirmando saber cómo hacerlo, pues presenció la creación de ángeles por parte de Dios. Posteriormente, Dumah y los ángeles se inclinan ante Lucifer en la Sala del Trono Celestial. Dumah aparece más tarde en «Tráiganlos de vuelta con vida» y Lucifer le ordena que envíe ángeles a buscar a su hijo. Tras una breve vacilación, ella acepta.

En "Funeralia", Castiel regresa a un Cielo que experimenta fluctuaciones de poder. Allí se encuentra con Dumah y algunos otros ángeles, a quienes solicita ayuda, diciéndoles que Gabriel sigue vivo, que un Miguel alternativo está a punto de invadir, que Jack está atrapado y que Lucifer es peligroso. Mientras el poder fluctúa a su alrededor, Dumah le dice a Castiel que tal vez puedan ayudarse mutuamente, le ordena que espere en la sala del trono y desaparece. Al regresar, Dumah le dice a Castiel que si logra encontrar a Gabriel y traerlo de vuelta al Cielo, los ángeles podrán ayudarlo con todo lo demás, como encontrar a Miguel y defender la Tierra. Cuando Castiel le dice que necesita su ayuda para encontrarlos, Dumah admite que eso es un problema. Castiel pregunta por qué Dumah no puede simplemente enviar ángeles a buscar a Gabriel antes de que aparezca Naomi, y ella le responde que ni ella ni los demás ángeles pueden hacerlo. Naomi explica entonces que quedan menos de una docena de ángeles vivos, incluyendo a Castiel, Naomi y Dumah. La escasez de ángeles está provocando fluctuaciones de energía en el Cielo, y si la situación no cambia pronto, los ángeles se agotarán y el Cielo se derrumbará. Por consiguiente, Naomi y los ángeles que aún quedan en el Cielo no pueden abandonarlo sin arriesgarse a que este se derrumbe.

En "Bizancio", Castiel descubre que el Cielo ha sido invadido por la Entidad Cósmica en busca del alma de Jack. Castiel encuentra a Dumah inconsciente, quien despierta y se une a él en su misión de encontrar y resucitar a Jack. Tras encontrar a Jack, se revela que Dumah está poseída por la Entidad, quien usa su forma para atacar a Castiel y negociar con él. Cuando la Entidad abandona el Cielo, deja el cuerpo de Dumah, sin ningún recuerdo aparente de su posesión.

En «Ausencia», Castiel llama a Naomi tras la muerte de Mary Winchester. Dumah solo le dice que Naomi está «indispuesta», pero confirma que Mary Winchester ha muerto y descansa en paz en el Cielo. Para demostrarlo, Dumah permite que Castiel entre al Cielo, donde ve a Mary en paz en un Cielo compartido con John Winchester.

En "Jack in the Box", Castiel regresa al Cielo para pedirle ayuda a Naomi para encontrar a Jack. Dumah revela que ha derrocado a Naomi, señalando que la Entidad invadió el Cielo bajo su vigilancia y casi mató a todos los ángeles. Aunque Dumah promete ayudar, localiza a Jack y comienza a manipularlo para sus propios fines, creando un reinado de terror donde los humanos son sometidos a golpes, el Cielo es despojado de toda misericordia y Jack actúa para consolidar el poder de Dumah. Dumah defiende sus acciones como necesarias para salvar el Cielo, los ángeles y el mundo, y declara su intención de guiar a Jack. Cuando Castiel se dispone a llevarse a Jack y marcharse, Dumah lo detiene y amenaza con usar su nuevo poder sobre el Cielo para acabar con la paz que John y Mary compartían en el Cielo. Enfurecido, Castiel desenvaina su espada angelical y mata a Dumah antes de que pueda reaccionar, dejando su cuerpo en el suelo del Cielo mientras Castiel se dirige tras Jack. En "Moriah", Jack reconoce que Dumah lo había estado utilizando cuando habla con Castiel.

Gabriel (también conocido como el Embaucador o Loki) es un arcángel interpretado por Richard Speight, Jr. Cansado de ver a sus hermanos pelear entre sí en el Cielo, huyó a la Tierra miles de años antes de la serie , asumiendo el papel de un embaucador pagano . Para su primera aparición en el episodio de la temporada 2 " Tall Tales ", los guionistas decidieron no darle su propio toque a la tradición del embaucador, como suele hacerse con otros villanos, manteniendo el "sentido del humor mortal" y la decisión de ir tras los "poderosos para bajarles los humos", ^{[ 4 ]} con Gabriel haciendo que violentas leyendas urbanas cobren vida en un campus universitario y castigando a los residentes. Sam y Dean Winchester investigan y finalmente descubren su identidad, aunque el Embaucador los está esperando y ofrece una resolución pacífica siempre y cuando lo dejen ir a aterrorizar otra ciudad. Sam y Dean se niegan y lo atacan con la ayuda del cazador Bobby Singer, y el Embaucador finge su propia muerte.

El Embaucador reaparece en el episodio " Mystery Spot " de la tercera temporada, atrapando a Sam en un bucle temporal donde Dean muere de muchas maneras diferentes. Tras más de cien bucles, Sam amenaza al Embaucador con una estaca ensangrentada, tras lo cual este accede a romper el bucle. Pero cuando Sam considera matarlo de todos modos, el Embaucador los envía al día siguiente, donde Dean muere una vez más, pero no puede resucitar sin el bucle temporal. Meses después, llama a Sam para dejarle claro un punto: que los dos hermanos se sacrifiquen continuamente el uno por el otro no trae nada bueno, y que cuando alguien muere, los supervivientes simplemente tienen que aceptarlo. Sin embargo, el Embaucador le da a Sam lo que quiere, lamentando que toda la situación se había vuelto aburrida para él hacía meses.

En el episodio de la quinta temporada " Changing Channels ", atrae a los Winchester con un caso que deja claro su implicación. Atrapa a Sam y Dean en una interminable sucesión de programas de televisión donde deben representar sus papeles para sobrevivir, ignorando sus intentos de que se una a ellos. Gabriel explica que esta es su manera de conseguir que acepten sus roles como recipientes de Lucifer y Miguel, respectivamente. En uno de los escenarios, destierra a Castiel y se enfurece ante una respuesta sobre los Arcángeles. Más tarde, es apuñalado con una estaca, un acto que mata a otros espíritus embaucadores; sin embargo, continúa incluyéndolos en los programas. Dean y Sam lo atrapan en un círculo ardiente de aceite sagrado, sospechando que es un ángel por haber sobrevivido a la estaca, por cómo interactuó con Castiel y por su ira ante los insultos de los Arcángeles. Entonces revela que es Gabriel, lo cual no les sorprende. Explica que abandonó el Cielo debido a un conflicto con su familia. Incluso expresa su deseo de que los Winchester acepten convertirse en recipientes, ya que sus vidas reflejan las de los ángeles. Dean lo obliga a traer de vuelta a Castiel y libera a Gabriel de su trampa, acusándolo de rendirse por miedo a enfrentarse a su propia familia.

En "El Martillo de los Dioses", Gabriel asiste a la cumbre de dioses paganos disfrazado de Loki; sin embargo, su intención es rescatar a los hermanos, ya que su plan para atraer a Lucifer fracasaría fácilmente y este los masacraría a todos. Para evitar que Kali , un antiguo amor, sufra un destino sangriento, intenta sacarlos de allí; pero les dice que rescatar a los rehenes paganos sería demasiado difícil. Sin embargo, más tarde se ve obligado a acceder; el intento de rescate resulta en la recaptura de los hermanos. Kali (quien impide que los hermanos se vayan, pues su sangre derramada los ata a ella) revela que ella, junto con los demás dioses, conocía su identidad desde hace tiempo. Kali toma su espada y lo apuñala, aparentemente matándolo, pero Gabriel se aparece ante Dean y revela que la espada era falsa, sugiriéndole que seduzca a Kali para poder escapar. Lucifer aparece en el hotel y masacra a la mayoría de los dioses. Gabriel se ve obligado a intervenir, permitiendo que Kali y los hermanos se marchen. Gabriel confronta a su hermano sobre lealtades y su pasado, pero finalmente fracasa y muere a manos de su propia espada. Más tarde, revela, a través de una película pornográfica modificada, que Lucifer puede ser reencarcelado en su prisión anterior, con los cuatro anillos de los Jinetes del Apocalipsis.

Gabriel regresa en el episodio "Meta Ficción" de la novena temporada, donde le revela a Castiel que ha estado en el Cielo desde que "murió". Sin embargo, cuando el Cielo expulsó a todos los ángeles, Gabriel se vio obligado a huir de Metatrón. Le cuenta a Castiel que Metatrón estaba usando el Cuerno de Gabriel para atrapar y matar a los ángeles y que necesita la ayuda de Castiel para luchar. Mientras corren, se detienen en una gasolinera donde se dan cuenta de que algunos de los súbditos leales de Metatrón los están siguiendo. Gabriel se ofrece a luchar contra ellos porque aún conserva algunos de sus poderes de Arcángel, pero Castiel se da cuenta de que toda la situación es una ilusión. Castiel le pregunta a Gabriel si realmente sigue vivo, pero Gabriel solo levanta las cejas antes de desaparecer. Metatrón comenta más tarde que Gabriel hizo bien su papel.

En "We Happy Few", Dios confirma la muerte de Gabriel cuando hablan de cómo los cuatro arcángeles fueron necesarios para ayudar a Dios a derrotar a la Oscuridad la primera vez. Dios les dice a los Winchester que, si bien Lucifer lucha con ellos, Miguel no está en condiciones de combatir y Rafael y Gabriel han muerto. Cuando Dean le recuerda a Dios que ya resucitó a Castiel, Dios le dice que no puede resucitar a los arcángeles tan fácilmente, ya que son seres de la creación primordial. Por lo tanto, resucitar a Gabriel y Rafael para que ayuden a combatir la Oscuridad llevará demasiado tiempo.

En el episodio "El pacto del diablo" de la temporada 13, el príncipe del infierno Asmodeo le revela a Arthur Ketch que se ha apoderado de la Espada del Arcángel, la única arma conocida capaz de matar a un arcángel. Cuando Arthur le recuerda a Asmodeo que la tradición dice que solo un arcángel puede empuñar la espada, Asmodeo revela que tiene a Gabriel, quien de alguna manera sigue vivo, prisionero. Gabriel se encuentra ahora malherido y ensangrentado, con la boca cosida.

En «La Cosa», Arthur descubre que Asmodeo se inyecta la gracia de Gabriel para aumentar su poder. Tras una brutal paliza propinada por Asmodeo, Arthur rescata a Gabriel y roba la espada del arcángel y la reserva de la gracia de Gabriel que Asmodeo guardaba. Arthur lleva al traumatizado Gabriel ante los Winchester, quienes se sorprenden al ver al arcángel, a quien creían muerto, y al enterarse de su cautiverio. Usando la gracia extraída de Gabriel, los Winchester logran completar un ritual para abrir una puerta a una realidad alternativa que Dean atraviesa, dejando atrás a Sam y Gabriel.

En "Bring 'em Back Alive", Sam y Castiel intentan tratar al traumatizado Gabriel, quien se encoge ante cualquier intento de ayudarlo y parece incapaz de hablar, incluso después de que le quitan los puntos que le sujetan la boca. Finalmente, Gabriel escribe su historia en la pared en enoquiano, revelando que fingió su muerte durante el Apocalipsis engañando a Lucifer para que apuñalara a un duplicado de sí mismo. Libre de responsabilidades, Gabriel regresó a un estilo de vida hedonista en Montecarlo hasta que fue capturado y vendido a Asmodeo. Tras una súplica de Sam, Gabriel comienza a responder, pero se repliega de nuevo al enterarse de que Asmodeo sabe dónde está. Cuando Asmodeo invade el búnker, Gabriel es recapturado, pero sale de su estado traumatizado cuando Asmodeo comienza a torturar a Sam y Castiel. Tras curarse, Gabriel mata rápidamente a Asmodeo. Se le informa de los acontecimientos que ocurrieron en su ausencia, pero se niega a ayudar más y abandona el búnker. Tras la partida de Gabriel y el uso de la última gota de su gracia almacenada para intentar curarlo, los Winchester se quedan sin forma de reabrir la puerta al Mundo Apocalipsis. Además, se quedan sin un poderoso aliado que podría haberles ayudado a luchar contra Michael.

Durante el funeral, Castiel visitó el Cielo y, para su sorpresa, descubrió que los demás ángeles sabían que Gabriel seguía con vida. Naomi le encargó a Castiel que recuperara a Gabriel para que el Cielo pudiera funcionar correctamente debido al bajo número de ángeles.

En "Asuntos Pendientes", Gabriel busca vengarse de los dioses paganos Loki , Fenrir , Narfi y Sleipnir . Se revela que milenios antes, Gabriel rescató a Loki e hizo un trato con él en el que Gabriel adoptó la forma y personalidad de Loki como El Embaucador para entrar en el programa de protección de testigos. Gabriel había buscado la ayuda de Loki después de fingir su muerte, solo para que Loki lo traicionara y lo vendiera a Asmodeo. Con poca gracia y herido, Gabriel se arma con espadas de madera especialmente forjadas y busca la ayuda de los Winchester después de resultar herido y sentir que lo seguían. A cambio de que Gabriel los ayude, los Winchester acceden a ayudarlo a vengarse. Con la ayuda de los Winchester, Gabriel mata a Fenrir, Narfi y Sleipnir antes de enfrentarse a Loki (también interpretado por Speight), quien culpa a Gabriel del asesinato de su padre Odín a manos de Lucifer y busca venganza. Gabriel mata a Loki y cumple su promesa de regresar al búnker con los Winchester, uniéndose a su misión para detener a Michael.

En "Vence al Diablo", Gabriel renuncia a parte de su gracia de arcángel para completar el hechizo que abre la grieta al Mundo del Apocalipsis, pero el hechizo falla. Gabriel y Rowena discuten sobre quién tiene la culpa del fallo del hechizo y Rowena coquetea con Gabriel, lo que los lleva a tener relaciones sexuales, para horror de los Winchester. Luego, él ayuda a los Winchester en su plan para capturar a Lucifer y usar su gracia para completar el hechizo. El plan tiene éxito y Gabriel viaja con los Winchester y Castiel al Mundo del Apocalipsis. Mientras viajan para encontrar a Mary y Jack, Castiel le informa a Gabriel sobre la precaria situación en el Cielo, pero Gabriel se muestra reacio a intervenir. Sam muere durante una batalla con un nido de vampiros. El grupo encuentra entonces el campamento humano donde están Mary y Jack, y Gabriel y Castiel trabajan juntos para romper la protección contra los ángeles para que puedan entrar. Tras informar a Mary y Jack de la muerte de Sam, Jack pregunta por qué Gabriel o Castiel no lo revivieron, pero Gabriel le responde que no son lo suficientemente fuertes. Acto seguido, Lucifer entra en el campamento con Sam resucitado.

En "Éxodo", Gabriel interactúa con su sobrino y su hermano antes de discrepar airadamente con la descripción que Lucifer hace de su historia y la de su familia, diciéndoles a Lucifer y a Jack que Lucifer solo se hace la víctima para justificar sus malas acciones. Esa noche, mientras Gabriel vigila a Lucifer, discuten y Gabriel compara a Lucifer con una célula cancerosa, diciendo que Dios tenía razón al arrojarlo a la jaula, lo que provoca que Lucifer se emocione y derrame lágrimas. Más tarde, ayuda a los Winchester y a sus aliados a evacuar el Mundo Apocalipsis. Entonces aparece la versión alternativa de Miguel, lo que sorprende a Gabriel. Observa cómo Lucifer es arrojado a un lado y Miguel se vuelve hacia él, mientras Gabriel les dice a los Winchester que no va a huir y decide enfrentarse a Miguel. Luego luchan, pero Miguel lo domina y mata a Gabriel con una espada de arcángel, para horror de los Winchester. Los Winchester usan esto como distracción y se retiran a su mundo. Le informan a Castiel de la muerte de Gabriel, lo cual lo entristece, pero encuentra consuelo al oír que murió con nobleza al ayudarlos a escapar.

Gadreel es un ángel interpretado por Tahmoh Penikett y Jared Padalecki . Gadreel fue asignado para custodiar el Jardín del Edén , pero cayó en desgracia cuando Lucifer entró, lo que Dios y los ángeles consideraron su culpa. Gadreel fue encerrado en la mazmorra más profunda del Cielo y torturado por su fracaso, pero fue liberado cuando el hechizo de Metatrón hizo que todos los ángeles cayeran a la Tierra. Deseando redimirse de su pasado, Gadreel responde a las oraciones de Dean pidiendo ayuda, asumiendo la identidad de un ángel llamado Ezequiel, quien murió en la Caída. Cuando los poderes de Gadreel no pueden curar a Sam, propone una solución: si posee a Sam, podría curarlo desde adentro mientras se recupera de sus propias heridas de la caída. Dean finalmente acepta y Gadreel invade la mente de Sam, asumiendo la forma de Dean para manipularlo y lograr que consienta la posesión angelical. Gadreel le dice a Dean que dejará que Sam mantenga el control de su cuerpo mientras él trabaja en segundo plano, pero que es mejor que Sam no sepa que está allí. Si Sam no permite que Gadreel permanezca en su cuerpo, podría expulsarlo y morir. En los siguientes episodios, Gadreel toma el control del cuerpo de Sam ocasionalmente para matar enemigos cuando lo superan, resucitar aliados caídos de Sam y Dean, y curar las heridas que Sam sufre en las cacerías. Regularmente borra la memoria de Sam de estos momentos para evitar que sospeche. Gadreel desconfía de la presencia de Castiel, pues teme que los ángeles que lo buscan lo encuentren y lo obliguen a abandonar el cuerpo de Sam, condenándolo así a la muerte.

Cuando Castiel aparece en un caso en "Holy Terror", Gadreel obliga una vez más a Dean a enviarlo lejos. En el mismo episodio, se cruza con Metatron, quien revela su verdadera identidad y pasado y le ofrece la oportunidad de "redimirse" convirtiéndose en su segundo al mando y ayudándolo a crear un Cielo mejor. Tras descubrir que Dean ha aprendido de Castiel que no es Ezekiel y se ha vuelto contra él, ahora intentando contarle la verdad a Sam y lograr que lo expulse, Gadreel asesina a Kevin y roba las tablillas por orden de Metatron en una muestra de lealtad a este último. En el siguiente episodio, "Road Trip", Metatron envía a Gadreel a matar a su antiguo guardia y torturador para complacer a su nuevo seguidor; sin embargo, cuando descubre que Gadreel no mató a Dean, Gadreel es castigado y obligado a matar de nuevo, esta vez a su amigo Abner. Luego es capturado por Dean, Castiel y Crowley, quienes descubren su verdadera identidad cuando Crowley le clava púas en el cerebro para devolverlo a su estado de trance, a su "configuración de fábrica". Un Castiel enfurecido le revela a Dean la causa de la infamia de Gadreel. Gadreel vuelve a la normalidad y les dice que no abandonará el cuerpo de Sam, ni ellos podrán alcanzarlo, a quien ha colocado en un mundo de fantasía sin que sepa lo que realmente está sucediendo. Crowley le revela la verdad a Sam poseyéndolo para comunicarse con él. Gadreel y Sam luchan brevemente antes de que Sam finalmente lo expulse. Gadreel continúa trabajando para Metatron, reclutando ángeles para su bando en "Meta Ficción" y matando a los que se niegan. Gadreel es capturado e interrogado por Sam y Dean, pero se niega a proporcionar información y, en cambio, intenta presionar a Dean para que lo mate, lo cual fracasa, ya que Dean sabe que necesitan a Gadreel. Gadreel se salva cuando Metatrón consigue que lo intercambien por Castiel, a quien ha capturado.

En "El Rey de los Condenados", Gadreel se reúne con Castiel, quien intenta persuadirlo de que Metatrón lo está utilizando y que debería trabajar en su contra como espía. Gadreel se niega, pues se niega a traicionar una causa a la que se ha dedicado; Castiel se muestra comprensivo y deja la oferta abierta. En el siguiente episodio, Gadreel descubre que Metatrón está haciendo que sus propios ángeles —ángeles que él mismo había reclutado— se suiciden e incriminen a Castiel, lo que provoca que pierda su apoyo, lo cual resulta ser el incentivo que necesitaba para traicionar la causa. Gadreel ofrece su ayuda a Castiel y a los Winchester; aunque Dean lo ataca. Gadreel es salvado por Sam y Castiel, quienes aceptan su ayuda. En el final, "¿Crees en los milagros?", Gadreel y Castiel planean infiltrarse en el Cielo usando un Portal mientras las Puertas están selladas y romper la conexión de Metatrón con la tablilla angelical, para que Metatrón vuelva a tener los poderes y debilidades de un ángel normal y Dean pueda matarlo con la Primera Espada. Sin embargo, los ángeles de Metatrón ya conocen su plan y los engañan para que entren en las mazmorras del Cielo, donde los encarcelan. Debido a la mala reputación de Gadreel, no logran convencerlos de que los ayuden contra Metatrón. Con la esperanza de ser recordado como un ángel que salvó el Cielo en lugar de aquel que permitió la entrada de Lucifer al Jardín, Gadreel se sacrifica usando el símbolo de los terroristas suicidas para destruirse a sí mismo y las mazmorras, liberando así a Castiel y convenciendo a Hannah, el ángel de Metatrón, de sus buenas intenciones.

Hannah, interpretada por Erica Carroll y Lee Majdoub en sus cuerpos femenino y masculino, respectivamente, es uno de los ángeles caídos del Cielo. Posee a una mujer casada llamada Caroline Johnson como su cuerpo terrenal. En el episodio "Meta Ficción", Hannah y otros ángeles son atraídos por el Sello del Cuerno de Gabriel, encantado por Gadreel. Hannah intenta matar a Castiel, quien también es atraído por el sello , pero fracasa y suplica por su vida. Junto con Castiel, llegan al sello y se encuentran con Gadreel, quien les ofrece a ellos y a otros ángeles la oportunidad de unirse a Metatrón. Cuando Hannah y sus amigos se niegan, Gadreel procede a matar a casi todos los ángeles de la zona, pero perdona a Hannah, quien es curada por Castiel; más tarde se revela que Metatrón le ordenó a Gadreel que perdonara a Hannah para que pudiera informar a Castiel sobre lo sucedido. Hannah se convierte en la segunda al mando de Castiel, ayudándolo a formar un ejército de ángeles en la guerra contra Metatrón. En "Escalera al Cielo", Hannah convence a Dean de que se acerque civilizadamente a Tessa, quien ha sido utilizada por Metatrón como terrorista suicida. Se enfurece cuando Dean aparentemente mata a Tessa con la Primera Espada (aunque esta última en realidad se suicidó) y se enfurece aún más al enterarse por la transmisión de Metatrón de que Castiel había mentido sobre su menguante gracia. Hannah y los demás ángeles aliados de Castiel se unen al ejército de Metatrón cuando este se niega a matar a Dean en represalia por la muerte de Tessa. Durante la llegada de Castiel y Gadreel al Cielo para destruir la tablilla angelical de Metatrón en "¿Crees en los milagros?", Hannah los atrapa y los encierra en la prisión celestial. Se niega a creer que matar a Metatrón restauraría el orden, acusando a Castiel y Gadreel de mentir y egoísmo, respectivamente. Sin embargo, se convence cuando Gadreel se suicida para demostrar su fidelidad a los humanos y se une a Castiel en su insurrección contra Metatrón. Finalmente, ambos logran derrotar a Metatrón, quien es encarcelado, aunque Hannah advierte a Castiel al final que su menguante gracia resultará en su muerte.

Tras la caída de Metatrón, Hannah se encarga de devolver a todos los ángeles caídos al Cielo. Contacta con Castiel para que la ayude a traer de vuelta a los ángeles renegados Daniel y Adina, que se han acomodado a la vida en la Tierra. Aunque Hannah no consigue devolverlos con su muerte, Castiel decide acompañarla en su misión. Entre ellos surge una relación romántica, y Hannah se vuelve tan protectora con Castiel que le propone matar a un ángel renegado y ofrecerle su gracia (él se niega). Sin embargo, cuando se encuentra con su huésped, el marido de Caroline, que busca a su esposa, Hannah se da cuenta de que Caroline merece disfrutar de su vida mortal. Tras decidir que ha disfrutado de su tiempo en la Tierra, Hannah libera a Caroline de su gracia, no sin antes besar a Castiel; inspirado por su decisión, Castiel contacta con la familia de su huésped, Jimmy Novak.

Tras abandonar a su recipiente principal, Caroline, Hannah tomó a un hombre como su nuevo recipiente. Bloquea la entrada de Sam y Castiel al Cielo para liberar a Metatrón, y cuando ambos logran burlar el plan con la ayuda de Bobby, ella y varios ángeles más acorralan a Bobby para castigarlo. Según Metatrón en "El Libro de los Condenados", Hannah ha estado al frente del Cielo desde su caída y que este se encuentra en su mejor momento desde las desapariciones/muertes de los arcángeles. En "Forma y Vacío", Hannah salva a Castiel de la tortura de dos ángeles, pero él pronto se da cuenta de que es una artimaña para que ella pueda obtener información sobre los Winchester. Los otros dos ángeles intentan "hackear" el cerebro de Castiel, lo que incomoda a Hannah. Mientras los ángeles discuten, Castiel cae nuevamente bajo la influencia del Hechizo Perro de Ataque de Rowena MacLeod y se libera. En la pelea que sigue, Hannah es asesinada por el ángel Efram por su interferencia, pero Castiel mata a Efram y a su compañero Jonah a su vez.

Joshua es un ángel descrito como el jardinero del Cielo, interpretado por Roger Aaron Brown y Paul Barton. Tras la partida de Dios del Cielo, Joshua es el único ángel con el que Dios aún habla, aunque él mismo aclara que es más bien que Dios le habla a él, no que mantienen una conversación, y sugiere que se debe a que puede entenderse "de jardinero a jardinero".

Joshua aparece por primera vez en el episodio "Dark Side of the Moon" de la quinta temporada, donde Castiel les ordena a los Winchester que lo encuentren después de que son asesinados y terminan en el Cielo. Castiel ve en Joshua la mejor oportunidad para encontrar a Dios o, al menos, para comprender su mensaje, debido a la gran cantidad de rumores sobre la comunicación entre Joshua y Dios. Los esfuerzos de los Winchester por encontrar a Joshua son interrumpidos por Zacarías, quien pretende torturarlos para que Dean acepte ser poseído por el arcángel Miguel. Sin embargo, Joshua interviene, enviado por Dios. Joshua logra que Zacarías retroceda y transporta a los Winchester al Jardín Celestial. Allí, Joshua revela que, si bien Dios los salvó cuando Lucifer resucitó a Castiel, no tiene intención de volver a hacerlo y quiere que se retiren. Joshua se compadece de ellos, diciéndoles que desearía poder hacer más, "pero solo me encargo de podar los setos". Joshua resucita a Sam y Dean, dejando intactos sus recuerdos del viaje al Cielo por orden divina.

En el episodio "En algún lugar entre el cielo y el infierno" de la temporada 12, el ángel Kelvin le revela a Castiel que Joshua ha asumido un papel de liderazgo en la búsqueda del hijo Nephilim nonato de Lucifer. Kelvin le propone a Castiel unirse a la búsqueda de los ángeles, diciéndole que si lo hace, Joshua podrá conseguir que Castiel sea perdonado por sus crímenes. Tras advertir a los Winchester sobre el Príncipe del Infierno, Dagon, Castiel viaja al Cielo con Kelvin para reunirse con Joshua.

En "El Futuro", Castiel lidera un ataque con el Colt para asesinar a Dagon y a Kelly Kline, la madre del hijo de Lucifer, siguiendo las órdenes de Joshua. La misión culmina con la captura de Kelvin y la muerte de otro ángel, pero Castiel no se atreve a matar a Kelly y, en su lugar, la secuestra. Joshua le ordena a Castiel, a través de la "radio angelical", que lleve a Kelly al portal al Cielo, ya que atravesarlo les costará la vida tanto a ella como a su hijo. Al llegar al portal, Joshua aparece para recibirlos. Sin embargo, Dagon lo reduce a cenizas momentos después. Tras asesinar a Joshua, Dagon revela que Kelvin le había contado su plan B y que había esperado durante horas para emboscar a los ángeles cuando llegaran al portal.

Lucifer, interpretado principalmente por Mark Pellegrino , Jared Padalecki , Misha Collins , Rick Springfield y David Chisum , es el segundo arcángel más antiguo, el primer ángel caído, presentado como personaje recurrente en la quinta temporada de la serie. Desde su prisión en el infierno, orquestó eventos no solo vistos en las temporadas 1 a 4, sino décadas antes, para finalmente conducir a su liberación al romper los 66 sellos . En el episodio " Sin City ", fue descrito como el "padre" y Dios de los demonios, aquel que les dio su forma y propósito. Azazel reforzó esto al referirse a él como "Mi Padre" mientras poseía a un sacerdote antes de masacrar a un convento de monjas. Sin embargo, en "Abandon All Hope", Crowley comenta que Lucifer ve a los demonios con desprecio y como carne de cañón, y los destruirá una vez que haya eliminado a la humanidad.

En el episodio "El Fin", Lucifer afirma que su caída fue el resultado de negarse al decreto de Dios de amar a los humanos más que a él. Como consecuencia, Dios ordenó a Miguel que lo arrojara al infierno. Ruby también revela en "Cuando el Dique se Rompe" que, desafiando a Dios, convirtió a Lilith en el primer demonio. Tanto la Muerte como Gabriel han comparado el odio de Lucifer hacia los humanos con "un gran berrinche" porque Dios favoreció a los humanos sobre él, su ángel más amado. A Lucifer no le gusta cómo los humanos han cambiado el planeta de su estado original y espera purificarlo. También es muy crítico con los humanos, sobre todo por cómo lo culpan de sus propios errores, malas acciones, defectos y fracasos. El creador Eric Kripke lo ha comparado en broma con una versión "psicótica furiosa" del ecologista Ed Begley Jr. con "poder ilimitado". ^{[ 5 ]}

Debido a su naturaleza angelical y espiritual, Lucifer necesita un recipiente humano para interactuar directamente con el mundo físico. Lucifer busca a un hombre llamado Nick, cuya esposa y bebé habían sido asesinados recientemente. Como se revela en el episodio "Damaged Goods" de la temporada 14, el propio Lucifer orquestó los asesinatos a través del demonio Abraxas para poder manipular a Nick. Atormentando a Nick por la tragedia, crea ilusiones como un bebé llorando y sangre brotando de la cuna, apareciendo finalmente ante Nick en la forma de su difunta esposa Sarah. Admitiendo abiertamente su identidad ante Nick, intenta ganarse su compasión diciéndole que fue castigado por amar demasiado a Dios. Luego convence a Nick para que sea su recipiente prometiéndole vengarse de Dios por permitir que su familia fuera asesinada. ^{[ 6 ]} Sin embargo, Lucifer revela más tarde a Sam que él es el verdadero recipiente destinado. ^{[ 7 ]} Por "Abandonen toda esperanza", se muestra que el cuerpo de Nick, al ser un recipiente temporal y no su "verdadero" recipiente, es incapaz de contener el inmenso poder de Lucifer y está comenzando a desgastarse; revelado en "Dos minutos para la medianoche" tiene que consumir galones de sangre de demonio para evitar que su recipiente explote. Forma un ritual para invocar a la Muerte y cuando los Winchester, los Harville y Castiel llegan, atrapa a Castiel en aceite sagrado y envía a Meg tras los demás. Después de ser emboscado por los hermanos, recibe un disparo con el Colt pero sobrevive; luego revela su condición de una de las cinco cosas en la creación inmunes al Colt; mientras los hermanos escapan con la ayuda de Castiel, logra invocar a la Muerte y someterla a su control.

Durante una convención de dioses paganos en "El Martillo de los Dioses", Mercurio le revela a Lucifer la ubicación de los hermanos y los traiciona. Tras masacrar a todos los dioses, Lucifer se acerca a los hermanos, pero Kali lo detiene hasta que llega Gabriel. Gabriel les proporciona un paso seguro a Kali y a los hermanos, y confronta a Lucifer sobre el verdadero motivo de su rebelión, alegando que no se rebeló porque reconociera la imperfección humana, sino porque ya no era el hijo predilecto de su padre. Lucifer cuestiona la lealtad de Gabriel, pero este responde que cree —basándose en su experiencia con ellos— que los humanos, a pesar de sus defectos, se esfuerzan por dar lo mejor de sí mismos. Finalmente, Lucifer mata a Gabriel con su propia espada cuando el intento de este de sorprenderlo con un duplicado fracasa, pero queda visiblemente consternado por ello.

Tras adquirir los cuatro anillos del Jinete (que pueden atrapar a Lucifer de nuevo en su prisión), Sam y Dean entran en el escondite de Lucifer, con la intención de atraparlo cuando Sam acepte ser su recipiente; esto fracasa por completo, ya que Lucifer es demasiado poderoso para luchar. Lucifer trae consigo a cuatro demonios, que habían formado parte de la vigilancia de Azazel sobre Sam desde su juventud, y los mata a todos para "desahogarse" y ganarse la confianza de Sam. Después, se enfrenta a Michael en un cementerio, intentando convencerlo de que no luche, argumentando que no tiene sentido, pero Michael se niega. Dean interviene, mientras Castiel disipa a Michael, un acto que Lucifer se toma con recelo, y lo mata. Comienza a golpear a Dean y cuando Bobby intenta usar el Colt para detenerlo, también muere. Sin embargo, Sam ve entonces un soldadito de juguete en un cenicero del Impala, un recuerdo de su juventud, y recupera el control. Sam vuelve a abrir el agujero y salta dentro, llevándose a Michael consigo.

Lucifer regresa en la séptima temporada como parte de las alucinaciones de Sam, causadas por los recuerdos de su tiempo en la jaula. Lucifer le dice a Sam que el mundo en el que ha estado durante el último año no es real y que Sam sigue en la jaula, una nueva forma de tortura de la que Lucifer se enorgullece como la mejor hasta ahora. Sam confronta a Lucifer y le pregunta por qué no termina con este mundo onírico, a lo que Lucifer responde que solo lo hará cuando Sam no pueda soportarlo más. Más tarde, Lucifer se transforma en Dean y engaña a Sam para que abandone la casa de Bobby. Una vez en el destino, se revela para demostrar que puede controlar el "sueño" de Sam, aunque se demuestra que Lucifer es una alucinación cuando Dean le explica a Sam cómo discernir la realidad. A pesar de ser una alucinación, le informa a Sam que no irá a ninguna parte. Lucifer tortura a Sam privándolo del sueño al despertarlo repetidamente y luego haciendo que la comida parezca gusanos en un intento de matarlo. Aunque Sam inicialmente logra ignorar la alucinación, esta empeora cuando acepta el consejo de Lucifer al intentar obtener información sobre el paradero de Dean, lo que intensifica la alucinación. Castiel, quien se encuentra con vida, intenta reconstruir la barrera mental de Sam, pero fracasa, ya que esta ha desaparecido por completo. Para salvar a Sam y expiar sus pecados, Castiel transfiere el problema a sí mismo, dejándolo atormentado por Lucifer y atrapado en un hospital psiquiátrico. En "Leer es fundamental", cuando Castiel sale de su estado catatónico, Sam le pregunta sobre haber visto a Lucifer. Castiel explica que sí lo vio al principio, pero que Lucifer finalmente desapareció. Castiel cree que Lucifer era simplemente una proyección del propio tormento de Sam durante su estancia en el Infierno, y que dicha proyección desapareció cuando el tormento dejó de estar presente en la mente de Sam.

En el episodio "Adiós, extraño" de la octava temporada, se revela que Lucifer poseía una serie de criptas repartidas por Estados Unidos y posiblemente por todo el mundo, donde guardaba sus artefactos más preciados. Su ubicación solo era conocida por Lucifer y sus seguidores más leales, como Azazel. Entre los objetos de sus criptas, en una caja a prueba de ángeles, se encontraba la tablilla de la Palabra de Dios. Finalmente, Sam, Dean y Castiel localizan la cripta correcta con la ayuda de Meg, quien conoce la historia gracias a su experiencia con Azazel, y consiguen la tablilla.

En el episodio " Brother's Keeper " de la décima temporada, la Muerte explica que Lucifer y los demás arcángeles libraron una guerra contra un antiguo mal llamado la Oscuridad, al que finalmente encerraron. A Lucifer se le impuso la Marca de Caín , el candado de la prisión de la Oscuridad, y la Marca lo corrompió, provocando celos hacia la humanidad y su caída en el mal. La primera mención de la actividad de Lucifer (y Miguel) desde su encarcelamiento en el Infierno se encuentra en "Out of the Darkness, Into the Fire", cuando un ayudante de Crowley le informa que, desde que la Oscuridad escapó de su prisión, los dos arcángeles han estado gritando, intentando advertir a los demás sobre el peligro que la Oscuridad representa para el mundo.

En "Oh Brother, Where Art Thou?" y "The Devil in the Details", Sam viaja al Infierno para hablar con Lucifer, guiado por lo que cree que son visiones de Dios. Manifestándose en la forma de Nick, Lucifer es invocado a una jaula más pequeña en el Infierno donde le dice a Sam que puede derrotar a la Oscuridad, pero necesita que Sam sea su recipiente nuevamente. Después de que la protección falla repentinamente, Lucifer teletransporta a Sam a la jaula y revela que le envió las visiones después de que la liberación de la Oscuridad dañara su jaula y que está trabajando con Rowena. Lucifer le muestra a Sam varios recuerdos, explicándole que si bien Sam alguna vez tuvo la fuerza para hacer lo que se necesitaba hacer, la perdió después de que Dean fue al Purgatorio. Sam acepta que Lucifer dice la verdad, pero se niega a aceptar la posesión nuevamente, ya que sabe que sin importar quién gane, Lucifer o la Oscuridad, la humanidad está condenada. Lucifer se enfrenta a Sam, Dean y Castiel en batalla, demostrando ser más que un rival para los tres juntos. Tras confirmar Lucifer que puede derrotar a la Oscuridad, Castiel acepta ser poseído por él. En ese mismo instante, Rowena completa un hechizo que aparentemente destierra a Lucifer de vuelta a su jaula. Después de que los Winchester se marchan, Lucifer, poseyendo a Castiel, se revela ante Rowena y Crowley y mata a Rowena para que no pueda enviarlo de vuelta a la jaula.

En "Into the Mystic", Dean encuentra a Lucifer buscando en el búnker una forma de invocar a la Oscuridad y le confiesa su conexión con Amara, creyendo que Lucifer es Castiel. Lucifer consuela a Dean sobre esta conexión, aunque secretamente está interesado en este descubrimiento.

