Castiel is an all-powerful angel warrior of God and is responsible for pulling Dean Winchester out of Hell on God's command. He was assigned as Dean's protector so he could prevent Lilith from breaking the 66 Seals that would release Lucifer. When Castiel learned that the angels wished to free Lucifer, he defied his angelic siblings and died trying to help Dean prevent Sam from breaking the last seal that would release Lucifer.

After he was killed by Raphael, Castiel was resurrected by God and he appointed himself as the Winchester brothers' protector to prevent them from becoming the vessels of Michael and Lucifer. When the Apocalypse was averted, he started a civil war in Heaven to prevent Raphael from restarting the Apocalypse once again. With no other choice, Castiel teamed up with Crowley to claim the souls of Purgatory. He ended up betraying Crowley and absorbed all the souls of Purgatory, resulting in his powers reaching that of the level of a god but at a high price: the power that the evil souls have granted him has warped Castiel's mind, causing him to proclaim himself as the new God.

A possible main antagonist in Season 7.

NOTE: In folklore, Castiel is the Angel of Thursday, possibly chosen to be a character in Supernatural because it (then) aired on Thursday nights. This is also pointed out by Crowley in the episode The Man Who Would Be King .


The appearance of Jimmy Novak, Castiel's vessel, is that of an average human male, in his thirties, who is returning from a hard day's work in the office environment of an accountant. He sports a pair of dress shoes, dress slacks, unbuttoned white-stripped dress shirt, and loosened necktie accentuated by a beige trench coat. Although he has a very dire demeanor, his outward appearance radiates a natural calm and serenity, which makes conversation easy and direct.

As an angel, seeing his actual form will result in blindness, as the appearance of his natural "visage" is so overwhelming that it is capable of burning human or demon eyes from their sockets. However, Castiel stated certain "special people" are able to tolerate his true appearance and voice. Although his true form has never been seen, it is known that it is approximately the size of the Chrysler Building and, like all angels, has feathered wings.


Like most angels, Castiel expresses little to no emotion. Despite this, he does not display the blank apathy or mocking superiority complex that seem to characterize angels such as Uriel or Lucifer. His lack of emotion and understanding of human traits such as sarcasm have often led to humorous situations throughout the show and have occasionally almost got him into trouble with humans only for Dean or Sam to fix things.

Unlike many of his brethren, Castiel still has faith in his father, though not to the near zealot-like level displayed by Michael. While he admits he may not always understand what God wants and question the reason for it, he would always follow his father to the best of his abilities. This, along with his interest in humans, has caused other angels to label him as odd or naive. Anna and Lucifer have both demonstrated this, with Anna calling him a hypocrite for refusing to rebel in order to gain more freedom. Castiel frequently exhibits what could be referred to as friendly affection towards Dean, and seems to at the very least come close to expressing regret, hesitance, and anger several times.

Being around the Winchesters and his own experiences in the War have taught Castiel several "tricks" that have helped him during the show. While not possessing free will in the same sense as a human, Castiel has learned how to "bend" the rules at times in season 4. The best example is when he informs Dean about Chuck's archangel thereby giving Dean the idea to use him to save Sam from Lilith ("The Monster at The End of This Book", season 4 episode 18). He also is able to distract Meg long enough to use her and a similar trick Uriel performed to free Alistair to free himself from a ring of holy fire ("Abandon All Hope", season 5 episode 10). Castiel also considers himself to be the Winchester's guardian.

When Castiel is brought back from the dead after Lucifer kills him, he begins to develop a sense of pride. During Season 6, Castiel's personality begins to change. It's this pride that made him fail to realize that when he brought Sam back, he brought him back soulless. It is also because of this pride that Castiel makes a deal with Crowley, and starts the civil war in heaven.

Upon absorbing the souls, Castiel claimed himself to be God, a fact that was proven by his personality and attitude changing.

Previously acting kind and assuring but also fierce at times, Castiel has now become purely cold and evil as seen when he kills Raphael without any second thoughts before demanding that Dean, Bobby, and Sam kneel before him and tell him they love him or he will destroy them.

Early Life

Discussions with Uriel suggest the pair were children by angel standards when Lucifer rebelled against Heaven and refused to bow down to humanity. While his brother was instantly enthralled by Lucifer's power and charisma, Castiel remembered being frightened and disturbed by the rebellious archangel. Castiel had been stationed on Earth for at least 2,000 years while being in the same garrison as Anna Milton, acting as his superior, and Uriel. Castiel was there when the world was first created. He watched as the first fish emerged from the ocean. He also watched them build the tower of Babel, among other historic events.

