Castiel is a main character from Supernatural.
Castiel, an angel of the Lord, was responsible for pulling Dean Winchester out of Hell, on God's command. According to him it was his job to help prevent Lilith from breaking the 66 Seals that, once broken, would release Lucifer from his cage. In reality Castiel, like all the other Angels, wanted to free Lucifer to start the Apocalypse. Eventually, he joined the Winchesters' cause but not before helping Sam Winchester break the last seal by releasing him from his cell.