En "El Recipiente", Lucifer ha recuperado el control del Infierno y mantiene a Crowley como su mascota. Tras recibir una llamada de los Winchester, se sorprende al descubrir que una de las Manos de Dios sobrevivió y acepta transportar a Dean a un submarino en 1943 para recuperarla antes de que se hunda. Un encantamiento especial mantiene a Lucifer fuera del submarino, y él y Sam intentan encontrar la manera de eliminarlo. Sam encuentra un hechizo, pero no cree que funcione, ya que requiere el poder de un arcángel. Cuando Sam ofrece su alma para ayudar a "Castiel" a obtener el poder que necesita, Lucifer se revela e intenta destruir a Sam. Castiel recupera el control temporalmente, pero no puede expulsar a Lucifer, pues le cuesta toda su fuerza impedir que mate a Sam, y solo Lucifer tiene el poder de rescatar a Dean. Cuando Delphine Seydoux desata el poder de la Mano de Dios, Lucifer trae a Dean de vuelta al presente y se revela ante él. Lucifer lanza a Dean por todo el búnker e intenta usar el poder de la Mano de Dios, pero lo encuentra agotado. Mientras Lucifer se acerca a Dean, Sam usa un sigilo de sangre para expulsarlo del búnker.

Tras su destierro, Lucifer intenta encontrar otra Mano de Dios a través de Crowley en " Más allá de la estera ". Para ello, prepara a Crowley para que sea "liberado" por Simmonds, el demonio leal de Lucifer, y así Crowley lo guíe hasta otra Mano de Dios. Crowley lleva a Lucifer hasta la Vara de Aarón, pero anticipa su traición. Crowley intenta matar a Lucifer con el poder de la Vara, pero Simmonds recibe el impacto, salvando a Lucifer. Al darse cuenta de que el poder de la Vara se ha agotado, Crowley se teletransporta rápidamente antes de que Lucifer pueda matarlo. En "El ángel del infierno ", Lucifer entra en el Cielo, mata a un ángel que encuentra allí e intimida a los demás ángeles para que lo sigan a combatir a Amara. Amara desata una ola de oscuridad por el Cielo, aterrorizando a los ángeles y empujándolos a seguir a Lucifer. Sin embargo, los Winchester, Crowley y la aún viva Rowena se unen para liberar a Castiel y desterrar a Lucifer de vuelta a su Jaula. Para ello, lo invocan a un conjuro en una iglesia rodeada de Fuego Sagrado. Una vez atrapado Lucifer, Dean intenta usar magia para suprimir al arcángel y restaurar a Castiel, pero Lucifer rápidamente lo domina. En un intento desesperado, Crowley entra en el cuerpo de Castiel, donde descubre que Lucifer se ha ensañado con él, mostrándose apático ante todo lo que le rodea, incluso cuando Lucifer aparece en forma de Nick y ataca a Crowley. Sam exorciza a Crowley para salvarle la vida y el conjuro se rompe, liberando a Lucifer. Lucifer consigue el Cuerno de Josué de los Winchester, otra Mano de Dios, justo antes de que aparezca Amara. Lucifer ataca a Amara con su propio poder y el del Cuerno, pero sin éxito. Amara captura a Lucifer y lo lleva a un silo de grano que usa como base. Creyendo que Lucifer es lo único que aún le importa a Dios, Amara comienza a torturarlo con la esperanza de provocar su reacción.

Over the next few weeks, Amara tortures Lucifer mercilessly, trying and failing to draw out God. In "All in the Family", Amara notices that Lucifer is in bad shape along with Castiel and contacts Dean to pass on the message to God. Having learned that God intends to sacrifice Himself to Amara to save the universe, the Winchesters, Metatron and Prophet Donatello Redfern team up together to rescue Lucifer, hoping to convince God to use Lucifer in battle against Amara. As Dean distracts Amara, Sam, Metatron and Donatello find the heavily injured Lucifer who agrees to set aside his differences with God and fight Amara with them. They set him free, but he is too weakened to teleport them to safety. As Amara approaches, Metatron sacrifices himself to buy them time to get away, but Amara quickly catches up to them. Before she can kill the group, God teleports them and the Impala into the Bunker. There, for the first time in millennia, God and Lucifer are reunited. After commenting on how much each other has changed, God heals Lucifer's injuries to the fallen archangel's surprise.

En " We Happy Few ", Lucifer se enfurruña en el búnker, disgustado por haberse reunido con Dios, quien no se disculpa con él. Hartos de sus problemas, los Winchester logran que Dios y Lucifer se reúnan. Al principio, la situación es tensa, pero finalmente se reconcilian. Ahora completamente de su lado, Lucifer se une a Dios para explicar que la última vez que derrotaron a la Oscuridad, los cuatro arcángeles y Dios apenas lograron la victoria, y esta vez Miguel no está en condiciones de luchar, Gabriel y Rafael están muertos y Dios no puede resucitarlos. Por lo tanto, los Winchester sugieren pedir ayuda a las brujas, ángeles y demonios. Como Dios se niega a ordenar a los ángeles que ayuden, Lucifer regresa al Cielo, donde los ángeles se niegan a escucharlo. En respuesta, Lucifer le devuelve el control a Castiel, quien les dice a los ángeles que Lucifer se está consumiendo a sí mismo y a su cuerpo, pero que siente que su papel en la batalla es darle forma a Lucifer en la Tierra para luchar. Castiel y Lucifer logran convencer a los ángeles para que se unan a ellos, y Sam y Dean logran convencer a las brujas y demonios respectivamente. Después de que las brujas, ángeles y demonios atacan a Amara, ella entra al almacén donde los Winchester, Dios y Lucifer la esperan, y Lucifer la ataca por la espalda con una lanza angelical. Debido a su estado debilitado, el ataque de Lucifer la derriba y ella y Dios se enfrentan. Sin embargo, Dios tarda demasiado en transferir la Marca de Caín a Sam, y Amara se recupera y ataca a Dios con todo su poder. Lucifer intenta salvar a su padre, pero Amara lo lanza contra un pilar y lo arranca de Castiel, dejándolo inconsciente. En " Alfa y Omega ", Dean va a ver a Lucifer solo para encontrar a Castiel solo. Castiel le dice que Lucifer ha salido de su cuerpo, pero no sabe qué le sucedió al arcángel después de que Amara lo sacara.

En " Keep Calm and Carry On ", un Lucifer debilitado busca un nuevo recipiente adecuado perseguido por Crowley, pero sigue consumiendo a las personas que posee. En " Mamma Mia " , Lucifer se decide por la estrella de rock envejecida Vince Vincente (Rick Springfield) y obtiene permiso haciéndose pasar por el amante muerto de Vince. Con un nuevo recipiente permanente, Lucifer se reúne con Crowley, quien trabaja con Rowena en un intento de obligar a Lucifer a separarse de Vince y regresar a la Jaula. Sin embargo, el esfuerzo fracasa y Crowley huye mientras Lucifer captura a Rowena. En " The Foundry" , Lucifer intenta que Rowena convierta a Vince en un recipiente permanente para él, pero ella lo traiciona y lanza un hechizo que acelera la descomposición de Vince y destierra a Lucifer al fondo del océano. En "Rock Never Dies", un par de satanistas aficionados intentan invocar a Lucifer, quien aparece en el cuerpo en descomposición de Vince. Lucifer fue invocado por una de sus plumas y mata a los satanistas, luego usa la pluma para reparar su cuerpo temporalmente. Haciéndose pasar por Vince, Lucifer organiza un concierto para asesinar a mucha gente y se enfrenta a los Winchester, Crowley y Castiel, quienes son incapaces de derrotarlo. Lucifer les explica que siente que Dios solo se reconcilió con él para derrotar a la Oscuridad y lo ha abandonado una vez más. Lucifer ya no tiene otro plan que destruir todo lo que quiere y abandona a Vince mientras su cuerpo se consume. En "LOTUS", Lucifer comienza a poseer a personas influyentes, poseyendo finalmente al presidente de los Estados Unidos, Jefferson Rooney. Como presidente, Lucifer envía al Servicio Secreto tras los Winchester y tiene relaciones sexuales con la amante de Rooney, Kelly, lo que resulta en que ella quede embarazada de su hijo. Crowley secuestra a Kelly, quien engaña a Lucifer para llevarlo a un motel donde los Winchester, Castiel, Crowley y Rowena lo esperan. Tras usar un sigilo para debilitar a Lucifer, Sam activa un dispositivo creado por los Hombres de Letras británicos capaz de exorcizar a cualquier ángel o demonio de su cuerpo. A pesar de los intentos de Lucifer por resistirse, es exorcizado de Rooney y Rowena lanza un hechizo que, aparentemente, lo devuelve a su jaula.

En la Comic-Con de San Diego de 2016, se afirmó que lo único que Lucifer desea es unas "vacaciones", ya que está cansado de gobernar tanto el Cielo como el Infierno y feliz de haberse reconciliado finalmente con su padre.

Pronto se revela que Lucifer no fue desterrado de vuelta a la Jaula, sino que fue transferido de nuevo a Nick; Crowley recuperó el cadáver de Nick y un equipo de demonios lo "reparó", convirtiendo a Nick en una nueva Jaula donde Lucifer no puede abandonar su recipiente y solo puede usar sus poderes bajo las órdenes de Crowley. Lucifer finalmente logra darle la vuelta a la situación y escapar de su cautiverio (aunque aparentemente sigue atrapado en Nick), con los intentos de los Winchester por detenerlo desterrándolo a un universo paralelo donde tuvo lugar el Apocalipsis porque Dean y Sam nunca nacieron, aunque Lucifer es confrontado por Crowley, quien se suicida para atraparlo, logra matar a Castiel y llevarse a Mary con él. Mientras los Winchester intentan "criar" al hijo de Lucifer, Jack, quien creció hasta la edad adulta inmediatamente después de nacer, Jack logra ayudar a Castiel a volver a la vida, pero Lucifer permanece en el otro mundo y alerta al Michael alternativo de su existencia, lo que lo impulsa a luchar contra el Michael alternativo, pero es derrotado. Mientras está encarcelado, Alt-Michael le roba sus poderes y le revela sus planes de viajar al universo principal para conquistarlo también. Ante esta amenaza, Lucifer utiliza un ritual realizado por Michael para regresar a su mundo y advertirles sobre él, pero Castiel inicialmente no le cree antes de que Asmodeus los capture, aunque logran escapar. Lucifer toma el control del Cielo, ya que hay muy pocos ángeles para oponer una resistencia efectiva a Michael. Más tarde, lo abandona para buscar a su hijo, pero no tiene éxito.

Durante "Vence al Diablo", ahoga sus penas antes de ser capturado de nuevo, pero por Gabriel y Rowena, quienes sobrevivieron a sus intentos de asesinato. Su gracia se usa para alimentar la grieta y mantenerla abierta. Lucifer se entera por una burlona Rowena de que su hijo está en ese mundo y se libera. El intento de Lucifer de asesinarla termina enviándolo al Mundo del Apocalipsis, donde resucita a Sam, quien fue asesinado por vampiros, habiendo usado la gracia de los soldados de Miguel para recargarse. Obliga a Sam a ayudarlo a formar un vínculo con su hijo. Lucifer conoce a su hijo por primera vez.

During "Exodus", Lucifer bonds with Jack and is reluctantly allowed to join the team, revealing that they have thirty-one hours before the rift closes again and killing six attacking angels. During this time, Lucifer's efforts to paint himself in a better light are rebuffed by Gabriel who compares his older brother to a cancer that God had to cut out to protect humanity, but too late. Gabriel's words reduce Lucifer to silent tears. Lucifer later works with Dean to repair an old bus and then drives the bus full of refugees back to the rift. When Michael appears and attacks during the exodus through the rift, Lucifer attacks him, but is easily beaten. Following Gabriel's death at Michael's hands, an injured and weakened Lucifer tries to follow Sam through the rift but is thrown to the ground by the younger Winchester and abandoned to die. With the rift closed, Lucifer makes a deal with Michael to share the spell to reopen it in exchange for Lucifer getting to take Jack while Michael gets everything else.

In the Season 13 finale "Let the Good Times Roll", Lucifer reappears in the Winchesters' universe and entices Jack to leave for the stars with him. At the request of Jack, Lucifer resurrects his friend Maggie who subsequently identifies Lucifer as her killer. During a confrontation with Michael, Lucifer's deal with the other archangel is revealed as is his murder of Maggie. Lucifer is forced to admit the truth by Jack who rejects his father after seeing his true nature. Enraged, Lucifer absorbs his son's grace to become more powerful than ever. With Lucifer virtually unstoppable and poised to destroy everything, Dean agrees to become the vessel of the alternate Michael on the condition that Michael power him to battle Lucifer. Powered by Michael, Dean battles Lucifer who still proves to be more than a match for Dean. However, as Lucifer tries to smite Dean, Sam is able to toss Dean the Archangel Blade, the one weapon that can kill an archangel. Armed with the blade, Dean is able to finally kill Lucifer by stabbing him in the heart. However, in the aftermath of Lucifer's death, Michael betrays his deal with Dean, takes full control of him and disappears.

In the Season 14 episode "Stranger in a Strange Land", Lucifer's vessel Nick is revealed to have survived Lucifer's death. Nick has nightmares and flashbacks to his time as Lucifer's vessel and a slowly healing wound in his side where Lucifer was stabbed. Sam and Mary both have trouble looking at Nick due to his time under Lucifer's control, but he is able to tell Sam that Michael had told Lucifer that he wants to "do it right this time" when discussing his plans for the Winchesters' world. Nick subsequently shows Lucifer-like behaviors when angered in "Gods and Monsters", causing Castiel to suspect that Lucifer did more damage to Nick's psyche than was previously realized.

En "Naturaleza inhumana", la sangrienta sed de venganza de Nick lo lleva a convertirse en un asesino en serie . Tras matar a Frank Kellogg, el hombre poseído por el demonio Abraxas cuando este asesinó a su familia, Nick reza a Lucifer, dándose cuenta de que disfrutaba ser el recipiente del arcángel y de la libertad que ello conllevaba. En respuesta a la plegaria de Nick, una figura con ojos rojos brillantes emerge del Vacío, presumiblemente el propio Lucifer, despertado de su sueño eterno por la oración de Nick.

En "Mercancías Dañadas", Nick logra dar con el demonio Abraxas, quien asesinó a su familia. Durante un enfrentamiento, Abraxas le revela a un Nick atónito que fue el propio Lucifer quien ordenó la muerte de su familia a manos de Abraxas. Abraxas le dice a Nick que, si bien él fue elegido, Nick no era nada especial y que "lanzaron un dardo a la guía telefónica" para elegirlo. Enfurecido, Nick mata a Abraxas con una espada angelical en venganza por el asesinato de su familia. Durante el enfrentamiento, a pesar de haber sido leal a Lucifer, al demonio no le importa realmente que Lucifer esté muerto, simplemente responde que es "genial" cuando Nick se lo cuenta a Abraxas, quien también se divierte al saber que Nick ya no está bajo el control de Lucifer.

En «Profeta y pérdida», Nick comienza a buscar a Lucifer para reunirse con él. En «Noche de juegos», Nick secuestra al profeta Donatello Redfield y, potenciando sus habilidades con la gracia de un ángel, se comunica con Lucifer, quien ha despertado en el Vacío. Lucifer le ofrece a Nick una forma de resucitarlo usando la sangre de su hijo. Nick consigue la sangre y realiza el hechizo, abriendo un portal al Vacío del que emerge Lucifer en forma de una viscosa figura humanoide negra con alas. Sin embargo, Jack llega con Mary Winchester, mata a Nick y destierra a Lucifer de vuelta al Vacío.

En "Ausencia" y "Jack in the Box", Jack es atormentado por una alucinación de Lucifer, la forma que adopta su subconsciente después de que Jack mata accidentalmente a Mary.

En el episodio "Proverbios 17:3" de la temporada 15, Sam experimenta una visión, parte de una serie de pesadillas recurrentes, en la que Lucifer lo posee y viste un traje blanco, tal como lo hizo en "El Fin". Dean intenta matar al arcángel con el Colt, pero Lucifer sale ileso del disparo y quema a Dean hasta la muerte tras afirmar que ambos siempre supieron que tenía que terminar así. Más tarde, Sam llega a la conclusión de que está presenciando los posibles finales que Chuck tiene planeados para ellos. En "La Trampa", se revela que se trata del Lucifer de una realidad alternativa, y Chuck explica que lo que Sam presenció en realidad fueron los recuerdos de Chuck sobre versiones alternativas de Sam y Dean.

En el penúltimo episodio de la serie, "Heredar la Tierra", un Lucifer resucitado aparece en el búnker, afirmando que la Sombra lo trajo de vuelta para ayudar a los Winchester a derrotar a Dios. Como prueba, Lucifer mata a Betty, una segadora, para que se convierta en la nueva Muerte y pueda leer el libro de la Muerte de Chuck. Sin embargo, una vez que Betty abre el libro, Lucifer la mata y revela que en realidad fue Dios quien lo trajo de vuelta para obtener el libro y que Lucifer es el nuevo favorito de Dios. Lucifer se enfrenta brevemente a Michael en una batalla que termina cuando Michael logra matarlo con una Espada de Arcángel que Sam le proporciona. Esta vez, Lucifer explota en cenizas sin dejar rastro. Más tarde, Sam y Dean le explican a Chuck que Jack absorbió el poder de la batalla entre Michael y Lucifer y de la segunda muerte de Lucifer, y que la reacción de Michael ante las afirmaciones de Lucifer les permitió elaborar su plan definitivo.

Como homenaje a El paraíso perdido de John Milton , Lucifer será retratado como "gentil, casi compasivo". ^{[ 8 ]} Kripke razonó: "Fue esencialmente traicionado, así que en cierto modo se le puede ver con compasión... si podemos hacer que los ángeles sean unos cretinos, Lucifer puede ser compasivo". ^{[ 9 ]} Kripke lo caracterizó además como un "Diablo que tiene dudas" y "mucho afecto por Dios y los ángeles", y que "habla con mucha ternura y gentileza y... no miente". ^{[ 8 ]}

Pellegrino fue la segunda opción para interpretar al ángel Castiel, perdiendo el papel ante Misha Collins. ^{[ 10 ]}

Metatrón , interpretado por Curtis Armstrong , es el ángel que escribió las tablas de la Palabra de Dios. Según la tabla demoníaca, es un Arcángel, pero Metatrón afirma ser un ángel de la división secretarial que Dios reclutó para escribir las tablas antes de abandonar el Cielo. Dios afirma más tarde que no tenía ninguna razón especial para elegir a Metatrón y que este simplemente era el ángel más cercano a la puerta cuando entró. Cuando Dios se fue y los Arcángeles decidieron tomar el control, Metatrón abandonó el Cielo y se escondió en la Tierra para protegerse a sí mismo y a las tablas, pues supuso correctamente que los Arcángeles lo necesitarían para cumplir sus planes. En la Tierra, Metatrón vivió entre una tribu nativa americana conocida como Los Dos Ríos, a quienes otorgó la inmortalidad a cambio de historias y libros. Metatrón quedó fascinado por las historias humanas y, aunque leyó tanto como un ángel podía, no fue capaz de leer todas las historias escritas durante sus milenios en la Tierra.

Sam y Dean se enteran de Metatrón cuando descubren la tablilla de la Palabra de Dios de los Leviatanes y Castiel revela que Metatrón las escribió. Dean considera buscarlo para que lo ayude con los Leviatanes. Más tarde, Kevin Tran encuentra una nota personal que Metatrón dejó en la tablilla demoníaca, revelando la existencia de un compendio de tablillas. Mientras intentan encontrar la tercera prueba para cerrar el Infierno, Sam y Dean localizan a Metatrón y lo confrontan. Metatrón inicialmente se niega a ayudar, pero después de que le revelan la historia de Kevin Tran, Metatrón lo rescata de Crowley y lo cura. Metatrón ahora sabe lo que está sucediendo en el Cielo y en el mundo y acepta ayudar. Junto con Kevin, Metatrón revela la tercera prueba: curar a un demonio. Le sugiere a Dean que debe considerar el impacto que tendrá el cierre del Infierno en el mundo. Más tarde, Metatrón se acerca a Castiel para pedirle ayuda para lidiar con los problemas en el Cielo. El Cielo se ha degenerado en una guerra de facciones y Metatrón quiere aislarlo. Como Escriba de Dios, conoce las tres pruebas sin la tablilla angelical, pero quiere que Castiel las lleve a cabo. Los dos intentan la primera prueba, que consiste en matar a un Nefilim y arrancarle el corazón. Aunque Castiel duda, cuando el Nefilim los domina a ambos, la mata por la espalda mientras está distraída con Metatrón. En "Sacrificio", Metatrón revela que la segunda prueba consiste en conseguir el arco de Cupido y, mientras trabaja con Castiel en la tarea, Naomi lo captura. Metatrón reconoce a Naomi como el ángel que debía "informarle" a los Arcángeles después de que Dios se marchara, aunque el verdadero propósito era descubrir sus secretos. Sospechando de por qué Metatrón ha salido de su escondite, Naomi lo tortura y se sorprende al descubrir que en realidad pretende expulsar a todos los ángeles del Cielo (excepto a sí mismo) como venganza por su propia expulsión. Naomi advierte a Dean y Castiel, pero mientras ella está ausente, Metatrón se libera y mata a Naomi cuando regresa. Captura a Castiel y toma su gracia como el último componente necesario para su hechizo. Lo envía a la Tierra para que viva como humano, pidiéndole que lo encuentre y le cuente lo sucedido cuando muera. El plan de Metatrón funciona y todos los ángeles son expulsados ​​del Cielo. Sam y Dean descubren en "El Cielo no puede esperar" que Metatrón diseñó el hechizo para que fuera irreversible, aparentemente sin posibilidad de que los ángeles regresen al Cielo.

Metatrón reaparece en la Tierra en "Santo Terror" durante la lucha de las facciones angelicales por hacerse con el control y decidir la mejor estrategia para regresar al Cielo. Convence a Gadreel para que se una a él en la reformulación del propósito de los ángeles, lo que resulta en la muerte de Kevin Tran y en que Gadreel controle el cuerpo de Sam.

En "Road Trip", emplea a Gadreel como su asesino, enviándolo a matar al ángel guardián Thaddeus y al amigo de Gadreel, Abner, presumiblemente como una prueba más de su lealtad. Se enfada cuando Gadreel no mata a Dean y cuestiona sus órdenes. Metatron espera a que Gadreel regrese tras matar a Abner con el antiguo cuerpo de Gadreel y se sorprende cuando Gadreel aparece repentinamente en su forma natural y recupera su antiguo cuerpo. Al darse cuenta de que Sam ha expulsado a Gadreel, un Metatron divertido le pregunta si Gadreel tuvo problemas con Winchester. Tras obtener las tablillas, Metatron se conecta a la tablilla del ángel, lo que le otorga un poder divino. Continuando con sus esfuerzos con la ayuda de Gadreel, Metatron recluta seguidores y comienza a escribir su propia "historia". Con este fin, captura a Castiel durante "Meta Fiction" y le pide que sea el villano de la historia a cambio de un suministro ilimitado de gracia, ya que su gracia robada se está agotando. Castiel se niega y Metatrón se ve obligado a intercambiarlo por Gadreel después de que Sam y Dean capturan a este último. Con sus nuevos poderes, Metatrón demuestra ser inmune a sus intentos de atraparlo. Los deja ir, ya que no los considera una amenaza.

Tras esto, Castiel reúne a sus propios seguidores para luchar contra Metatrón. Metatrón ordena a Gadreel que elimine a otros ángeles que podrían amenazarlo. A medida que los seguidores de Castiel se vuelven más fuertes que los suyos, Metatrón utiliza terroristas suicidas con el cerebro lavado en "Escalera al Cielo" para convencer a los demás ángeles de que no sigan a Castiel. Metatrón les ofrece a los ángeles regresar al Cielo a través de un portal móvil que ha creado a cambio de su lealtad. Después de que Castiel se niega a matar a Dean por supuestamente haber asesinado a la segadora Tessa, sus seguidores lo abandonan y se unen a Metatrón. Sin embargo, esto se vuelve en contra de Metatrón, ya que sus métodos provocan que Gadreel también cambie de bando.

Durante "¿Crees en los milagros?", tras transmitir a todos los ángeles por la "radio angelical", Metatron se dirige a la Tierra para convertir a la humanidad y que lo sigan a él en lugar de a Dios, realizando milagros, incluyendo la resurrección de los muertos. Dean, armado con la Primera Espada y potenciado por la Marca de Caín, se enfrenta a Metatron mientras Castiel y Gadreel intentan irrumpir en el Cielo y destruir el poder de Metatron. Con su nuevo poder, Metatron hiere mortalmente a Dean. Sin embargo, antes de que pueda rematarlo, el sacrificio de Gadreel permite a Castiel romper la tablilla angelical y aniquilar el increíble poder de Metatron, obligándolo a huir del ataque de Sam. En el Cielo, Metatron ata a Castiel y se burla de él, diciéndole que los ángeles son ovejas que lo seguirán y que no le importan en absoluto. Sin embargo, Castiel había activado secretamente el equipo de transmisión en la oficina de Metatron, transmitiendo estos comentarios a todos los ángeles. Los seguidores de Metatron se rebelan y lo dominan, pero Castiel lo encierra en el calabozo del Cielo en lugar de matarlo. El asesinato de Dean provoca que resucite como demonio.

En "Reichenbach", Hannah se acerca a Metatron para ver si le queda algo de la gracia de Castiel con la esperanza de salvarlo de morir cuando su gracia robada se agote. Metatron afirma que aún le queda algo y se ofrece a entregársela a cambio de su libertad, asegurando que abandonará el planeta si lo liberan. Castiel se niega y Metatron revela que en realidad planea vengarse una vez que escape, aunque afirma que aún le queda algo de gracia. En "Los Juegos del Cazador", con la esperanza de que Metatron conozca una cura para la Marca, Castiel lo hace traer a la Tierra, donde él y los Winchester lo interrogan para obtener información. Metatron afirma que hay una cura para la Marca y que requiere la Primera Espada, pero cuando Dean exige el resto, revela que hay muchos pasos y que quiere algo por cada uno. Dean tortura a Metatron, quien continúa provocándolo para que ceda a la ira de la Marca, pero Castiel y Sam lo detienen antes de que pueda matarlo. Castiel regresa a Metatron al Cielo para ponerlo a salvo, y Metatron dice que elegirá la muerte antes que volver a ayudar. Sin embargo, deja una posible pista: "he aquí, el río terminará en la fuente". En "Inside Man", desesperados por encontrar una cura para la condición deteriorada de Dean, Sam, Castiel y Bobby SingerMetatron planea liberar a su prisionero cuando los ángeles se niegan a entregarlo a su custodia por temor a lo que hará si es liberado. En la Tierra, Metatron los provoca con su poder sobre ellos hasta que Castiel le quita su gracia, dejando a Metatron humano y mortal. Después de que Sam le dispara en la pierna y Castiel amenaza su vida, Metatron cede rápidamente y admite que no conoce ninguna cura para la Marca, afirmando que es un poder de nivel divino o de Lucifer y que no sabe nada, y que ni siquiera las tablillas contienen información sobre la Marca. Castiel puede darse cuenta de que Metatron dice la verdad, pero antes de que Sam pueda matarlo, Metatron les dice que decía la verdad sobre que aún queda algo de la gracia de Castiel y se ofrece a guiarlo hacia ella a cambio de su vida. Castiel acepta a regañadientes y parte en busca de su gracia con Metatron. En "El Libro de los Condenados", Metatron y Castiel hacen un viaje por carretera para encontrar la gracia de Castiel. Metatron comienza a aceptar su nueva humanidad, molestando a Castiel con sus payasadas y provocando que Metatron reciba un puñetazo. En un restaurante, son atacados por un Cupido furioso y Metatrón lo mata para salvar a Castiel, pero no logra ganarse su afecto con sus acciones. Finalmente, los dos llegan a una biblioteca donde Metatrón revela que le pidió a otro ángel que escondiera la gracia y le dejara pistas para que nadie más pudiera encontrarla ni torturarlo para obtener la información. Buscando entre los libros uno con el título "¿Cuál es la cosa más descabellada que un hombre puede hacer?", Metatrón entabla una conversación con Castiel, preguntándole qué hará una vez que encuentre a los ángeles renegados restantes, ahora que Hannah ha restaurado el orden en el Cielo. Mientras Castiel está distraído, Metatrón usa su sangre para lanzar un hechizo que lo aturde y recupera la tablilla demoníaca, lo que realmente buscaba. Sin embargo, descubre que Castiel ha encontrado su gracia en una copia de Don Quijote y se marcha rápidamente antes de que pueda recuperarse. Castiel recupera su gracia y su poder completo, pero él y Sam se quedan preocupados por lo que Metatrón puede hacer con la tablilla demoníaca a pesar de ser ahora humano. También le mienten a Dean sobre cómo Castiel recuperó su gracia, diciéndole que Hannah se la arrebató a Metatrón y sin mencionar su escape. Más adelante se menciona que escapó robando el coche de Castiel.

In "Out of the Darkness, Into the Fire" and "Into the Void", the other angels search for Metatron to reimprison him, while in "The Bad Seed", the Winchesters and Castiel join the search hoping he has information on The Darkness. To their surprise, they can find no incidents with Castiel's car that indicate that Metatron was in a crash, surprising Castiel as he did not expect a former angel and shut-in to be a good driver. In "Our Little World", Castiel spots Metatron's reflection in a photo of a murder on the news, revealing that Metatron has become a videographer. Castiel tracks Metatron down at the scene of a shooting where Metatron steals the victim's money and bemoans his lack of power that he would not have used to help the man anyway. After healing the man and breaking Metatron's camera, Castiel drags him to an abandoned warehouse where Metatron tells him he has come to see reality as literature and himself as the "author of reality" as a videographer. Metatron lies about the location of the demon tablet, but Castiel has already found it by searching Metatron's apartment where he had hidden it under his mattress. Castiel demands information on the Darkness, but Metatron refuses to spill and taunts him into attacking Metatron. Castiel stops when he realizes that Metatron wants to die and Metatron explains that he cannot stand life as a human. He finally tells Castiel that the Darkness is God's sister who He had to give up to form creation. Castiel lets Metatron go, telling Sam and Dean that he is now just a pitiful human and is no threat. If Metatron draws any sort of attention to himself, the angels will descend on him and destroy him.

In "Don't Call Me Shurley", Metatron is living as a homeless vagrant, but has gained a more compassionate nature as demonstrated by his feeding a stray dog rather than eating it food he had scavenged himself. Metatron and his dog are transported to a bar where Metatron meets with Prophet Chuck Shurley who reveals himself to be God. God does not punish Metatron for his rogue actions, though He also refuses to reinstate him as an angel, something Metatron admits is probably for the best. Instead, God asks Metatron to help Him write His autobiography. Metatron helps God but is stunned by how apathetic God has become to the world and the situation with Amara. After learning that Amara has infected a town with insanity, Metatron pleads with God to help, now understanding that humanity is God's greatest creation and is better than God because although humans have many flaws, they still try. God apparently refuses to listen, but Metatron reads the end of his autobiography and is shocked by what he reads while God intervenes to stop Amara's infection and to save the Winchesters.

En "All in the Family", Metatron contacta a los Winchester y les advierte que Dios pretende sacrificarse por Amara en un intento por salvar el universo. Deseando hacer lo posible por salvar a Dios y a la humanidad, Metatron se ofrece a ayudar a los Winchester y se une a Sam y al Profeta Donatello en una misión de rescate para Lucifer. Mientras Sam y Lucifer discuten la situación, Metatron lanza un hechizo para liberar a Lucifer de sus ataduras, pero Lucifer es incapaz de teletransportarlos a un lugar seguro. Cuando Amara se acerca, Sam, Lucifer y Donatello huyen, pero Metatron se queda atrás para darles tiempo. Metatron usa sin éxito un sigilo para desterrar ángeles, lo que divierte a Amara. Le pide que perdone al universo, ya que Dios solo tenía buenas intenciones. Diciéndole a Metatron "perdona esto", Amara lo envuelve en oscuridad y lo reduce a la nada. Después de enterarse de la muerte de Metatron, Dean se sorprende de que Metatron se haya sacrificado por ellos.

Miguel es el arcángel más antiguo y poderoso, que aparece en la quinta temporada. En el primer episodio, Zacarías revela el plan de los ángeles para que Miguel use a Dean como su recipiente y mate a Lucifer. Sin embargo, Dean debe dar su consentimiento para ser el recipiente. Miguel aparece por primera vez cuando Sam, Dean y Castiel viajan al pasado, a 1977, para impedir que Anna mate a John y Mary y así evitar el nacimiento de Sam y, por lo tanto, que sea usado como recipiente de Lucifer. Miguel se refiere a Lucifer como su hermano menor. Cuando Lucifer se negó a obedecer la orden de Dios de inclinarse ante la humanidad, buscó el apoyo de Miguel, pero fue rechazado. Por orden de Dios, Miguel arrojó a Lucifer al infierno. Cuando los ángeles idean un nuevo plan para convencer a Dean de que dé su consentimiento en "Punto de no retorno", traen de vuelta a Adam, el tercer hijo de John Winchester, con la excusa de que puede ser el nuevo recipiente de Miguel, pero esto es solo una artimaña para que Dean diga que sí. Zacarías tortura a Sam y a Adam hasta que Dean da su consentimiento. Zacarías entonces llama a Miguel del Cielo, pero Dean cambia de opinión, mata a Zacarías e intenta escapar. Adam queda encerrado inadvertidamente mientras Michael desciende, y la habitación y Adam desaparecen. En "Dos minutos para la medianoche", Castiel confirma que ahora Michael está tomando a Adam como su recipiente. Durante el episodio "Canción del cisne", Michael aparece con Adam como su recipiente para luchar contra Lucifer, pero es interrumpido por Dean, Bobby y Castiel, quienes lo retrasan enviándolo lejos con fuego sagrado. En un par de minutos regresa para ver a Sam, quien ha tomado el control de Lucifer, listo para saltar al abismo, e intenta detenerlo, afirmando que su destino es luchar contra su hermano. Mientras Sam lo niega, Michael hace un último esfuerzo desesperado por retenerlo, pero Sam lo arrastra y caen juntos al abismo. Castiel cree que él y Lucifer torturaron el alma de Sam en la jaula hasta que fue extraída por la Muerte, uno de los jinetes. La primera mención de la actividad de Michael desde su encarcelamiento en el Infierno se encuentra en "Fuera de la oscuridad, hacia el fuego " , donde un ayudante de Crowley le informa que Michael está gimiendo, tratando de advertir a otros sobre el peligro que la Oscuridad, recientemente liberada de su prisión, representa para el mundo. En "El diablo en los detalles " , Lucifer le dice a Sam que la "vida en prisión" no le ha sentado bien a Michael e indica que su tiempo en la Jaula lo ha vuelto loco. Al hablar de su próxima batalla contra la Oscuridad, Dios se hace eco de esto, diciéndoles a los Winchester que Michael no está en condiciones de luchar.

En el episodio "De vuelta al futuro" de la temporada 15, el demonio Belphegor le dice a Dean que Dios abrió todas las puertas del Infierno, incluida la de la Jaula de Lucifer. Dean pregunta por Michael y Belphegor le dice que, según su última información, Michael estaba en la Jaula. Sin embargo, Belphegor insinúa que si Michael logra escapar, buscará venganza.

En "Nuestro Padre, que no estás en el cielo", los Winchester y Castiel descubren, gracias a la tablilla demoníaca, que Dios tiene una debilidad secreta que solo compartió con su favorito. Sospechando que se trata de Michael, viajan al Infierno para hablar con él. Dean sospecha que Dios y Lucifer mintieron sobre la locura de Michael. Sin embargo, para entonces, Michael ya ha escapado de la Jaula y del Infierno y ha regresado a la Tierra, donde, en el cuerpo de Adam Milligan, comparte el control con su huésped. Con los demás arcángeles muertos y Dios ausente, Michael decide comenzar una nueva vida con Adam en la Tierra, despidiendo a Lilith cuando el demonio llega para llevarlo ante Dios. Después de que Castiel le reza, Michael acepta reunirse con su hermano, aunque no le agrada ver al otro ángel, dado el papel de Castiel en su encarcelamiento. Los Winchester y Castiel capturan a Michael e intentan convencerlo de que Dios es la amenaza y que necesitan su ayuda para detenerlo. Adam revela que él y Michael llegaron a un acuerdo en la Jaula. Michael se niega a escuchar, pues eso significaría que el Hijo Predilecto de Dios dudaría de él. En un último intento, Castiel le muestra a Michael sus recuerdos de las traiciones de Dios, incluyendo la batalla contra la Oscuridad, el asesinato de Jack y el Michael del Mundo Apocalíptico. Desilusionado, Michael les da a Castiel y Dean el hechizo para atrapar a Dios, pero les advierte que requiere una flor que solo crece en el Purgatorio. Michael abre un portal de doce horas para que vayan al Purgatorio, pero se niega a quedarse y ayudar. Dean libera al arcángel, quien permite que Adam retome el control para que Dean pueda disculparse con su hermano antes de que Adam y Michael se marchen.

En "Heredar la Tierra", los Winchester y Jack encuentran a Michael en una Tierra prácticamente vacía. Michael revela que Adán fue asesinado cuando Dios aniquiló a todos los demás. Dice que se sorprendió al saber que muchos humanos amaban a Dios. Michael revela entonces que esto se debe a que ángeles y profetas describieron a su padre como amoroso y bondadoso. Luego acepta ayudarlos contra Dios. Sin embargo, ni siquiera Michael puede abrir el Libro de la Muerte de Chuck. Poco después, Michael se enfurece al ver a un Lucifer resucitado, quien finalmente revela que Dios lo trajo de vuelta para recuperar el libro y que Michael ya no es el favorito de Dios. Michael y Lucifer se enfrentan en una breve batalla que termina con Michael matando a su hermano con una Espada de Arcángel que Sam le proporcionó. Michael se une a los Winchester y Jack en su plan para usar un hechizo del Libro de los Condenados para matar a Dios, pero los traiciona en un intento por volver a ser el favorito de su padre. Se reúne con su padre por primera vez en milenios y este le agradece su advertencia. Sin embargo, Chuck, furioso porque Michael lo traicionó anteriormente, aniquila sin esfuerzo al arcángel que protestaba, extinguiendo así a los arcángeles. Sam y Dean revelan que habían anticipado la traición de Michael y lo usaron para tenderle una trampa a Chuck y llevar a cabo su verdadero plan.

Naomi, interpretada por Amanda Tapping , es una villana "fría", "misteriosa" y "refinada" que aparece por primera vez al final del episodio "A Little Slice of Kevin".

Antes de su muerte, Samandriel había estado tratando de decirle a Castiel algo sobre Naomi, lo que desencadenó el recuerdo de Castiel en el que Naomi se acercaba a su ojo con un misterioso instrumento parecido a un taladro mientras él estaba inmovilizado y gritando.