Jimmy possessed

Castiel possesses Jimmy Novak

In 2008, Castiel speaks with his true vessel, Jimmy Novak, in Pontiac, Illinois. When Jimmy is watching television, Castiel's voice distorts the picture and causes him to scream in pain and his body to spasm until he finally blacks out. Later, Castiel would tell Jimmy to put his in arm in boiling water and that he would be unharmed as a way to prove his faith. With his wife believing that he's going crazy, Jimmy asks Castiel what he wants from him and how he can help. Castiel explains that he needs to use Jimmy as a vessel, to which Jimmy agrees to as long as his family is protected. After receiving consent, Castiel possesses Jimmy. Before he leaves, Castiel is confronted by Jimmy's daughter, Claire, and tells her that he is not her father.

Season Four

Castiel shows his wings

Castiel shows his true nature to Dean.

When Dean Winchester broke the first of the 66 Seals that would allow Lucifer to walk free, the angels took action. They fought their way to Hell and Castiel freed Dean from the pit. Dean awoke in a grave and made his way to the surface, not knowing how he had been resurrected; the only clue he had was a large imprint of a hand near his shoulder.

After reuniting with Bobby Singer and Sam Winchester, Dean tried to learn what had rescued him from Hell. He also discovered that he'd been dead and buried for four months. Eventually, Dean took matters into his own hands and with Bobby's help, set a trap for the creature and protected himself and Bobby with multiple Devil's Traps and other anti-demon devices.

Castiel arrived and the hunters shot at him as he passed through the Devil's Traps with ease. Castiel quickly knocked out Bobby with a mere touch and Dean stabbed him with Ruby's knife but it had no effect. Castiel explained who he was to Dean and that God has work for him.

Castiels informs Dean about Lucifer and the 66 seals

Castiel informs Dean about the 66 Seals.

After people who were supposed to be dead seemed to be rising from the grave, Castiel appeared to Dean and explained to him that this was one of the 66 Seals, "The Rising of the Witnesses." Castiel told him that Lilith was attempting to break 66 of the seals which would lead to Lucifer walking free on Earth and then the Apocalypse would begin. The angels had been fighting to stop the demons, but the odds were against them. He explained to Dean that he must help stop the breaking of the seals as well. Castiel also showed that he was not a force to be underestimated or even taken lightly as in a chilling tone, he told Dean to start showing him some respect or he'd change his mind and throw him back into Hell again.

Castiel and Dean in the past

Castiel and Dean in the past.

One day, when Dean was asleep, he woke up to find Castiel sitting beside him. Castiel, without speaking, tapped Dean and brought him back in time to an important few-day period. It showed Dean the connection between Azazel and Mary Winchester, and answered questions that had always been on his mind. Castiel said that the reason he had brought Dean back to that period was to make sure that he was caught up with all of the facts. He also explained that the angels are still unaware of Azazel's endgame. Castiel also told Dean about Sam's developing abilities and that he was going too far down a dark path and that if Sam did not stop using his powers, then the angels would kill him.

Sometime later, Castiel and his partner Uriel met with the Winchesters when they were in the middle of hunting a witch. The angels explained that the witch was trying to summon the demon Samhain from Hell and that this was another one of the 66 Seals. The angels said that they would have to destroy the entire town and all of its residents to ensure that the seal would not be broken. The brothers argued against this and assured Castiel and Uriel that they could stop the witch from summoning Samhain. Unfortunately, they failed and Samhain rose, breaking another seal.

Castiel and uriel

Castiel and Uriel came for Anna Milton.

When the angels learned that a woman named Anna Milton could listen in on angel's conversations, they grew worried. If the demons were able to get to her before them, the demons would know everything that the angels were planning. But Castiel knew the truth: Anna had once been an angel, a superior to him, who disobeyed. She cut out her Grace and fell to Earth, where she was reborn as a human. Castiel and Uriel knew though that the only way to ensure the safety of their plans were to kill Anna. While Castiel was hesitant about this, Uriel enforced the idea that it was absolutely necessary. Castiel and Uriel found Anna along with the Winchesters. The angels ordered Sam and Dean to hand over Anna, but they refused. The angels attacked them and almost retrieved Anna, but were sent away by a ritual Anna performed. They later were able to find Anna with the Winchesters again, but soon discovered that they had been led into a trap when Alastair arrived with a group of demons. The angels and demons fought over who would take Anna and the battle ended when Anna retrieved her Grace and vanished.

