Castiel

**Castiel**, often shortened to **Cass**, is a powerful angel of the Lord who was responsible for saving Cameron Winchester. from Hell, on the archangels' command. It was his job to help prevent Lilith from breaking the 66 Seals that, once broken, would release Lucifer from his cage in Hell. Once Castiel learned that the angels wished to free Lucifer anyway, he defied his angelic brethren and died trying to help Cameron prevent Adrian Winchester from breaking the last seal.
Castiel had a one night stand with Genevieve, as a vessel of Asher, and created a Nephilim Kayleigh.

After he was killed by the Archangel Raphael, Castiel was resurrected by God and joined Adrian, Cameron, and Bobby Singer in a quest to prevent the brothers from becoming the vessels of Michael and Lucifer. Castiel would later be killed by Lucifer but his actions allowed Adrian to trap both Archangels away. With the Apocalypse averted, Castiel was again resurrected by God with new powers, being promoted to Seraph. He then started a civil war in Heaven to prevent Raphael from restarting the Apocalypse, Believing he could not be outsmarted by a demon, Castiel teamed up with Crowley to claim the souls of Purgatory. He ended up betraying Crowley and absorbing all the souls, resulting in his powers reaching a level much higher than that of an archangel, but at a high price: the powers that the evil souls granted him had went to Castiel's head, causing him to proclaim himself as the new God.

As his body started to rot, Castiel later agreed on the advice of Cameron to release the souls back into Purgatory. While seemingly successful, it turned out that the one of the most powerful entities from Purgatory, the Leviathans, held on to Castiel, and overpowered and took control of him. When the Leviathans left to take over new forms, Castiel was presumed dead, but survived – apparently resurrected by God yet again. Cameron later accidentally finds Castiel as an amnesiac healer called Emmanuel. After taking on Adrian's madness and experience in Hell in order to save the Winchesters and redeem himself for what he did to Adrian, Castiel had become insane and fell into a coma. However, he awakens and his sanity is returned to an extent when a signal was sent to all angels upon the discovery of the Word of God and the appointment of a new prophet. He then aids the Winchester brothers against Dick Roman, only to be transported to Purgatory with Cameron.

While Cameron comes back, Castiel has not returned with him. While his condition is initially unknown, it's revealed that he spent most of his time running from Leviathans and that he didn't escape Purgatory with Cameron as he had planned to stay as a form of penance. However, he was eventually released from the monster realm by an incursion of angels under the orders of a mysterious but powerful angel named Naomi, rejoining the Winchester brothers and trying to become a hunter himself. But after a long while, Castiel learned that Naomi had been controlling him ever since she got him out of Purgatory and compelling him to find the angel tablet, at any cost, even going as far as killing Cameron. After he almost did so, Castiel then teamed up with Metatron when the angel convinced him to help him close the gates of Heaven. So after collecting the heart of a nephilim and the bow of cupid, Metatron is eventually captured by Naomi but escapes and kills her, only for Cass to discover Metatron's betrayal and plan to cause all angels in Heaven, even the imprisoned ones, to fall to Earth.

After being stripped of his grace by Metatron in order to expel all angels from Heaven, Castiel spends the next three months on Earth as a human. After being captured and tortured by an angel named Malachi, Castiel steals the grace of Theo and returns to his original status as an angel (previously being promoted to a Seraph). Castiel later assists Cameron with expelling the angel Gadreel from Adrian and heals Adrian's wounds. After Cameron leaves with Crowley to find a way to defeat Abaddon, Castiel also leaves to begin a search for Metatron and Gadreel while being pursued by other angels, and eventually killing rebel leader Bartholomew, he assumes command of his faction. However, a deception of Metatron's makes him lose his army; instead he teams up with angels Gadreel and Hannah to infiltrate Heaven and destroy the angel tablet, cutting off Metatron's power to allow Cameron to kill him. Though successful, Cameron and Gadreel are killed, while Castiel locks Metatron up. He then left Heaven as he didn't want to be a leader and was dying due to his burning-out grace before Crowley saved him with Adina's grace. He has since reclaimed the last of his own grace and restored to full power and being a Seraph once again.

After the release of the Darkness and the trauma he suffered under Rowena MacLeod's spell, Castiel agreed to act as the vessel for Lucifer to walk the Earth once more so Lucifer could battle the Darkness. Castiel would remain Lucifer's vessel for months, only emerging briefly to save Adrian's life and convince the angels to help against the Darkness. At the end of the conflict with the Darkness, Lucifer was exorcised from Castiel by the ancient being, leaving Castiel in control of himself once more. During this time, he finally found God, who returned to defeat the Darkness as well.