Después de que él encuentra la tablilla y ella le ordena matar a Dean, Castiel logra resistir su control y finalmente lo rompe al tocar la tablilla.

En "Taxi Driver", Naomi se reúne con Dean para intentar convencerlo de que está de su lado, alegando que Castiel le había informado mal sobre ella debido a su inestabilidad mental, y que quiere ayudar a Castiel; Dean no le cree. Sin embargo, Naomi le advierte del peligro en el que se encuentra Sam y más tarde salva a Sam y a Dean de Crowley, ahuyentando al demonio y ayudando a los Winchester a completar la segunda prueba para sellar el Infierno al permitir que el alma atrapada de Bobby ascienda al Cielo. Ella reitera que Dean puede confiar en ella y que todos comparten el objetivo de sellar el Infierno. ^{[ 18 ]} Naomi y sus ángeles finalmente masacran a los clientes de un restaurante por el que saben que Castiel está pasando y dejan a uno con vida, traumatizado para que se detenga el tiempo suficiente para que puedan capturarlo; Naomi mata al superviviente después, rechazando el recordatorio airado de Castiel de que ellos (los ángeles) se supone que deben proteger a los humanos. Ella interroga a Castiel sobre la ubicación de la tableta y revela que ha estado alterando y borrando sus recuerdos durante más tiempo del que se sabe, quejándose de que nunca ha funcionado como se suponía que debía hacerlo. Huye cuando Crowley ataca a sus hombres y le dispara con un arma cargada con espadas de ángel fundidas. ^{[ 13 ]} En el final de la temporada 8, Naomi descubre que Metatron está trabajando con Castiel, lo que la impulsa a capturar al ángel renegado y usar su instrumento parecido a un taladro para acceder a sus pensamientos y conocer sus planes; cuando descubre cuáles son, se horroriza e inmediatamente advierte a Dean y Castiel, revelando que Metatron no está tratando de cerrar las puertas del Cielo, sino que está tratando de expulsar permanentemente a todos los ángeles en venganza por haber tenido que huir para escapar de ella y los arcángeles, quienes le habían ordenado que lo detuviera y tomara el conocimiento que tenía como Escriba de Dios después de que Dios abandonara el Cielo. Naomi expresa remordimiento por sus acciones y las de los otros ángeles, diciendo que los ángeles están destinados a proteger a la humanidad. Para empezar a enmendar sus errores, advierte a Dean que si Sam completa las pruebas, morirá, y luego se ofrece a escuchar a Castiel si realmente desea regresar al Cielo. Como no pueden confirmar sus afirmaciones, Castiel se niega a creerle, aunque Dean sí lo hace y finalmente impide que Sam complete las pruebas. Más tarde, encuentran a Naomi desplomada sobre su escritorio en su "oficina" en el Cielo. Metatrón se había liberado y la apuñaló en la cabeza con su propio taladro fuera de cámara. Metatrón se burla de Castiel diciéndole que ella había estado diciendo la verdad, y luego completa su plan. ^{[ 19 ]} Se confirma la muerte de Naomi mediante un diálogo en el episodio "No soy un ángel" de la temporada 9. ^{[ 20 ]}

En el episodio "Funeralia" de la temporada 13, Castiel regresa al Cielo para pedir ayuda a los ángeles para encontrar a Gabriel, quien aún vive, y luchar contra el invasor Miguel Alternativo. Allí encuentra a Naomi con vida. Naomi explica que sobrevivió al ataque de Metatrón, pero sus heridas fueron tan graves que hizo correr la voz de que había muerto. Incluso después de casi cinco años para recomponer sus pensamientos, Naomi sigue estando "casi intacta". Sin embargo, su presencia es necesaria, ya que menos de una docena de ángeles siguen vivos, incluyendo a Naomi y Castiel. Con una personalidad muy diferente, Naomi le explica a Castiel que los ángeles supervivientes pronto se consumirán y el Cielo se derrumbará si algo no cambia. Por lo tanto, los ángeles no pueden abandonar el Cielo sin arriesgarse a que esto suceda. La única esperanza de los ángeles es que Gabriel regrese, ya que su poder puede estabilizar el Cielo. Si no lo encuentran, cuando el Cielo se derrumbe, todas las almas serán liberadas en la Tierra como fantasmas. Ahora aliados, Naomi acompaña a Castiel a la Tierra y le promete que los ángeles restantes mantendrán el Cielo en funcionamiento el mayor tiempo posible si él no encuentra a Gabriel, aunque expresa su creencia de que tal vez la situación no tenga solución. Al regresar al Cielo, Naomi sella el portal tras de sí hasta que la situación se resuelva.

Durante el episodio "Byzantium" de la temporada 14, ella aparece de nuevo donde se encuentra con Castiel y Dumah en el Cielo de Jack después de que este muere y asciende. Le explica a Castiel que Jack se fue y una amenaza está invadiendo el Cielo mientras derrota a los ángeles. Naomi detalla que se trata de La Sombra (la entidad que gobierna el Vacío) y revela que conoce a Castiel por haberse encontrado con ella, ya que él es el único ángel que ha escapado del reino. Naomi afirma que La Sombra quiere a Jack porque cree que pertenece a su dominio. Había considerado ceder a sus demandas, ya que de lo contrario el Cielo se derrumbaría. Cuando Castiel se negó, ella intentó suplicarle a su hermano, pero La Sombra la poseyó y les imploró a sus hermanos que huyeran. Más tarde, Naomi se encuentra de nuevo con Castiel después de que este hiciera un trato con La Sombra y se marchara. Se la ve ilesa del ataque y le agradece su papel, aunque no lo haya hecho por el Cielo. Como recompensa, le revela a Castiel la ubicación de Michael Alternativo.

En "Ausencia", Castiel intenta contactar a Naomi, pero en su lugar se encuentra con Dumah, quien afirma que Naomi no está disponible. En "Jack en la Caja", Castiel regresa al Cielo, donde Dumah revela que derrocó a Naomi tras la invasión de la Sombra y la encerró en una pequeña celda. Dumah comienza a manipular a Jack para consolidar su poder e instaurar un reinado de terror, pero Castiel la mata cuando amenaza el Cielo compartido de John y Mary Winchester. Tras la muerte de Dumah y la ascensión de Jack al trono, no queda claro si Naomi fue liberada de su mazmorra.

Rafael es el arcángel encargado de proteger a Chuck Shurley. Rafael aparece para proteger a Chuck en dos ocasiones: en "El monstruo al final del libro", cuando está en presencia de Lilith, y en "Lucifer Rising", donde mata a Castiel mientras él y Dean intentan impedir el ascenso de Lucifer. Es invocado y posteriormente atrapado por Dean y un Castiel resucitado en el episodio de la quinta temporada "Libres para ser tú y yo", pero se niega a cooperar cuando le exigen saber la ubicación de Dios, limitándose a decir que cree que Dios está muerto. Dean y Castiel dejan a Rafael atrapado a pesar de su amenaza de dar caza a Castiel cuando escape. En este episodio, Rafael aparece por primera vez en un cuerpo físico y es interpretado por el actor Demore Barnes , quien retoma el papel en "El tercer hombre" y "El hombre que pudo reinar". Tras evitar el Apocalipsis, Rafael y sus seguidores están en guerra con Castiel y sus seguidores debido a la oposición de Castiel al plan de Rafael de liberar a Lucifer y Miguel para reiniciar el Apocalipsis. Su segunda aparición en pantalla es en el episodio "El tercer hombre" de la sexta temporada, donde él y sus soldados persiguen a Castiel. Rafael domina a Castiel y está a punto de matarlo cuando Balthazar interviene y destruye irrevocablemente el cuerpo de Rafael con una de las armas del Cielo, salvando así la vida de Castiel. Rafael se ve obligado a buscar un nuevo cuerpo, y finalmente posee a una mujer interpretada por Lanette Ware. En "El error francés", envía al ángel sicario Virgilio tras los aliados de Castiel, incluidos los Winchester. Balthazar transporta a los hermanos a un universo alternativo con una llave del lugar donde se almacenan las armas del Cielo, y Virgilio los sigue. Se revela que esto fue una estratagema de Balthazar y Castiel, dándole tiempo a este último para recuperar las armas. Ahora equipado con las armas, Castiel obliga a Raphael a huir cuando este último está a punto de matar a Sam y Dean, quienes han regresado. Los flashbacks en "El hombre que pudo reinar" muestran el trasfondo de la guerra de Raphael con Castiel; Raphael creía que el Apocalipsis estaba destinado a ocurrir e informó a Castiel de su intención de liberar a Lucifer y Michael de la jaula, dándole a Castiel el ultimátum de someterse o morir. Habiendo forjado un trato con el demonio Crowley, Castiel atacó a Raphael y declaró la guerra en el Cielo. En el final de la sexta temporada, "El hombre que sabía demasiado", Castiel incumple su trato con Crowley, quien recurre a Raphael. Crowley acepta abrir el Purgatorio para Raphael a cambio de su seguridad. Sin embargo, su ritual falla mientras Castiel abre el Purgatorio para sí mismo. Castiel aparece, ahora más poderoso que nunca, y aniquila a Raphael con un chasquido de dedos. En "Nosotros, los pocos felices", cuando discuten cómo derrotarán a la Oscuridad,Dios les dice a los Winchester que no puede resucitar a Rafael ni a Gabriel, ya que son seres de creación primordial y tardaría demasiado tiempo en volver a la vida.

Tessa is a reaper who guides the souls of the deceased to the afterlife (see also Psychopomp). She is portrayed by Lindsey McKeon. Following the car accident in the first-season finale, Dean is critically wounded, and his soul leaves his body. Dean attempts to save other souls and defends himself from a reaper. The reaper then returns in the form of Tessa, posing as a coma patient. She attempts to convince Dean to move on but, as he considers this, Azazel intervenes as part of his deal with John Winchester and possesses Tessa to restore Dean to life, although Dean remembers none of this. In the Season 4 episode "Death Takes a Holiday", she continues the work of a local reaper who has gone missing. After restoring Dean's memories of her with a kiss, she assists the brothers and agrees not to reap the souls for the duration. She is kidnapped by Alastair as part of a ritual to unlock a seal, but Dean and Sam rescue her. After getting Dean to help her have a young boy named Cole move on from being a ghost, she warns Dean that the angels are not looking for his best interest and to trust his own instincts.^[21] In "Appointment in Samarra", Dean summons Tessa during an out-of-body experience and asks her to call Death. Although she refuses, Death arrives on his own accord. Subsequently, Tessa guides Dean in his role as Death for 24 hours as part of a wager made with the Horseman in order to retrieve Sam's soul. Tessa returns in "Stairway to Heaven" where she is a part of Castiel's faction to retake Heaven. She has grown depressed over the fact that she can no longer ferry souls to Heaven due to it being closed and that she can hear their cries for help and is brainwashed by Metatron into acting as a suicide bomber for him, supposedly under Castiel's instruction in order to unite all the angels under his command. Tessa is found and captured by Dean before she can do this and her "bomb" is defused. Dean questions Tessa who, under her brainwashing, insists she is doing it for Castiel. When Dean pulls the First Blade on her, Tessa commits suicide by impaling herself on the Blade while Dean is holding it, thanking him at the same time. Her method of suicide makes it appear that Dean murdered her and helps turn Castiel's followers against him.

Interpretada principalmente por la actriz Alaina Huffman , Abaddon es la última Caballero del Infierno, una clase de poderosos demonios que fueron de los primeros de su especie. Abaddon es demasiado fuerte para ser afectada por exorcismos o asesinada por el cuchillo de Ruby . Se la presenta en el episodio de la octava temporada "As Time Goes By", en el que es enviada a destruir la organización de los Hombres de Letras en 1958 y parte en busca del abuelo de Sam y Dean, Henry Winchester, quien escapó con la llave del búnker de los Hombres de Letras. Deseando entrar al búnker para obtener acceso a los poderosos hechizos y artefactos sobrenaturales que contiene, Abaddon sigue a Henry a través del tiempo hasta el presente y lo persigue a él y a sus nietos durante todo el episodio. Como resultado, toma a Sam como rehén para obligar a Dean a entregar a Henry y la llave, prometiendo dejarlos ir después del intercambio. Abaddon incumple su acuerdo y termina hiriendo mortalmente a Henry, pero no sin antes que él le dispare en la cabeza con una bala grabada con una trampa para demonios, vinculando sus poderes y a ella a su cuerpo huésped ahora paralizado. Sam y Dean la descuartizan y la entierran en cemento para sepultarla para siempre. En "Clip Show", Sam y Dean necesitan un demonio para curar para la tercera prueba para cerrar las puertas del Infierno, así que vuelven a coser a Abaddon para usarla, sin volver a unirle las manos ni extraer la bala. Abaddon revela que había sido enviada para matar al sacerdote que encontró una forma de curar demonios, y que mientras lo torturaba, se enteró por él de los Hombres de Letras (incluida su huésped Josie Sands). Esto finalmente resultó en que poseyera a Josie y atacara a los Hombres de Letras. Mientras Sam y Dean reciben una llamada de Crowley afuera, Abaddon se libera y escapa controlando una de sus manos amputadas y usándola para extraer la bala de su cráneo. En el siguiente episodio, el final de temporada titulado "Sacrificio", ella llega en respuesta a la llamada de auxilio de Crowley, pero lo ataca en lugar de ayudarlo. Abaddon declara su intención de apoderarse del Infierno, pero Sam la ahuyenta prendiéndole fuego sagrado.

Abaddon regresa en la novena temporada, con el objetivo de matar a Crowley, convertirse en la Reina del Infierno y "convertir a toda la humanidad en su ejército demoníaco". ^{[ 31 ]} Con Crowley prácticamente ausente del Infierno y profundamente afectado por la cura demoníaca incompleta que le impusieron los Winchester, la intimidante Abaddon termina ganándose el apoyo casi unánime de los demás demonios. En "First Born", Crowley y Dean acuden a su creador, maestro y antiguo amante, Caín, para obtener su Marca . La Marca de Caín permite empuñar la Primera Espada, la única arma capaz de matar a Abaddon. Caín revela que Abaddon, tras fracasar en su intento de convencerlo de que volviera con ella, lo engañó para que asesinara a su amada esposa humana, Colette. Le hizo una promesa a Colette, lo que le impide buscar venganza directamente, así que le da la Marca a Dean para que este pueda matar a Abaddon una vez que Crowley encuentre la Espada.

El episodio "La pequeña ayudante de mamá" revela que la relación de Abaddon con los Hombres de Letras se remonta a mucho antes de lo que se creía. Abaddon había sido confrontada por Henry y Josie mientras robaba almas en un convento, antes de la masacre de los Hombres de Letras. Su intención era poseer a Henry para espiar a los Hombres de Letras antes de destruirlos, pero aceptó la oferta de Josie y la poseyó a ella, todo sin que Henry lo supiera.

En el presente, Abaddon ordena a sus secuaces que vuelvan a robar almas para formar un ejército de demonios leales. Para eliminar cualquier amenaza a su reinado, Abaddon urde un plan para asesinar a Crowley y a los Winchester, y destruir la Primera Espada. Trae al hijo humano de Crowley, Gavin, al futuro y lo tortura hasta que Crowley accede a ayudarla a tender una trampa a Sam y Dean. Con la intención de destruirlos a todos a la vez, Abaddon envía a Crowley con los Winchester para recuperar la Primera Espada y luego guiarlos hasta ella. Crowley logra engañar a Abaddon y advertir a Dean de la trampa, pero él no puede detenerla. Abaddon termina disparándole a Crowley con una bala de trampa demoníaca, impidiéndole intervenir en la batalla. Antes de que pueda llevar a cabo el resto de su plan y matar a Crowley, Gavin y los Winchester, Dean la mata empuñando la Primera Espada. Tras la muerte de Abaddon, la mayoría de los demonios volvieron a seguir a Crowley. Aquellos que permanecieron leales a Abaddon intentaron emboscar a Dean tras la muerte de su líder en "Black", pero fueron aniquilados fácilmente.

El productor ejecutivo y guionista de la serie, Adam Glass, reveló en Twitter que Abaddon se inspiró en Lauren Bacall , una actriz a la que admira. ^{[ 32 ]} El showrunner Jeremy Carver profundizó en la motivación del personaje, explicando que Abaddon estaba "horrorizada" al descubrir que Crowley gobernaba el Infierno porque "ama el Infierno y lo que representa". Creía que los contrastes en las visiones de ambos personajes generaban "un buen conflicto en nuestro mundo demoníaco". ^{[ 31 ]}

Abraxas, interpretado por Nelson Leis en la temporada 14 , es el poderoso y sádico demonio de ojos negros que asesinó a la familia de Nick , el futuro recipiente de Lucifer .

Abraxas es mencionado brevemente, aunque no por su nombre, en el episodio " Sympathy for the Devil " de la quinta temporada, cuando Lucifer menciona los brutales asesinatos de la familia de Nick para manipularlo y lograr que consienta en la posesión.

En el episodio "Dioses y monstruos" de la temporada 14 , Nick descubre que los asesinatos de su familia siguen sin resolverse después de nueve años y busca venganza, comenzando con Arty Nielson, su vecino que presenció a un hombre salir corriendo de la casa de Nick la noche de los asesinatos. En "Naturaleza inhumana", Nick localiza a Frank Kellogg, el policía poseído por Abraxas la noche de los asesinatos. Frank le cuenta a Nick que su esposa, Sarah, había llamado a la policía para denunciar a un intruso, y que cuando Frank investigó, encontró a Abraxas afuera. Tras presentarse, Abraxas poseyó a Frank y golpeó brutalmente a Sarah y al hijo de Nick, Teddy, hasta matarlos con un martillo . Nick recuerda que Lucifer conocía el nombre de Abraxas y se da cuenta de que un demonio mató a su familia, pero aun así asesina a Frank.

En "Mercancías Dañadas", Nick captura, tortura y asesina demonios en busca de Abraxas. Finalmente, captura a un demonio que colaboró ​​con Abraxas para matar a casi toda una tropa de Girl Scouts . El demonio revela que Abraxas fue capturado por Mary Winchester, la madre de Sam y Dean Winchester. Tras recibir la información, Nick mata al demonio y va en busca de Mary. Nick la secuestra y la obliga a confesar que, al no poder derrotar a Abraxas, lo encerró en una caja de rompecabezas enoquiana. Nick obliga a Mary a guiarlo hasta el almacén donde se encuentra la caja de rompecabezas y secuestra a un guardia de seguridad llamado Jeff para que actúe como recipiente de Abraxas. Mientras posee a Jeff, Abraxas queda atrapado en una trampa para demonios. Abraxas se ofrece a decirle a Nick lo que quiere saber si Nick asesina a Mary. Los Winchester y la sheriff Donna Hanscum interrumpen, lo que provoca que Nick rompa la trampa para demonios y libere a Abraxas. Abraxas le revela a Nick que Lucifer le ordenó cometer los asesinatos y que él lo eligió lanzando un dardo a la guía telefónica. Dean intenta un exorcismo , pero Abraxas lo detiene. Mientras Abraxas está distraído, Nick se acerca por detrás y lo mata con una espada angelical.

Mencionado por primera vez en el episodio "Atrapado en el medio (contigo)" de la temporada 12 , Asmodeo es un demonio y uno de los cuatro Príncipes del Infierno, junto con Azazel , Ramiel y Dagón . Al igual que Ramiel y Dagón, se dice que Asmodeo abandonó el Infierno hace mucho tiempo, tras haber perdido interés en los planes de Lucifer para dedicarse a sus "aficiones". Tanto Lucifer como Gabriel lo describen como el más débil de los Príncipes del Infierno. Lucifer también insinúa que Asmodeo es el más joven de ellos.

Asmodeo (interpretado principalmente por Jeffrey Vincent Parise ) aparece por primera vez en el episodio "El hijo naciente" de la temporada 13. En el antiguo palacio de Crowley , Asmodeo se proclama nuevo Rey del Infierno ante todos los demonios reunidos, con la intención declarada de gobernar hasta que Lucifer o su hijo nefilim, Jack, sean encontrados para reemplazarlo. Haciendo gala de un poder inmenso, Asmodeo comienza rápidamente a remodelar el Infierno según sus estándares, ejecutando sumariamente a varios demonios que no los cumplen. Asmodeo usa su capacidad de cambiar de forma para acercarse a los Winchester y a Jack. Disfrazado como el profeta Donatello Redfield, Asmodeo manipula a Jack para que abra un portal y libere a los Shedim, criaturas a las que incluso Lucifer teme. Tras ser descubierto, Asmodeo se ve obligado a retirarse ante la furia de Jack.

En "La guerra de los mundos", Asmodeo usa sus poderes para buscar a Jack mientras interroga a quienes han visto a los Winchester. Asmodeo presiente el regreso de Lucifer del Mundo del Apocalipsis y encuentra a Lucifer y Castiel juntos en un bar. Al reconocer el estado debilitado de su "padre", Asmodeo anuncia su intención de conservar el poder en el Infierno y encarcela a Lucifer y Castiel. Luego contrata a Arthur Ketch, un antiguo miembro de los Hombres de Letras británicos y un hábil asesino, para que lo ayude a buscar a Jack. Para evitar que los Winchester descubran que Castiel ha sido capturado, Asmodeo se hace pasar por Castiel en una llamada telefónica para engañarlos. Asmodeo se comunica con los Winchester de esta manera durante algunos episodios para despistarlos y averiguar si han descubierto algo sobre el paradero de Jack. Lucifer y Castiel logran escapar más tarde en "Varios villanos" mientras Asmodeo está ausente.

En «El escorpión y la rana», Asmodeo descubre los planes del demonio de la encrucijada, Barthamus, de atacar la casa de Luther Shrike y recuperar el baúl que contiene sus huesos humanos. Deseando deshacerse del traidor, Asmodeo envía un mensajero demoníaco para advertir a Luther y pedirle que le avise si Barthamus llega. Luther se niega a ayudar a Asmodeo y, en cambio, exorciza al mensajero.

En "El pacto del diablo", Asmodeo intenta que Arthur Ketch localice y mate al debilitado Lucifer. Al mismo tiempo, interroga al profeta Donatello Redfield, descubriendo el plan de los Winchester para abrir la puerta al Mundo del Apocalipsis. Asmodeo pone a Donatello bajo su control, convirtiéndolo en un espía involuntario. Tras el fracaso de Arthur en su intento de matar a Lucifer, Asmodeo revela su última adquisición: la Espada del Arcángel, la única arma capaz de acabar con él. Arthur señala que solo un arcángel puede empuñarla, lo que lleva a Asmodeo a presentar al arcángel Gabriel, a quien se creía muerto desde hace casi ocho años. Se revela que Gabriel es prisionero de Asmodeo.

En "La Cosa", Arthur descubre a Asmodeo inyectándose la gracia de Gabriel. Asmodeo ignora a Arthur hasta que esté listo para verlo y se muestra muy disgustado al saber que Arthur sabía que Castiel estaba en Siria buscando el Árbol de la Vida. Enfurecido por las recientes acciones de Arthur, Asmodeo lo golpea brutalmente, afirmando que Arthur es peor que cualquier demonio que conozca y que le pertenece por su naturaleza, a pesar del deseo de redención de Arthur. La paliza de Asmodeo provoca que Arthur libere a Gabriel y robe la Espada del Arcángel y la reserva de la gracia extraída de Gabriel que Asmodeo guardaba, llevando los tres objetos a los Winchester.

En "Bring 'em Back Alive", Gabriel les cuenta a Sam y Castiel que, tras fingir su muerte, fue capturado y vendido a Asmodeo, quien lo torturó durante años y usó su gracia para obtener poderes. Mientras Sam y Castiel intentan tratar al traumatizado Gabriel, Asmodeo usa sus poderes para localizarlo, encontrándolo finalmente en el búnker de los Winchester. Asmodeo llama a Sam y amenaza con destruir el búnker si no le entregan a Gabriel en diez minutos. Cuando Sam se niega, Asmodeo rompe las protecciones y lidera una incursión demoníaca para matar a Sam y Castiel y recapturar a Gabriel. Aunque la incursión tiene éxito inicialmente, cuando Asmodeo comienza a torturar a Sam y Castiel, provoca que Gabriel recupere la cordura y se defienda. Asmodeo demuestra ser inferior al arcángel enfurecido, quien lo incinera en represalia por todo lo que el Príncipe del Infierno le hizo.

En "Asuntos Pendientes", los Winchester se encuentran con Gabriel, quien busca venganza contra los dioses nórdicos Loki , Fenrir , Sleipnir y Narfi . Gabriel cree que los dioses lo traicionaron y lo vendieron a Asmodeo para obtener ganancias antes de que Lucifer descubriera que seguía vivo. Gabriel revela que Asmodeo lo torturó diariamente durante años y que permanece debilitado, ya que Asmodeo le arrebató gran parte de su gracia. Gabriel señala que su gracia no ha tenido tiempo de recuperarse mucho después de usarla para matar al Príncipe del Infierno. Más tarde, Loki le confiesa a Dean que vendió a Gabriel a Asmodeo porque lo culpaba de la muerte de su padre, Odín, a manos de Lucifer.

Belphegor, interpretado por Alexander Calvert , es un demonio liberado del Infierno cuando Dios inicia el Apocalipsis y se alía con los Winchester. Aunque es un demonio de bajo rango, se desconoce el color real de sus ojos, ya que los de su huésped se queman mientras Belphegor lo posee. Belphegor solo afirma no ser un simple demonio de ojos negros ni un Demonio de la Encrucijada. También se sabe que trabajó como torturador en el Infierno.

En "Regreso al futuro", Belphegor, poseyendo el cadáver de Jack, el hijo Nephilim de Lucifer, se presenta como aliado de los Winchester. Explica que en el Infierno tortura almas y disfruta de su trabajo, por lo que desea restaurar el Infierno a la normalidad. Aunque reacios, los Winchester y Castiel aceptan aliarse con Belphegor, quien promete abandonar el cuerpo de Jack en cuanto encuentre un nuevo recipiente adecuado. Belphegor ayuda a los tres a escapar de la horda de zombis que los tiene atrapados y les ofrece un hechizo para confinar las almas liberadas en un radio de una milla alrededor del cementerio donde fueron liberadas. Trabajando con Dean, Belphegor lanza el hechizo con éxito y contiene a los fantasmas. Sin embargo, le revela a Dean que todas las puertas del Infierno se abrieron, lo que significa que entre dos y tres mil millones de fantasmas andan sueltos y, además, la Jaula de Lucifer se abrió, liberando potencialmente a Michael para sembrar el caos. En "Desatando el infierno", Belphegor sigue ayudando a los Winchester, Castiel y Rowena en sus esfuerzos por contener a los fantasmas fugados y la barrera debilitada. Al mismo tiempo, Arthur Ketch revela que ha sido contratado por el demonio Ardat para asesinar a Belphegor, a quien ella describe como "una monstruosa amenaza para la humanidad".

En "La Ruptura", después de que el Libro de los Condenados no logra reparar la barrera, Belphegor ofrece una solución: el Báculo de Lilith, un cuerno creado por Lilith para atraer a los demonios y almas del Infierno de vuelta a ella en caso de que alguna vez escaparan de su control. Mientras Belphegor y Castiel viajan al Infierno para obtener el báculo, Sam y Rowena realizarán un hechizo para sellar la ruptura. Aunque Belphegor afirma que solo necesita a Castiel como apoyo, Castiel sigue sospechando de sus motivos, especialmente al descubrir que el báculo está en un cofre sellado en enoquiano que solo Castiel puede leer. Los dos son atacados por Ardat, quien revela que el verdadero motivo de Belphegor siempre ha sido tomar el poder en el Infierno para sí mismo y está usando a los Winchester y a Castiel para ese propósito. Belphegor mata a Ardat y confirma que decía la verdad, con la intención de usar el báculo para atraer a todos los demonios y almas dentro de sí mismo y obtener poder ilimitado. Cuando Belphegor usa el cuerno, Castiel lo golpea y lo derriba. Belphegor intenta hacerse pasar por Jack para que Castiel lo detenga. Al descubrir el engaño, Castiel ataca a Belphegor sin dudarlo, matando al demonio y acabando con el ladrón, pero a costa de reducir el cuerpo de Jack a un esqueleto carbonizado. Tras enterarse de la muerte de Belphegor, Dean se enfada con Castiel, pues cree que el demonio era una amenaza que podrían haber neutralizado más adelante. La muerte de Belphegor antes de que pudieran completar el plan obligó a Rowena a sacrificarse para enviar las almas restantes de vuelta al Infierno. Las acciones de Castiel con Belphegor, así como el hecho de que ocultara el estado sin alma de Jack, crean una brecha entre ambos durante un tiempo.

Caín (interpretado por Timothy Omundson ) fue el primogénito de Adán y Eva que asesinó a su hermano Abel . Si bien todos creían que Caín había matado a Abel porque estaba hablando con Dios , en realidad lo hizo porque estaba hablando con Lucifer. Amando a su hermano, Caín hizo un pacto con Lucifer: el alma de Abel en el Cielo a cambio de convertirse en el primer Caballero del Infierno portando la Marca de Caín . Sin embargo, como parte del trato, Caín tuvo que matar a Abel personalmente. Después, arrepentido de sus actos, Caín se suicidó, pero la Marca lo resucitó como un poderoso demonio. Durante miles de años, Caín fue el peor de los peores, ganándose el título de Padre del Asesinato y entrenando al resto de los Caballeros del Infierno. Finalmente, Caín se enamoró de una mujer humana, Colette, y abandonó su maldad por ella, suprimiendo la influencia de la Marca sobre él para seguir masacrando gente. En 1863, los demás Caballeros secuestraron a Colette para obligar a Caín a retomar sus viejas andanzas. Caín masacró a todos los Caballeros, pero cuando llegó a Abaddon, ella poseyó a Colette y lo engañó para que matara a su esposa. Debido a la última voluntad de Colette, Caín no persiguió a Abaddon en busca de venganza y arrojó la Primera Espada al fondo de la Fosa de las Marianas, ya que era indestructible, y finalmente se estableció en Misuri . En First Born , mientras buscaban la Primera Espada para matar a Abaddon, Dean y Crowley localizaron a Caín y le pidieron la Primera Espada. Caín no estaba interesado en ayudarlos, pues quería cumplir su promesa a Colette, pero observó cómo Dean luchaba y mataba a tres demonios él solo. Impresionado, Caín les contó su historia a Dean y Crowley, pero al principio se negó a ayudarlos. Finalmente, después de hablar con la tumba de Colette, Caín decidió ayudarlo dándole a Dean la Marca de Caín para que pudiera empuñar la Primera Espada y matar a Abaddon. A cambio, le pidió a Dean que lo matara después, antes de enviar a Dean y Crowley lejos y enfrentarse solo al ejército de Abaddon. En La canción del verdugo , se revela que matar a los demonios de Abaddon provocó que Caín volviera a caer bajo la influencia de la Marca de Caín. Cediendo a su furia, Caín decidió que, dado que muchos de sus descendientes eran asesinos y otros tipos de criminales, exterminaría a su linaje, a pesar de ser "legión". Caín mató a mucha gente, y finalmente fue descubierto por Sam y Dean cuando secuestró a un asesino en serie.Tommy Tolliver. Caín se enfrentó a Castiel en el lugar de las tumbas de sus víctimas, pero lo dejó ir para que Castiel le dijera a Dean quién traería la Primera Espada para matarlo. Al ir tras el hijo de Tommy, Austin, Caín fue atraído a una trampa del diablo por Dean, Sam, Castiel y Crowley, tras lo cual Dean lo enfrentó solo. Caín le afirmó a Dean que no había cura para la Marca de Caín y que era mejor ceder a su furia. Dean y Caín lucharon, pero Caín demostró ser más poderoso y derrotó fácilmente a Dean, obteniendo finalmente la Primera Espada para sí mismo. Antes de que pudiera matar a Dean, este logró tomar el cuchillo de Caín y cortarle la mano. Caín se negó a dejar de matar, obligando a Dean a matarlo. Si bien Dean conservó su humanidad, el descenso de Caín a la locura los dejó a él y a Sam profundamente preocupados.

Un demonio específico de las encrucijadas reapareció a lo largo de la segunda y tercera temporada de la serie, poseyendo únicamente a mujeres jóvenes y hermosas. Las actrices Christie Laing y Jeannette Sousa la interpretan por primera vez en "Crossroad Blues". Laing interpreta al demonio en flashbacks que muestran al músico Robert Johnson vendiendo su alma para aprender a tocar la guitarra, mientras que Sousa lo interpreta en el presente. Esta última es invocada por Dean en un intento de rescatar a un hombre de un pacto demoníaco previamente hecho. Rechaza la súplica de Dean y, en cambio, se burla de él por el sufrimiento de su padre en el infierno. Dean la engaña para que caiga en una trampa del diablo y la libera a cambio de liberar al hombre de su contrato. ^{[ 33 ]} El demonio regresa de nuevo en el final de la segunda temporada, " All Hell Breaks Loose ", ahora en posesión de una mujer interpretada por Ona Grauer . Ella resucita a Sam a cambio de recoger el alma de Dean en un año. ^{[ 34 ]}

Su última aparición es en "Cuentos para dormir", interpretada ahora por Sandra McCoy . Al final del episodio, Sam la llama y le exige que rompa su trato con Dean a cambio de su vida. Ella afirma no tener el contrato, siendo solo una empleada con un jefe al que rendir cuentas. Un Sam frustrado mata al demonio con la mística pistola Colt. ^{[ 35 ]} En ese momento, McCoy salía con el actor principal Jared Padalecki después de haber trabajado con él en la película de 2005 Cry Wolf .

Dagon (portrayed by Ali Ahn) is one of the four Princes of Hell and one of the oldest and most powerful demons in existence. Despite being female (or in a female host), Dagon is still referred to as a Prince of Hell rather than a Princess. Like her brothers Ramiel and Asmodeus, Dagon long ago lost interest in Lucifer's plans and left Hell for a life on Earth. She is implied to have failed Lucifer in some way at some point.

She is first mentioned in a flashback in "Stuck in the Middle (With You)", when Ramiel tells Crowley that Dagon has her "toys" and is uninterested in ruling Hell. Later, Ramiel tells the Winchesters that Dagon has taken an interest in Lucifer's unborn Nephilim child, though Ramiel himself couldn't care less.

Dagon is first introduced in person in "Family Feud", when she kills two angels to save the life of Kelly Kline, the mother of Lucifer's unborn child. In "Somewhere Between Heaven and Hell", Castiel learns of Dagon's involvement and warns the Winchesters about her, stating that all he knows of Dagon is rumors of her psychotic savagery.

Dagon continues her role as protector of Lucifer's child in "The British Invasion". She is revealed to secretly be working for Lucifer who has promised Dagon a place at his side if she succeeds and is often in telepathic communication with the Fallen archangel. To cover her tracks, Dagon has another demon murder everyone who meets Dagon and Kelly, including a doctor who did a fetal examination on Kelly's insistence. Dagon's activities are discovered by hunter Eileen Leahy, who helps lure Kelly out. Dagon shows up at the meeting and resists all attempts to kill her, including with the Colt. Dagon disappears with Kelly and reveals to the woman that the pregnancy will ultimately be fatal to her.

In "The Future", Dagon finds Kelly following her suicide and resurrection by Lucifer's child. While Kelly now believes the child to be good, Dagon believes that the child simply acted out of self-preservation. Dagon is later attacked by a team of angels led by Castiel who attempt to kill her with the Colt. Castiel escapes with Kelly, but Dagon kills one of the angels and tortures the other for information before killing him too. Dagon then intercepts Castiel at Heaven's portal, killing the angel Joshua and engaging Castiel in battle. Dagon proves to be stronger than the angel, easily beating him to a pulp. The intervention of the Winchesters leads only to Dagon breaking Dean's arm and effectively destroying the Colt. As Dagon goes to kill Castiel, Lucifer's child empowers the angel from the womb, enabling him to stop Dagon and render her powerless to Dagon's shock. With the help of Lucifer's child, Castiel incinerates Dagon, killing her as predicted in a premonition the child shared with Kelly. The child's aid against Dagon convinces Castiel of his goodness.

In the season 13 episode "Lost & Found", the newborn Jack, Lucifer's son, experiences a flashback to Dagon's death when asked what he remembers. Jack states that he remembers "when the bad woman burned".

Ramiel (portrayed by Jerry Trimble) is one of the four Princes of Hell in Supernatural alongside Azazel, Dagon and Asmodeus. As a Prince of Hell, Ramiel is one of the oldest and most powerful demons to ever live and a retired demonic general. Unlike Azazel, Ramiel has long-since lost interest in Lucifer's plans and separated himself from Hell, joined by Dagon and Asmodeus. During his time on Earth, Ramiel becomes a collector of rare supernatural artifacts and weapons.

In a flashback in "Stuck in the Middle (With You)", the demon Crowley meets with Ramiel in 2010 following the defeat of Lucifer and the end of the Apocalypse. With Lucifer locked up again and Lilith and Azazel dead, Ramiel is next in line to be the King of Hell. However, Ramiel is uninterested, continuing to have no interest in the affairs of Hell and calling Azazel a "fanatic". Instead, Ramiel suggests that Crowley take power, but warns that if anyone disturbs him, there will be severe consequences. Crowley accepts Ramiel's terms and presents him with two gifts: the Lance of Michael, a weapon designed by the archangel Michael to kill Lucifer slowly and the Colt, the legendary gun that had once been used to kill Ramiel's brother Azazel.

In the present day of the episode, hunter Mary Winchester is sent by the British Men of Letters to steal the Colt from Ramiel. The organization fails to inform Mary that Ramiel is a Prince of Hell, leaving the group of hunters she assembles woefully unprepared to fight the demon. Mary claims that Ramiel is simply a demon she is trying to eliminate that is doing evil actions while hiding her true purpose from the group. After a failed intervention by Crowley's demons, Mary succeeds in stealing the Colt before Ramiel returns from night fishing. Due to his sheer power as a Prince of Hell, Ramiel shrugs off all attempts to kill him and mortally wounds the angel Castiel with the Lance of Michael. Enraged by the theft of the Colt, Ramiel tracks the hunters to a barn and attacks Crowley when he attempts to intercede on the Winchesters' behalf. The Winchesters briefly trap Ramiel in Holy Fire and he demands the return of the Colt. When they fail to turn it over, Ramiel breaks free of the Holy Fire and attacks the hunters, once more shrugging off their attacks. After Ramiel nearly kills Dean, Sam steals the Lance of Michael from him with the help of a distraction by Mary and impales the Prince with the weapon. Designed to kill Lucifer, the Lance turns Ramiel to dust and is shortly thereafter destroyed by Crowley to save Castiel's life.

