You know, I've... I've been here for a very long time. And I remember many things.
|~ Castiel praying to God|
Castiel, often shortened to Cas, is a powerful angel of the Lord who was responsible for saving Dean 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 Dean prevent Sam Winchester from breaking the last seal.
After Raphael killed him, Castiel was resurrected by God and joined Sam, Dean, and Bobby Singer in a quest to stop both Heaven and Hell to prevent the brothers from becoming the vessels of Michael and Lucifer. When the Apocalypse was averted, he was again resurrected with new powers, being promoted to Seraph. He then started a civil war in Heaven to prevent Raphael from restarting the Apocalypse, Thinking a demon could not outsmart him, Castiel teamed up with Crowley to claim the souls of Purgatory. He ended up betraying Crowley and absorbed all the souls, resulting in his powers reaching the level that is much higher than an archangel, but at a high price: the powers that the evil souls granted him had warped Castiel's mind, causing him to proclaim himself as the new God.
Castiel's legacy has seemed to have become legendary among angels and demons alike, as many recognize him as the only angel who defied God's rules and cooperated with humans on his own decision, which he is either loathed or respected for. He is also the only angel to have been killed and been resurrected multiple times. He is the only known angel who has repeatedly been resurrected by God so he could help Sam and Dean Winchester.

Note 2: After regaining his grace at the end of Season 10, Castiel is still greatly weakened both physically and mentally due to various hardships he's been through. Some of these hardships are: Falling from heaven, dying several times, absorbing Sam's madness, fighting monsters for a year in purgatory, living with the guilt of him ruining heaven and killing thousands of his brothers and sisters, getting brainwashed by Naomi, being manipulated by Metatron, and being under a spell that affects his sanity.