Castiel beaten up by Uriel

Castiel betrayed by Uriel.

When Alastair tried to break another seal by killing two Reapers on the night of the Solstice, Castiel managed to capture him. The angels held Alastair captive and when seven angels had mysteriously been killed, Castiel assumed that demons were behind the attacks. He and Uriel recruited Dean to interrogate the demon. During the interrogation, Anna returned and spoke with Castiel. She told him that she knew how he was feeling and that he was beginning to develop human emotions. Castiel refused to believe this and yelled at her, causing her to leave. Shortly after, the Devil's Trap Castiel had made to hold Alastair somehow malfunctioned and Alastair nearly killed Dean. Castiel fought the demon but was almost defeated when Sam came to his rescue, using his psychic powers to kill Alastair. While visiting Dean at the hospital, Sam criticized Castiel for being so cold-hearted as to risking Dean's life. This sunk into Castiel's head and he went to Anna for help, telling her he needed to know what to do; she told him it was time for him to decide on his own for once. Castiel investigated the broken Devil's Trap further and learned that it was Uriel who was behind the malfunctioning Devil's Trap and the angel killings. Uriel reminded Castiel of the times when Lucifer was one of the greatest angels and also spoke about how God isn't doing anything and they must follow someone who would. Castiel refused and the two angels fought. They were evenly matched until Anna arrived and killed Uriel. Castiel then went to Dean and confirmed that Dean was responsible for breaking the first seal by giving in to Alastair's torture. Dean begged Castiel to find someone else because he wasn't fit to stop the Apocalypse.

Castiel later appeared when Dean interrogated Chuck Shurley, who was writing a book series based on the Winchester brothers, explaining that Chuck was a Prophet of the Lord. When Dean asked him for help in saving Sam from Lilith, Castiel was initially hesitant to help, but dropped him a hint by telling him that Prophets are protected by archangels, and that if a Prophet is in the same room with a demon, then the archangel will descend to smite the demon.

Castiel in Jimmy's daughter

Castiel inside Claire's body, keeping his promise.

Castiel then came to Dean while he was dreaming and told him to meet him at a certain location, saying that he has something to tell them. But when Dean and Sam arrived, they found him unconscious in a wrecked building with dead demons. When he awoke, the brothers found that Castiel had abandoned his vessel, Jimmy Novak, who describes being possessed by Castiel was like "being chained to a comet." When Dean, Sam, Jimmy and Jimmy's daughter Claire are being held hostage by demons, Jimmy was shot and Castiel returned to possess Claire and helped save them all. While Castiel tried to comfort a dying Jimmy, Jimmy pleaded with Castiel to take him back as a host and Castiel accepted. When Dean asked Castiel what happened, he coldly replied, "I learned my lesson while I was away, Dean. I serve Heaven; I don't serve Man. And I certainly don't serve you."

Later in "When the Levee Breaks" Castiel was summoned by Dean, who was screaming three hours long for help. When Castiel arrived, Dean asked him what happened in Heaven, but Castiel wouldn't say. Then Castiel recruited Dean in the service of God and his Angels. Castiel told him to wait till the Angels summons him. A few hours later he freed Sam from Bobby's panic room he was holding in, because of his addiction. Later Anna confronted Castiel about why he released Sam. Anna said that Sam was even worse than they had expected. Castiel told he has his orders to follow and then said to Anna that she shouldn't have come. The next moment two Angels stood beside her, and took her captured.

Castiel starts his rebellion

Castiel starts his rebellion against Heaven by helping Dean.

Later Zachariah brought Dean to a chamber, so he would be safe for the release of Lucifer. Zachariah told that the final seal would be broken that night. Although had a fight with Sam, he tried to contact him on his cellphone, and left a message on his voice-mail. Later Dean wanted to talk with Sam and summoned Castiel, by breaking an Stone Angel, on one of the table. Dean asked to visited Sam, but Castiel that he could go everywhere, but not to Sam. Dean asked what they are gonna do with Sam. Castiel said that Sam is gonna do it to himself, but more he didn't want to say. He said it was his destiny. Dean said that destiny was just a bunch of lies, to keep him line. Dean tried to purchase Castiel to help him, but Castiel said that we would be all be hunted, that we would be all dead. In responds Dean said to him that this is worth dying for. But Castiel refused, to Dean's disappointment. A few moments later, Castiel confronted Dean and drew an Enochian Sigil on the wall with his own blood. Then Zachariah appeared and asked what he was doing. Then Castiel hold his bloody hand on the sigil, that drew Zachariah away. He then said that Lillith is the final seal and that Sam is going to break it. He said that he know someone that knows where Sam is and teleported Dean with him.