Samhain is a powerful whitish-eyed demon and the Origin of Halloween in season 4. Before he was imprisoned in Hell centuries ago, he reigned over Earth on Halloween night. People kept their children inside, they left treats to appease him and they left carved pumpkins on their doorsteps to worship him. His power seems to be intermediate between that of black-eyed demons and white-eyed demons. He maintains all traits and powers of a normal black-eyed demon, and he also proved capable of emanating a demonic energy blast similar to Lilith's.

Wanting to summon Samhain, two witches named Tracy Davis and Don Harding start performing the sacrifices needed to summon Samhain. This draws the attention of the Winchesters and the angels as the raising of Samhain is one of the 66 Seals. Sam and Dean kill Don, but Tracy reveals herself and successfully summons Samhain, breaking the seal. Samhain possesses Don's body and recognizes Tracy before killing her. Samhain is unable to tell that Sam and Dean are alive due to a "mask" of blood they smeared on their faces so he leaves them alone.

Samhain travels to a mausoleum where a bunch of high school students are having a party, locks them in and summons zombies and at least one ghost that attack. Sam and Dean rescue most of the kids and Dean deals with the monsters while Sam faces Samhain. Sam proves immune to Samhain's power so they fight hand to hand, but even with the demon-killing knife, Sam is no match for the demon. Finally, in the end, Sam manages to exorcise Samhain with his powers and sends him back to Hell.

A drawing of Samhain can be seen in Anna Milton's journal. The description says "Samhain. The next seal is broken." In Anna's drawing, Samhain's eyes are completely whitish, showing that Samhain is classified as a whitish eyed demon.

Asa Fox, portrayed by Shaine Jones as an adult and Jack Moore as a child is a legendary Canadian hunter appearing in Supernatural.

As shown in flashbacks in season 12's "Celebrating the Life of Asa Fox", in 1980, a twelve-year old Asa was attacked by a werewolf, an attack that left a lasting scar upon his face. Asa was saved by hunter Mary Winchester who had come out of retirement briefly to tie up some loose ends, including killing the werewolf and stopping its killing spree. Asa became interested in what Mary was doing, especially when she told him that she intended to return to retirement. Inspired by the encounter, Asa went on to become a hunter himself despite his mother's objections and became legendary in the hunting community. Asa wrote postcards throughout his life to Mary detailing his discoveries and hunts, but never sent them as he never learned her whereabouts. During his hunting trips, Asa had many trysts with local women, one of which, with witch Tasha Banes, resulted in two children, Max and Alicia. In 2016, Asa met Sheriff Jody Mills while on a ghoul hunt and, unaware that the sheriff was also a hunter, claimed that he was FBI agent Fox Mulder while investigating the case. Jody saw through his obvious disguise, helped him complete the hunt, and began a casual relationship with Asa whenever he was around. While Asa was not aware of it, Jody held him in high regard and harbored hopes that their relationship could become more serious.

In 1997, Asa came up against the sadistic Crossroads Demon Jael. Asa managed to exorcise the demon, but not before the demon brutally murdered the young girl he was possessing. After escaping from Hell again, Jael began a personal vendetta against Asa, murdering a woman that Asa was seeing as well as other people he cared about and leaving their bodies in the forest for him to find. In 2016, Asa hunted Jael through a forest with his best friend Bucky Sims despite Asa not being armed with his angel blade, leading to an argument between the two men. During the argument, Bucky shoved Asa who fell and hit his head on a rock and died. Bucky then framed Asa's death as his having been murdered by Jael.

While on a visit to Jody, Mary's children Sam and Dean learned of Asa's death and decided to accompany Jody to his funeral. While never meeting personally, Sam and Dean recalled hearing stories about him in Ellen's roadhouse, and Asa's peer hunters were quick to share stories of him killing five wendigos in one night. Dean expressed skepticism initially (due to hearing the story in the midst of a drinking game inspired by the exploit) but he later confided to Sam that he believed Asa to be a 'legit' hunter, evidenced by his armory, complete with an angel blade. During the funeral, they encountered their mother Mary who had recently been resurrected following her death in 1983. Mary had received word of Asa's death and was distressed to learn that he had become a hunter. Jael took advantage of the funeral to target the other hunters one by one, finally possessing Jody. In Jody's body, Jael confessed to feeling cheated out of Asa's murder and forced Bucky to admit that he had killed Asa. Before carrying out a brutal revenge against the hunters, Sam, Dean, Max, Alicia and Mary, exorcised Jael from Jody in a sequential attack, with each subsequent hunter picking up the Latin incantation where the previous one left off. As a result of Jael's efforts, Bucky was disgraced for killing his best friend. Rather than exacting revenge upon Bucky themselves, the hunters chose to spread the true story of what happened. The next morning, Asa was given a Hunter's Funeral alongside the two hunters murdered by Jael at his wake.

Charlie Bradbury (born Celeste Middleton) (played by Felicia Day) first crosses paths with Sam and Dean when working as an I.T. expert at Richard Roman Enterprises. She is initially reluctant to get involved in the supernatural world by helping the Winchesters, but becomes a more reliable ally in her second episode and decides to become a hunter herself by her fourth episode. She quickly becomes a friend and even a surrogate little sister to the Winchesters. By the end of "The Girl with the Dungeons and Dragons Tattoo", it is revealed that her real name is not Charlie Bradbury but merely one of her aliases, and that she has had to go into hiding before. "Pac-Man Fever" delves into her past and it is indicated that "Charlie's" true surname is Middleton. "There's No Place Like Home" reveals that Charlie's given name is in fact Celeste Middleton. She is the only prominent LGBT character on the show; in her first episode, she informs the brothers she is lesbian when she is asked to flirt with a male guard to gain access to a restricted area.

Charlie's first appearance is in the season seven episode "The Girl with the Dungeons and Dragons Tattoo", where Dick Roman asks her to decrypt Frank Devereaux's hard drive. Once she succeeds, she starts reading files describing the Leviathans and their activities, including their connection to Dick Roman. Although she doesn't believe it at first, she realizes the truth when she witnesses a leviathan eat her supervisor and shapeshift to replace him—something Dick explains they cannot do to Charlie, as she possesses a rare "spark" that can't be perfectly replicated. Sam and Dean recruit a terrified Charlie to retrieve Frank's hard drive to protect the information there, as well as to break into Dick's office and hack his emails to gain information for their side. She does so, which alerts Sam and Dean to a secret package meant for Dick which they then steal; the package is later revealed to hold the secret to defeating the leviathan. She is nearly killed when Dick realizes her duplicity, but is saved by Bobby's ghost holding the leviathan off—breaking Charlie's arm in the process—whilst Sam and Dean arrive and rescue her. She leaves after telling Sam and Dean not to contact her again.

Charlie reappears in the season eight episode "LARP and the Real Girl". Now under a different alias, Carrie Heinlein, she is the queen of one of four kingdoms of the LARPing game of Moondoor. When two of her "subjects" are killed, it draws Sam and Dean's attention and they head to Moondoor. Charlie's initial reaction is to flee and start a new life again, fearing that she will once more become a target for monsters. After learning why Sam and Dean are there, she agrees to help them investigate the deaths and other mysterious injuries that have happened. Charlie is eventually captured by a good fairy named Gilda who has kidnapped her on her master's orders. Charlie is instantly smitten with Gilda. Dean, Sam and Gerry eventually find Charlie with help from the "prisoner", only to find that she is making out with Gilda. It is revealed that Gerry is Gilda's master; he has unrequited feelings for Charlie and has bought a spellbook with which to control Gilda and force her to kill other players as part of a scheme to make Charlie fall in love with him. Charlie eventually destroys the book to set Gilda free and render Gerry powerless. Afterward, she and Gilda share a goodbye kiss before Gilda returns to her world with Gerry to have Gerry punished. Charlie decides to stop running and changing her identity and to stay and make a life for once. She tells Sam and Dean to call her if they ever need her help again. The three of them participate in a mock battle between their group and the other LARPers, which Charlie's side wins. Charlie's backstory is explored when she returns in "Pac-Man Fever" to give Sam and Dean a case. After she proves to be an excellent shot, Dean takes her as his (temporary) partner instead of Sam, who has become increasingly ill from the trials. Charlie is eventually captured by the creature they are hunting, a type of djinn, who poisons Charlie and places her in a nightmare from which she won't wake up from. In her nightmare, she is trapped in a video game she stole as a kid, recreated, and gave out for free, and where she must endlessly protect her hospitalized mother from super-soldier vampires. It is revealed that her parents had been involved in a car accident when driving over to pick Charlie up from a sleepover, resulting in her father dying and her mother rendered brain-dead. Charlie has been paying for the care of her mother, whom she refuses to let go due to her feelings of guilt over the accident. When Dean takes a potion to enter her nightmare himself to save her, he convinces Charlie that she must let her mother go to move on. She then wakes up and in the episode's last scene, takes Dean's advice by having her mother taken off of life-support after reading The Hobbit aloud to her like her mother did to Charlie as a little girl.

Charlie is called in by the Winchesters for help in the ninth-season episode "Slumber Party" to reconfigure an ancient computer at the Men of Letters' bunker. A childhood fan of L. Frank Baum's Oz books, Charlie is excited when the real Dorothy is found in the bunker. The group works together to try to find a way to defeat The Wicked Witch of the West. Charlie dies to protect Dean from the Witch, but he has Gadreel bring her back to life and tells her that she had only been knocked out, though she learns the truth anyway from Dorothy; Charlie later agrees to keep her death and subsequent resurrection a secret from Sam so long as Dean agrees to one day explain what had really happened. Charlie and Dorothy eventually devise a way to kill the Witch, but are attacked by Sam and Dean, who are both possessed by the Witch. While Dorothy holds the brothers off, Charlie finds and kills the Witch by stabbing in the head with Oz's famous ruby slippers before the Witch can let her army in through a portal to Oz. When Dorothy extends an offer to Charlie to come with her to Oz, Charlie jumps at the prospect of finally getting the kind of magic and adventure she wants. After bidding their goodbyes to the brothers, Charlie and Dorothy cross over to Oz, leaving Sam and Dean to speculate if and when they will come back.

In the season 10 episode "There's No Place Like Home", Sam and Dean find out that Charlie is back from Oz and is attacking people who helped cover up her parents deaths. To their surprise, they find there are two Charlie's, a good and a dark Charlie. The good Charlie explains that she and Dorothy fought a war in Oz to free it from evil and to win, Charlie made a deal with the Wizard of Oz to split herself into her good and dark sides. Charlie's dark side single-handedly won the war and Dorothy and the Wizard now lead Oz. Now, dark Charlie has come to Earth seeking revenge for her parents deaths, good Charlie following to stop her. As dark Charlie broke the Key to Oz so Charlie couldn't return, she and Sam investigate the Key in hopes of finding a way to fix it, and eventually track down a former Man of Letters named Clive Dylan who was trapped in Oz after discovering the Key. Dean meanwhile tries to protect Russell Wellington, the man who killed Charlie's parents, but Dark Charlie tricks Dean, kills Russell, and follows Dean to Clive's house where they fight and he brutally beats her, hurting Good Charlie who is still connected to her. At the same time, Sam and Charlie learn that the Wizard is in fact Clive's dark side, split from him as Charlie's was. Unable to fix the Key and to save Oz, Clive shoots himself to force the Wizard to Earth to heal Clive and save himself. Unable to defeat the Wizard, Clive signals Charlie to shoot him which she hesitantly does, killing Clive and the Wizard. Sam stops Dean from beating Dark Charlie to death and proceeds to reverse the Wizard's spell and reunite the two Charlies. Afterwards, Charlie, unable to return to Oz, decides to dedicate herself to finding a way to save Dean from the Mark of Cain and forgives his actions.

Charlie returns to the brothers several episodes later, having found an ancient book known as the Book of the Damned, which is said to document every curse as well as their cures. Upon acquiring the book, a group of unknown men, all with the same tattoo on their wrist, begin to pursue her. After a violent encounter with them, Charlie is shot but narrowly escapes, and calls the Winchesters from a telephone booth, informing them of her discovery and injury, mentioning she sewed it back together with dental floss, a testament to her resourcefulness. When reunited, Sam and Charlie begin their attempt to decipher the book's text, as it is written in an unknown ancient language, but Dean insists they stop, and destroy the book entirely, worrying that the Mark will cause him to use its information to do evil. Sam and Charlie decide not to destroy it but to put it away in a curse box, which will prevent anyone from tracking it down. Meanwhile, Dean goes to find Charlie's pursuers, who Sam had determined to be members of the historically prominent Styne family. When they attack the house Charlie and the Winchesters had been staying at, Dean instructs Sam to destroy the book before the men can take it. Sam throws the book in the fire, and the trio defeats and kills their attackers. However, it is later revealed he threw another book in, and hid the real book in hopes he could still cure Dean, despite his brother's wishes. When Charlie, Sam and Dean return to the bunker, they are greeted by Castiel, and Charlie is excited to meet him for the first time. Upon hugging him, she comments she had expected him to be shorter. At Charlie's joking request, Castiel heals her carpal tunnel and even her bullet wound without being asked, having gotten his full power back. The four then have a dinner, laughing and enjoying each other's company.

In "Dark Dynasty", Charlie is called in by Sam to work with Rowena on how to translate the Book of the Damned. Charlie is stunned that Sam lied about destroying the Book and reluctantly agrees to work on translating the Book behind Dean's back. However, Charlie is forced to work with Rowena who annoys her greatly with her disgust at Charlie being a nerd instead of a witch and her insistence that they are similar. Unable to take it anymore, Charlie asks Castiel to let her go cool off for a while and slips out while he ties up Rowena in another room. Going to a motel, Charlie continues her efforts to translate the Book of the Damned and finally manages to crack the code just before Eldon Styne arrives. Charlie contacts Sam and Dean, who tell her to give him the Book which she doesn't have, or her notes to save her life. However, unwilling to betray her friends or give the Styne Family the power of the Book, Charlie smashes her Surface and is killed by Eldon. A devastated Sam and Dean find her body soon afterwards. However, unknown to them, Charlie's last act was to email Sam her notes on how to translate the Book, giving them the chance to finish what she started.

In "The Prisoner", following her death, Sam and Dean cremate Charlie in hunter's tradition and Dean decides to slaughter the Stynes in revenge, telling Sam to stop the work on the Book. Sam initially does until he receives Charlie's email and decides to continue. Dean brutally slaughters the Styne family for what they did to Charlie and ultimately kills Eldon, avenging her.

Claire Novak, portrayed as a child by Sydney Imbeau and later in the series as a young adult by Kathryn Newton, is the daughter of Jimmy and Amelia Novak. She is raised in Pontiac, Illinois, until roughly the age of eleven, when her mother disappears, overwhelmed by grief of her father's death. Claire is then left in the custody of her grandmother until her death, at which point she is moved between numerous foster homes and eventually placed in a juvenile center.

Eight-year-old Claire is first introduced, along with her mother, in the season four episode "The Rapture", where the story of Jimmy becoming Castiel's vessel is revealed. Her first appearance occurs after Castiel is shown taking possession of Jimmy. Claire runs outside frantically and asks "Daddy?" to which Castiel replies that he is not her father, and begins to walk away, as she watches him leave. A year later when Castiel is forced out of Jimmy's body, Jimmy is able to return and begins to try and rebuild his life with his family. This is short lived, as demons learn about Jimmy, and take his wife and daughter hostage.

Claire is possessed by Castiel when her parents, Dean, and Sam Winchester, are held captive by demons, her mother having been possessed so that the demons could watch Jimmy and determine his unique qualities as a vessel. Castiel, in Claire's body, expels two demons from their hosts during the fight. Castiel intends to let Jimmy die so that he will go to Heaven and be at peace as a reward for his service, but Jimmy begs Castiel to use him as a vessel and free his daughter. Castiel obliges.

Seven years later, Castiel is inspired to look into Jimmy Novak's old life after recent events with Hannah. He discovers that Claire is in solitary confinement in a juvenile center after attempting the latest of a series of escapes, prompting him to visit and get her out by posing as Jimmy. Claire reveals that her mother vanished after leaving her with her grandmother, and she has been in and out of homes since her grandmother's death, blaming Castiel for breaking her family apart by taking her father as a vessel. Castiel helps her escape the center, but Claire steals his wallet and runs away again to rejoin with Dustin and Randy, friends of hers who were expecting her to collect money to help settle Randy's gambling debts.

The Winchesters and Castiel arrive in time to prevent the robbery, but Claire leaves them in disgust, declaring that Dustin and Randy are her family while the three men are just the people who killed her father. However, when Randy's loan shark offers to take Claire to compensate for the debt, Randy agrees, forcing the Winchesters and Castiel to step in and save her. They arrive at the house and are surprised to not see her, but when they hear screams coming from upstairs, they know she is in fact in the house, and in danger. Castiel locates her and busts down the door of the room where the loan shark is attempting to rape her.

Despite the Winchesters and Castiel saving her, Claire makes it clear that she still doesn't trust them, and resists Castiel's efforts to help her. After being brought to the bunker, she runs away, and meets a couple who suggest that she kill Dean as the person responsible for her father's death, helping them arrange a trap for him. However, she tips Dean off at the last minute, finding herself unable to go through with the plan, and he manages to fight them off and spare their lives despite the corrupting influence of the Mark of Cain. Although Claire still intends to leave Castiel and find a new life on her own, she suggests that she would not be against him keeping in touch with her.

Months later, in "Angel Heart", Claire is now eighteen and has begun searching for her long-missing mother, tracking her to Tulsa, Oklahoma. Claire confronts Ronnie Cartwright, the last person to see her mother and is knocked unconscious. As Castiel is in the emergency contacts on her cell phone, the hospital calls him and he calls in Sam and Dean to help him deal with her. After learning what she is up to, the Winchesters and Castiel decide to help her but she escapes the hospital and returns to her motel room where she finds Sam waiting for her while Dean and Castiel have gone to interrogate Ronnie. Sam offers to help Claire hack her mother's credit card records which she is intrigued by and with what they learn from that combined with what Castiel and Dean learn from Ronnie, they track Amelia to a farm run by a faith healer named Peter Holloway. However, Dean and Claire are left behind as they don't want Claire getting hurt and the Mark of Cain's influence on Dean is getting worse. While initially awkward for Dean and Claire, they bond over mini-golf and Claire inadvertently gives Dean a clue that they aren't dealing with a normal angel. Searching through the lore, Claire discovers that Holloway is a Grigori, a class of angel that preys on humanity. When they are unable to reach Sam and Castiel, Dean allows Claire to join him in the rescue, even giving her a gun. Claire and Dean find Castiel who has rescued a weak Amelia. Claire and her mother are finally reunited and Claire tearfully embraces her rather than berating her like she'd planned. While Claire tries to help Amelia out of the barn, Holloway, revealed to be Tamiel, comes and tells her that Amelia is beyond saving. Claire attempts to kill him with the gun and when she fails, he tries to kill her. Amelia sacrifices herself to save her daughter, leaving Claire devastated. Sam, Dean and Castiel are unable to defeat Tamiel so Claire kills him herself with his own sword to save them and avenge her mother. The next day, the three decide to send her to Jody Mills until she can get on her feet and she forgives Dean and Castiel for their roles in Jimmy's death, taking with her a gift Castiel gave her for her birthday. Dean takes back the gun, but leaves her Caddyshack and a lore book as he noticed her take Tamiel's sword and realizes she intends to become a hunter. Claire hugs Castiel goodbye, finally accepting him as her new father figure.

She goes to live with Jody Mills and appears in season 11's "Don't You Forget About Me", she is trying to be a hunter but is mentioned to have caused trouble in town, due to her hunting but doesn't face jail because of her adoptive mother being sheriff. As seen in the Winchesters' visit, she is still rebellious and tends to cause trouble for her adoptive sister Alex. While she maintains a distancing attitude to them, Dean tells her that Jody is doing her best to care for her and she starts to see his point. When she and Jody are captured by vengeful vampires one of them being Alex's boyfriend, Claire breaks free and protects them as the Winchesters arrive to save them. Claire helps Alex in killing Henry. After the attack, she accepts them as family and even tries to make breakfast though the food was burnt. In subsequent episodes, Claire and Alex are shown to have a much better relationship despite still bickering with each other.

In season 12's "Ladies Drink Free", Claire has become a full-time hunter, but lies to Jody that she is checking out colleges as she feels Jody is holding her back too much when they hunt together as Jody is somewhat overprotective. While hunting a werewolf with Mick Davies of the British Men of Letters, the Winchesters learn that Claire is on the same hunt and they team up together. By posing as a high school student, Claire is able to learn from one of the victims best friend that the girl was dating someone who creeped her friend out. Shortly afterwards, the werewolf attacks Claire in broad daylight and bites her.

Frightened, Claire begs to be killed as she doesn't believe she can control herself when she inevitably transforms, but Sam suggests trying an experimental cure created by the British Men of Letters instead. Though it has never worked on a human, Claire agrees to try it and is left with Mick as the Winchesters go to find the werewolf. As the transformation begins, Claire begs Mick to kill her, but he refuses. The two are attacked by the werewolf who is revealed to be the friendly local bartender, Justin, who abducts Claire. Justin reveals to Claire that he was once part of a peaceful pack, but after it was wiped out by the British Men of Letters, he was driven insane with loneliness and is now seeking out a mate. As Claire struggles with both Justin and her instincts, the Winchesters and Mick arrive thanks to a tracking device Mick planted on Claire. In the fight that follows, a completely feral Claire attacks Dean, but he subdues her. Mick and Sam manage to extract Justin's live blood before killing him and Dean injects Claire with the werewolf cure. Claire experiences excruciating agony over a prolonged period of time before appearing to die. Moments later, Claire's transformation reverses itself and she wakes up completely human. The next morning, Claire calls Jody and leaves her a voicemail telling Jody the truth. Claire decides to keep hunting on her own for the time being, but assures Jody that she is ready now thanks to Jody being her mother.

In "There's Something About Mary" and "Who We Are", Claire appears as one of the British Men of Letters primary targets when they plan to wipe out all of the American hunters. However, the British operation is destroyed by a team of American hunters led by Sam and Jody before this can happen.

In season 13's "Wayward Sisters", a more experienced Claire hunts a small werewolf pack that has kidnapped a young girl. Disguised as a delivery person, Claire single-handedly kills all three werewolves, rescues the girl and returns her to her mother. Afterwards, Claire receives a call from Jody that the Winchesters have disappeared and Jody needs her help. Claire returns to Sioux Falls where she is skeptical of Patience Turner's claims that she has had a vision of Claire's death. With Alex's help, Claire locates dreamwalker Kaia Nieves, only to be attacked by a strange monster. With Jody's help, Claire kills the monster which Kaia reveals comes from an alternate reality known as The Bad Place. With Kaia having been trying to help the Winchesters open a door to another world, Claire realizes that a door to The Bad Place is still open.

Under attack by the creatures, the group flees and links up with Sheriff Donna Hanscum for backup. Due to Patience's vision, Jody convinces a reluctant Claire to stay behind. As Claire bonds with Kaia, she grows worried enough to lead the other girls after Jody and Donna. Claire arrives in time to kill one of the creatures with a flamethrower and save Jody and Donna's lives. Finding the rift on the verge of closing, Jody agrees to allow Claire to go through with Kaia and stop overprotecting her. Claire and Kaia manage to rescue the Winchesters in The Bad Place, but are ambushed by a cloaked figure who throws a spear at Claire, killing Kaia when she saves Claire's life. With a giant monster approaching and the rift about to close, the Winchesters drag a reluctant Claire back through the rift which closes moments later. A devastated Claire is comforted by Jody, the true ending to Patience's vision. Claire is left devastated by losing Kaia and later joins her family for dinner, vowing revenge upon Kaia's killer even if she has to find a way to open another rift to The Bad Place. Unknown to Claire, as she sits down to a dinner, a rift from The Bad Place opens and brings Kaia's killer to the Winchesters world. Kaia's killer is revealed to be the alternate reality version of Kaia from The Bad Place.

In season 14's "The Scar", Jody and the Winchesters track down Kaia's killer while searching for a way to defeat the alternate reality Michael. Having thought a string of recent murders was a human killer, Jody initially keeps Claire out of the case for that reason and then because Claire, who was in love with Kaia, is obsessed with revenge against her killer. After catching Kaia's killer, dubbed Dark Kaia, the three learn of her identity as Kaia's alternate counterpart who admits that Kaia's death was an accident as she was aiming for Claire. After a confrontation with some of Michael's monsters, Dark Kaia escapes after saving the group's life, leaving Jody to wonder how to explain what happened to Claire.

In season 15's "Galaxy Brain", the Winchesters and Jody encounter Dark Kaia yet again who reveals that The Bad Place is dying and that Kaia is in fact still alive, trapped in The Bad Place after surviving her wound. Jody attempts to call Claire to inform her of the development, but can't reach her and they are left with no time to wait for Claire to help them rescue Kaia. Jody tells Castiel that Claire has been obsessed with hunting Dark Kaia for revenge for two years and is ironically out of cellphone range in Yosemite chasing a woman in a black cloak when they finally get Dark Kaia. The two believe that Claire won't survive if she learns that they had a chance to save Kaia and failed to save her and Castiel convinces Jody to remain behind so that Claire doesn't lose her too. With the help of Dark Kaia and Jack, the Winchesters return to The Bad Place and rescue Kaia. Dark Kaia chooses to remain behind in The Bad Place as it is destroyed by God, dying with her homeworld. In the aftermath, Kaia accepts an invitation to return to Sioux Falls with Jody and asks after Claire who Jody promises will be home soon.

Sheriff Donna Hanscum (portrayed by Briana Buckmaster) is the sheriff of Stillwater, Minnesota who, while at first oblivious to the supernatural, became a hunter after two encounters with it. She first appears in "The Purge" when Sam and Dean investigate mysterious deaths where overweight people are drained of most of their fat. Donna is portrayed as an overweight woman who has recently been granted a divorce from a man who dumped her for her weight. She helps Sam and Dean early in the investigation, but then goes to a health spa where the owner, a pishtaco, feeds on her fat, causing her to lose ten pounds, something she attributes to fire cupping. Donna, slightly stoned from the roofies she was given, inadvertently blows Sam and Dean's cover at the spa and explains her weight loss to them. After the case is over, Sam and Dean attribute it to a psychopathic serial killer, something Donna accepts.

Several months later, during "Hibbing 911", Donna goes to a sheriff's retreat in Hibbing, Minnesota, her hometown where she meets Sheriff Jody Mills. The two are partnered up during the retreat and Jody tries to keep Donna out of the case where people are completely consumed by an unknown monster except for their bones. In turn, Donna is annoyed when Jody defends her from her husband who is extremely rude to her and unknowingly makes a rude comment about Jody's own lost husband, something Donna immediately regrets when she realizes what she's done. Donna later sees Sam and Dean who Jody called in and is surprised to recognize them while Jody is shocked to realize Donna knows her friends. Donna eventually finds Sheriff Len Cues over another victim and sees that he is a monster, more specifically a vampire, shocking her. She tells Jody about it and they break into Len's room where Donna finds a clue about the location of the vampire's nest. When Sam and Dean arrive, they are forced to tell Donna the truth about what's going on in Hibbing and what happened in Stillwater. Donna insists on going with them and with the support of Jody, she successfully convinces them to let her go along, though she is a bit unsettled at the idea of having to decapitate the vampires to kill them. The group is captured by the vampires and their leader, Starr, explains that Len used to be their leader, having taught them to use all parts of their prey, before growing a conscience and leaving them. The vampires were trying to lure Len back and when he refuses, Starr kills him. Dean breaks free and kills two of the three vampires, but Starr goes after Jody. Donna, who broke one of the lenses of her glasses and used it to cut herself free, decapitates Starr, saving Jody and quipping "Hakuna Matata, lady." Later, Donna discusses the experience with Jody, saying that knowing monsters are out there makes the world seem bigger and darker. Jody, complimenting Donna's actions, offers to train her to be a hunter, something Donna accepts.

Donna later reappears in Plush, calling in the Winchesters after a man in a bunny mask murdered a local man and the mask won't come off. When her deputy, Doug, is forced to kill the young man, Donna is left horrified as the mask appears to be a cursed object, making the young man another innocent victim. Donna burns the mask and it appears to be over, but a young woman in a court jester's outfit attacks the local football coach and the Winchesters learn that they are dealing with an angry ghost, not a cursed object. Dean is able to break the ghost's possession of the young woman and Donna makes up a story and lets her go as she's innocent. As the Winchesters talk to Rita Johnson, the woman who donated all of the possessed costumes, Donna distracts her son Max. Afterwards, the Winchesters inform her it is the ghost of Chester Johnson, a children's performer who committed suicide a couple of months before. When told that they need to locate and burn the costumes, Donna offers to deal with that with Doug. She is later called by Sam after another possessed victim murders the coach who was in a coma. Donna and Doug locate all of the costumes and burn them, but when Donna calls Sam, he learns she never found a deer's head mask. After Chester's spirit is destroyed, Donna visits the Johnson house with Doug and the Winchesters tell her that as she now has three cases under her belt, she is an official hunter to her great joy. After they leave, Donna apologizes to Doug for her treatment of him due to her bad experience with her ex-husband Doug who was also a cop. Doug forgives her, telling Donna he has baggage too and the two are able to joke around with each other comfortably.

Two years later in "Wayward Sisters", Donna is called in by Jody Mills to act as backup to help rescue the Winchesters from the alternate reality known as The Bad Place. Now a full-fledged hunter, Donna is stated to have "killed a lot of vampires" and possesses an impressive arsenal in her truck. Donna helps figure out the location of the rift between worlds and battles creatures from The Bad Place alongside Jody, her daughter Alex, Claire Novak and Patience Turner. After the rescue is successful, Donna sits down to dinner with Jody's family.

A few weeks later in "Breakdown", Donna's niece Wendy goes missing. Even though all signs point to a human bad guy, Donna calls the Winchesters for help and they come to her aid alongside Doug who is now her boyfriend. The group determines that Wendy has been kidnapped by a serial abductor called the Butterfly and work together with FBI agent Terrance Clegg to try to solve the case. Along the way, Donna is forced to tell Doug the truth about monsters and her hunting lifestyle when they discover that the victims are being chopped up and sold as parts for monsters. After Doug gets turned into a vampire, Donna kneecaps his sire and forces him to divulge the location of the harvesting operation while Dean manages to cure Doug. Donna then rescues Wendy, killing the Butterfly's accomplice in the process while Dean rescues Sam and kills the Butterfly, who was Agent Clegg all along. In the aftermath, while Doug acknowledges the necessity of Donna's hunting, he becomes frightened by what he has seen and breaks up with Donna, leaving her heartbroken.

In season 14's "Nightmare Logic", Mary Winchester and the alternate Bobby Singer retreat to Donna's cabin for some down time following a hunt that brings up bad memories for Bobby.

In "Damaged Goods", Dean visits with Donna on his way to her cabin to see his mother. Donna tells him that her breakup with Doug has been hard on her with Doug leaving the police force and going into private security. Donna notices Dean's strange behavior and realizes that something is wrong. Later, a suspicious grocery store clerk calls Donna about Nick searching for Mary. Donna pulls Nick over in a stolen van and learns from Nick's fingerprints about Nick being wanted for his murder spree. Nick knocks Donna out with a stun gun and learns Mary's location from Donna's cell phone, but leaves her unconscious in the front seat of her police car rather than harming her further. Upon waking up, Donna calls Dean and warns him of the threat Nick poses. Donna's police department helps them track down Nick through his stolen van and Donna acts as a police escort to the storage unit where Nick is unleashing Abraxas. After Nick kills Abraxas, Donna shoots Nick in the leg to keep him from harming Mary and arrests Nick for his murder spree.

Eileen Leahy, portrayed by Shoshannah Stern, is an Irish hunter and Men of Letters Legacy.

In 1985, when Eileen was a baby, a Banshee attacked her house and murdered her parents. Before dying, Eileen's mother managed to banish the Banshee with a spell, saving Eileen's life but leaving her deaf. Eileen was eventually found and raised by a hunter named Lillian O'Grady who died of cancer when Eileen was sixteen.

In "Into the Mystic", Eileen tracks the Banshee that killed her parents to a retirement home in Kansas where she encounters the Winchesters. Disguised as a maid, Eileen comes to the mistaken impression that the Winchesters are Banshees and attacks Sam before they can sort it all out. The Winchesters learn that Eileen's grandfather was a Man of Letters, making her a Legacy like them. With the help of the Winchesters and Mildred Barker, Eileen finally kills the Banshee and get her revenge. However, Eileen decided to remain a hunter rather than return to a normal life.

In "The British Invasion", Eileen's help was enlisted by the Winchesters in finding Kelly Kline. Eileen eventually tracked down a demon working for the Prince of Hell Dagon and got Kelly's phone number from him before killing the demon with an angel blade. Eileen took part in the mission to capture Kelly Kline and attempted to kill Dagon with the Colt. However, Eileen missed and accidentally killed British Men of Letters operative Renny Rawlings. The Winchesters stop Mick Davies from killing a distraught Eileen and she chose to return to Ireland for a while, but not before leaving the Winchesters the Colt.

In "There's Something About Mary", Eileen is killed by a hellhound loyal to British Men of Letters assassin Arthur Ketch in South Carolina. The Winchesters learn of Eileen's death from Jody Mills and are confused and suspicious as Eileen is supposed to be in Ireland. They later receive a letter sent by Eileen four days before her death stating she believed that the British Men of Letters were following her and tapping her computer and phone. Eileen's letter causes the Winchesters to check the bunker and find Arthur Ketch's monitoring equipment. After capturing Lady Toni Bevell, the Winchesters question whether the British operation is responsible for Eileen's death. While Toni doesn't know who Eileen is, she confirms the high likelihood that she was killed by the British Men of Letters, stating that if the organization is suspected of killing someone, they likely did.

In season 15's "Golden Time", Eileen returns as a ghost, revealing that the hellhound dragged her soul to Hell when she was killed. Having escaped from Hell when God released all of the souls of Hell upon the world, Eileen seeks Sam and Dean's help in getting into Heaven, knowing that she will eventually go insane as a ghost. However, the Winchesters have learned that once a soul has been condemned to Hell, it cannot enter Heaven. Instead, Dean sends Sam to seek out Rowena's journals so they can create a Soul Catcher to contain Eileen. At Rowena's apartment, Sam discovers a spell Rowena had created to resurrect Mary Winchester which he realizes will work on Eileen also. After witches attack, Eileen is banished, but gets Dean to help Sam. Eileen battles a witch's ghost until Dean puts the witch's soul to rest. Afterwards, Sam uses Rowena's spell to resurrect Eileen.

Garth Fitzgerald IV, portrayed by DJ Qualls, is a hunter who generally works alone, although he has teamed up with the Winchester brothers on two occasions. Since Bobby's death and Sam and Dean's subsequent year-long absence, he has taken on Bobby's role as hunter coordinator, although he remains mobile where Bobby maintained a 'home base', carrying various cell phones around with him; he has even started wearing Bobby's hat and attempting to imitate Bobby's old phrases, although this has met with variable success. As part of this, he has started to track hunters via the GPS in their cell phones and assign them cases, something that creeps Sam out but Dean says is "very Bobby." Garth reveals that before he became a hunter, he was working to become a dentist and killed the Tooth Fairy on his first case.

Garth eventually disappears sometime after "Taxi Driver" and is found by Sam and Dean in "Sharp Teeth" where he reveals that he was turned into a werewolf on a hunt two months before his disappearance and hid it. Garth has joined a pack of werewolves that peacefully coexist with humans and married one named Bess. After Sam and Dean find him, he introduces them to the pack and tries to convince them that everything is fine, however, members of the pack worship Fenris and want to rule over humanity. To this end, they kidnap, Garth, Bess and Sam, planning to murder Garth and Bess and frame Sam and Dean to goad the pack into returning to their old beliefs and bring about Ragnarok. Before the plot can be carried out, Dean comes to their rescue and kills the three werewolves involved. In the aftermath, Garth, who is upset to learn of Kevin's death and blames himself as he wasn't there for him, offers to return to hunting using his new powers to help fight. However, Dean recognizes that not all of the werewolves are bad and tells Garth to stay with his new family where he has found happiness.

Needing help to discover Michael's plans, Garth returns in "The Spear", offering to go undercover and infiltrate the rogue Archangel's ranks as a werewolf seeking an enhancement. Having been briefed by Sam, he intended to fake taking the serum, but is later forced to consume it. Overwhelmed, he later attacks the approaching hunters, forcing Sam to subdue him and lock Garth in the Impala's trunk. Sam suggests that Michael was spying on them through his connection to Garth and they hope that killing Michael will free Garth from his control. Garth remains locked in the trunk throughout "Nihilism" with subsequent events preventing the original plan to retrieve Garth until after Michael is defeated and locked away in Dean's mind.

In season 15's "The Heroes' Journey", Garth calls the Winchesters in for help after Bess' cousin Brad is found badly wounded by a Wraith. Garth is shown to have three children and named the youngest two after Sam and Castiel. With Sam and Dean now experiencing normal people problems, Garth and Bess help treat Dean's seventeen cavities and Sam's illness, Garth having become a dentist since he retired. After learning of the war with God, Garth suggests that as Sam and Dean were the heroes of God's story, he had protected them from such mundane issues but has since downgraded them to normal people since the Winchesters have fallen out of favor with God. Though Garth guesses that he's only a special guest star in the story, he suggests that its better than being the hero. When the Winchesters go after the monster fight club, they leave Garth behind rather than risk his normal life. However, Garth later shows up to rescue them, infiltrating the fight club and using C4 to blow it all up. This and Garth saving them from the massive vampire Maul causes the Winchesters to suggest that Garth is the hero of the story this time. Garth directs the Winchesters to a place he has heard rumors of in Alaska where they might be able to regain their normal abilities and dances with Bess as they drive away.

Gordon Walker, portrayed by Sterling K. Brown, is a vampire hunter whose methods often put him at odds with the Winchester brothers. Gordon focuses on eliminating the supernatural simply because it isn't human, where the Winchesters are more willing to tolerate supernatural entities that are not actively killing humans. Gordon takes pleasure in considering himself a killer who freely resorts to torture, where Sam and Dean regard themselves as Hunters who only kill when they must and do nothing to their enemies that the situation doesn't force upon them.

When Gordon was 18 years old, a vampire broke into his house and abducted his sister. Gordon ran away from home, learned how to fight, hunt, and kill vampires, and tracked down the vampire who had taken his sister. He killed the vampire, and his sister, who had been turned, marking the beginning of his hatred for the undead. At some point during his career as a hunter, Gordon met John Winchester and Ellen Harvelle. Ellen described him as a skilled hunter in the sense that Hannibal Lecter is a good psychiatrist, being good at his job but dangerous to everyone else around him.