Castiel and Chuck faces the Archangel

Castiel and Chuck face Raphael, the Archangel

Castiel teleported Dean and himself to Chuck, the prophet of the Lord. Chuck was confused and said that this is not supposed to be. That they were not in the story. Castiel said that they would make it up. When they found out that Sam was at Saint Mary's, Chuck’s computer goes off and bright light fills the room. Castiel said it is the Archangel and teleported Dean to Saint Mary's, so that he could hold the Angel off. At Chuck’s, Castiel looks up at the bright light. Chuck puts his hand on Cas’s shoulder, and when Castiel gives him a look, he removes it.

Season Five

Castiel confronts Zachariah

Castiel confronts Zachariah and orders him to heal Sam and Dean.

After witnessing the release of Lucifer from Hell, Dean and Sam go to Chuck's house to find Castiel. There they are told by Chuck that the archangel smote Castiel; they even find one of his teeth tangled in Chuck's hair. Later, when the Winchesters are trying to track down Michael's sword in their father's old storage unit, Zachariah and his angels arrive to inform Dean that he is Micheal's sword—in other words, Micheal's vessel. When Dean refused to give his consent for Michael to possess his body, Zachariah started inflicting various kinds of physical pain on him and Sam (breaking Sam's legs and removing his lungs, and giving Dean stage-four stomach cancer), all the while refusing to kill them. Castiel then miraculously appeared and dispatched Zachariah's men, then forced Zachariah to heal the Winchesters and leave. He then used his powers to carve Enochian Sigils on their ribs, keeping them hidden from all demons and angels, including Lucifer.

After rebelling against the angels Castiel's powers began to deteriorate whilst he searched for god using Dean's amulet however despite his vanishing strength he continued to be invaluable to the brothers saving them on numerous occasions.

In "Dark Side of the Moon," when the brothers are ambushed and killed by several hunters furious with them for causing the Apocalypse, Castiel warns the brothers that Zachariah is looking for them in Heaven and they should attempt to contact an angel named Joshua, who is rumored to speak to God. When the brothers return from death, Sam reveals that God wants nothing to do with them, causing Castiel to abandon his belief in God and return Dean's amulet, stating that it's worthless.

Castiel brought back as an Archangel

Castiel after he was brought back from death.

In the episode "Two Minutes to Midnight" (By which point Castiel had been stripped of all his Powers, in other words he was human until after Swan Song) he assisted Sam and Dean against the 3rd Horseman Pestilence by cutting off his finger obtaining one of the 4 rings needed to seal Lucifer back into the pit. In the Season Finale when Michael (Possessing the Vessel of Adam Milligan) was about to fight Lucifer (Possessing the Vessel of Sam) Dean intervened saying he wished to speak with Sam which prompted Michael to remove Dean however before he could respond Castiel threw a Molotov of Holy Fire at Michael sending him back to heaven for a brief time. Lucifer turned to Castiel, furious by the fact that Castiel harmed his brother, and caused Castiel to explode (Literally). Shortly after the battle between Sam and Lucifer, Castiel was resurrected by God with his angelic powers restored and upgraded, allowing him to restore Bobby Singer to life. Castiel, presumably now an Archangel, said that he needed to return to Heaven to restore order to the anarchy that will follow Micheal's departure.

Season Six

After the Apolocalypse was averted, Castiel returned to Heaven where other angels awaited him. He tried to tell them about freedom, but none of them understood. Castiel finds out that Raphael wanted to take over and follow Michael's departure and restart the Apocalypse again. Unable to stop him, Castiel wants to turn to Dean, but can't. Then Crowley shows up with a deal to find Purgatory and offers Castiel power to stop Raphael. So Castiel starts the civil war in heaven.

When Sam and Dean found out the plagues that were unleashed upon the Earth, they call Castiel for help. Castiel showed up and told them the Angelic Weapons was stolen from heaven. He also mentioned that he didn't know what or whom brought Sam back from Hell.

SPN 1185

Raphael overpowers Castiel.