Gordon is introduced in the episode "Bloodlust", meeting up with Sam and Dean while hunting a nest of vampires. At first, Dean bonds with Gordon, but Gordon proves himself to be bloodthirsty and sadistic as he tortures one of the captured vampires, even though he knows these particular vampires feed off cattle blood and do not kill humans. After Gordon tries to force one of the vampires to drink Sam's blood while torturing her with dead man's blood, Dean, seeing the vampire resist the urge, ends up beating Gordon in a fight and leaves Gordon tied to a chair while the vampires escape. Later, while performing an exorcism, Gordon learns about the coming demonic war, Azazel's special children, and Sam's powers. In "Hunted", he kills Scott Carey- another of the 'special children'- and then tracks Sam down and tries to kill him, convinced that Sam and those like him are 'traitors' to humanity. However, Dean intervenes, and, after a scuffle, Gordon knocks Dean out, ties him up, and uses him as bait to catch Sam in a booby trap of grenades set with trip wires. Sam manages to evade the trap and knocks Gordon out. As the brothers leave the damaged house, Gordon regains consciousness and chases them, firing two pistols in their direction. The police arrive to subdue Gordon, based on an anonymous tip from Sam, and find his cache of weapons in his car.

In "Bad Day at Black Rock", Gordon is shown to be in prison, where he convinces a visiting fellow hunter to go after Sam Winchester, convinced that Sam was involved in the opening of the Devil's Trap regardless of Bobby's claims that Sam was actually trying to stop it. Gordon eventually escapes from prison and, once again, pursues the Winchester brothers in "Fresh Blood". However, he is captured and subsequently turned by a vampire. Gordon, however, turns on his sire, kills two other vampires, and then sets up a trap for the Winchester brothers, still convinced it is his duty as a hunter to rid the world of Sam Winchester. A fight ensues in a warehouse where Gordon holds a girl he has kidnapped—and turned—to use as bait, ending with Sam decapitating him with a garotte improvised out of razor wire.

According to series creator Eric Kripke, Gordon was originally going to learn about the hunter Sam killed while possessed and use it to convince more hunters to turn against Sam. This was intended to be a story arc stretching over multiple episodes. However, Sterling K. Brown was contracted for the Lifetime Television series Army Wives, and Lifetime would only allow him to return to Supernatural for two more episodes.^[81]

Gwen Campbell, portrayed by Jessica Heafey, is a hunter and third cousin related to Sam and Dean's mother's side of the family. When Sam re-enters Dean's life in "Exile on Main Street", he reveals that he has been back for a year and hunting with the Campbells, including Gwen. She and the others assist the brothers in defeating a Djinn. Gwen is present at the compound in "Two and a Half Men" when the brothers arrive with a baby Shapeshifter, and is overpowered, along with the others, when the Alpha Shapeshifter arrives. When hunting the Alpha Vampire in "Family Matters", she is ordered to stay behind and flush out any stragglers with Dean. She and Dean fight well together, and she covers for Dean when he disobeys orders. However, she sides with Samuel at the end of the episode when she holds the Winchesters at gunpoint, and follows him even when it is revealed that he has been working for Crowley. She is next seen in "...And Then There Were None", hunting with Samuel. While investigating a series of murders, they encounter Bobby, Rufus, Sam and Dean. Gwen tells Dean that she did not know that Samuel had betrayed them to Crowley. The creature responsible for the deaths—dubbed the Khan Worm—infects Dean, who kills Gwen.

Henry Winchester, played by Gil McKinney, is John Winchester's father, Sam and Dean's grandfather and a member of the secret society known as the Men of Letters. Vanishing in 1958, Henry was believed by his son to have run out on his family.

Lily Sunder, portrayed by Alicia Witt, is a professor of apocalyptic literature turned angel hunter appearing in season 12. She reappears in season 14 portrayed by Veronica Cartwright.

In the late-nineteenth to early-twentieth century, Lily worked as a professor of apocalyptic literature and was fascinated by angels. She eventually found a spell to summon one, Ishim, who taught her the secrets of the angels. However, Ishim grew dangerously obsessed with Lily. Recognizing that Ishim was a monster, Lily left him and married the Seraphim Akobel for protection. However, in 1901, Ishim came after her for revenge. Accompanied by the angels Benjamin, Mirabel, Castiel and two others, Ishim arrived under the pretense that Lily's daughter May was a Nephilim that had to be killed. Akobel ordered Lily to run while he confronted the angels and was killed. Ishim faced Lily alone and murdered May in front of her before leaving Lily alive. Desiring revenge, Lily began using Enochian magic to give herself immortality and various powers at the cost of parts of her soul burning away each time she used them. After the Fall of the Angels in 2013, Lily took advantage of the angels' weakened state to kill two of Ishim's garrison that had participated in murdering her family over the next few years.

En 2017, en " Lily Sunder Has Some Regrets ", Lily se enfrenta a Benjamin en una sala de juegos y lucha contra el ángel. Tras permitir que Benjamin emita una señal de auxilio, Lily lo mata con una espada angelical. A continuación, Lily se enfrenta a Mirabel fuera de un restaurante donde se reúne con Ishim y Castiel, sus últimos objetivos. Lily mata rápidamente a Mirabel y centra su atención en Ishim cuando este aparece. Los nuevos poderes de Lily le otorgan inmunidad a los ataques de Ishim y lo hiere, pero la pelea es interrumpida por los Winchester y Castiel. Tras resultar herida y sin querer dañar a los humanos, Lily usa un rayo de luz blanca para cegar a todos y huye en un coche de alquiler a su hotel, donde se recupera de sus heridas.

Tras enterarse de lo sucedido en 1901, los Winchester localizan a Lily a través de su coche de alquiler para intentar convencerla de que no persiga a Castiel. Al descubrir que creen que May era una Nephilim, Lily les cuenta la verdad. Sam y Dean le creen, y Dean parte en busca de Castiel mientras Lily se queda con Sam y lo convence de la amenaza que Ishim representa para Dean. Lily y Sam llegan justo cuando Ishim se prepara para matar a Dean, y Lily se enfrenta a él en combate. Incluso con la ayuda de los Winchester, Lily demuestra no ser rival para Ishim, quien lucha mediante su telequinesis y se prepara para matarla con su espada angelical. Para sorpresa de Lily, Castiel la salva matando a Ishim por la espalda con su espada angelical. Aunque Lily consigue su venganza con la muerte de Ishim, se queda con la duda de si podrá abandonar su sed de venganza contra Castiel, ya que la venganza ha sido lo único que ha tenido durante más de un siglo. Castiel se disculpa con Lily y le promete que si algún día no puede perdonarlo y quiere vengarse, él la estará esperando. Entre lágrimas, Lily le da las gracias a Castiel y se marcha, presumiblemente para comenzar una nueva vida.

En "Byzantium", Sam llama a Lily para pedirle ayuda con la esperanza de que pueda traducir las notas de Kevin Tran en la tablilla angelical y encontrar una manera de resucitar al fallecido Jack. Ahora anciana, pues ha dejado de usar la magia que prolongaba su vida, Lily no puede leer las notas de la tablilla, pero ofrece una forma de salvar a Jack usando su magia enoquiana, que permitirá que la propia alma de Jack lo sostenga. A cambio, Lily pide a los Winchester que le aseguren la entrada al Cielo, explicando que aún le queda un fragmento de su alma y desea reunirse con su hija cuando muera. Los Winchester invocan a Anubis, quien pesa el alma de Lily y determina que irá al Infierno. Anubis explica que solo las decisiones de una persona determinan su destino final y que él no puede cambiar el destino de Lily. A pesar de este revés, Dean convence a Lily para que los ayude y así no tengan que experimentar la pérdida de un hijo como ella la sufrió. Lily logra resucitar a Jack y curar su enfermedad.

Moments after Jack's resurrection, Lily suffers a fatal heart attack and quietly dies. In the afterlife, Lily is greeted by Anubis who again weighs her soul and determines that Lily can now enter Heaven. Lily is implied to have known that helping Jack would be fatal to her and helped anyway and that this selfless action changed her fate. Anubis sends Lily's soul off to be reunited with her daughter at long last with Lily smiling in happiness and peace.

Mary Winchester (née Campbell), regularly portrayed by Samantha Smith but depicted by Amy Gumenick in the time travel episodes "In the Beginning" and "The Song Remains the Same" and by Meg Donnelly in the sequel series The Winchesters, is the wife of John Winchester and mother of Sam and Dean. The Season 4 episode "In the Beginning" revealed that Mary was a hunter herself and that her family had been hunters for generations. She was born in 1954 to Samuel and Deanna Campbell, both hunters, who would be her sons' namesakes.

Rufus Turner, portrayed by Steven Williams, is a semi-retired hunter who helped Bobby Singer when his wife, Karen Singer, was possessed by a demon. Rufus exorcised the demon and helped cover up Karen's death. It is Rufus who introduced Bobby to the world of the supernatural, and they hunted together for many years until a hunt went wrong in Omaha, Nebraska, and someone important to Rufus died. They became estranged after this. Fifteen years later, Rufus responds to Bobby's request for information on Bela Talbot and helps Dean locate her in "Time Is On My Side." He returns to active hunting after Lucifer rises and the Apocalypse begins.

Rufus is introduced in the third-season episode "Time Is on My Side" when Bobby, who has not heard from Rufus in about 15 years, receives a phone call in which Rufus alerts him to the whereabouts of Bela Talbot. Dean visits Rufus, even though Sam opposes the idea of hunting for Bela, as they have only a couple of weeks until Dean's deal runs out. Rufus presents Dean with a manila folder on Bela, which gives Dean new and interesting details from her past.

Rufus appears off-screen in "When the Levee Breaks", when he calls Bobby with news of more of the 66 Seals being broken.

In "Good God Y'All", Rufus heads to a town he thinks is under attack from demons, based on omens of a polluted river and a falling star. He calls Ellen, Jo, and Bobby for help. When Sam and Dean arrive, he and Jo have been separated from Ellen. Jo and Rufus capture Sam, thinking he is possessed. Later, Ellen and Dean help break the spell War has over them. Bobby talks on the phone to Rufus about omens that may indicate the appearance of Death, in "The Devil You Know".

In "Weekend at Bobby's", Rufus arrives at Singer Salvage Yard to dispose of the body of an apparently dead Okami. Bobby assists him and helps him evade capture by the FBI. However, the Okami is revealed to still be alive and is subsequently dispatched by Bobby. Afterward, Rufus uses his contacts to uncover information on Crowley's life as a human and later steals a signet ring from a museum which once belonged to Crowley's son as part of Bobby's attempt to regain his soul from the demon. Rufus investigates the same case as the Winchesters and Bobby, in "...And Then There Were None". The group later encounters Samuel and Gwen Campbell, and discover that the monster is a new breed created by Eve, the "Khan Worm." After Gwen and Samuel are killed, Rufus is stabbed by a possessed Bobby. As cremation is not undertaken in the Jewish tradition, Rufus is buried in a Jewish cemetery rather than given a Hunter's funeral pyre. Bobby pours some of Rufus' favorite drink—Johnnie Walker Blue Label—on the grave before taking a drink himself.

After becoming comatose from being shot in the head by Dick Roman, Bobby relives various memories of Sam, Dean, Karen, his family, and Rufus. Remembering Rufus has a traumatic effect on Bobby, and he reveals to Rufus that he is just a memory appearing in Bobby's comatose mind. While initially disbelieving, Rufus accompanies Bobby in a quest through the past in which Bobby confronts his worst memories to momentarily recover from his gunshot wound.

In "Safe House", flashbacks show a case Bobby and Rufus worked together during the fourth season where Rufus called Bobby for help on an apparent haunted house. However, the two eventually realized they were dealing with a being known as a Soul Eater rather than a ghost. Unable to kill the Soul Eater, Rufus painted a sigil that would trap it, but the Soul Eater pulled Bobby's soul out of his body and into its "nest" outside of time and space, using Bobby to attack Rufus. Rufus subdued the possessed Bobby and finished the sigil, trapping the Soul Eater in its nest. He later leaves Bobby the bottle of Johnny Walker Blue found by Sam and Jody Mills in "Time After Time" since Bobby was right about what they were dealing with and brushes off Bobby's concerns about how he escaped the nest.

Samuel Campbell, portrayed by Mitch Pileggi and Tom Welling, is the maternal grandfather of Sam and Dean Winchester, and Sam Winchester's namesake.

Based on the historical gun maker of the same name, Samuel Colt is a hunter who lived in the 19th century and the creator of the Colt—a gun that can kill almost any supernatural being; Lucifer revealed that he is one of five supernatural beings immune to its powers. Colt also designed the locked door that keeps the portal to Hell known as the Devil's Gate from opening. The Devil's Gate and the Colt gun are linked together—the gun serves as the key to the gate, allowing it to be opened by inserting the Colt's muzzle into the key hole. Colt also built a railroad of iron, in the shape of a pentagram with a church at each of the points, around the devil's gate to further ensure that it was demon-proof. Colt was portrayed by Sam Hennings in the season six episode "Frontierland". Sam and Dean, when looking for a method of destroying Eve, come across Colt's journal which reveals that the hunter had killed a phoenix in 1861. As the ashes of a phoenix are needed to kill Eve, Castiel sends Sam and Dean back in time to retrieve them. Although Samuel is initially reluctant to assist Sam, he eventually gives him the Colt which Dean kills the phoenix with. When Sam and Dean are pulled back to the present day without the ashes, it is revealed that Colt sent a courier package 150 years ago containing the ashes, which arrives at Bobby's door. He was able to figure out how to use Sam's cell phone, which he left behind (and which Colt sent back to him), and learned the date and Bobby's address from it.

Walt and Roy are two hunters first appearing in season 5's "Dark Side of the Moon." Having learned of Sam's role in starting the Apocalypse, the two hunters ambush the Winchesters in a motel room with the intention of killing Sam whom they see as a monster. After Dean recognizes both men, they decided to kill both Winchesters rather than risk Dean's wrath. Dean promises that when he inevitably returns, he will hunt them down and kill them for revenge. The Winchesters are sent to Heaven after the murder and are eventually resurrected by the angel Joshua on the orders of God.

Both Walt and Roy return in season 12's "Who We Are" as two of the hunters called in to help deal with the British Men of Letters situation by Jody Mills. Having not seen the Winchesters since murdering them in "Dark Side of the Moon", the reunion is somewhat awkward, but Dean assures both men that there are no lasting hard feelings over their actions. Walt and Roy join Sam's assault on the British Men of Letters base with Roy even saving Sam's life from a British operative that Sam misses. Roy is killed during the assault by another operative that Sam shoots moments later, but Walt survives. Walt, who acts as the team's explosives expert, joins Sam and Jody in confronting Doctor Hess and follows Sam's lead during the confrontation.

Walt is mentioned again in season 13's "Wayward Sisters" as one of the hunters contacted by Alex Jones when the Winchesters disappear. Like the other hunters, Walt has seen no sign of them but promises to keep looking.

Adam Milligan, portrayed by Jake Abel is the illegitimate son of John Winchester and the half-brother of Sam and Dean Winchester. He was born from a relationship between John and a woman named Kate Milligan, while John was on a hunt. At age 12, he begged his mother to call his father and from then on they would have sporadic contact, but John never told Adam of his other sons, who had no idea about Adam's existence. Despite John's attempts at parenting, Adam never saw John as his father and viewed his mother as his only family, but still wished to have a closer relationship with his father.

His existence is revealed to Sam and Dean in Jump the Shark, in which he was murdered by ghouls along with his mother, as the ghouls wanted revenge on John for the murder of their father. One of the ghouls took on Adam's identity to lure John to them. However, as John was already dead, his other sons got the call and were shocked to learn of their half-brother. During their investigation, Adam's body was discovered by Dean, just as Sam was attacked by the ghouls, who settled for killing Sam and Dean. Dean killed the ghouls, avenging Adam's death and they subsequently gave a hunter's funeral for the brother they never knew.

In season 5's "Point of No Return", Adam is resurrected by Zachariah to serve as Michael's vessel after Dean's continuing refusal to say yes. However, Castiel senses Adam's resurrection and is able to get to him before the angels do and the Winchesters, Castiel and Bobby continually try to talk Adam out of his plan without any luck as Zachariah has promised to bring back his mother in exchange for Adam's help. Zachariah eventually appears to Adam in the form of a dream and convinces him to reveal where the Winchesters are keeping him. Zachariah takes Adam to the Green Room where he reveals that Adam's resurrection was actually a trap to get Dean to say yes, using Dean's weakness for his family against him. The Winchesters storm the Green Room to Adam's surprise and Zachariah tortures both Sam and Adam to finally get a yes out of Dean. However, at the last minute, Dean changes his mind and kills Zachariah with an angel blade. As the three humans try to flee, the descending Michael traps Adam in the Green Room with himself and Zachariah's body and the room disappears when the Winchesters try to get back inside. Both Sam and Dean acknowledge that neither Adam nor Castiel are likely alright and vow to get them back.

In "Two Minutes to Midnight", Castiel reveals to Sam that Adam has now become Michael's vessel for the rapidly approaching final battle which Sam admits is a possibility that they didn't really want to consider.

In "Swan Song", Adam is Michael's vessel when he meets with Lucifer in Stull Cemetery for the final battle of the Apocalypse. When Dean arrives, he tries to apologize to Adam, but the archangel tells him that "Adam isn't home right now." After retaking control from Lucifer, Sam throws himself, Lucifer, Michael and Adam into Lucifer's Cage to stop the Apocalypse.

In season 6's "Appointment in Samarra", Dean is offered the choice of saving Adam or Sam from Hell by Death and he chooses Sam though he does ask Death to save Adam too without success.

In season 10's "Fan Fiction", the Winchesters are confused when, during a play based on the Supernatural books, a character they don't recognize comes on stage. Maeve tells them that it is Adam who is still stuck in Hell with Lucifer. Sam and Dean's reactions suggest that they have forgotten about Adam.

In season 15's "Our Father, Who Aren't In Heaven", Adam, still Michael's vessel, has escaped from Hell after God threw every door in Hell open, including the door to Lucifer's Cage. Now sharing control of his body with the archangel, Adam enjoys eating a variety of food for the first time in ten years and discusses with Michael, appearing as a duplicate of Adam himself, what they will both do now. The two have bonded during their time in the cage and Adam indirectly suggests that they stay together, which Michael does not seem opposed to. Adam's meal is interrupted by the arrival of Lilith seeking Michael on God's orders, ending with Michael killing the demon. Michael later returns control to Adam after he is captured by the Winchesters and Adam explains that he and Michael reached an agreement during their years in the Cage when they only had each other for company. To Michael's surprise, Adam sides with his brothers on the matter, pointing out that while he doesn't forgive them, he knows Sam and Dean always try to do the right thing. Adam eventually gets Michael to admit that he refuses to doubt God as he feels that is a betrayal of who he is. Michael isn't convinced to help until Castiel shows Michael his own memories of God's betrayals. As Michael prepares to leave, he returns control to Adam at Dean's request. Dean apologizes to his brother for what happened to him, stating that Adam is a good man and didn't deserve what happened to him. Adam quips "since when do we get what we deserve?" and wishes them luck before departing with Michael.

In "Inherit the Earth", Michael sadly reveals that Adam was killed along with the rest of humanity by Chuck, although the archangel continues to use Adam's body as his vessel. Chuck subsequently obliterates Michael for his betrayal, taking with him Adam's body. However, Jack restores everyone Chuck killed, meaning that Adam is restored as well.

Arthur Ketch, portrayed by David Haydn-Jones, is a former British Man of Letters. Ketch is first mentioned while Lady Toni Bevell is torturing Sam for information. When all their methods prove fruitless, Ms. Watt suggests bringing in Ketch; however, Toni is vehemently against it. He's also shown in a flashback killing a vampire, identifiable by the tattoo on his hand. Later on, Mick Davies retrieves Toni and informs her that he has sent for Ketch, who is shown preparing to leave the UK. This leaves Toni visibly uncomfortable.

In "Season 12, American Nightmare", Ketch drives up to the Impala on a motorcycle and stares at it or a moment before driving away. He later tracks down and kills Magda Peterson, telling someone on the phone that he cleaned up the Winchesters mess and they were right about the Winchesters being unable to kill her.

In "LOTUS", Ketch rescues the Winchesters and Castiel from the Secret Service and orders Castiel to wipe their memory before introducing himself. That night, Arthur explains that his job is to "strongly encourage" the Winchesters cooperation with the British Men of Letters and was sent by Mick Davies after Sam called him and hung up. Ketch has Castiel confirm that he's not lying and shows them his arsenal of weapons, including a hyperbolic pulse generator capable of exorcising a demon from its vessel. Recognizing its potential, Sam asks to borrow it and for Ketch to trust them. Ketch eventually gives the Winchesters the generator, enabling them to force Lucifer from President Jefferson Rooney and send Lucifer back to his Cage.

Six weeks later, Castiel contacts Arthur Ketch and Mick to help him and Mary find Sam and Dean who have been taken prisoner by the Secret Service. The two men are impressed to learn that the brothers had in fact borrowed Arthur's gadget to deal with Lucifer himself. They agree to help in hopes that it will earn them the trust of the American hunters, and through their connections, Arthur and Mick locate Sam and Dean near Site 94.

Once the four encounter Sam and Dean, Arthur is unimpressed to learn that they left survivors. Sam insists the people pursuing them were just soldiers doing their job, though Arthur considers it "unprofessional". Sam, Dean and Castiel head to Mary's car while glaring at Arthur suspiciously. Arthur and Mick watch them drive off and share a knowing look at each other. It is later revealed that Arthur went back and killed all those involved in Sam and Dean's imprisonment, including Agent Rick, Agent Camp, the soldiers and the coroner. Mick reports this while noting that cleaning up loose ends is Arthur's job.

In "Stuck in the Middle (With You)", Mary visits Arthur after stealing the Colt and tells him the story of its theft from Ramiel. Mary is enraged that Arthur sent her after a Prince of Hell which got Wally killed and threatens to destroy the British Men of Letters if something happens to her sons. Arthur apologizes, claiming not to have known that she was going after a Prince of Hell. Arthur and Mary discuss the legend of the Colt as an excited Arthur unwraps it.

In "The Raid", Mary and Arthur take out a vampire nest together and Arthur expresses his dislike for them trying to recruit the Winchester brothers when they have Mary. Arthur later visits Dean at the Men of Letters bunker and sits down for a drink with him. Rather than trying the sales pitch of the other British Men of Letters, Arthur is frank with Dean about his motives, telling Dean that he is a killer and the British Men of Letters offer him the best chance to express his talents. Arthur sees Dean as the same as him and the two decide to take down a vampire nest together. At the nest, Arthur initially arms himself with a gun, but decides to use a machete instead like Dean. The two men find only one vampire hiding in the nest and Arthur beats upon her before Dean stops him to try things his way. When Dean promises to grant the vampire a quick end, she tells them that her nest is going after the British Men of Letters.

Alarmed, Dean and Arthur rush back to the British Men of Letters compound to find that Sam has killed the Alpha Vampire and the surviving vampires have fled. Mick berates Arthur who tells him he was trying to recruit Dean and would have succeeded if Mick's operation hadn't screwed things up. He then takes the rogue hunter Pierce Moncrieff for punishment.

In season 13, a resurrected Arthur returns as a mercenary hunter separated from the British Men of Letters who are unaware of his survival. In "War of the Worlds", he is going by the alias of Alexander Ketch, pretending to be Arthur's twin brother. However, Dean sees through the disguise and Arthur explains that he had made a deal with Rowena for a resurrection spell that he needs recharged which brought him back after Mary killed him. Arthur saves the Winchesters from a group of demons and insists that he is on their side and that his previous actions only came from being a soldier on the opposite side of a war from them. When Dean tries to kill Arthur again, he flees and is later seen being employed by the Prince of Hell Asmodeus who is preparing to procure Jack for the Alternate Michael's invasion.

In "Devil's Bargain", Asmodeus supplies Arthur with an angel blade and sends him to kill the weakened Lucifer, believing Lucifer to be vulnerable to an angel blade in his current state. Arthur once again encounters the Winchesters who have Castiel knock him unconscious and lock him in the Impala's trunk, intending to kill him and scatter his ashes to make his death permanent. Arthur once more escapes confinement, just in time to use a demon bomb to drive Lucifer and Anael away, saving the Winchesters and Castiel. Stating that Lucifer being loose upon the Earth is a line too far for him, Arthur reveals his alliance with Asmodeus and offers to work with the Winchesters as a double agent to stop Lucifer, Asmodeus and the threat of an alternate reality Michael. Recognizing that they need him, the Winchesters reluctantly agree to the alliance. Upon Arthur's return to Asmodeus' lair, Asmodeus reveals that he has acquired the Archangel Blade, the one weapon that can kill an archangel such as Lucifer or Michael. After Arthur points out that the blade can only be used to kill an archangel by another archangel, Asmodeus introduces him to the captive archangel Gabriel who has been believed dead for nearly eight years.

In "The Thing", Arthur discovers that Asmodeus has been injecting himself with Gabriel's grace to power up. Arthur's continuing impertinence and defiance enrage Asmodeus who brutally beats him. Asmodeus states that Arthur is more wicked than any demon he knows "and I know 'em all", but recognizes that Arthur seeks redemption for his past actions which he doesn't think that Arthur can get. Once Asmodeus leaves him alone, Arthur gets back at him by rescuing Gabriel and steals Asmodeus' store of Gabriel's extracted grace as well as the Archangel Blade. Arthur brings all three to the Winchesters, seeking sanctuary from Asmodeus in return which Dean agrees to. After the Winchesters open a rift to Apocalypse World, Arthur decides to join Dean on the mission, feeling that he is safer in another universe when Asmodeus will inevitably come looking for him.

In "Bring 'Em Back Alive", Arthur teams up with a reluctant Dean to find and rescue Mary and Jack. The two witness several angels executing resistance fighters and taking captive Charlie Bradbury, the alternate counterpart of an old friend of Dean's. Against Arthur's wishes, Dean sets out to rescue Charlie, the two men being forced to work together to survive. Along the way, Dean tells Arthur of his inability to save Charlie and Arthur admits his own regrets that he never even tried to save the lives of those he cares about. Together, Dean and Arthur raid a POW camp, killing several angels and liberating Charlie and several other human prisoners. With the rift closing, Arthur chooses to remain behind in Apocalypse World with Charlie to continue the mission to find Mary and Jack and to help coordinate for Dean's inevitable return with reinforcements. As angels attack the rift, Arthur engages in battle with them alongside Charlie.

In "Exodus", Arthur has become a full-fledged member of the Apocalypse World resistance and joins Charlie on a mission to ambush an angel death squad. However, it turns out to be a trap and both are captured. Arthur undergoes extensive torture for information on the resistance, but refuses to break, even taunting his captors. The angels call in an alternate reality Castiel to tear the information from Charlie's mind, but Sam, Dean, Mary, Jack and Castiel arrive to rescue them, killing all of the angels, including the alternate Castiel. As Dean helps him, Arthur comments on the irony of Dean saving his life for once. Arthur joins the later exodus through the rift and is one of the first through. In the bunker, he and Rowena express shock at the sight of each other before Arthur moves on. During the later party, Arthur enjoys a drink with Charlie. He is mentioned to be off doing his own thing in "Let the Good Times Roll".

In season 14's "Stranger in a Strange Land", Arthur is mentioned to be following up on a lead in London in the search for a way to save Dean from Michael's possession. Sam later gets a call from Arthur and tells Castiel that Arthur has been searching for the hyperbolic pulse generator, the device they used to exorcise Lucifer out of the President in the hopes that it can be used to eject Michael from Dean. However, Arthur has had no luck in his search. In "The Spear", Arthur has found the hyperbolic pulse generator, but is forced to mail it to the Winchesters who are less than pleased as they need it immediately. Somewhat stunned, Arthur apologizes for his inability to deliver it to them directly. Though the Winchesters find the package, the device is destroyed by Michael before they can use it. In "Jack in the Box", Arthur is unable to attend Mary's hunter's memorial. Instead, he sends a bottle of the same expensive scotch he'd brought Dean in "The Raid."

In season 15's "Raising Hell", Arthur arrives in Harlan, Kansas after God releases all of the souls in Hell upon the world. After meeting the demon Belphegor, Arthur reveals that he was hired to assassinate Belphegor by the demon Ardat who claims that Belphegor is "a monstrous threat to humanity". As this doesn't seem to be the case, Arthur refrains from harming the demon and assists the Winchesters and Rowena in finding a way to contain the souls, developing a mutual attraction with Rowena in the process. Arthur is later possessed by the ghost of Francis Tumblety, forcing Dean to shoot him with iron bullets to expel Francis. With Castiel unable to heal Arthur, he is taken to the hospital for treatment and takes Dean shooting him good-naturedly.

In "The Rupture", after awakening in the hospital, Arthur prepares to leave to help his friends, only to have Ardat arrive. Unable to defeat the demon, Arthur refuses to give up his friends for any price, something that Ardat recognizes. Ardat rips out Arthur's heart and after showing it to him for a minute, crushes Arthur's heart, killing him. Ardat later poses as Arthur using his phone to trick Dean into revealing where the Winchesters are and what they are up to. His death is subsequently avenged when Belphegor kills Ardat, but not before she reveals to Castiel that Belphegor truly is the threat she'd claimed to Arthur when she hired him to kill Belphegor. At the end of the episode, Dean reveals to Sam that the other hunters found Arthur and that he was probably killed by a demon. Having just lost Rowena as well, both Sam and Dean are devastated by the news.

Ash, portrayed by Chad Lindberg, is a mullet-wearing computer expert, who works and lives at Harvelle's Roadhouse with Jo and Ellen Harvelle. He attended MIT, but was kicked out for "fighting". He owns a homemade laptop, which he uses to track the paranormal, particularly Azazel, with the information John Winchester and his sons, Sam and Dean, have gathered. In the episode "All Hell Breaks Loose: Part 1", he calls Dean to tell him he has discovered something important, but by the time Dean arrives at the Roadhouse to talk, the Roadhouse has been burned to the ground, and Dean finds Ash's corpse in the rubble.

Series creator Eric Kripke stated that Ash's death "had to do with how much I hated the actual Roadhouse itself rather than anyone in it." As for the character's return, Kripke replied, "Ash is a possibility."^[81] This comes to fruition in the fifth-season episode "Dark Side of the Moon", in which Sam and Dean meet Ash in Heaven, as well as Pamela. Enjoying the afterlife more than his actual life, and having discovered means to infiltrate other people's Heavens and tap into the angel's communications, Ash helps the brothers hide from Zachariah. Ash also revealed to them that they have died more times than they know and he has helped them before, with the angels erasing their memories upon resurrection.

Becky Rosen, portrayed by Emily Perkins, is a fan of the "Supernatural" series of books. Her online name is samlicker81, and she is the webmistress of morethanbrothers.net. She writes Wincest fanfiction. Carver Edlund aka Chuck Shurley contacts her to get a message to Sam and Dean in "Sympathy for the Devil". She initially believed it to be a joke but Chuck told her that his stories were real and she was excited as she thought so. It is obvious from her reaction to the boys that she is a Sam Girl, and fixates upon him much to his dismay.

Becky Rosen "borrows" Chuck Shurley's phone, pretending to be him, and texts Sam & Dean saying he's in a life or death situation in "The Real Ghostbusters". Sam and Dean rush over after driving all night only to find out that Becky has invited them to a Supernatural Convention for Chuck's books. When real ghosts start attacking people, Chuck has to step up and help keep everyone safe while Sam and Dean and two Supernatural fanboys, Demian and Barnes, fight the ghosts. His bravery impresses Becky who immediately abandons her pursuit of Sam for a relationship with Chuck. She also tells Sam that in the book which covers the events of "Time Is on My Side", Bela gave the Colt not to Lilith but to her right hand demon, and possibly lover, Crowley.

In "Season 7, Time for a Wedding!" a Crossroads Demon named Guy gives her a love potion to make Sam marry her, she believed Guy was a Wiccan until the demon betrays her and shows her his eyes. Guy asks for her soul in exchange for making the effect permanent, he wanted to make a deal after seeing she was married to the skilled hunter even agreeing with her about Sam easily killing. Sam warned her not to go through with the deal. According to her, Chuck broke up with her, which is presumably her reason for fixating on Sam again. During the battle at the end, she helps trap the demon, but his minion breaks him free. As the demon and his minion Jackson are about to kill the hunters, Becky retrieves Ruby's Knife and kills Jackson with it, allowing the Winchesters to overpower the Crossroads Demon whose deals are revoked by Crowley who is bemused when she excitedly recognizes him. Later, she and Sam get an annulment.

In "Slumber Party", it is revealed by Charlie that Becky posted all of Chuck's unpublished manuscripts to the Internet, with the result that the public is now 'aware' of events in Sam and Dean's lives up to the confrontation between Lucifer/Sam and Michael/Adam. When asked if they know her, Sam quickly denies it.

In "Atomic Monsters", Chuck visits Becky for help though she is less than pleased to see him. Though still a fan of Supernatural, Becky is not quite so obsessed anymore and has married and had children. Becky agrees to edit Chuck's newest story and provides critique that essentially acts as meta references for both the episode and the show itself. Becky's words causes Chuck to write a much darker ending, much to Becky's horror. When her family comes home, Chuck causes them to vanish with just a snap of his fingers, though Chuck claims that he has simply sent them "away". Revealing his true identity as God himself to Becky, Chuck causes her to vanish into thin air also with a snap of his fingers.

Ben Braeden is the son of Lisa Braeden, a woman Dean once spent a weekend with in August 1999, portrayed by Nicholas Elia. Lisa and Ben live in Cicero, Indiana. Though Dean suspects he is Ben's biological father, Lisa claims that this is not so.

Dean drops in to visit Lisa in "The Kids Are Alright", while investigating a case, on what happens to be Ben's 8th birthday. Dean meets Ben and is struck by his familiar rock-music loving, girl ogling ways, but Lisa assures Dean that he is not Ben's father. Later Dean helps Ben out in an encounter with some bullies. Although his advice, to "kick the kid in the nuts", does not get Lisa's approval, Ben hugs Dean in thanks. Later Ben is one of the children taken by a mother Changeling, and one of her offspring imitates Ben and starts feeding on Lisa. Dean and Sam rescue all the children and kill the head Changeling, destroying the imitation Ben. Dean is impressed by Ben's cool headed behavior during the rescue, having put Ben in charge of helping the other children out a window.

When Dean returns to Lisa after the showdown in Stull Cemetery, in "Swan Song", Ben is seen at the dinner table.

Dean lives with Lisa and Ben for a year, but after an attack he insists they move and is conflicted by his desire to remain with his new family, his desire to hunt and the fear that he is raising Ben as his father raised him. Eventually, Lisa lets him go in "Two and a Half Men". Dean talks to Ben on the phone in "The Third Man". After believing he is about to die after having been turned into a vampire in "Live Free or Twi-Hard", Dean returns to say goodbye. However, he struggles to control his vampiric urges and shoves Ben and flees. Ben tricks Dean into returning once more in "Mannequin 3: The Reckoning"; however, he fails to reconcile with Lisa and Dean explains to Ben that he fears that if he stayed around, Ben would end up like him. Ben is still upset and accuses Dean of abandoning his family. Ben and Lisa are kidnapped by the demon Crowley, in "Let It Bleed", in an attempt to force Dean to stand down. After they are rescued, Dean asks Castiel to wipe Ben and his mother's memories of him, which he does.

Cole Trenton, portrayed by Travis Aaron Wade, is a military brat and an ex-Marine whose father, Edward, was killed by Dean Winchester in 2003, making him bent for revenge against his father's killer all his life. During his time in the military, he took part in the campaigns in Iraq, Darfur, and DR Congo and established many connections, including his longtime friend Kit Verson and a member of the Military Intelligence. Though Cole is not a hunter and leads an ordinary life with a wife and a son, he is an expert at martial arts and is fit due to his time as a soldier, and he also keeps a rifle that is associated with hunters. He tracks Dean upon the latter's sighted attack at a store captured by a surveillance camera and beats Sam, attempting to use him as a hostage. When Sam escapes, Cole follows him as the latter is about to meet Dean at a bar. However, though he finally confronts his father's killer, Dean easily defeats him with his demonic powers, but spares him as he wants Cole to live in humiliation for failing to avenge his father. Cole does not give up, however, and he begins studying about demons and starts to torture demons in hopes of tracking Dean once more. Cole holds Dean at gunpoint when the latter is cornering Rowena, forcing Dean to let her go, and sprays holy water against him, but as Dean is no longer a demon at that point, it does not work. He is defeated once again, but Dean offers to explain his motive of why he killed Edward: Edward was a monster who had killed many people and eaten their livers, and he would have killed Cole and his mother had Dean not killed him earlier. Convinced by Dean and Sam, Cole decides to drop his revenge and return to his family.

Later, Cole with Dean and Sam work together to help his friend, Kit, after the latter's wife, Jemma, reported his weird actions. Upon finding out that Kit is possessed by a Khan Worm, Cole is concerned that the Winchesters would try to kill him like they did with countless others, including his father. Cole is possessed by a Khan Worm, but Dean manages to save him by dehydrating the room and causing the monster to flee. However, the three are too late to stop Kit from succumbing to the parasite even further, and Sam has to kill him because of it. Cole thanks the brothers for saving him, but hopes that he will never see them again.

Ed Zeddmore and Harry Spangler, portrayed by A.J. Buckley and Travis Wester, are self-proclaimed professional paranormal investigators. They are introduced in the episode "Hell House" written by Trey Callaway as the Hell Hounds, operating a website called HellHoundsLair.com. They perceive Sam and Dean as amateurs, although the latter use the duo and their website to help them defeat the monster of the week. At the end of the episode Sam pulls a prank on them by posing as a Hollywood producer on the phone. In the episode "Ghostfacers", they produce a television pilot, which covers their investigation of a house that is haunted every leap day, where Sam and Dean make a guest appearance; however, Sam and Dean manage to magnetically wipe their footage. The episode was nominated for a GLAAD award for its portrayal of Ghostfacers intern Alan Corbett.^[83] In "It's a Terrible Life", where the Winchesters are placed in an alternative life as office workers, Zeddmore and Spangler appear on the Ghostfacers website where they present instructional videos on how to find and to defeat ghosts, and refer to the Winchesters as rival "douchebags that we hate".^[84] Ed, Harry and the rest of the team also star in the Ghostfacers web series,^[85] a spoof advertisement which is seen in "Hammer of the Gods". They were also used as plot devices, in the season nine episode "Thinman" Ed and Harry face a conflict similar to one Sam and Dean face, creating a parallel between the characters, at the end of that episode we see an end to the Ghostfacers after Ed invents the monster Thinman to keep Harry from leaving for a normal life. Their names are homage to Winston Zeddemore and Egon Spengler, members of the Ghostbusters from the 1984 film.

Frank Devereaux, portrayed by Kevin McNally, is an expert in counterfeit documents and in avoiding government intelligence. He was first introduced in the sixth episode of the seventh season, "Slash Fiction". It is revealed in the eleventh episode, "Adventures In Babysitting", that when he was 26, his wife and two children were killed. Sometime after that, he met Bobby Singer, who once saved his life in Port Huron. Frank lives in a run-down, electronics filled house on a little traveled street. He describes himself as 'bi-polar with delusional ideation'.

Bobby sends the Winchesters to see Frank when two Leviathans begin a series of killings throughout the country, masquerading as the brothers. When Sam and Dean enter Frank's house, he is waiting in the dark with a shotgun. He is prepared to shoot them, but because he owes Bobby he agrees to help them. At first, Frank believes that Leviathan Sam and Leviathan Dean are clones created by the government. Frank advises the boys to go into hiding, maybe even move to Cuba, but Dean says they need to go "further off the grid, but keep us on the board" so they can hunt down the Leviathans. He tells them that they need to keep a lower profile, avoid security cameras, and to get rid of their rockstar aliases, which are too easy to track. He smashes Sam's laptop, gives him a new one, and demands $5000 for it. He then takes their pictures for new IDs as Tom and John Smith and gives them a map of the towns their Leviathan doppelgängers have hit so far.

In "Adventures in Babysitting", Dean gives Frank the numbers "45489" which Bobby writes on Sam's hand before he dies, and also asks him to research Dick Roman. Having not heard from him over a month, Dean returns to Frank's house to find it deserted. Frank suddenly appears, confronts Dean, and they both have to shed some blood to prove to the other they are not a Leviathan. Frank states that he has moved all his equipment into an R.V., feeling he was being watched after he started investigating Dick Roman. Frank seems paranoid about Leviathans, even thinking that Gwyneth Paltrow is one of them. He tells Dean he has found nothing on Bobby's numbers, but when he tries combinations adding a sixth number, he discovers that they are coordinates to a field in Wisconsin, owned by Dick Roman. Frank and Dean travel to the area and disguise themselves as phone company workers. They discover surveillance covering the area and retreat to Frank's RV to monitor it. They discover Amanda Willer, an employee of Dick Roman, surveying the site for construction. As they began to spy the camp field, Frank challenges Dean about how he is dealing with himself on the whole situation, even telling Dean his dark past.

In the next episodes, Dean talks with Frank off-screen. In "Out with the Old", Frank talks with Dean by phone from his camper, updating Dean on the Leviathan activity worldwide. He has no record of their activity in Portland, Oregon, where Sam and Dean are currently working, but Leviathans are there all the same. Frank discovers this when Dean asks him to investigates a company behind an odd Realtor; and the company links back to Dick Roman. Sam and Dean set out to meet Frank at the end of the episode, but instead find his RV, filled with smashed electronics and blood. In "The Girl with the Dungeons and Dragons Tattoo", it is revealed that Dick Roman took Frank's hard drive, which he gives to the IT expert Charlie to hack. When Charlie tries to hack it, the defense system uses Frank's voice. After finally hacking it, an automatic email sent to the brothers which states that if they are receiving it, it means that Frank is dead or worse. Frank has a GPS tracker on the drive and it hacks into Charlie's webcam so they know who's hacking it. While Charlie is successful, she finds out the truth about Dick Roman and the Leviathans from his files and later teams up with the Winchesters to erase the drive. Frank's final fate is still unknown.

Jessica Lee Moore, portrayed by Adrianne Palicki, is Sam's girlfriend for two years as of the start of the series. Despite this, she is unaware of his family's strange occupation. Sam planned to ask her to marry him, but she is killed by a demon on Azazel's orders; it was revealed the demon that killed her was the friend who introduced her to Sam, named Brady, to break Sam from his increasingly normal life. Her death then prompts Sam to join Dean on his quest to find their missing father and avenge her. In the days preceding her murder, Sam had had premonitions of her murder in dreams, but he ignored them as random nightmares. Afterwards, he feels guilt for dismissing them so easily. Sam eventually kills the demon that killed her and gets revenge. In an alternate timeline created by the disappearance of John Winchester in 2003, Sam mentions that he has no time for a family, suggesting that things didn't work out with Jess in that world.

Kaia Nieves, portrayed by Yadira Guevara-Prip, is a dreamwalker, a human with the ability to view alternate realities in their dreams. In Kaia's case, she is stated to be the most powerful dreamwalker her friend and mentor Derek Swan ever seen. Kaia has no control over this power and only sees a monster-filled world that she dubs The Bad Place. As is later revealed, this is because of a life-long connection to her alternate reality counterpart Dark Kaia who has in turn seen Kaia's world through their connection.

In season 13's "The Bad Place", Kaia is sought out for help by the Nephilim Jack on the suggestion of Derek Swan as Jack needs a dreamwalker to open a rift to the Apocalypse World alternate reality and rescue Mary Winchester. Jack breaks Kaia out of a drug treatment facility, but she refuses to help and runs off before being kidnapped by angels who are after Jack. Upon being rescued by the Winchesters, Kaia has to be forced at gunpoint to join them and explains that she won't help because of her fears of The Bad Place. After Jack shows Kaia Apocalypse World, she agrees to help. Cornered on an abandoned ship by angels, Kaia suggests opening the rift to escape. Combining his powers with Kaia's, Jack guides her into finding Apocalypse World instead of The Bad Place, but she begins flashing between the two worlds, ending with a vision of Dark Kaia. Jack and Kaia's efforts open a rift, destroying the attacking angels in the process, but sends the Winchesters to The Bad Place, Jack to Apocalypse World and an unconscious Kaia to a nearby roadside.

In "Wayward Sisters", Kaia is found by a passing motorist and transported to Sioux Falls General Hospital for treatment. Claire Novak, aware that the Winchesters were looking for Kaia, locates her in the hospital for help with finding her missing friends, but Kaia flees once again. However, she is attacked by a creature from The Bad Place outside and saved by Claire and Jody. Bonding with Claire over their experiences, Kaia reveals her knowledge of the creature and about the Winchesters' efforts to open a rift. The group realizes that the rift must still be open for the creature to be in their world and with Kaia's help, locates the abandoned ship where more of the creatures reside. With the rift closing, Claire chooses to crossover to The Bad Place to rescue Sam and Dean while the others stay behind to fight off the creatures. Despite her fears, Kaia crosses the rift with Claire and the two rescue Sam and Dean. As they lead the Winchesters to safety, the four are ambushed by Dark Kaia who throws her spear at Claire. Kaia saves Claire's life, but is hit with the spear in the process and apparently dies moments later. With the rift closing and a giant creature closing in on them, the Winchesters and Claire are forced to flee to their world, leaving Kaia's body behind in The Bad Place. Grief-stricken, Claire vows revenge upon Kaia's killer even if she has to find a way back to The Bad Place, unaware that Dark Kaia opened a rift of her own and crossed to their world.

In season 14's "The Scar", the Winchesters and Jody Mills hunt Kaia's killer in their world and are shocked to learn that she is Kaia's alternate counterpart. Dark Kaia admits that Kaia's death was an accident as she was aiming for Claire and displays knowledge of Kaia's interactions with the Winchesters, Dean in particular, from having seen through Kaia's eyes due to their connection. After Dark Kaia escapes again, Jody is left worried about how to explain the situation to Claire who was in love with Kaia and still seeks revenge upon her killer.

In season 15's "Galaxy Brain", Dark Kaia reveals that The Bad Place is dying and that Kaia is in fact still alive and trapped there. In a flashback, Dark Kaia is depicted treating Kaia's wound which had apparently caused her to pass out rather than die as was originally believed, before Dark Kaia abandoned her to cross to their world. With Dark Kaia having left Kaia the tools that she needed, Kaia survived two years stuck in The Bad Place, but Dark Kaia learned that her world is in trouble from the connection that still existed between the two. With the help of Jack and a Reaper named Merle, the Winchesters open another rift to The Bad Place and locate Kaia who has been living in Dark Kaia's old home. As The Bad Place is destroyed, Dark Kaia chooses to remain and die with her world as the Winchesters and Kaia escape through the rift. Reunited with Jody, Kaia accepts an invitation to return to Sioux Falls with her and is pleased to learn that Claire, out seeking Dark Kaia at the time, will be home soon.

Kelly Kline, portrayed by Courtney Ford, is the mother of Jack Kline. She was an aide to and lover of President Jefferson Rooney after the death of his wife. She first appears in "LOTUS", when Lucifer possesses the President and has sex with her, impregnating her. Crowley, realizing that a powerful nephilim has been conceived, teleports her to a motel room, where he, the Winchesters, Castiel, and Rowena explain the situation to her and try to convince her to abort the nephilim. Kelly agrees to help them lure Rooney in so they can use the Hyperbolic Pulse Generator to expel Lucifer from him. They succeed, but Kelly runs away from the motel room.

In "Family Feud", an angel sent by Heaven to get rid of the child of Lucifer finds Kelly on the run and attempts to kill her, but she is saved by Dagon, a Prince of Hell who was personally created by Lucifer. Kelly is persuaded by Dagon to accept her as her and her child's protector. In "The British Invasion", Kelly, uncomfortable with the situation, demands to see a doctor. Dagon agrees to take her, but when the doctor notices something on the sonogram, she controls him to tell her that everything is fine. Later, Sam, impersonating the doctor, tells Kelly to come back to the office. She is kidnapped by Dean, who takes her to a junkyard where Sam, Eileen Leahy, Mick Davies, and Renny Rawlings are waiting. Sam tries to explain that they just want to help her, but Dagon comes and takes her away again. In the melee, Eileen accidentally shoots Renny. Back at their hideout, Dagon handcuffs Kelly to the bed, no longer trusting her, and reveals that giving birth to a nephilim is always fatal to the mother.

In "The Future", Kelly, worried about her child being evil, attempts to kill herself, but the nephilim brings her back to life. Castiel, Kelvin, and Hozai come to the hideout to kill Kelly, but when Castiel reaches the basement he is unable to kill her. Castiel kidnaps her and takes her to a motel while he decides what to do. He decides to take her to the sandbox portal to Heaven, where Kelly and her child will die instantly but their souls will ascend to Heaven. Kelly, having seen visions from her child, now believes in its goodness. The Winchesters track them down and explain that they can extract the grace from the fetus so it will be born as a normal human being. Kelly refuses, as she believes her child has an important destiny, and drives off in the Impala with Castiel, having been told by her child that taking this path would lead to its birth. They are greeted at the sandbox by Joshua, who is then killed by Dagon. Sam and Dean arrive, and in the melee, Kelly takes Castiel's hand, lending him some of the nephilim's powers, which he uses to destroy Dagon. Castiel then takes Kelly to a safe place to give birth, having been shown by the nephilim a vision of a future paradise.

In "All Along the Watchtower", Kelly prepares for the birth of her child in a remote location with Castiel and laments that she will not be around to raise it. Kelly makes a video for her child to watch. As Kelly goes into labor, a rift into another universe opens up, and Mary Winchester comforts her through her contractions as they bond over their protectiveness of their respective sons. Kelly dies giving birth to a son, Jack.

In "Lost and Found", Jack states that Kelly is in Heaven. He recalls his connection with his mother in the womb, where he learned that Castiel was supposed to be his protector. Kelly is given a traditional Hunter's funeral. In "Patience", Jack watches the video Kelly made. In "The Big Empty", Jack shows grief counselor shapeshifter Mia the video and asks her to take his mother's form. Mia, in Kelly's form, comforts Jack and assures him he is not destined to be evil. In "Tombstone", Castiel tells Jack that Kelly would be proud of him.

In "Gods and Monsters", Jack visits his grandparents, Kelly's parents, claiming to be Kelly's friend, unable to tell them that she is dead or that he is their grandson. They show him photo albums with pictures of Kelly and remark on his resemblance to her.

During "Byzantium", Jack dies and ascends to Heaven but leaves his personal Heaven to find his mother's. Jack finds Kelly enjoying a childhood memory before approaching her and revealing his identity. Turning her back to her adult form, Kelly is greatly shocked and happy to meet him with the pair hugging. It takes Kelly a while to recall she is dead before she inquires on Jack's reasons for being present, Kelly soon realizes that he's dead too and breaks down but he comforts her that Castiel did protect him but something happened. Kelly asks what's bothering, as he explains a strange entity is chasing him. She hides her son and promises to stay by his side before Castiel arrives, having deduced Jack would be there. Castiel catches up with Kelly and soon tells them that Jack will be resurrected though part of his soul will be burned. Kelly is unsure about the idea, forcing Castiel to elaborate on the being chasing Jack, The Shadow, who wants to send him to The Empty, the resting place of angels. Kelly protects her son from the Shadow when it attacks, and witnesses Castiel make a deal with the entity to save Jack. Kelly then says goodbye to Jack, telling him to have a great life, before Castiel takes him back to Earth, resurrected. In "Moriah", Jack learns that Kelly's parents have learned that she is missing and possibly dead.

In season 15's "Destiny's Child", one of the memories that Jack experiences as his soul is restored is of talking with Kelly in Heaven. In "Inherit the Earth", after becoming the new God, Jack tells Sam and Dean that it is because of what he learned from them, Kelly, and Castiel that he is ready for his new responsibilities.

James "Jimmy" Novak, portrayed by Misha Collins, is the vessel of Castiel and a former radio ad salesman from Pontiac, Illinois. He is described by Castiel as a "devout man" who agreed to become Castiel's vessel after hearing his voice and undergoing a series of tests of faith. In "The Rapture", after Castiel is forcibly taken back to Heaven for "re-conditioning", Jimmy is left alone and found by Sam and Dean. He describes being possessed by Castiel as "being chained to a comet". He wishes to return to his family, but Sam and Dean insist that he would put them in danger from the demons hunting him down for his association with angels. Jimmy sneaks back home to reunite with his family, but he and his family are attacked by demons, and his wife Amelia and daughter Claire are kidnapped. Castiel returns and possesses Claire to vanquish the demons. Jimmy is fatally injured in the fight, and Castiel tells him he will now be at peace in Heaven. Jimmy begs Castiel to use him as a vessel instead of Claire to spare her the life of being an angel's vessel. Castiel accepts and possesses Jimmy again.

Castiel reveals to Jimmy's daughter Claire that Jimmy has been dead and his soul in Heaven, since his vessel was destroyed in his first confrontation with Raphael in "Lucifer Rising". Jimmy was reunited in Heaven with his wife Amelia after her death in "Angel Heart". In "All Along the Watchtower", Castiel uses Jimmy's name to rent a cabin for himself and Kelly Kline. After tracking the omens to the area, the Winchesters realize they have found the right spot when they learn Castiel used the name James Novak since that is his vessel. After Castiel's death in the same episode, the Winchesters give him a Hunter's Funeral by burning Jimmy's body in "Lost & Found." When Castiel is resurrected, Jimmy's body is restored to act as his vessel once again.

As seen in season 13's "Exodus", the Apocalypse World Castiel also chose his world's Jimmy as his vessel unlike most of the angels of that world who have different vessels. The Apocalypse World Castiel's version of Jimmy has a darker more scruffier appearance, coinciding with the alternate Castiel's evil nature. He also appears to be blind in one eye. This Jimmy and Castiel are killed by the Winchesters Castiel.

In season 14's "Gods and Monsters", Castiel talks about Jimmy with Lucifer's former vessel Nick. Castiel admits that while Jimmy was willing to be his vessel, he is dead, causing Nick to call Castiel a stone-cold body snatcher that is no better than Lucifer. Castiel tells Nick that in his millennia of existence, what befell Jimmy and his family is Castiel's greatest regret.

Kevin, portrayed by Osric Chau, is a Prophet of the Lord who is chosen to interpret the Word of God after Sam and Dean break it out of the slab of stone it is trapped in. He is in advanced placement and is preparing for college when he is struck by lightning and chosen. Kevin is driven to drive his mother's car to the mental institution where Castiel is and where Sam and Dean have taken the Word. He steals the Word, but Sam and Meg catch him. Castiel reveals that Kevin is a Prophet and can thus read the tablet which talks about the Leviathans.

After two angels arrive to take him away and are driven away by Dean, they take him to Rufus' Cabin where they set him to work on translating the tablet. The angels return, but after Meg kills one to save Castiel, the others allow Kevin to finish the translation before taking him home. Kevin reunites with his mother, but they discover to their horror that the detective investigating his disappearance is the Leviathan Edgar in disguise. Edgar kills the two angels accompanying Kevin and takes him and his mother prisoner.

Dick Roman later uses Kevin's mother to force Kevin to translate the tablet for him. After the Leviathans bring in a girl named Polly, Kevin manages to escape the room he's trapped in and learns of Dick's plan to poison coffee creamers to kill all the skinny people in the world, but is captured by Dick's assistant Susan before he can escape the building. During Sam, Dean and Castiel's break-in of Sucrocorp, Sam finds and rescues Kevin who reveals Dick's new plan to him and insists they need to blow up Dick's laboratory.

In the lab, they find Dean and Castiel killing Dick and Kevin is shocked when Dean and Castiel disappear when Dick explodes. Kevin nervously tells Sam they have to leave because more Leviathans will be coming, but Crowley shows up and reveals he has it taken care of and kidnaps Kevin as a prize. It is later revealed that he wants Kevin to translate another Word of God tablet so he can learn how to open all the gates of Hell and release every demon in existence upon the world. Kevin tricks Crowley and escapes, going on the run for a year before Sam and Dean catch up to him. Kevin reveals that he has learned that it is possible to seal the gates of Hell forever and banish all demons from the Earth from the tablet and Sam and Dean decide to do so with his help.

However, Crowley catches up with them and although they escape thanks to Kevin's quick thinking, Crowley murders his girlfriend in revenge. Kevin later convinces Sam and Dean to take him to see his mom who is surrounded by demons. After they rescue her, Mrs. Tran joins them in closing the gates of Hell, but they find the tablet stolen and being sold at an auction. Kevin's mom wins the auction by bidding her soul, but Crowley possesses her and gets away with the tablet. In the struggle, Dean tries to kill Crowley even though he is possessing Kevin's mother and in doing so, loses Kevin's trust. This along with the fact that Crowley warned him that the Winchesters have a habit of using people up and disposing of them when they no longer need them, causes Kevin to flee with his mother. He spends the next several episodes on the run from both Crowley and the Winchesters, but after his mother hires a witch to get the ingredients needed for the spell he used to kill the demons and escape, Crowley captures and tortures him to force him to translate the tablet. Sam, Dean and Castiel, who are alerted to his situation when Mrs. Tran calls them for help, arrive and rescue Kevin and get half of the tablet, but Crowley gets the other half and Kevin loses a finger, though Castiel is able to regrow it. They then call in Garth to look after the Trans and he takes them to his houseboat where Kevin works on translating the half of the tablet he has to no avail. Dean and Castiel later go to Kevin for help in preparing more demon bombs to rescue the angel Samandriel.

Kevin is now so focused on translating the tablet that he has somewhat let himself go and has a disheveled appearance. He has also sent his own mother away so he can work in solitude, explaining to Dean that he can't enjoy the world he is trying to save until it is saved. Though he does not believe it is possible to get the ingredients needed for the bomb as they are rare, he gives them the list and Castiel is able to get them. It is shown in "Trial and Error" that Kevin lets himself go completely while he focuses on translating the tablet, believing that closing the gates of Hell will be the only way he can go back to a normal life. Eventually, after weeks of non-stop work, he cracks the instructions and calls Sam and Dean to let them know. Kevin learns that to close the gates, someone must complete three trials and recite an Enochian spell after each one. Kevin has only cracked the first trial which is to kill a hellhound and bathe in its blood. Despite Sam's advice to slow down, Kevin begins taking stimulants to keep awake and eventually calls Sam and Dean to inform them that he has learned that hellhounds are usually invisible but can be seen through an object scorched with Holy Fire, giving them a way to see the hellhound so they can kill it. In "Taxi Driver", Kevin is under so much stress that he is hallucinating Crowley in his head and that Crowley is mentally torturing him. Panicked, he calls Sam and Dean and hides, but has also deciphered the second trial: Sam must rescue an innocent soul from Hell and release it into Heaven. After Sam leaves to rescue Bobby Singer's soul from Hell, Dean stays with Kevin, trying to calm him down. Kevin is so freaked out he hides in a closet and later hides his half of the tablet somewhere, believing it will take the pressure off of him. After Dean leaves, Kevin demon-proofs Garth's houseboat even more, but Crowley shows up and reveals he killed Kevin's mother and got his location from her smartphone. When Sam and Dean return they find the boat deserted. In "The Great Escapist", Kevin is trapped in an illusion of Garth's houseboat and is tricked into translating Crowley's half of the demon tablet by demons pretending to be Sam and Dean. At the same time, a prerecorded message Kevin prepared is sent to Sam and Dean with his notes on the tablet. While Sam and Dean do not figure out the trial from them, they eventually lead them to Metatron, the angelic scribe who wrote the Word of God. Eventually Kevin realizes the truth as the demons are too polite and sends them into a trap. Crowley confronts him and Kevin refuses to reveal more than the fact that Crowley has no idea the power he could have gotten from his half of the demon tablet and that he won't break. Not caring as he has the angel tablet, Crowley strangles Kevin who is rescued by Metatron. Metatron takes Kevin back to the hotel where he lives and heals him and Kevin reveals that he has Crowley's half of the demon tablet with him. With that half of the tablet, Kevin has learned the third trial: cure a demon. Kevin is left confused as to who Metatron is when Metatron reveals knowledge of the third trial as well. After Sam and Dean pretend to make a deal with Crowley to stop him killing people they have saved, Kevin digs up the first half of the demon tablet and reunites the two halves, giving the tablet to Sam and Dean who send him to the Men of Letters bunker for safety. When Dean and Castiel need to know the third trial to close the gates of Heaven, they take the angel tablet to Kevin who is distraught as he believed that it would be over once he was done with the demon tablet, causing an angry Castiel to yell at him that he is a Prophet until he dies. After completing the second trial, Dean calls Kevin who tells him that while he has found trials on the angel tablet, he does not see anything that matches what they have done. When Naomi shows up to tell Dean and Castiel that Metatron is really trying to expel all angels from Heaven, Kevin listens, but is unable to confirm what she has said. He later tries to leave the bunker, but stops when alarms start going off, signaling the fall of all angels to Earth.

After the angels fall, Kevin is left trapped in the bunker as it locks down and he panics, nearly shooting Dean with a crossbow when he arrives. Kevin is not happy to see that the Winchesters have Crowley captive and have not killed him. Kevin is put to work trying to find a way to reverse Metatron's spell using the angel tablet. When Dean calls Kevin to get him to confirm their cover at a military base, Kevin succeeds by hacking into the person he is talking to's computer and blackmailing them. He later gets a call from Abaddon and passes on her message to Sam and Dean and at their request, looks through the archives for a way to kill a Knight of Hell. Crowley, who is in a dungeon in the next room, taunts Kevin, causing Kevin to beat him with a sledgehammer. Crowley then claims that he never killed Kevin's mother and will lead Kevin to her if he releases him and that the Winchesters are just using him. While Kevin does not release Crowley, he decides to leave and look for his mother but is stopped by Dean who convinces him that his mother is as good as dead even if she is still alive. Dean tells him that the Winchesters consider both him and Castiel to be family and would die to protect him if need be. Kevin aids Sam and Dean with finding a spell to communicate with animals and is later asked by Dean to find a way to suppress an angel. Kevin finds a way, but is murdered by Gadreel possessing Sam soon afterwards on Metatron's orders. Dean burns his body in a Hunter's Funeral afterwards and is devastated by and blames himself for Kevin's death. A month after his death, Kevin returns as a ghost, having been stuck in the veil between worlds due to Heaven being closed. Kevin asks Sam and Dean to rescue his mother who he has learned from another ghost named Candy is still alive. With Candy's help, Sam and Dean track down Linda who tearfully reunites with Kevin. Despite the risks, Linda decides to take the ring Kevin is attached to and look after him until he can enter Heaven. Kevin similarly wants to look after his mother now that he has her back. Kevin informs Sam that he does not blame him for his death, aware that it was really Gadreel and asks Sam and Dean to put aside their differences and start being brothers again before leaving.

Two years later in "All in the Family", Kevin's ghost is called in by God in the form of Chuck Shurley to reassure the Winchesters that they can trust Him. The Winchesters are shocked to see Kevin who tells them that they can trust Chuck and that whatever He has planned for them, He must believe they can do it. Kevin tells the Winchesters that he's fine for someone who is dead before Chuck tells Kevin that he has been stuck in the veil between life and death for too long. With a wave of His hand, Chuck causes Kevin's soul to ascend to its rightful place in Heaven.

In season 15's "Raising Hell", Kevin unexpectedly returns to help Dean and Arthur Ketch against the souls God released from Hell. Kevin explains that God lied about sending him to Heaven and instead cast Kevin's soul into Hell where he was released when God opened all the doors of Hell. Due to being cast into Hell by God himself, Kevin's reputation allows him to push around the other souls and he attempts to help in the plan to trap the souls. However, Francis Tumblety, also known as Jack the Ripper, learned from demons about Kevin's connection to the Winchesters and the ghosts turn against him. After a failed attempt to use Kevin as leverage, the escaped ghosts, aside from Kevin, are trapped in a crystal by Rowena. Afterwards, having learned from Belphegor that being cast into Hell means he can never get into Heaven, Kevin requests to be released from the barrier so that he can wander the Earth as a ghost. Though being an untethered ghost means he might eventually go crazy, Kevin prefers that fate to returning to an eternity of torture in Hell. After a final goodbye with the Winchesters, Kevin leaves through a doorway Belphegor opens in the barrier and vanishes to wander the world.

Lisa Braeden, portrayed by Cindy Sampson, is a woman Dean spent a weekend with around 1999. In the third-season episode "The Kids Are Alright", Dean decides to visit Lisa and he discovers she has an eight-year-old son named Ben who shares his cocky attitude and love of classic rock. After Ben is kidnapped by a changeling who committed the murders, Dean rescues Ben. She returns in season three when Deans sees her in his dream in "Dream a Little Dream of Me"

She also makes a brief appearance at the end of Season 5, Episode 17, where Dean visits her.

She returns again in season six, where her and Dean are in a relationship. Her memory is eventually wiped by Castiel toward the end of the season, since Dean wants her away from the hunting lifestyle.

Michael "Mick" Davies is an operative from the British Men of Letters, portrayed by Adam Fergus. When he was a young boy, Mick was orphaned and spent some time living on the streets. In an attempt to get some money, he picked the pocket of a member of the British Men of Letters and accidentally stole a cursed coin. The British Men of Letters saw potential within Mick and sent him to the Kendricks School. At the Kendricks Academy, Mick was best friends with a boy named Timothy. He was also classmates with Arthur Ketch who called them "survivors" when describing their experience years later.

One day in 1987, Mick and Timothy were pulled into the office of Doctor Hess, the Headmistress and one of the British Men of Letters Elders. To ensure they would follow the code absolutely, Doctor Hess left them a knife and told them only one of them could leave the room alive. While Timothy wanted to run, Mick reluctantly killed his best friend, per the code. This event would haunt him for the rest of his life.

In "Season 12, Mamma Mia", Mick comes to America to return Toni Bevell to London, where she'll face consequences after establishing that she's gone way off her original mission, which was to identify American hunters and gain their trust.

He first discovers Ms. Watt's corpse and calls Toni to inform her of his intentions, calling her a "bad girl". After Toni has a face-off with Mary Winchester, Mick arrives with Castiel at her location. He insists that he and the British Men of Letters wish to work with the Winchesters and he even gives them his number, but they don't trust him.

In the car, he tells Toni that she must fly back to London, and that Mr. Ketch, whom he's already called, will take it from here.

In "LOTUS", Sam calls Mick for help with Lucifer but hangs up when he gets Mick's voicemail. Realizing that the Winchesters are likely in trouble, Mick sends Arthur Ketch to help them, resulting in Arthur rescuing them from the Secret Service and supplying them with a device capable of exorcising Lucifer.

In "First Blood", Mick is shown using a typewriter to discuss some of the events that were occurring in the episode. He is writing to his superiors, and he mainly talks about the Winchesters and American hunters in general. He is first shown trying to convince a hunter named Wally to work for the British Men of Letters. Wally's rejection leads Mick to remark that American hunters are "difficult". He then talks about Sam and Dean, who managed to escape Site 94, but they left survivors behind. He then remarks that it is Arthur Ketch's purpose to clean up "loose ends". He describes how Arthur took over Site 94 before the Government decided to shut it down completely. Lastly, Mick is shown talking to Mary Winchester, offering her the same things he offered Wally, but Mary shows interest instead.

In "The Raid", Mick leads an operation with several American hunters to wipe out all of the vampires in America. Within a month, Mick's operation wipes out two hundred and thirty of the two hundred and forty one vampires in the Midwest. After Mary gets Sam to check out his operation, Mick shows him around and includes him in a briefing of their planned attack on the final vampire nest in the Midwest.

Shortly afterwards, the compound comes under attack by vampires and Mick is shocked to learn that the Alpha Vampire is behind it as the British Men of Letters intel places him in Morocco for at least a decade. Mick is further shocked when Sam admits to having seen the Alpha Vampire in Hoople, North Dakota five years before. When Mary calls for everyone to show any weapons they possess, Mick has nothing useful and admits to having never taken a life before. While discussing options for taking down the Alpha Vampire, Mary has Mick show Sam the Colt, the one weapon the British Men of Letters possess capable of harming the Alpha. Sam is able to provide Mick with a ritual created by Bobby Singer to make more bullets for the Colt and Mick performs it moments before the Alpha Vampire breaks in and kills two hunters.

After killing the two hunters, the Alpha Vampire announces his intention to force Mick to contact his superiors and tell them the mission failed before draining Mick on camera. Before he can follow through on his threat, Sam and Mary return and Sam arms himself with the empty Colt. As Sam negotiates with the Alpha Vampire, Mick discreetly shows him the bullet for the Colt he has palmed and then attacks Sam in apparent anger after Sam offers Mick up to the Alpha Vampire in exchange for the safety of himself and his family. In reality, Mick slips Sam the Colt bullet which he loads thanks to a distraction from Mary. As Mick and Mary watch, Sam kills the Alpha Vampire with the Colt.

Following the battle, Mick berates Arthur Ketch who had been trying to recruit Dean in his own way and was thus away during the battle. Sam tells Mick that he is now in as despite everything that went wrong, they kill the Alpha Vampire and Mick's operation is making the world a better place.

In "Somewhere Between Heaven and Hell", Mick sends Sam text messages with cases for the Winchesters to take. As Mick calls him at the end of the episode, Sam admits the truth to Dean who decides to give Mick a chance.

In "Ladies Drink Free", Mick brings the Winchesters a werewolf case and asks to accompany them to get actual experience in the field. Though reluctant, Dean agrees to take Mick along. While the Winchesters talk to victim Hayden Foster's mother, Mick disguises himself as a doctor and examines her wounds, discovering that she has been bitten. Mick lies to the Winchesters about it and returns that night to kill Hayden with a silver nitrate injection as per British Men of Letters protocol, something he is visibly reluctant to do. After Hayden awakens and attacks him, clawing open Mick's shoulder, Mick uses the silver nitrate injection to kill her.

The next day, Mick joins the Winchesters in investigating Hayden's "mysterious" death, seeming conflicted by his actions. He later accompanies Dean to a bar to interrogate Hayden's boyfriend with his behavior drawing Dean's suspicions. Dean realizes that Mick murdered Hayden and is enraged by his actions since Hayden was an innocent sixteen-year-old girl and as a pureblood werewolf, could have controlled herself.

After Claire Novak is bitten, Mick advocates killing her while Sam wants to try a cure the British Men of Letters invented involving injecting the newly turned werewolf with the blood of their sire. As the Winchesters go to track down Claire's sire, they leave Mick with Claire, warning him that if he kills her, they will kill Mick. As Claire starts to turn, she begs Mick to kill her, believing that she cannot control herself. However, while Mick admits that all of his instincts are telling him to do it, he's starting to understand that his instincts are wrong and instead plans to tie up and sedate Claire. They are then attacked by Claire's sire, Justin, who kidnaps Claire and knocks Mick unconscious.

The Winchesters return to find Claire gone and Mick waking up. Mick tells them that they can track Claire as he slipped a tracking device into her coat. Finding Justin's home through Mick's tracking device, Mick and Sam attack Justin with Mick jabbing Justin in the back with a syringe to get his blood. However, they are both quickly thrown off and Justin attacks Dean. Before Justin can kill Dean, Mick kills Justin with a silver bullet to the heart from behind. Mick then removes the vial of blood from Justin's back and uses it to cure Claire. The next morning, the Winchesters thank Mick for giving them a win and give him a second chance as a result. Mick is amazed by Claire's survival and curing and calls her a miracle to which Dean agrees with him.

In "The British Invasion", Mick is haunted by memories of murdering his best friend Timothy as a child and visits the Men of Letters bunker where he spends all night drinking with the Winchesters after learning about Lucifer's child. The next morning, Mick receives word from Doctor Hess that they don't have time to convince the American hunters to join them and orders Mick to "assimilate or eliminate" them and sends her lackey Renny Rawlings to keep an eye on him.

Mick and Renny join the Winchesters' attempt to capture Kelly Kline. While initially successful, Dagon shows up, shrugs off all of their attacks and escapes. Eileen Leahy tries to kill Dagon with the Colt, but she teleports away, causing the bullet to kill Renny. Mick initially tries to kill Eileen per the British Men of Letters code, but Sam convinces Mick to follow his own code instead and he orders them to go. Later, Mick returns to his headquarters to find Arthur Ketch and Doctor Hess. Having learned his lesson from working with the Winchesters, Mick defends the Winchesters way of doing things as opposed to the British Men of Letters code. Mick tells Doctor Hess that their code would have a young boy murder his best friend but he's no longer a boy, he's a man now. In response, Doctor Hess signals Arthur who shoots Mick in the back of the head at point-blank range with a silenced pistol, killing him. Standing over Mick's body, Doctor Hess announces that the experiment with the American hunters is a failure and they are going to kill the Winchesters now.

In "The Memory Remains", Arthur sends the Winchesters an email posing as Mick to send them on a case to get them out of the bunker. He poses as Mick again later in a text message to check that they are in fact gone. When the Winchesters call Mick to check in, Arthur answers and claims that Mick was recalled to London and "has a lot to answer for" after what happened with Dagon so they will now report to him.

In "Twigs & Twine & Tasha Banes", Mary starts to get suspicious about Mick's disappearance as he hasn't responded to her phone calls or emails for weeks. Afterwards, Mary gets an email from "Mick" claiming that he is to remain in London for a few more weeks. Hearing Arthur talking about a package in the armory, Mary checks it out and discovers a box containing Mick's body, upsetting Mary. After finding Mick's body and finding information on hunters being chased by the British Men of Letters, Mary confronts Arthur who claims he was killed by a werewolf. However, Mary quickly realizes that Arthur is lying and in fact killed Mick himself since he was shot in the head which a werewolf is unlikely to do.

In "There's Something About Mary", after learning of the British Men of Letters attack on American hunters, the Winchesters capture Lady Toni Bevell for answers. When they question what Mick thinks about it, Toni reveals that Mick is dead, much to their obvious shock and grief as the Winchesters had genuinely liked Mick.

Missouri Moseley, portrayed by Loretta Devine, is a very talented psychic residing in Lawrence, Kansas. She was a long-time friend of John Winchester. Missouri first met John on December 17, 1983, when he came to her for a reading. She said it was 'a few days after' Mary was murdered. Missouri said she was the one who opened his eyes to 'what was in the dark.' John took Missouri to his house, hoping she could tell him what killed Mary. Unfortunately, Missouri could not tell what it was, just that it was "real evil". Twelve years later, Missouri returns in season 13's "Patience." Missouri, who is revealed to also be a former hunter, contacts the Winchesters for help when a monster targeting psychics kills her protégé. Missouri helps Dean and Jody Mills determine that they are dealing with a Wraith and she receives a premonition of her own death. Missouri sends Dean and Jody away to protect her granddaughter Patience Turner, who is also a powerful psychic and allows the Wraith to kill her, having seen that this is the path that will ensure its destruction. With help from Patience, Dean kills the Wraith and avenges Missouri's death while also fulfilling her last wish to see her granddaughter protected. In the process, Patience learns that her father lied to her for most of her life about her grandmother.

Nick, portrayed by Mark Pellegrino, is a widower and Lucifer's primary and most well known vessel. Though Nick himself only initially appears in person in season 5's "Sympathy for the Devil", he plays a major role from seasons five to thirteen as Lucifer's vessel. He subsequently joins the main cast in season 14 after the death of Lucifer.

In season 5's "Sympathy for the Devil", Nick, who has recently lost his wife Sarah and son Teddy in a brutal home invasion, is tormented by visions created by Lucifer regarding the loss of his family. Lucifer, appearing in the form of Nick's dead wife, approaches Nick openly eventually and asks for Nick's permission to take Nick as his vessel. Though Lucifer can't bring back Nick's family, he offers Nick the chance to get revenge against God and explains his version of why God threw Lucifer out of Heaven. Nick ultimately consents to becoming Lucifer's vessel.

Subsequently, Nick appears throughout season 5 as Lucifer's vessel. In "Free to Be You and Me", Lucifer visits Sam in Nick's form and explains that Sam is actually Lucifer's one true vessel. Nick was just a backup plan and can barely contain Lucifer without spontaneously combusting which is not a problem that Lucifer would face with Sam. As a result of Lucifer's sheer power, Nick's body slowly degrades over season 5 as Lucifer's power burns him out and he develops ever worsening skin lesions. Several characters note the state of Nick's body over the course of the season with Castiel stating in "Two Minutes to Midnight" that Lucifer has to drink gallons of demon blood just to keep it intact at all. In "Swan Song", after Sam says yes to Lucifer, he abandons Nick's body for Sam's. Nick is left dead on the ground, completely burned out from containing Lucifer for nearly a year.

In season 7, Sam's hallucinations of Lucifer take on the form of Nick. In season 11's "O Brother, Where Art Thou?" and "The Devil in the Details", Lucifer manifests in Hell to communicate with Sam. In "Hell's Angel", despite having Castiel as his vessel at the time, Lucifer takes on Nick's form in Castiel's mind to battle Crowley when he tries to get Castiel to expel Lucifer. When Lucifer is yanked out of Castiel's body in "We Happy Few" by the Darkness, an image of Nick is briefly overlaid over Castiel as Lucifer is expelled.

In season 12's "Stuck in the Middle (With You)" and "Family Feud", Lucifer is revealed to be imprisoned in Nick's body rather than the Cage after he was exorcised from the President of the United States in "LOTUS." In "Family Feud", Crowley explains to Lucifer that his demons found Nick's body a few years before and Crowley had it repaired and upgraded so that it could serve as the perfect vessel and perfect prison for the archangel who was sent into Nick when Crowley perverted Rowena's spell to send him back to the Cage. Crowley's improvements keep Nick's body from degrading again and he remains a sound vessel for Lucifer without fear of burning out like Lucifer's previous vessels aside from Sam did. Although Crowley installs a security system in Nick's body to control Lucifer, it is reversed upon Crowley with the help of Drexel in "There's Something About Mary" and Lucifer gains full control over his vessel. After his escape, Doctor Hess shows Sam surveillance photos of Lucifer on the loose again in "Who We Are" and Sam believes her as he recognizes Lucifer's old vessel.