In their investigation, they find out that an Angel has been moonlighting as a crossroads demon. To locate the Angel's name, Castiel performed a ritual to find the angel that bought the soul. When Castiel found it was his old friend Balthazar, an Angel follower of Raphael showed up and attacked Castiel. Castiel managed to defend himself and let the Angel go away, but the Angel knew that Balthazar was selling the pieces of the staff. So Castiel, Dean and Sam are trying to find Balthazar first, and when they did, Balthazar admitted that he stole the weapons from Heaven and that he want to live in freedom. When Balthazar disappears, Castiel is confronted by Angels that were trying to kill him. Castiel offered them to join his side, but they refused and Castiel killed them. Then Raphael showed up and told him that they were his followers, and he smashed Castiel away. Just when Raphael wanted to kill him, Balthazar showed up and used the weapons from Heaven to destroy Raphael's vessel. Eventually Sam and Dean showed up and were able to set Balthazar in a circle of holy oil, but Castiel lets Balthazar go.

SPN 0441

Castiel responds to Dean's call.

Dean becomes more and more disturbed by Sam's behavior, and prays for Castiel's help. He doesn't respond until Dean calls him about a 'possibly loose nuke', much to Dean's aggravation. Castiel apologizes, but reassures Dean on his theory that Sam is not Lucifer, explaining that all angels would feel his presence if Lucifer was free. Castiel also states he doesn't know what's wrong with Sam, but he promises to make inquiries.

Dean then calls on Castiel once he has Sam unconscious, and asks for him to diagnose Sam. Castiel then informs both brothers that physically, Sam is perfectly healthy, but his soul is missing. He guesses that Sam's soul is still in the cage with Michael and Lucifer. When Sam goes with Samuel as his only lead, Castiel follows Sam and Dean to the Campbell Compound to check if Samuel has a soul or not, which he does. However, before he can do any more to help, he states he needs to return to Heaven, but reassures Sam and Dean that their problems "always come first", and will keep in touch.

Castiel is later called on for assistance from Sam, who tricks him into leaving Heaven by saying he and Dean have found the Ark of the Covenant. Sam coerces Castiel into joining them along with the demon Meg and her minions to confront Crowley. Castiel tries to track down Crowley by means of a ritual, which leads them nowhere. When the group is caught by Samuel when they search through his quarters, Dean asks for the angel to leave back to their motel.

Castiel watches the Pizza Man
Sometime later, while Sam and Dean are looking through records trying to find Crowley, Castiel is confounded by watching porn, which he states just happened to be on the TV. He creates an awkward moment, even weirding Samuel out upon arriving at their motel. He leaves with the group after Samuel gives them the location of Crowley's prison. Before leaving for the prison, Castiel suggests to Dean that he doesn't think restoring Sam's soul is wise. He supports his statement with the fact that his soul has been locked in the cage with Michael and Lucifer for more than a year, and they have been doing nothing other than taking their frustrations out on Sam. He theorizes that if they try to force the damaged, tortured soul back into Sam, and if they fail to deal with the problems, then Sam will suffer horrifically.

The group then leaves for the prison, and Castiel finds a back entrance inside. Shortly after, hell-hounds come after the party. Meg distracts Castiel by kissing him, while stealing his angelic blade. Castiel, surprisingly, responds to this by kissing her back, stating he learned that from the porn he was watching earlier. The boys then run off while Meg holds off the hell-hounds with the angel blade. Later, Castiel is banished by a blood sigil cast by Samuel, while the Winchesters are taken captive.

While Crowley has the boys are pinned to the wall, Castiel reappears, carrying a large bag. After Crowley taunts him about his losing war against Raphael, Castiel reveals that the bag contains his salvaged bones. The angel asks the King of Hell one last time if he can restore Sam's soul or not. Crowley says he cannot, and Castiel proceeds to burn his bones, turning him to ash.

A short moment later, outside the prison, Castiel later admits that he is on the losing side of the civil war in Heaven, and expresses disappointment as he wishes much of the time that circumstances were different. Dean then reassures the angel that they will help in whatever way they can, and that the brothers are his friends. Castiel then turns to Sam, and reassures him that they will find another way to get his soul back. Sam then asks him to dispose of the monsters that still remain inside the prison, to which Castiel presumably leaves to do so.