Throughout the second half of season 12 and all of season 13, Nick acts as Lucifer's permanent vessel. Lucifer is eventually killed by Dean in "Let the Good Times Roll", leaving Nick's body lying on the floor of a church surrounded by the burned impressions of Lucifer's wings.

In season 14's "Stranger in a Strange Land", Nick is revealed to still be alive, living in a makeshift bedroom in the Men of Letters bunker's dungeon. Sam speculates that as the archangel blade is designed to kill the archangel inside and not the vessel, it left Nick unharmed aside from a slowly healing wound in his side where he was stabbed. Nick has nightmares of his time under Lucifer's control and Sam and Mary Winchester have a hard time looking at him due to his long possession by Lucifer and thus his resemblance to him. Nick is able to remember that Michael told Lucifer that he wanted to "do it right this time", but can't provide Sam with any more useful information than that on Michael's plans.

In "Gods and Monsters", Nick is visited by Castiel in his room where Nick experiences flashbacks of the things Lucifer forced him to do. Castiel reminds Nick that it was the murder of Nick's family that caused Nick to consent to Lucifer's possession, causing Nick to experience flashbacks of how Lucifer tortured him to get Nick to say "yes". Nick digs into the murder of his family and discovers that the case has never been solved in all the years since the murder, enraging him. As Nick displays uncharacteristically aggressive and Lucifer-like behavior, Castiel determines that though Lucifer is gone, he may have done more damage to Nick's psyche than they realized. In an attempt to solve his family's murders and get revenge, Nick visits his old neighbor Arty who was a witness to a man running out of his house the night of the murders, but subsequently changed his story. Believing someone to have gotten to Arty, Nick attacks him and demands to know the truth. Nick later bashes Arty's head in with a hammer, the same way his family was murdered. In "The Scar", Castiel tells Sam and the returned Dean that Nick took off claiming that he had personal matters to attend to and hasn't been returning Castiel's phone calls since.

In "Unhuman Nature", Nick continues his bloody quest for revenge, torturing a priest whom Arty had confessed to and then brutally murdering him when the priest refuses to break his vows and tell Nick what he knows. Nick then meets with the reporter who covered his family's murders in hopes of learning something useful. At Nick's request, the reporter reveals that a man named Frank Kellogg was the beat cop in Nick's neighborhood at the time of the murders. Nick is subsequently tempted to murder a prostitute, but stops himself. Nick tracks down and tortures Frank, having learned from Arty that he had seen a cop running out of Nick's house at the time of the murder and then been threatened by the police into silence. Frank finally reveals that he responded to a 911 call from Nick's wife reporting a prowler only to meet a man named Abraxas outside of Nick's house and then wake up in his police cruiser covered in Sarah's blood. Nick realizes that Abraxas was a demon who possessed Frank to murder Nick's family. Even though Nick acknowledges that the murders weren't Frank's fault, he still beats the man to death with a hammer regardless as Frank's hands were used to butcher his wife and son. In the aftermath, Nick prays to Lucifer, having realized that he enjoyed the freedom that came with expressing his inner darkness and is now missing the fallen archangel. In the Empty, a skeletal figure rises with glowing red eyes, presumably Lucifer awakened by Nick's prayer.

In "Damaged Goods", Nick continues his revenge quest by capturing and torturing demons to find Abraxas. Nick finally learns that Abraxas was captured by Mary Winchester while he was slaughtering a Girl Scout troop and sets out to Hibbing, Minnesota to find Mary. Nick's behavior alarms a local grocery store clerk who calls local Sheriff Donna Hanscum who discovers that the van Nick is driving is stolen while his fingerprints show Nick as being wanted for his murder spree. Nick subdues Donna and tracks Mary down through Donna's phone, kidnapping Mary who admits that she locked Abraxas in an Enochian puzzle box when she couldn't defeat him. Nick forces Mary to lead him to the storage unit where Abraxas is located and kidnaps a security guard to act as Abraxas' vessel. Nick frees Abraxas who offers him answers in exchange for Nick murdering Mary. Before he can, Nick is confronted by the Winchesters who tracked him down with Donna's help. Nick breaks the devil's trap and Abraxas attacks before revealing that he murdered Nick's family on Lucifer's orders and that Nick was chosen, although for no special reason. While Abraxas is distracted by Dean, Nick kills him with an angel blade to avenge his wife and son and is then subdued by Donna and Mary. Nick is arrested by Donna for his murder spree and justifies his actions as necessary to get revenge. Sam apologizes for not being able to save Nick or his victims, who will haunt Nick for the rest of his life.

In "Prophet and Loss", Nick escapes after brutally beating up a cop and returns to his old house where he encounters the ghost of his wife Sarah. Even though Nick has gotten her revenge by killing Abraxas, Sarah can't rest due to Nick's inability to give up Lucifer. Unable to give Lucifer up even for Sarah, Nick departs to continue his search for the archangel.

In "Game Night", Nick kidnaps the prophet Donatello Redfield and claims to have injected him with thallium. Nick resists the Winchesters' attempts to get him to reveal Donatello's location and enjoys taunting them. Finally, he agrees to lead them to Donatello while Jack discovers that Nick injected Donatello with angel grace, not poison. Nick explains that he used Donatello as a conduit to communicate with Lucifer in the Empty and intends to bring him back. Nick bashes Sam's head in with a rock, leaving him severely injured, before fleeing to an abandoned cabin to perform a spell Lucifer gave him using Jack's blood. Nick succeeds in bringing Lucifer back from the Empty, but is interrupted by Jack and Mary. Jack sends Lucifer back to the Empty and causes Nick to burn up from the inside, killing him before healing Sam's injuries. Nick's body is later found by Sam and Dean in "Absence." Sam covers up Nick's body with a blanket, but it is apparently otherwise just left in the abandoned cabin. Despite wanting Nick dead, Sam is horrified by the brutal manner of his demise.

In season 15's "Inherit the Earth", a resurrected Lucifer returns in the form of Nick. However, it's unclear if Nick was resurrected as well. When Lucifer is killed for a second time by Michael, he explodes into ash, leaving nothing of Nick behind.

Pamela Barnes, portrayed by Traci Dinwiddie, is a friend of Bobby Singer. A skilled psychic, she is bold and aggressive. Bobby calls upon her assistance in discovering what pulled Dean Winchester out of Hell in season 4. She holds a seance and discovers it is a being named Castiel. In attempting to get a glimpse of Castiel, her eyes are burnt out and she becomes permanently blind. However, her psychic abilities appear to enable her to perceive her surroundings. The Winchesters again seek her assistance in finding out why Anna Milton can hear angels speak. She expresses an interest in "dicking over" angels because one caused the loss of her sight. She places Anna under hypnosis, which restores to Anna her memories of being an angel. She is called upon one more time by the Winchesters, to help them perform astral projections of themselves. While doing so, she is mortally wounded by a demon, but as her dying act, whispers a warning to Sam to stop using the demonic forces within him. In season 5's "Dark Side of the Moon", the Winchester brothers encounter Pamela in Heaven, who is happy residing in her own private paradise.

Pamela reappears in season 14's "Nihilism" where, in the world Michael created for Dean in his mind, he owns a bar with Pamela and is happy, experiencing a looped existence. When Sam and Castiel enter Dean's mind, they are surprised to find Pamela present and after they remind Dean of her blindness and death respectively, Pamela becomes blind and then disappears, having only been a construct of Dean's imagination.

Lady Antonia "Toni" Bevell, portrayed by Elizabeth Blackmore, is a Woman of Letters from British Men of Letters.

In "Season 11, Alpha and Omega", Toni returns to her home in London only to get a call that something bad is happening. She heads to her basement where she observes a bulletin board decorated with information on the Winchester family.

She bids her sleeping son goodbye and prepares to head out. Her servant gives her a few weapons before she leaves.

When Sam and Castiel return to the Bunker after the sun was restored to normal, she uses the angel banishing sigil on Castiel and tells Sam that she is a member of the British Men of Letters. When she asks about Dean, Sam tells her he's dead.

Toni tells Sam that she has come to take him to see the Boss at the London Chapter of the Men of Letters. She accuses him of playing with things - Archangels, Leviathans, the Darkness - bigger than he can handle. She soon fires a gun at him, leaving Sam's fate uncertain.

In "Season 12, Keep Calm and Carry On", Toni brings Sam, who she shot in the leg, to Dr. Marion to have his injuries treated, paying him with $100,000 to not ask questions. Taking him to a farmhouse, Toni explains that the British Men of Letters have kept Britain safe from monsters for forty years and want to do the same with America. To this end, she demands information on all of the hunters in America, their leadership and how to contact them. When Sam refuses to tell her, Toni has Ms. Watt torture him for the information, but he continues to refuse. Though Ms. Watt suggests bringing in Mr. Ketch, Toni refuses as she doesn't like the man and instead decides to resort to mental torture, causing Sam to have hallucinations of dead people in an attempt to break his mind. However, when Dean calls her and threatens Toni if she doesn't turn over Sam, she sends Ms. Watt to kill him. Eventually, Sam apparently commits suicide as a result of his hallucinations, but in actuality tricks Toni and briefly overpowers her. Sam nearly escapes, but Toni manages to lock him in the basement once again.

In "Mamma Mia", Toni uses a spell and potion to create a hallucination where she seduces Sam to get information from him. She is unable to get much before Sam sees through it and Toni resumes her physical torture. As she tortures Sam, Toni gets a call from Mick informing her that Ms. Watt is dead and he has come to bring her in as she's gone too far. Toni refuses to stop and captures Dean when he locates the farmhouse with help from Ms. Watt's cell phone and Castiel. Toni threatens to torture Dean instead but before she can begin, a resurrected Mary Winchester threatens her at gunpoint. Toni and Mary engage in a fight that ends with Toni cutting open her hand and mentally strangling Mary while Dean threatens her with Mary's gun. Toni demands the gun, stating Mary will die if she is killed and Dean pretends to comply. As Dean hands over the gun, he punches Toni unconscious, having recognized that she was using a Chinese mind control technique and that knocking her out would end its effects.

The group is then interrupted by Mick who explains that Toni's orders were to make contact with the Winchesters but she went too far out of her belief of their being a malfeasance in the American hunters. Mick promises that Toni will be punished in London for her actions and departs with her. Toni remains steadfast in her desire to get answers, but Mick refuses though he tells her if necessary, he will do what he has to do to deal with the situation. To that end, he has called for Mr. Ketch, something that leaves Toni visibly uneasy.

In "The Raid", Arthur Ketch has a drink with Dean and tells him that Toni's rogue actions were unforeseen by all but Arthur who "had a sneak peek at what a neurotic, overreaching time bomb she was". Arthur then explains that he and Toni used to date which Dean is not surprised by.

In "Twigs & Twine & Tasha Banes" and "There's Something About Mary", Toni returns to brainwash Mary into being a remorseless killer for the British Men of Letters. Toni succeeds, but is lured into a trap and captured by the Winchesters. Toni informs them of Mick Davies' murder and confirms that her organization is likely responsible for the death of American hunters. At the bunker, the Winchesters are ambushed by Arthur Ketch and three operatives. After killing Arthur's men, a brainwashed Mary forces them to let Arthur go. Arthur then locks the Winchesters in the bunker, initiating a lockdown that cuts off all power, water and air which will result in their suffocation in two to three days. As Toni is a rival for heading the American operation, Arthur locks her in the bunker to die with the Winchesters.

In "Who We Are" Toni claims that she is the only person that can undo Mary's brainwashing to get the Winchesters to spare her. For two days, the Winchesters and Toni work together to find a way out with a magical solution ultimately failing. As the three are on the verge of dying, Dean uses a grenade launcher to blast a hole into the sewers, a plan that Toni feels is insane. Dean then hits the bunker's manual override and save Sam and Toni.

After learning that Jody Mills has captured Mary, the Winchesters demand that Toni break the brainwashing and she finally admits to lying to them about being able to do it. Toni suggests the Winchesters run and watches Sam's rallying speech to the American hunters with apparent interest. Toni agrees to help Dean enter Mary's mind using equipment at the bunker and asks in return that Dean give her a head start before killing Toni so that she can have a chance to see her son one last time. With Toni's help, Dean breaks Mary's brainwashing, but awakens to find that Arthur Ketch has murdered Toni while he was unconscious.

Doctor Hess, portrayed by Gillian Barber, is a British Men of Letters Elder and the Headmistress of the Kendricks Academy.

In 1987, Doctor Hess forced Kendricks student Mick Davies to murder his best friend Timothy as a test of Mick's loyalty to the British Men of Letters code.

In "The British Invasion", Doctor Hess contacts Mick and orders him to "assimilate or eliminate" the American hunters. To ensure Mick's compliance, Doctor Hess sends her lackey Renny Rawlings to watch over him. Following the accidental death of Renny at the hands of Eileen Leahy and the Colt, Doctor Hess personally comes to the British Men of Letters compound, leaving Britain for apparently the first time. After determining that Mick has become too much like the American hunters, Doctor Hess has Arthur Ketch murder him and announces that they will now wipe out the American hunters, particularly the Winchesters.

In "There's Something About Mary" and "Who We Are", Doctor Hess personally coordinates an operation to wipe out the American hunters. She suggests to both Arthur Ketch and Lady Toni Bevell that once it is over, she will place each of them in charge.

As her operatives prepare to strike against the hunters, their families and any bystanders, an assault team of American hunters led by Sam Winchester attacks the British compound. Despite being heavily outnumbered and outgunned, the American hunters slaughter the British operatives, taking some casualties of their own. Desperate, Doctor Hess kills a hunter and retreats to the control room to call for extraction, but the people in Britain can't get her out. She is then confronted at gunpoint by Sam, Jody Mills and another hunter named Walt. Doctor Hess attempts to convince Sam that they still need each other as Lucifer has escaped and Crowley is dead. After a moment of consideration, Sam refuses Doctor Hess' offer and pointedly destroys the computer she was using to communicate with Britain. Enraged, Doctor Hess attempts to shoot Sam only to be shot through the head herself by Jody Mills. The American hunters then destroy the British compound, ending their operation and threat in America.

In "All Along the Watchtower", Sam shares the intelligence Doctor Hess gave him on Lucifer with Dean and Mary. Sam is shown to believe Doctor Hess' claims as he recognizes Lucifer's vessel from the surveillance pictures Doctor Hess shared with him.

Victor Henriksen, played by Charles Malik Whitfield, was an FBI agent who pursued the Winchesters since the bank "robbery" in the season two episode "Nightshifter". He believed the Winchesters were serial killers responsible for the deaths that have occurred in various towns. He continued to pursue them when, in the season three episode "Jus in Bello", he finally captured them and held them in a small town jail while waiting for an FBI helicopter to arrive. However, demons arrived and destroyed the helicopter; one of them possessed Henriksen but was exorcised. Finally believing in the supernatural, he agreed to help the Winchesters as they fought off the demon horde. Afterwards, he agreed to tell the FBI that they were in the helicopter when it crashed. However, after the Winchesters left, he was killed by Lilith. Henriksen made another appearance in season four's "Are You There, God? It's Me...Dean Winchester". Lilith was breaking the 66 Seals to free Lucifer, and one of them was the Rising of the Witnesses. Sam, Dean, and Bobby met the ghosts of people they could not save, including Henriksen, who told them what happened after they left the jail at the end of "Jus in Bello". The ghosts terrorized the trio until they were put to rest.

Chuck Shurley, also known by the pseudonym Carver Edlund and portrayed by Rob Benedict, is an author of a marginalized book series Supernatural, which recounts everything the Winchester brothers have experienced during the show's run. After confronting him about his seemingly omniscient knowledge of their escapades, it is revealed that he is a Prophet of the Lord, and his works will become new gospels. Between the fourth-season finale "Lucifer Rising" and the fifth-season premiere "Sympathy for the Devil", he witnesses the death of Castiel at the hands of the archangel Raphael. Being the author of the Supernatural series, he attends the first Supernatural convention Sam and Dean were tricked into attending. When it turns out the hotel is actually haunted, he is forced to occupy the guests and the hotel staff while the Winchesters and a pair of cosplayers destroy the ghosts. When the hotel manager leaves and breaks the salt line, he dissipates the ghost with an iron post, unintentionally gaining the affections of Becky.

In "Swan Song", Chuck is periodically narrating about the history of the Impala, his script having the same name as the episode. He informs Dean of the final battlefield between Michael and Lucifer, despite the angels wishing him not to know. At its conclusion, while ending the narration, Chuck smiles and disappears into thin air, leading some to question whether he is merely a prophet that is no longer needed or is actually God.^[86][87][88] Castiel later states that while he doesn't know what happened to Chuck, he must be dead as a new Prophet was chosen in the form of Kevin Tran and that only happens when the old Prophet dies.

In the Season 10 episode "Fan Fiction" Chuck is shown to be alive as he reappears at the end of a play based on his books and comments that it was "not bad" when asked his opinion by the play's writer, Marie.

In the Season 11 episode "Don't Call Me Shurley", Metatron is transported to a bar that he recognizes as one of God's constructs where he meets with Chuck. After Metatron criticizes his writing, Chuck reveals to the shocked Metatron that he is in fact God, having taken on the form of Chuck Shurley to have a more hands-on role. God explains that after the Apocalypse was averted, He traveled the world but has grown tired of everything and intends to let Amara destroy the world while He works on His autobiography with Metatron's help. God gives Metatron several insights into His actions, confirming He resurrected Castiel several times to aid the Winchesters and revealing he "turned off" Dean's amulet's ability to detect him. He also shows sympathy for Lucifer, stating that Lucifer is not a villain. God is generally apathetic to what's going on on Earth, but Metatron gives Him an impassioned speech about how humanity is better than Him because for all their flaws, they still try. After finishing his autobiography, God has Metatron read it while he plays "Dink's Song" on his guitar. On Earth, God stops Amara's insanity infection and resurrects those who died because of it. After finding Dean's old amulet glowing in Sam's pocket, the brothers follow it to the middle of the street where God, in the form of Chuck, is helping those affected by Amara. The Winchesters are shocked to realize that Chuck was God the whole time and God tells them they should talk.

In "All in the Family", God proves who he is by transporting the Winchesters to the bunker and calling upon the spirit of Kevin Tran to confirm his story. The Winchesters then learn from Metatron that God intends to sacrifice himself to the Darkness to save the universe rather than fight her. After the Winchesters rescue Lucifer, God greets his rebellious son for the first time in millennia and heals his numerous injuries from Amara's torture. In "We Happy Few" there is great tension between God and Lucifer, but the Winchesters get them to have a sit-down in which God admits Lucifer was always his favorite and he feels he failed him by giving him the Mark. Lucifer and God reconcile and gather the witches, angels and demons to aid them in battling Amara since Raphael was dead, Gabriel was presumed dead, God couldn't bring them back in time, and Michael is insane. Together, they defeat the Darkness and God goes to transfer the Mark to Sam to imprison his sister once more, but the Darkness retaliates, leaving God mortally wounded. In "Alpha and Omega", God reluctantly aids the Winchesters in formulating a plan to kill the Darkness to balance the scales once he's dead. As God grows weaker and the universe dies with him, the Darkness teleports him to her location where Dean has convinced her to find another way. The Darkness admits she was jealous of no longer being everything to God and asks to have her brother back. The siblings reconcile and the Darkness heals the injuries she inflicted upon God, reversing the end of the universe. The two siblings then depart the Earth together for a "family meeting".

Chuck/God later appears in the season 14 finale "Moriah", where he tries to convince the Winchesters that Jack Kline has become too powerful and needs to be stopped. After much persuading, God manages to get the Winchesters on his side. However, As Dean prepares to execute Jack with the Colt, Sam realizes that God is enjoying the scene. The Winchesters and Castiel then discover that their entire lives have been nothing more than stories for Chuck/God's sadistic amusement. When the Winchesters confront him on his manipulations (culminating in Dean telling him to "go to Hell"), God responds by killing Jack himself. As he prepares to leave, Chuck is shot and wounded by Sam, causing him to declare "The end" of their story, unleash the souls of hell and leave.

Weakened by the Colt, Chuck seeks help from Amara in Reno. Amara, however, realizes that Chuck has never changed as a person, and leaves him trapped on earth. Chuck then meets with Becky, and tells her of his "ending" to the story of the Winchesters. When Becky is horrified by his idea, Chuck reveals himself to be God before presumably killing her and her family.

God later traps Sam and Eileen in a casino, whose occupants he murdered. Knowing that Dean and Castiel are working to defeat him, Chuck shows Sam visions of the "future" if they win. In it, Castiel is corrupted by the Mark of Cain, and the Winchesters are eventually turned into monsters and killed by Bobby Singer and Jody Mills. Broken by these visions, Sam does not help his brother and Castiel kill God when they arrive. Chuck then manages to heal himself, before revealing that the visions were actually from other worlds. He then departs, leaving the Winchesters, Castiel, and Eileen in the casino.

God/Chuck later enters a store in another world, where he reveals himself as being a sociopathicnarcissist who sees the Winchesters as "toys" that exist for his amusement. He then decides to annihilate all the other universes he created. As the clerk begs for his world to be spared, Chuck tells him that "everything will be alright". Chuck then proceeds to destroy the other earth as well.

Having eliminated the other worlds, God returns to the main world, where he meets with Amara. God explains his view of humans as "boring" creatures who "ruin everything they touch". After much debating, Amara traps her brother in the Winchesters' bunker, having previously agreed to help them defeat him. As Dean brings Jack, who is intended to be a bomb, to the bunker, Sam arrives, revealing that their plan will result in Billie, the current "death", to take Chuck's place. Chuck then reveals that he organized the entire event to pit the brothers against each other. Dean tries to ignore Sam's warnings, going as far as threatening to shoot him, before calming down. Chuck then reveals that the Winchesters intend to kill Amara as well, causing her to give in and let him absorb her and her powers. Infuriated that the Winchesters have again defied him, God declares that he is done with them, and leaves after wounding Jack.

In "Inherit the Earth", the Winchesters discover that God has killed all other life on the planet. In a bid of desperation, they contact him, and offer to kill each other in exchange for Chuck bringing back everything else. Chuck, however, reveals that he has decided to let them suffer in a lifeless world. He later sadistically kills a dog the Winchesters found. God then revives his son Lucifer, and sends him to steal his "deathbook" from the Winchesters. Lucifer, however, is killed by his brother Michael, who has since sided with the Winchesters.

Michael later betrays the Winchesters and summons God in an attempt to become his "favorite" again. God, however, executes Michael for his earlier betrayal. He then reveals to the Winchesters that he now intends to "cancel" their "show" and begins savagely beating them. The Winchesters, despite serious injuries, begin to laugh, much to Chuck's confusion. Jack then ambushes Chuck and drains him of all his power. The Winchesters reveal that Jack has been able to harness the energy from Lucifer, Michael, and now God by watching their fights. Chuck accepts his defeat and prepares to be killed, only for the Winchesters to reveal that they instead have chosen to let him live as a mortal and die forgotten. The Winchesters and Jack then leave a horrified Chuck alone in the woods, though his ultimate fate is left alone.

In The Winchesters, it's revealed that God had created the Akrida as a failsafe in case of his defeat: monsters that threatened to finish what God had started and destroy all of creation, including the Multiverse which Jack had restored following God's defeat. Breaking Jack's rules about no interference, Dean guides alternate reality versions of his parents and their friends to destroy the Akrida, foiling God's plan once and for all. Although God himself doesn't appear in The Winchesters, Rob Benedict makes a cameo appearance as a band member named Tango in one episode.

Jack Kline, portrayed by Alexander Calvert, is a Nephilim and the son of Lucifer and Kelly Kline. He is the first and only known Nephilim to be sired by an Archangel. Jack was trained by Sam and Dean Winchester to master his powers. During this time, Jack played a crucial role in the resurrection of Castiel, whom he had chosen as his father figure.

Jack journeyed to Apocalypse World to rescue Mary Winchester and fought against Michael's angel army to protect a human colony. He helped Mary consolidate human survivor groups to form a resistance.

Jack's resistance fought in many conflicts. with Jack frequently turning the tide, gaining him the respect of many leaders. Later, he reunited with Sam, Dean, and Castiel, also meeting Lucifer and Gabriel. Lucifer tempted Jack to join him, playing the victim. Gabriel, Castiel, and the Winchesters reminded Jack of Lucifer's history, although Jack began to believe Lucifer and hoped they could defeat Michael. However, the Winchesters stranded Lucifer during the evacuation of the resistance.

Lucifer later offered to take Jack to the stars on a father-son journey. Jack at first accepted, but after discovering that Lucifer agreed with Michael to abandon the earth so that it could be destroyed, Jack disowned him. In retaliation, Lucifer attacked Jack and stole his grace to defeat Michael, then kidnapping Jack and Sam. Lucifer attempted to force Jack and Sam to kill each other, but the pair were rescued by Dean (empowered by Alternate Michael).

After Lucifer's death, Jack struggled with life as a human; taking lessons on hunting and magic from the humans and Castiel, secretly hiding an illness that stems from his lack of grace and his body attacking itself. Succumbing to his illness, he ascends to Heaven where he meets his mother for the first time. He is pursued by the Empty's ruler Shadow who attempts to bring him to his domain. Castiel intervenes and Jack is resurrected with Enochian magic. Confronting Michael, he taps into the power of his soul and kills Michael, absorbing the Archangel's grace to regain his Nephilim powers. However, he burned off much of his soul in the process. It Is eventually revealed that Jack had sacrificed his entire soul to kill Michael, becoming completely soulless.

In "Moriah", God provides the Winchesters with a gun that can kill Jack, though it will also kill the shooter—ostensibly due to the danger Jack poses. Enraged at the loss of his mother, Dean confronts Jack in a cemetery where he has been meeting Castiel. Rather than fight, Jack accepts that losing his soul had made him a monster and orders Dean to kill him. However, Dean cannot bring himself to act, enraging God, who appeared before them. God wanted Jack dead at Dean's hands because for Jack's father to kill Jack would make add to his story. Dean rejects God's offer to resurrect Mary, knowing that Mary would not object. The Winchesters and Castiel turn against God, leading God to smite Jack with a snap of his fingers and begin the end of the world. As the souls of Hell rise, Jack awakens in the Empty where he is greeted by Shadow and Billie. Jack's corpse was used as a vessel by the demon Belphegor to help the Winchesters after he escapes from Hell. However, Castiel smote Belphegor after learning that the demon intended to use the Winchesters to gain power for himself. This second smiting burnt Jack's corpse into a charred skeleton which was apparently left on the floor of Lilith's Chamber in Hell when Castiel had to climb out before the rupture between Earth and Hell closed.

In the Season 15 episode "The Trap", Jack is revealed to still be awake in the Empty. As he looks around the realm, Billie appears to tell Jack that "it's time".

In "The Gamblers", a resurrected Jack is discovered by Castiel to be hunting Grigori, fallen angels who feed on innocents' souls. After killing the Grigori, Jack eats their hearts to grow stronger, but refuses to use his powers as it will draw God's attention to him and reveal his resurrection. Castiel rescues Jack from the last of the Grigori and Jack reunites with his family. Jack explains that Billie had hidden him in the Empty until God left Earth, at which point it was safe for Billie to resurrect him. Billie provided Jack with a plan that will allow Jack to become strong enough to kill God.

In "Galaxy Brain", Jack is revealed to still be soulless, worrying the Winchesters. After learning that Kaia is alive and trapped in the Bad Place from Dark Kaia, the Winchesters attempt to find a way back without Jack's powers. Jack views Kaia through Dark Kaia's mind and decides to risk helping his friend. With the reluctant help of reaper Merle, assigned by Billie to watch over Jack, the Winchesters and Castiel temporarily hide Jack's use of powers from God, allowing him to open a rift to the Bad Place. After Kaia's rescue, Billie kills Merle for failing to keep Jack in line and explains that everyone has a book in Death's library detailing their fate, even God. The book describing God's ultimate destruction mentions Jack, Sam and Dean, though Billie refuses to elaborate further.

In "Destiny's Child", the Winchesters discuss the ramifications of Jack killing God and consider having him kill the Darkness as well to maintain the balance. After encountering an alternate Sam and Dean, Billie arrives to warn that God is almost done destroying alternate universes and will soon return to their world. Billie presents another quest for Jack, stating that the first was to strengthen his body, while the second is more spiritual. Billie instructs them to find the Occultum, though she does not know where it is and refuses to explain its purpose. While the Winchesters talk to Anael, Jack speaks with Castiel about his soul and how he cannot feel emotion, which bothers him. Jack questions whether Dean will ever forgive him. Castiel advises patience. Castiel has Jack drain most of his life force so that Castiel can travel into the Empty and question Ruby. Jack reluctantly complies, but brings Castiel back on Sam and Dean's orders. Having learned the Occultum's location, Castiel leads the others to a church guarded by hellhounds where they uncover a small orb. Swallowing the orb, Jack is transported to the Garden of Eden where he is confronted by a mysterious young girl and Snake. Snake asks who Jack is and who he is meant to be, leading Jack to experience flashes of his life and collapse in tears. Jack returns to the church and kills the hellhounds. Sam and Dean later find him in the bunker's kitchen, crying with remorse and horror over killing Mary. Castiel reveals that the Occultum restored Jack's lost soul.

During "Last Holiday" and "Gimme Shelter", Jack deals with the return of his soul and helps the Winchesters without using his powers. He also confided in Castiel that the plan to defeat God requires him to becomes a supernova that will destroy God and Amara.

In "Unity", team Free Will was able to recruit Amara and make a plan to defeat God, who has destroyed the multiverse. Jack meets Amara, his great-aunt.

In "Inherit The Earth", Jack and Sam reunite with Dean who informs them that God had eradicated humanity and that both Castiel and Bobby were in the Empty. God allowed them to survive, so they could live out their lives, albeit alone. As they bemoan their fate, Jack is revealed to have suffered aftereffects of the explosion, as wither and die after he walked past them. The group discovers Michael is alive and enlists his aid but he is unable to read God's death book. Jack is horrified to be reunited with his resurrected father who kidnaps a reaper to have her take Billie's place to find a way to defeat God, but this is revealed to be a ploy as Lucifer kills the reaper and is on God's side. He tries to recruit Jack but before he can answer, Michael kills Lucifer. The group soon hatch a plan and confront God, though Michael betrays them and is then killed by God. When God decided to personally end the Winchesters, they attack but are left bloodied. The Winchesters then reveal Jack, who is unaffected by God's attempt to smite him. Jack grabs his grandfather, stripping him of his powers. After they are healed, Sam and Dean explain that after Jack exploded in the Empty, he became a power vacuum. The brothers notice the flower's lifeforce being absorbed. The battles between Lucifer and Michael restore Jack's powers and they hatch a plan to fool Michael into betraying them and allowing themselves to get beat on, so that God would expose Jack to his powers, explaining his immunity. Chuck applauds their efforts and expects death, though team Free Will decide that a more fitting punishment for him is to live a mortal life, eventually aging and dying whilst forgotten by humanity. Jack confirms that Chuck will never reacquire his divine powers, ending his threat. Once in town, Jack restores all who were erased by Chuck, while making sure they don't recall their deaths. Jack then leaves the Winchesters explaining that he and Amara are in sync and his powers allow him to be everywhere. He decides not to be hands-on like his grandfather and that as the new God he will live up to the examples that his family (the Winchesters, Castiel, and his mother) taught him.

During "Carry On", Bobby Singer reveals to Dean in Heaven that Jack had become the new Ruler of Heaven, released Bobby, and tore down its walls, allowing souls to freely interact without reliving past memories. It is also revealed that Jack has resurrected Castiel from the Empty in order to help reshape heaven. It is mentioned that Jack was not present at the moment, but Bobby remarks Jack made Heaven the way it should be.^[89]

In the series finale, Jack appears in the Monster Club's universe with Singer to admonish Dean for breaking Jack's rule on direct interference. It is revealed that Jack had restored the Multiverse. However, Dean points out that the Akrida (Chuck's failsafe) were a threat to their world as well as Sam. With Bobby backing Dean, Jack acknowledges that another case always appears for hunters, even after death, and he allows Dean to finish his work by returning Dean's journal and Colt to him. This allows Dean to pass on the journal and weapon to John and Mary, so they can avoid the Apocalypse to live a peaceful life and better prepare for supernatural. After Dean says goodbye to his parents, Jack vanishes with Dean, Bobby and the Impala in a flash of light.

The Darkness, often called by her other name Amara, and portrayed primarily by Emily Swallow, is a supremely powerful primordial entity who has existed since before the beginning of time, along with her twin brother God. She is described as the darkness that existed before Creation. God created the Archangels to fight a terrible war against her. Through the combined power of God and the Archangels, God sealed her away, not wanting to kill her, by using the Mark of Cain as both a lock and key. God revealed that he chose not to kill her in her weakened state as they both needed to be alive because light cannot exist without darkness, and killing Amara would disrupt the balance that reality is founded upon, destroying it. The Archangels battled her and thus knew of her existence, but she is so ancient and mysterious that the Demons and the Angels, besides the Archangels and Metatron, God's scribe, did not believe she existed. During the eleventh season, she escapes her prison to get revenge on her brother, but she and God reconcile by the end of the season.

In season 15, Amara returns, enjoying a peaceful life on Earth and wanting nothing to do with her brother and his plans to destroy everything. The Winchesters discover that to kill Chuck, they must also kill Amara to avoid the universe coming to an end. After learning that Dean has betrayed her, Amara allows Chuck to absorb her so that they can once again become one. However, she is still alive somewhere within Chuck. After Jack absorbs Chuck's power and becomes the new God, he tells the Winchesters that he and Amara exist in harmony.

Death, portrayed by Julian Richings, is an immensely powerful entity also called The Grim Reaper or the Pale Horseman. He is neither demon nor angel, and states he is "as old as God."

In the climax of "Abandon All Hope", Lucifer performs a bloody ritual to raise Death, and to bind him to Lucifer's apocalyptic bidding. In "Dead Men Don't Wear Plaid", Death goes to Bobby's hometown of Sioux Falls and resurrects many deceased locals as undead; this includes Bobby's wife. The revived at first appear and act normal, but soon take on feral states; this forces others to kill them in self-preservation. These events were an attempt to break Bobby, one of the few remaining influences keeping Sam from agreeing to be Lucifer's vessel. In "The Devil You Know", Bobby temporarily sells his soul to Crowley to locate Death. In "Two Minutes to Midnight" — Death's first corporeal appearance — Death arrives in Chicago to precipitate a storm which would kill three million. His vehicle is a pale white 1959 Cadillac. In a lengthy conversation with Dean, he reveals that this and other actions is the influence of Lucifer's binding spell, which Death wishes to break. He presents Dean with his ring, the final piece allowing the Winchesters to open Lucifer's cage and re-imprison Lucifer. "Two Minutes to Midnight" also introduces Death's taste for the typical, renowned, and often unhealthy local restaurant foods of the places he visits, which becomes something of a running gag.

Death appears again in "Appointment in Samarra", in which Dean attempts to convince him to retrieve Sam's soul from Lucifer's cage. Death agrees to do so if Dean performs Death's duties for an uninterrupted 24 hours. Although Dean fails, the Horseman still restores Sam's soul, regarding the Winchesters as "useful". He also forms a wall between Sam's active consciousness and the debilitating memories of his time in Lucifer's cage.

In season seven when Castiel proclaims himself God, the Winchesters summon and bind Death as part of a plan to stop Castiel; Death takes an instant dislike to him. He informs the angel that he is not God and that he is harboring something else within him, the Leviathans, that will soon break free. Castiel removes the Winchesters' bind and leaves. Death, of his own free will, creates another eclipse, giving the Winchesters and Castiel a chance to return the souls to Purgatory before they destroy his vessel. Castiel succeeds in sending the souls back, but the Leviathans manage to hold on and escape into the world.

In "I Think I'm Gonna Like It Here", when Sam is dying, Death comes to reap him personally, intimating that he considers it an honor. He also states that, though he usually does not pass judgment, he finds all Sam's actions "well-played". Sam requests, and Death agrees, to make it so that Sam dies permanently, such that no one and nothing can bring him back to life. Ezekiel, in Dean's form, interrupts them, however, and Death allows them to talk, saying that it is Sam's choice if he lives or dies. Sam chooses to live, ultimately, and Ezekiel possesses him to heal the damage the trials inflicted.

In "Brother's Keeper", Dean summons Death to kill him as he feels the Mark of Cain is corrupting him too much and he cannot fight it anymore. Death is unable to kill Dean because of the Mark's power and explains that the Mark was created to lock away an evil primordial entity known as the Darkness after God and the Archangels defeated it in a terrible war and that transferring the Mark to someone else is necessary to keep the Darkness bound. When Dean refuses to do this, he offers to transport Dean so far away he is no threat to anyone. However, he demands Sam's death in return as he fears Sam will try to rescue Dean and will not give up until he succeeds. Believing it to be for the greater good, Dean agrees and calls Sam to their location. Death tells Sam his reasons for wanting him dead, including Sam escaping him earlier. Death watches as Sam and Dean argue and fight and then Sam agrees to sacrifice himself to stop the threat of the Mark and the Darkness. Death gives Dean his scythe to do the job and tells him that if Dean does not kill Sam, he will. However, after being reminded of how good he really is and his love for his family, Dean instead impales Death with the scythe, killing him. Death can only stare at Dean in shock before crumbling to ash, leaving Dean stunned that he actually killed Death.

In "Out of the Darkness, Into the Fire", while talking with the Darkness, Dean mentions having learned about her from Death. The Darkness is confused by his statement, telling Dean that she does not know Death and he does not know her.

In "Form and Void", a Reaper named Billie confirms to Sam that Dean did kill Death. Billie states that while Death was amused by the Winchesters' cycle of death and resurrection, there is now a single rule: "what lives, dies". As a result, when the Winchesters eventually die, Billie will toss them into "the Empty" where nothing ever returns from to ensure they will remain dead.

In "Advanced Thanatology", Billie appears as the new Death. Billie reveals that one of the rules of the Universe is that when one incarnation of Death dies, it is replaced by the next Reaper who dies first. Having been killed by Castiel in "First Blood", Billie is now the new Death with her own ring and scythe and a new perspective on life and death. Billie continues this role until "Despair" when she is killed. Billie is briefly replaced as the new Death by Betty before Betty is killed by Lucifer.