After Sam gets his soul back, Castiel comes to check up on him, and tells Dean that he doesn't think Sam is ever going to wake up. Few hours later Sam wakes up and reunites with his brother. Later on Sam, now with his soul, calls Cas. Castiel comes and tells Sam he is glad to see him well, despite everything. Sam catches on and tricks Castiel into telling him the truth.

In My Heart Will Go On, Castiel saves Sam and Dean from Fate, when she tries to get her revenge for stopping the apocalypse. He tells the brothers if they want to live, they need to kill fate. So Sam and Dean draw fate out and just as they face their death, time freezes. Castiel confronts Fate and she reveals the real reason why Balthazar saved the Titanic. It was because Castiel order Balthazar to do it for the souls. She threatens to kill Sam and Dean unless Castiel fixes history. Castiel orders the creeping Balthazar to stop and right history.

Castiel wounded

Castiel wounded

In Frontierland, Cas returns to send Sam and Dean back to the Wild West so the brothers could aquire ashes of the phoenix, the one thing that could kill the mother of all. He tells Sam and Dean they have only 24 hours, after that he will no longer be able to find them. During the time the boys are in the Wild West, Castiel's lieutenant, Rachel, confronts him about his side dealings Castiel is doing to win the war. This leads to a duel between the two, and Castiel emerges the winner and wounded. He soon heads to Bobby's, draws a symbol in his blood and passes out. As time grows short, Castiel re-awakens, but is very weak and low on power. In order to "power up" he tells Bobby he needs to touch Bobby's soul. Once powered up, Castiel brings the boys back.

Now with the ashes, the hunt for Eve is on. He comes to Sam and Dean asking for Eve's location, but they too are unsuccessful. Sam suggests that they find a monster who would be willing to give them Eve's location. Castiel finds and brings Lenore, who gives them Eve's location, in exchange for her death. Sam is hesitant, but Castiel brings Lenore her end. This action makes Sam and Dean concerned about Castiel and his circumstances. Once they arrive in Organ, Castiel discovers he can't use his powers, and is now powerless, thanks to Eve. Castiel is later revealed to be working with Crowley after the Winchesters' encounter with Eve.


Castiel working with Crowley

The truth finally comes out in The Man Who Would Be King. Castiel recounts history from his point of view and how the Winchesters inspired him. Castiel also begins to notice that Sam, Dean and Bobby are getting suspicious of Castiel and believe he is working with Crowley. Castiel recounts about his return to heaven and his favorite place (the heaven of a 40 year old man who drowned in bath tub). This is after him bringing back Sam from hell, with exception of Sam's soul.

At the time, Castiel did not know Sam didn't have his soul. He also tries to get other angels to embrace freedom, but angels don't know how. Then Raphael tries to make Castiel bow to him, and Castiel refuses. Due to his misfortune, Castiel is no match for him. Castiel tries to get help from Dean, but seeing Dean retired makes Castiel rethink this. Then Crowley approaches Castiel with a deal, so Cas can become more powerful. Castiel begins his deal with Crowley. With this deal, Castiel starts the civil war in heaven. So when Crowley begins to threaten the Winchester's lives, Castiel becomes protective of them. Although Castiel managed to keep the secret for a while, until he slipped off with information he got from spying on them. Later the boys trapped him in a ring of holy fire and confront him about his betrayal. When demons come, Castiel tells the boys to run and they leave him in the ring of holy fire. Crowley comes in and saves him. Castiel leaves, and comes to Dean, trying to explain the situation. Castiel tells Dean that he did this for Dean and Dean does not it this way. Castiel responds that Dean can't stop him and says he's sorry and disappears.


Balthazar confronts Castiel

In Let It Bleed Castiel has taken one of the Campbell diaries, and is investigating an incident in which H.P. Lovecraft opened a portal to another world. Sam prays for him, telling Cas that Lisa and Ben have been kidnapped by Crowley, and asks for help. Castiel listens unseen, and does not answer, but goes to confront Crowley. He insists that the demon not harm Lisa and Ben, but Crowley refuses to make such a promise. Balthazar later calls him. He asks Cas if he is planning on opening the door to Purgatory; Cas lies that he is not, but Balthazar is not fooled. Castiel asks if he is with him, or not. Balthazar says he is.Castiel goes to Dean, arriving just in time to save him from a demon. He apologizes for Lisa and Ben, revealing that he did not know Crowley's plan. Dean is skeptical, and angry. Castiel asks him again to support his decision to tap the souls in Purgatory. He pleads with him that he has always done what the brothers needed him to, asking little in return. Cas asks them to trust in him, and promises to bring him his family afterward. Dean is unwilling, and Castiel leaves.After Dean and Sam rescue Lisa, Castiel comes to the hospital where the gravely injured Lisa is not expected to survive. He apologizes again, but Dean is not forgiving. Castiel says that he did not a come for Dean, then places a hand on Lisa's forehead, healing her. Both Dean and Cas acknowledge that this does not change their situation, but Dean asks for an additional favor. Castiel removes all Lisa and Ben's memories of Dean.Later Castiel finds and takes Dr Visyak, the creature he needs to open Purgatory.