Eve, portrayed by Julia Maxwell and Samantha Smith, is also known as the "Mother of All". Eve was last on Earth 10,000 years ago. She is the original propagator of the majority of supernatural beings. She has been trapped in Purgatory, where the souls of the supernatural go. Eve is released from Purgatory in "Like a Virgin" by a sacrificial ritual. In "...And Then There Were None", Eve creates a being - referred to colloquially as the Khan Worm - that can enter a person's body through the ear and control their actions. She plants it inside a trucker, who goes on to kill his family. It then passes to one of his co-workers who kills 12 people. While investigating the murders, it infects Dean who kills his cousin Gwen, and then infects Samuel, and finally Bobby who kills Rufus while possessed. While possessing Bobby, it tells Dean and Sam that it was created by Eve, who intends for supernatural beings to take over the world. After acquiring the ashes of a Phoenix, said to be lethal to Eve, Sam, Dean, Bobby and Castiel take the fight to her in "Mommy Dearest". Eve reveals that her actions are purely a response to Crowley, still alive, and his capture and torture of her children. She speculates that he is after the souls in Purgatory, and claims that she was satisfied with the natural order of humans and monsters coexisting (with occasional bloodshed on both sides) until Crowley forced her hand. Eve dies after biting Dean, who had Phoenix ash in his blood, to which Crowley takes her body for autopsy. In "There Will Be Blood!", when the Leviathan Edgar is very dismissive towards the Alpha Vampire, he calls himself a "son of Eve", but Edgar calls the Alpha a "mutt" and Eve was "barely worth being called one of us". When Edgar calls Eve a whore, the Alpha Vampire is enraged and attacks him. Though Eve does not appear herself, when Dean and Castiel return to Purgatory to seek out a 'Leviathan Blossom' for a spell to be used against God, Eve sends some Leviathans after them to capture Castiel, still angered at his role in taking the souls of Purgatory. However, Cas escapes with one of the Blossoms before he can be brought to her.

Pestilence, portrayed by Matt Frewer, is one of the Four Horsemen of the Apocalypse, along with War, Famine and Death. He wears an emerald-embedded ring. He can create and manipulate infestations, plagues, diseases, and other sicknesses.

Upon Lucifer's rise, Pestilence spreads Swine Flu on Earth. It is later revealed that the flu was spread to distribute the Croatoan Virus in the form of a 'vaccine'. Dean witnesses the effects of this when transported to the future by Zachariah - approximately 90% of the planet's population is infected. When the Winchesters track Pestilence, he is revealed to be vengeful for the defeat of War and Famine. Castiel defeats the Horseman by removing his ring and, with assistance from Crowley, the spread of the Croatoan Virus is prevented. The eventual fate of Pestilence is unknown, but it can be assumed that he survived his defeat, albeit much weakened.

The Shadow, portrayed by Misha Collins, Erica Cerra and Rachel Miner, is the mysterious and powerful being inhabiting the Empty. Called the Shadow by Naomi, it is also referred to as a cosmic entity and the Empty itself by various characters.

In season 13's "The Big Empty", the Shadow is awoken when Castiel unexpectedly wakes up in the Empty. Taking on the form of Castiel himself but with a more sinister voice, the Shadow explains that it and the Empty predate everything and that not even God has power in its realm. It attempts to torment and threaten Castiel into compliance, but he continually refuses and demands that it resurrect him instead. After Castiel threatens to keep it awake for eternity until they both go insane, the Shadow reluctantly resurrects the angel. In "Tombstone", Castiel briefly mentions annoying "an ancient cosmic being" into sending him back to life, but subsequently attributes his resurrection to Jack.

In season 14's "Byzantium", the Shadow invades Heaven in search of Jack after the young Nephilim dies, feeling that he belongs in the Empty due to his half angel nature. The Shadow demonstrates its immense power by effortlessly blasting into Heaven, blowing open even the gates permanently sealed by Metatron years earlier and consuming the remaining angels. Secretly possessing the angel Dumah, the Shadow accompanies Castiel to Jack in Kelly Kline's Heaven where it reveals itself and attempts to take Jack with it. Receiving a prayer from Dean that they are ready to resurrect Jack, Castiel offers to trade himself for Jack to the Shadow, pointing out that it could be waiting eons for him otherwise. The Shadow accepts the deal, but warns that it will come to collect when Castiel is truly happy. The Shadow departs Dumah and Heaven and returns to the Empty, restoring all of the angels to normal.

In "Moriah", after being killed by God, Jack awakens in the Empty where he is greeted by the Shadow in its viscous humanoid form. The Shadow forms a smile on its face and appears to laugh at the confused Jack before Billie appears to tell Jack that they need to talk.

In season 15's "Destiny's Child", the Shadow takes on the form of Meg Masters when Castiel returns to the Empty in search of Ruby. Imitating many of the demon's mannerisms, the Shadow greets Castiel with Meg's trademark "Hello, Clarence", but is unable to collect on their deal as Castiel is not truly happy and it is working with Billie to stop God, having allowed Billie to resurrect Jack. Though annoyed, the Shadow reluctantly allows Castiel to converse with Ruby to find out the location of the Occultum. When Castiel prepares to leave, the Shadow explains that Billie has promised to send it back to sleep in exchange for the Shadow's help, something that the entity has been unable to do on its own since Castiel and Jack inadvertently woke it up two years before. Though the Shadow can't collect on their deal yet, it enjoys torturing Castiel while he is still within its power. After Jack takes Castiel out of the Empty, the amused Shadow simply comments that it will see him soon.

In "Unity", the Shadow, still in the form of Meg, is discovered by Sam inside of Death's Library searching for Billie. The Shadow explains that Castiel's visit to the Empty caused the being to doubt Billie's trustworthiness. To Sam's shock and horror, the Shadow reveals that Billie's true plan is to take power as the new God once Jack kills Amara and Chuck, leaving a power vacuum. For its help, Billie has promised to help the Shadow return to its slumber. Though the Shadow has located Chuck's book in the library, only Billie can read it. Sam convinces the Shadow that he is working for Billie and the being reluctantly turns the book over to him. During this time, its revealed that the Shadow can't come to Earth unless it is directly summoned there due to precautions put into place by Chuck.

In "Despair", to contain Jack's detonation, Billie teleports him into the Empty where he encounters the Shadow, still using Meg's form. The being is at first amused by his appearance until Jack explodes, engulfing them both. Both Jack and the Shadow survive, but after the being reforms, it is noticeably horrified and tells Jack that he made the usually silent Empty "loud", indicating that something has gone terribly wrong. At the same time, Billie confirms that the Shadow was telling the truth about her plans and that she really did lie to and manipulate the being. However, she feels safe on Earth as the Shadow can't come unless it is directly summoned. Billie eventually rescues Jack from the Empty after Sam returns Chuck's Death book, angering the Shadow who was causing Jack intense pain at the time. After being mortally wounded with her own scythe by Dean, Billie returns to her library which she has warded against the Shadow as a precaution. Later, Castiel realizes that the only way to stop Billie is to complete his deal with the Shadow which will summon it to take him. Castiel reveals his deal with the Shadow to Dean and completes it by confessing his love for Dean. The Shadow immediately opens a portal into the Empty in the bunker's dungeon and sends through two tendrils of darkness which absorb Castiel and Billie and pull them into the Empty.

In "Carry On", Bobby Singer reveals that Jack resurrected Castiel from the Empty again, freeing Castiel from the Shadow's clutches.

Deities are god-like beings of different cultures that are also known as pagan gods. The deities were powerful beings many years ago, gaining power from their human followers as well as from human sacrifices. Due to the arrival of the Abrahamic religions, many deities were weakened, resulting in them having to take human sacrifices themselves. Many deities act on their own accord, gathering power or human sacrifices for themselves.

In season one, Sam and Dean encounter the Vanir (performed by Mike Carpenter) in the episode "Scarecrow" where one of them appears as a scarecrow.

In season three, Sam and Dean encounter Madge and Edward Carrigan (portrayed by Merrilyn Gann and Spencer Garrett) in "A Very Supernatural Christmas" where they are pagan gods of the winter solstice from an unspecified culture.

In season five, Sam and Dean encounter a Leshi in "Fallen Idols" who assumes the form of Abraham Lincoln (portrayed by David Livingston), Mahatma Gandhi (portrayed by Paul Statman), and Paris Hilton. The episode "Hammer of the Gods" features the pagan gods Kali (portrayed by Rekha Sharma), Baldur (portrayed by Adam Croasdell), Mercury (portrayed by John Emmet Tracy), Odin (portrayed by Duncan Fraser), Ganesha (portrayed by Keith Dallas), Baron Samedi (portrayed by Precious Silburne), Zao Shen (portrayed by King Lau), Isis, and two unnamed pagan gods who hold a meeting at the Elysium Motel which they create while making a meal out of any human who checks in. Mercury poses as the desk clerk who does most of the creation of the Elysium Hotel, Isis poses as a waitress, and Zhao Shen is implied to work as the hotel chef due to him mostly being in the kitchen. Their meeting is to discuss what to do about the threat of Lucifer and the approaching apocalypse. Gabriel infiltrates the meeting passing himself off as Loki up to the point where Kali remembers him. Sam and Dean warn them that Lucifer will overwhelm them. The pagan gods are persuaded to release the remaining humans. When Lucifer arrives at the Elysium Motel upon being summoned by Mercury, he kills Mercury and the pagan gods until only Kali remains. She is evacuated by Sam and Dean while Gabriel fights Lucifer.

In season six, Sam and Dean encounter Veritas (portrayed by Serinda Swan) in "You Can't Handle the Truth."

In season seven, Sam and Dean encounter Osiris (portrayed by Faran Tahir) in "Defending Your Life." In "Time After Time", Sam and Dean encounter Chronos (portrayed by Jason Dohring).

In season eight, Sam and Dean encounter Plutus (portrayed by Gerard Plunkett) and Vili (portrayed by Alex Daikun) in "What's Up, Tiger Mommy?" while Plutus' assistant Beau (portrayed by Jonathan Walker) was exclusive to this show. The episode "Remember the Titans" had Sam and Dean encountering Zeus (portrayed by John Novak) and Artemis (portrayed by Anna Van Hooft) who were hunting Prometheus.

In season nine, Sam and Dean encounter Vesta (portrayed by Lindy Booth) in "Rock and a Hard Place."

In season ten, Sam and Dean encounter Calliope (portrayed by Hannah Levien) in "Fan Fiction" where she was interfering with a play adapted from Chuck Shurley's book by manifesting a copy of the Vanir's scarecrow form.

In season twelve, Sam and Dean encounter Moloch (portrayed by John DeSantis) in "The Memory Remains."

In season thirteen, Sam and Dean encounter Yokoth and Glythur in "The Thing" where they came from another reality. Both of them were killed by God. The episode "Unfinished Business" featured the real Loki (portrayed by Richard Speight Jr.) who had a history with Gabriel where he freed Loki from his imprisonment that Odin placed him in. Loki later double-crossed him and then went after Gabriel years later to exact revenge for what Lucifer did to Odin. Gabriel was able to slay Loki.

In season fourteen, Sam and Dean encounter Anubis (portrayed by Sean Amsing) in "Byzantium" who worked in Heaven and heard their tales.

In season fifteen, Sam and Dean encounter Fortuna (portrayed by Lynda Boyd) and her demigod son Pax (portrayed by Stephen Huszar) in "The Gamblers" where they learned the history of the pagan gods from Fortuna. It is revealed that God created the deities so humanity can blame them for his mistakes and that they also can make great stories.

Djinn are a race of monsters appearing in Supernatural. Unlike common lore, they do not actually grant wishes, and instead put their victims into a dream-state where they play out a fantasy in their mind where their wish has come true while the djinn feeds off of them. Other djinn have shown the ability to instead place their victims in a sort of waking nightmare state where they hallucinate their worst fears before being killed. A bastard offshoot exists as well, feeding on fear instead of desire and instead of putting people into states where they imagine their greatest desire, they are put into a nightmare where they experience their worst fear. Both kinds of djinn, the regular djinn and the bastard offshoot can be killed by a silver knife dipped in lamb's blood. Regular djinn poison can be cured using an antidote developed by the Campbell family, but the antidote does not work on the bastard offshoot's poison. This is speculated to be because they are a different kind of djinn and need a different kind of antidote. Another way of saving a person under the influence of djinn poison is to wake them from their dream state which breaks the loop they are in and ends the effects of the poison.

In season 2's "What Is and What Should Never Be", the Winchesters hunt a djinn who apparently grants Dean's wish that his mother never died. As a result, Dean awakens in what is apparently an alternate reality where Mary Winchester is still alive, John Winchester died of natural causes years before, Sam is engaged to Jessica Moore and Dean is somewhat detached from his family though he has a beautiful girlfriend named Carmen Porter. While originally happy, Dean is distressed by his distance from his family and the discovery that the people the Winchesters saved died in the alternate reality without Sam and Dean there to save him. He is also haunted by visions of a young woman he found hanging in the djinn's lair. Dean decides to track down the djinn and reverse his wish, accompanied by a reluctant Sam. Upon arriving at the djinn's lair, Dean comes to the realization that he is not in an alternate reality after all but instead is in dream state while the djinn feeds on him. Despite his imagined family trying to convince him to stop, Dean commits suicide in the dream which awakens him in the real world where Sam finds him. Dean kills the djinn as it tries to put Sam into a similar state and they rescue the young woman, the djinn's other victim, who survives.

In the season 6 premiere "Exile on Main St.", Dean is targeted for revenge by three djinn a year after quitting hunting in revenge for the death of the djinn in "What Is and What Should Never Be" who they identify as their father. Posing as Dean's waitress, one of the djinn, Brigitta, poisons Dean who experiences intense hallucinations, ending with an attack by the long-dead Azazel. Dean is saved by Sam who injects Dean with an antidote. Sam, who Dean was unaware was still alive, explains that he was targeted by the djinn too and was saved by the Campbell family. To draw Dean out, the djinn attack and kill his neighbors then give him a "double dose" of poison, destroying the antidote. Sam manages to bash in the head of one of the male djinn with a golf club while the other is killed from behind by Samuel Campbell with a silver knife dipped in lamb's blood. Brigitta is captured by Samuel and Christian Campbell and taken to Crowley who tortures her for information on the Alpha Djinn. Brigitta is found by the Winchesters, Castiel and Meg Masters in "Caged Heat" where she begs them for help. Brigitta is killed by Castiel when he destroys the monster prison.

In season 8's "Pac-Man Fever", the Winchesters and Charlie Bradbury investigate a case of people who die with their insides turned to jelly and a strange blue handprint on their arm. Dean discovers from John Winchester's journal that the culprit is a bastard offshoot of djinn who are revealed to feed on fear rather than desire. The local coroner, Jennifer O'Brien, is revealed to be a djinn who has been using her job to cover up her murders for years by immediately cremating the bodies. Jennifer kidnaps Charlie and places her into a nightmare state where Charlie has to fight off an endless army of monsters to protect patients in a hospital, particularly her brain dead mother who losing is Charlie's greatest fear. Jennifer is found out by the Winchesters and killed by Dean. Unable to wake Charlie with the djinn antidote, Dean uses African dream root to enter her dream state where he manages to get her to let go of her fear and wake up. At the same time, Sam discovers that the most recent murders were committed by Jennifer's teenage son. Unaware of how to hide his kills and having just come of age, he drew too much attention with his actions. Despite being in a weakened state from the Hell Trials, Sam manages to kill the boy.

In season 9's "Bloodlines", djinn are revealed to be one of the Five Monster Families of Chicago. According to shapeshifter David Lassiter, the djinn control the South Side. A representative of the family meets with werewolf Julian Duval to forge an alliance in preparation for a possible war with the shapeshifter Lassiter family following the murder of family head Sal Lassiter by an insane hunter.

In season 13's "Scoobynatural", Castiel returns to the Men of Letters bunker with fruit from the Tree of Life. Castiel reveals that the Tree was guarded by a pack of djinn, most of whom Castiel killed before negotiating with the rest. Castiel notes that he thinks he is now technically married to the djinn queen.

In season 14's "Nightmare Logic", the Winchesters, their mother, Bobby Singer and another hunter named Maggie encounter a djinn named Neil who has been enhanced by Michael. Michael's enhancements allow Neil to tell a person's worst fears simply by touching them and bring the fears to life around them. Neil puts a home owner named Patrick Rawling into a coma, apparently as the result of a stroke and poses as Patrick's live-in nurse. While investigating the case, Dean recognizes the rig Neil is using to drain the home owner's blood as the same he was hooked up to by a djinn in "What Is and What Should Never Be" and confronts Neil who reveals that he was left as a trap for hunters by Michael while he was possessing Dean, resulting in Neil mistaking Dean for Michael when he arrived. After revealing that Michael has left similar traps all over, Neil attacks Dean who mysteriously proves immune to his powers. Lacking a silver knife dipped in lamb's blood, Dean bashes Neil's head in with a heavy metal bookend, killing him and then fires several more shots into his head, ending Neil's manifestations. As Neil's poison was what was keeping Patrick comatose, he recovers as well once Neil is dead and he is no longer under Neil's influence. Taking Neil's warning to heart, the Winchesters spread the word to other hunters about Michael's traps.

Ghosts are one of the most recurring monsters of the week on Supernatural, appearing at least once each season.

In the show, there are several different types of ghosts that appear including:

• Death Omens - The Death Omens are an indicator where a person that is visited by it is going to die. They can manifest in different places at once. Isaiah Merchant (portrayed by Linden Banks) from "Provenance" was the first Death Omen that appeared after he was killed by his adoptive daughter Melanie.
• Vengeful Spirits - The ghosts of people who want revenge for a wrong committed to them in life. Mary Worthington (portrayed by Jovanna Burke) from "Bloody Mary" was the first vengeful spirit they encountered where she was originally killed by a surgeon named Trevor Sampson and was based on Bloody Mary.
• Violent Spirits - A type of dangerous ghost motivated by cruelty.
• Women in White - Female ghosts in white clothes that kidnap men and children and are loosely based on La Llorona. Constance Welch (portrayed by Sarah Shahi in the pilot, Shanae Tomasevich in "Moriah" and season 15) is a known Woman in White who drowned her children in a bathtub after finding her husband Joseph cheating on her and committed suicide. She haunted the highways near her home and killed anyone who got close. When Sam and Dean drive the car into the house where she briefly attacks them, Constance is confronted by the ghost of her children and dragged into the afterlife.

During the show, numerous methods are employed to put the various ghosts to rest, but the most commonly used is salting and burning their human remains. Generally when a spirit's remains are salted and burned, they go up in flames. However, sometimes this is not possible due to cremation and they are attached to an object that must be salted and burned as well. Sam and Dean regularly use iron objects and rock salt shotgun pellets to battle ghosts as iron and salt repel them for a while.

In season 7, hunter Bobby Singer became a ghost for a time after his death to look after the Winchesters and help stop the Leviathan threat. When he began turning into a vengeful spirit, the Winchesters were forced to put him to rest.

While it was initially unknown where ghosts go after they are destroyed, hunters generally believed it to be oblivion. However, it is revealed in season 8's "Taxi Driver" that Reapers take the spirit to where they belong once the ghost has been forced from this plane of existence.

In season 9's "Captives" and "Stairway to Heaven", the ghost of Prophet Kevin Tran and the Reaper Tessa reveal that the closing of Heaven has trapped all of the ghosts who since died in the Veil.

This is rectified when Metatron is defeated and Heaven is reopened as seen in season 10's "Angel Heart" where the recently deceased Amelia Novak is reunited with her husband in Heaven. Additionally, the Winchesters are twice shown to convince a ghost to move on rather than forcing them to though they revert to their old method of dealing with ghosts in "Paint it Black." In the first instance in season 9's "Bad Boys", the ghost is attached to her young son rather than an object and the boy convinces her to go on. In the second instance, season 10's "Halt & Catch Fire", the ghost is haunting the Internet and there is no way to destroy him through usual methods. Instead, the man's wife convinces him over FaceTime to move on.

At the end of season 14, God opens every door in Hell and unleashes billions of condemned souls upon the world, some being old enemies of the Winchesters like Constance Welch, Mary Worthington, and John Wayne Gacy.

In the first three episodes of season 15, the Winchesters and their allies attempt to contain Constance Welch, Mary Worthington, John Wayne Gacy, Lizzie Borden's ghost, Francis Tumblety's ghost, and other unnamed Hell Ghosts to Harlan, Kansas where they emerged and find a way to send all of them back to Hell. Using a spell from the demon Belphegor, the Winchesters contain the ghosts for a time, but the barrier begins to fail. Belphegor proposes a plan to use Lilith's Crook, a magical horn created by Lilith, to draw all of the Hell Ghosts back into Hell while Rowena performs a spell to close the rupture. Castiel is forced to kill Belphegor after he betrays them and Rowena sacrifices herself to cast them back into Hell.

Leviathans were first introduced as another primary "creation" of God in the Season 7 premiere. According to Death, the Leviathans were among God's earliest creations but were sealed in Purgatory because they were a threat to His other creations. Castiel accidentally absorbs them, along with the souls in Purgatory, during his attempted apotheosis, and the Leviathans free themselves. Once free, they organize a hierarchy with the Leviathan possessing the businessman Richard "Dick" Roman as the leader, though Crowley claims that this being has always been their leader.

The Leviathans are portrayed as virtually indestructible, voracious, and stronger than demons and low-level angels. They can shape-shift into humans, but to do so, they must use traces of their DNA. Leviathans not only replicate the corporeal form of a human, but also their memories and skills. They also have the ability to kill angels with brute force alone. Leviathans' weaknesses include magic, borax, and decapitation, though none of these are lethal. One way for a Leviathan to die is for it to be eaten by a Leviathan. Late in season seven, the characters find a tablet containing the "Word of God" that reveals a Leviathan can be killed by using "a bone of a righteous mortal washed in the blood of the three fallen". When this happens, the Leviathan liquefies and explodes.

In season seven, the Leviathans, led by Roman, plan to turn humankind into a farmed, Leviathan food source. They intend to do so through chemically decreasing their intelligence via food adulterants and curing their diseases, including cancer. The Winchesters put a stop to this during the season finale, with Dean and Castiel killing Roman, which, as a side consequence, sends them to Purgatory. Killing Roman, the only Leviathan leader that there has ever been, severely weakens the Leviathans, as they are now directionless. According to Crowley, they will now be regular monsters, albeit ones that are much harder to kill.

Shapeshifters are one of the most commonly appearing monsters in Supernatural. While shapeshifter is a somewhat general term, members of the species have also been shown using it when discussing their species with others. In particular, shapeshifter David Lassiter called himself a shapeshifter to Ennis Ross in season 9's "Bloodlines" and proceeded to describe what it meant. Having a human appearance, they are able to shapeshift into whomever they like, living or dead and perfectly mimic their appearance. As seen on a few occasions, unlike most monsters, shapeshifters are not created through a person being turned but are in fact made through sexual reproduction with one shapeshifter parent and one regular human parent. Most shapeshifters shed their skin when changing appearances, but in season 9 a few were able to change form without shedding skin similar to the Alpha Shapeshifter, the very first shapeshifter. They are vulnerable to silver which burns them on contact and kills them when they are stabbed or shot through the heart with it. On camera, their eyes give off a glow referred to as a retinal flare which helps to identify them.

Unlike many monsters, shapeshifters are not hunger-based and instead retain human impulses and desires which they use their powers to act upon. As a result, shapeshifters that are evil consciously choose to be rather than because of some innate impulse. On a few occasions, a shapeshifter has turned out to commit a murder or murders originally attributed to ghosts due to their ability to mimic the dead making it seem like the ghosts of the people they impersonate have come back for revenge. While some shapeshifters simply cycle through different forms and never seem to settle on one particular look, others have been shown to have a preferred appearance that they use as their base form for when they are not impersonating someone. It is never made clear if this chosen base form is simply a preference for the shapeshifter or is in fact what they originally looked like. Shapeshifters do not appear to be able to sense others of their kind as the Winchesters encountered a shapeshifter in season 13 that could not tell that her ex-boyfriend, another shapeshifter, was impersonating one of her patients. She also could not tell which it was once she knew that he was.

A shapeshifter first appears in season 1's "Skin", Sam and Dean's first encounter with one over their entire hunting career. Having taken the form of Sam's college friend Zach, the shapeshifter had framed him for murdering his girlfriend and was targeting couples by taking on the form of one member while they were away and harming their partner. In the form of Dean, the shapeshifter attacked a SWAT team sent to apprehend it, effectively framing him for its crimes. In the end, Dean killed the shapeshifter with silver bullets to the heart as it tried to kill Sam. The Winchesters then used its body, still in Dean's form, to fake his death and exonerating Zach and everyone else the shapeshifter framed at the same time. The shapeshifter's crimes play an important role in the Winchesters' relationship with the law, particularly as Dean becomes wanted for them once he is revealed to still be alive.

Vampires are Supernatural's most common monsters, appearing in every season except season 4. Supernatural's vampires differ greatly from common vampire lore, a fact that is pointed out in their first appearance by John Winchester. In Supernatural, vampires are not affected by crosses or garlic while sunlight hurts, but is not fatal to them. In addition, vampires cannot be killed through a stake to the heart. The primary method of killing a vampire is instead decapitation while dead man's blood—the blood of a dead person—acts as a poison and sedative to them, though it is not fatal in the long run. Their bloodlust is very real and like mythological vampires they are driven to feed on humans. They can reproduce by feeding a human their blood or directly introducing it to the person's bloodstream. According to Dean Winchester, the time it takes a person to turn depends on that particular person: sometimes it can be fast and sometimes it can be slower.

Unlike most monster species, vampires can occasionally be cured and reverted to their original human state. This cure requires the blood of the sire vampire and for the new vampire to have not drank even a single drop of blood or the cure is ineffective. As mentioned in season 13's "Breakdown", two other ingredients are garlic and sage. The cure is mentioned to make the recipient sick for a few days after it is taken. It was developed by the Campbell family of hunters at some point in the past and is referred to as "an old family recipe" by Samuel Campbell. After learning of the cure when its used on Dean, the Winchesters put it to use occasionally to save recently turned vampires who have not yet fed. While other hunters are generally unaware of the cure's existence or how to make it, the Winchesters have shared it with a few others while using it during hunts. However, use of the cure is rare as the requirements, specifically the need for the vampire not to have fed yet on even a single drop of blood, make it rare that a situation is encountered where using the cure is an option.

Vampires first appear in season 1's "Dead Man's Blood" where a group led by Kate (portrayed by Anne Openshaw) and Luther (portrayed by Warren Christie) attack and kill hunter Daniel Elkins and steal from him a legendary gun known as The Colt which is rumored to be able to kill anything. Elkins' murder draws the attention of the Winchesters and their father who was a friend of Elkins and had never told his sons about vampires as he had believed the species to be extinct. John leads his sons on a pursuit of Elkins' killers as he sees The Colt as their only way of killing Azazel. Sam and Dean rescue the vampires' human victims and disobey orders to come to their father's rescue during an ambush. John uses The Colt to kill the vampire leader Luther, proving the legendary gun's power while two vampires manage to escape.

In season 2's "Bloodlust", Sam and Dean encounter a nest of vegetarian vampires that feed only on animals and consist of Lenore (portrayed by Amber Benson), Eli (portrayed by Ty Olsson), Conrad, and Christina Flanagan (portrayed by Janeane Carltone). This nest is being hunted by ruthless hunter Gordon Walker who wants to exterminate the entire species due to his sister getting turned. Though Dean originally sides with Gordon, he changes his mind upon seeing Lenore resist her cravings for human blood. Instead, the Winchesters help the vampires to escape and make an enemy of Gordon in the process. Lenore later returns in season 6's "Mommy Dearest" where she reveals that the influence of the Mother of All Monsters Eve caused her nest to return to feeding on humans. After giving the hunters Eve's location, Lenore is killed by Castiel at her own request.

In season 3's "Fresh Blood", the Winchesters come up against a vampire named Dixon (portrayed by Matthew Humphreys) who is trying to create a new nest following the extermination of his old one by hunters and the loss of his daughter. At the same time, vampire hunter Gordon Walker attacks in hopes of killing Sam and is caught by Dixon who changes Gordon into a vampire. By the time the Winchesters track Dixon down, Gordon has killed his "new daughters" and escaped and a depressed Dixon asks to be killed. Using his new powers, Gordon tries to kill Sam, changing a young woman into a vampire as part of a trap. Dean kills the young woman with The Colt while Sam manages to decapitate Gordon with razor wire.

Werewolves are one of the most recurring types of monsters on Supernatural. In the earlier seasons, werewolves are generally just mentioned in regards to old hunts or wrongly suspected as a culprit, making only a single appearance in season 2. It is not until their second appearance in season 8 that werewolves emerge as a more common type of monster. Werewolves are people who can change their appearance to gain claws, fangs, fur and superhuman abilities. Unlike most common lore and portrayals, werewolves do not change completely into a wolf-like appearance or a bipedal wolf-like appearance in this show. In Supernatural, werewolves can be created both through being bitten and through sexual reproduction. Supernatural features two types:

• Regular werewolves are the type that the Winchesters hunted in their earlier years while purebloods are the type featured in the later seasons of the show. Regular werewolves have no control of themselves and run on pure instinct. They appear to change while sleeping and the person lacks any memory of their actions. Regular werewolves are bound to the full moon for their change.
• Pureblood werewolves, which are from generations closer to the Alpha Werewolf, the first werewolf, can control the change which can happen at any time. Unlike regular werewolves, purebloods remember what has happened when they have transformed and if they choose, can control themselves rather than running on instinct alone. They can control their cravings and survive by feasting on animal hearts rather than human hearts if they so choose.

Werewolves of both types can be killed by silver to the heart and it is generally believed that there is no cure for lycanthropy. John Winchester believed that killing the sire werewolf would cure anyone they turned, but this turned out to be false. Other hunters, including Bobby Singer, were aware of this and believed there to be no cure.

In season 12, a group known as the British Men of Letters developed an experimental cure using the live blood of the sire werewolf which member Mick Davies called plasma therapy. It has to be administered during the early stages of lycanthropy and the werewolf cannot have killed anyone. Also, the sire werewolf has to be alive when the blood is drawn, complicating matters even further. Prior to the episode, the cure had only ever worked on rodents and even then only a single test subject out of ten. Their one-human test subject died in agony, causing the organization to abandon work on the cure. During the episode "Ladies Drink Free", Claire Novak becomes the first ever cured werewolf and while the cure works, it is excruciatingly painful for her and appears to work over a protracted period of time.

In season 2's "Heart", the Winchesters hunt a werewolf in San Francisco and discover that Sam's new love interest Madison (portrayed by Emmanuelle Vaugier) is a werewolf. The Winchesters determine that Madison was bitten by another werewolf who has been targeting prostitutes a month before and set out to try to save her. Following a theory in their father's journal, Dean kills the sire werewolf, Madison's neighbor Glen, in hopes of severing the bloodline to cure her. However, while sleeping with Sam that night, Madison transforms and escapes. With all other hunters stating that there is no cure, including Bobby Singer, Madison has a reluctant Sam kill her to keep Madison from hurting anyone else.

Season 8's "Bitten" is portrayed as a found footage episode following three young college students after one of them, Michael, is bitten by a werewolf and transforms. Michael becomes a pureblood werewolf which the three learn by following the Winchesters around. As Michael fights his instincts which leads to him killing people, his girlfriend Kate tries to protect him while his best friend Brian seeks to become a werewolf himself to become stronger, something that Michael resists doing. Brian eventually identifies their professor as the werewolf who bit Michael and the professor confesses that after years of surviving on animals, he gave into his instincts and killed someone. Knowing hunters would come, he turned Michael as a scapegoat. Brian forces the professor to turn him and the professor is subsequently tracked down and killed by Sam and Dean. Before dying, he thanks them for freeing him from what he felt was a curse. Driven insane by the power he has gotten, Brian kills Michael and turns Kate to be with her. Instead, Kate kills Brian and compiles all of the footage he has been putting together into a movie to show the Winchesters that they were not always monsters and did not want to become what they did. The Winchesters decide to give Kate a chance and do not hunt her down.

In season 9's "Sharp Teeth", the Winchesters discover that their friend and fellow hunter Garth was bitten on a hunt and became a pureblood werewolf. Garth joined a pack of supposedly-friendly werewolves after marrying the daughter of their leader. While most of the werewolves, who prefer to be called lycanthropes, are harmless, a small part of the pack turns out be part of a cult worshipping the Norse godFenrir who they believe will bring about werewolf domination of the Earth when Ragnarok comes. The cult, led by Garth's mother-in-law, kidnaps Sam, Garth and Garth's wife Bess to murder Garth and Bess and frame the murders on Sam to spur the rest of the pack to join them. After figuring out the truth with the help of the pack's leader, Dean rescues the three and single-handedly kills all of the cultists. The Winchesters leave the rest of the pack be due to their peaceful nature. Later, in "Bloodlines", the Duval Family of Chicago are one of the Five Monster Families in the city. According to shapeshifter David Lassiter, the werewolves control the Gold Coast. The murder of shapeshifter Sal Lassiter by what appears to be a werewolf nearly drives the families to war. However, the Winchesters, wannabe-hunter Ennis Ross, shapeshifter David Lassiter and his ex-girlfriend werewolf Violet Duval discover that the true culprit is an insane hunter and prevent the war.

In season 10's "Paper Moon", the werewolf Kate returns as a suspect following several murders committed by a werewolf. Having worked hard to control herself, Kate reveals that she turned her sister Tasha to save Tasha's life after a serious car accident. Tasha refused to follow Kate's way of thinking and instead began building her own pack that hunts people. The Winchesters easily kill Tasha's two pack mates while Kate, after seeing the monster that Tasha has become, kills her sister herself before leaving again.

In season 11's "Red Meat", the Winchesters take on a werewolf case in a national park to take a break from their conflict with the Darkness. Unknown to them, the helpful bartender is the pack leader and she directs them right into a trap. The Winchesters manage to kill two werewolves, but Sam is seriously wounded when one werewolf shoots him with his own gun. The Winchesters rescue a young couple, Corbin and Michelle and are unaware the Corbin has been bitten. Chased by the remaining werewolves and dealing with the seriously injured Sam and Michelle, Corbin suffocates Sam when Dean will not leave him behind, apparently killing Sam. Though devastated, Dean helps Corbin and Michelle escape to a hospital where Corbin subsequently transforms into a werewolf and kills a doctor. At the same time, Sam, who was only put into a near-death state, regains consciousness in time to kill the remaining two werewolves and use their truck to return to the Impala. Sam arrives at the hospital in time to save Dean from Corbin who has become intoxicated by his new power as a werewolf, forcing Sam to kill him.

In a flashback to 1980 in season 12's "Celebrating the Life of Asa Fox", Mary Winchester kills a werewolf she has history with in Canada, saving the life of a young Asa Fox. The incident inspires Asa to go on to become a legendary hunter. In "Ladies Drink Free", the British Men of Letters have been systematically attacking werewolves along with other American monsters, using sulphate gas and silver nitrate to wipe out entire packs. As a result, a pureblood werewolf named Justin, driven insane by loneliness after his peaceful pack was killed, turns a girl named Hayden Foster to be his mate, murdering her brother at the same time. The action draws the attention of British Men of Letters operative Mick Davies who calls in the Winchesters for help. After discovering that Hayden is a werewolf, Mick reluctantly kills her with a silver injection. In response, Justin turns young hunter Claire Novak to replace Hayden. Due to her emotional issues, Claire requests to be killed as she doesn't believe she can control herself, but the Winchesters instead decide to try an experimental cure created by the British Men of Letters to save her, a cure that has never worked on a human subject. As the Winchesters try to find Claire's sire, Justin attacks and abducts Claire, but the Winchesters and Mick follow him using a tracker implanted on Claire by Mick. During the scuffle that follows, Mick manages to draw Justin's live blood before killing him with a silver bullet, allowing the Winchesters to create the cure. Though Claire experiences excruciating agony, she becomes the first werewolf ever to be cured.

In season 13's "Wayward Sisters", Claire hunts a small werewolf pack who kidnapped a young girl. Disguised as a delivery person, Claire kills the pack and rescues the girl before being called by Jody Mills to help as the Winchesters have disappeared. Subsequently, in "Breakdown", a werewolf is shown to be part of Terrance Clegg's online auction and wins the bid for Sam Winchester's heart. However, he never gets it as Clegg is killed by Dean moments later. In "Let the Good Times Roll", a pack of three werewolves is hunted by the Winchesters, Castiel and the Nephilim Jack. Castiel ambushes one outside of their hideout as he tries to smoke a cigarette and kills the werewolf with his angel blade. As the other two argue about the Kardashians, the Winchesters and Jack enter. Jack immobilizes the werewolves using telekinesis and Sam and Dean kill them with silver bullets without a fight.

In season 14's "Gods and Monsters", Michael approaches a werewolf pack to get their help in forming an army of monsters to destroy humanity. The pack leader agrees to work with Michael who enhances the werewolves using angel grace. Subsequently, four enhanced werewolves attack Sam and Mary Winchester along with Bobby Singer in an old church. Owing to their enhancements, they are stronger and faster than ever and immune to silver. However, Sam discovers that they are still vulnerable to decapitation which allows him and the other hunters to kill the four enhanced werewolves.

Witches are magic users appearing throughout Supernatural. According to witch Rowena MacLeod, the Grand Coven classifies witches into three categories: The Naturals, the Borrowers and the Students. The Naturals are witches born with natural power and are rare, Borrowers are witches who gain their powers through demon deals while the Students are witches who learn either on their own or are taught by other witches, but lack innate power and do not get it from a demon. Owing to the nature of the source of their powers, Borrowers are condemned to Hell as they have sold their souls for power. On Supernatural, witches mainly act through hex bags, a small cloth bag full of ingredients that acts as a medium for their spells. As a result, destroying the hex bag is usually enough to break a spell. Witches also often carry spell books known as grimoires. Examples are the Book of the Damned and the Black Grimoire which play major roles in the later seasons of the show.

As they are human, witches can die with the weaker witches being able to be killed through simple mortal injuries though stronger witches tend to be invulnerable to normal methods of harm. In season 11's "Love Hurts", Dean notes that being stabbed with a knife would only slow down a powerful witch rather than kill her. On several other occasions, powerful witches have scoffed at the idea of bullets harming them. In the earlier seasons, witches are more often than not killed by demons they have been dealing with than the Winchesters themselves. In season 8's "Man's Best Friend With Benefits", the Winchesters succeed in using a witch-killing spell learned from Bobby Singer in season 7's "Shut Up, Doctor Phil", to kill a hostile witch, albeit with the help of a distraction from a friendly witch's familiar. However, in season 10's "About a Boy", the same spell fails when the potion part of it is destroyed by the witch. Instead, Dean kills her by burning her in her own oven. In "Brother's Keeper", Sam modifies the witch-killing spell to be contained in hollow-point bullets. These new bullets, dubbed witch-killing bullets, are extremely effective against witches, killing even the most powerful witches who scoffed at the idea of bullets harming them. Seeing their first successful use in season 11's "Love Hurts", the bullets are used by the Winchesters whenever they come up against a witch, generally ending with the witch or witches being killed through being shot with the bullets.