In The Man Who Knew Too Much, Castiel and Crowley torture Dr Visyak until they obtain what they need to open Purgatory. She escapes and contacts Bobby and the Winchesters, telling her story before dying in an alley from her injuries. Castiel comes to the three hunters, who are outraged. Dean tries to argue with him again, but Cas cuts him off, saying he no longer cares about Dean's opinion. He then touches Sam's head, breaking the mental wall, and promising to repair him as long as Dean stops the opposition.

Castiel becomes a god

Castiel becomes a God with the souls from Purgatory.

Castiel meets with Crowley, who has assembled the necessary ingredients. The angel wants to renegotiate their deal. He will not give Crowley the souls, so Crowley can either flee or die. The demon leaves Castiel with the blood for the ritual. Later, Castiel confronts Balthazar. He says that Dean is coming, and someone among them is a traitor. Balthazar asks him who it is, and Castiel lies that he does not know, and wants Balthazar to investigate. While the other angel is distracted, Castiel stabs and kills him.Just before the ritual is meant to begin, a cloud of demons descends around the building, and Crowley appears. Castiel tries to kill him, but cannot. He has a new partner in Raphael. Castiel is surprised at the partnership with their differing goals, but both seem to think they have taken the best course available. They demand the blood; Castiel throws them a jar and leaves. Crowley conducts the ritual, and though Bobby and Dean try to interrupt, completes it.

Castiel god

Castiel declares himself as the new God.

Nothing happens and Castiel reappears. Crowley realizes that he switched the blood, and conducted his own ritual. Castiel displays his power briefly in a flash of energy. Crowley, realizing the game is up for the time being, wisely disappears, and Raphael asks for mercy.

But Castiel is not in a forgiving mood. He snaps his fingers, obliterating Raphael to pure dust in mere seconds. He turns to Dean and Bobby. He was right, he says, and he did save them. Dean nervously agrees, then suggests that Castiel should return the souls, and disarm himself. Castiel says he has Raphael's followers to deal with. Dean is worried, and reminds Castiel that he is family, and he doesn't want to lose him. Castiel says that he has no family anymore; he will not give up the souls.

Using that moment, Sam stabs him from behind with an angel sword, but nothing happens. Castiel greets him, then says the sword will not work because he is not an angel anymore. He says that he is their new God, and that they must venerate him, or be destroyed. As he says those words, Dean, Sam and Bobby look on in horror, realizing with shock that their former ally and friend has become a power-hungry villain who believes that he is God.

Season Seven

Powers & Abilities

Angel blade

Castiel using an angelic blade to kill an angel

Since his first appearance, Castiel possessed astounding abilities and was one of the most powerful beings the Winchester brothers have ever met at the time. Even when not at full strength, he is shown to be a very capable fighter due to him killing several of his angelic siblings when he was fighting to prevent the Apocalypse. Castiel displayed the following powers when he was a mere angel:

  • Invulnerability - Castiel has shown to be impervious to most forms of harm. In "Lazarus Rising", he absorbed several shotgun blasts directly to the chest. He even withstood the full force of the Demon-Killing Knife and simply pulled it out of his shoulder before dropping it to the ground. He is immune to all ailments and is immortal, able to fully heal from any non-supernatural wound almost any wound regardless of its fatality.
  • Angelic Possession - Like angels, Castiel can to possess a human to physically interact on Earth as long as he is given the person's consent. For Castiel, he is most comfortable while possessing a human of the Novak bloodline, in case, Jimmy Novak.
  • Telekinesis - Castiel has the ability to move objects and even people with his mind. He is also shown to be refined with this power to the point where he could inscribe enochian sigils on the ribs of the Winchester brothers' without breaking the skin.
  • Induced Sedation - By placing two fingers to their foreheads, Castiel can cause humans to instantly become unconscious as he did with Sam and Bobby.
  • Voice Mimicry - On one occasion Castiel perfectly mimicked Bobby Singer's voice.
  • Magical Healing - Like all angels, Castiel can heal humans. Castiel has saved and healed both Sam and Dean many times from their wounds.
  • Resurrection - Castiel can resurrect humans back from the dead as he has brought Dean, Sam, and Bobby back from the dead.
  • Teleportation - Castiel possesses the ability to transport himself and others to any location as long as the area is not protected by enochian sigils. Whenever he uses this power the sound of flapping wings and a sudden rush of air can be heard. But he can Teleport without hearing sound of flapping wings or a rush of air.
  • Superhuman Strength - Though he typically seems to attempt to avoid fighting, he is a very formidable physical opponent when need be, and is unstoppable when facing mortal beings. As Uriel exhibited superhuman strength when battling two demons in the episode "Heaven and Hell", Castiel most likely possesses such physical power as well. Also his strength has been seen in numerous episodes, and he is shown be quite strong. In the episode "On Head of a Pin" Castiel was able to send Uriel flying through a wall.
  • Killing Touch - He possesses the ability to kill or exorcise a demon simply by touching his palm to the forehead of it's host. But this does not work on demons stronger then Castiel as Alastair proved to possess complete immunity from such an attack.
  • Time Manipulation - Castiel also possesses the ability to bend time and teleport himself and another backwards through time. However, the further the he sends a person back in time the harder it is to retrieve them. For example in "Frontierland " he sends Sam and Dean back into the 1800's and says that he must bring them back within 24 hours, or they will be lost to him.
  • Astral Projection - Castiel also appears to be capable of projecting at least a portion of his true self from his host, as at the end of "Lazarus Rising", he was able to display the shadows of his wings to Dean as proof that he was in fact what he claimed.
  • Telepathy - Castiel can read the minds of humans and other angels. He can also enter and communicate with humans in their dreams using telepathy as shown with Dean.
  • Immortality- Castiel, like all celestial beings, is not subject to time, aging, or diseases, and doesn't need to breathe, eat, or sleep to sustain himself.

After Second Resurrection

After being killed by Lucifer, Castiel was resurrected by God and according to him was made stronger than ever before. It's unknown by how much his power increased by after his second resurrection, but it was shown that he was still no match against Raphael in a one-on-one fight. He was then shown to be more of a formidable match against Raphael when Crowley gave him 50,000 souls to increase his power. After his second resurrection, he displayed the following powers:

  • Soul-reading - Castiel displayed this ability to see that a boy had sold his soul to Balthazar and again to see how damaged Sam's soul was after it had been tortured in Lucifer's Cage. He used it to search Sam's body and later informed Dean that Sam's soul wasn't there, presumably because it was still in Hell.
  • Soul Channeling - Castiel displayed this ability to strengthen himself with 50,000 souls from Hell and again when he absorbed all the souls of Purgatory to evolve into a god.
  • Pyrokinesis - Castiel displayed this ability when he extinguished the circle of holy fire that trapped Balthazar.
  • Holy White Light - Castiel used this ability to kill several monsters at the same time.
  • Invisibility - Castiel used this ability to spy on Dean living a normal life and again when trying to see how much Dean, Sam, and Bobby have learned about his and Crowley's alliance.
  • Memory Manipulation - Castiel allowed Dean and Sam to keep their memories after Balthazar prevented the sinking of the Titanic.

After Absorption of the Souls of Purgatory

After absorbing all the souls of Purgatory, Castiel attained the powers of a god. Having ascended to a higher level of power, Castiel easily obliterated the Archangel Raphael by simply snapping his fingers, which in turn caused Rapheal's body to explode. (It should be noted that Raphael smote him in a similar fashion in Lucifer Rising.)

When Sam attempted to kill him by stabbing him in the back with an angelic blade, it failed to kill him, and Castiel stated that he was no longer an angel and therefore no longer shared their weaknesses. Because of this, it can be assumed that Holy Fire and the Angel Banishing Blood Sigils will have no effect on him.

After attaining godhood, Castiel has displayed the following new abilities:

  • Molecular Combustion - With a snap of his fingers, Castiel was able to speed up Rapheal's molecules to the point that it caused him to explode; similar to the way Lucifer killed Castiel.
  • Enhanced Invulnerability - After turning into a god, he is no longer vulnerable against angelic blades and probably any other angelic weaknesses.
