John Constantine

John Constantine is an exorcist, demonologist and petty dabbler of the dark arts. As a teenager, Constantine was brought into the occult world by Anne Marie. Constantine once summoned Nergal to save Astra's soul but the latter ultimately was damned to hell, an event which haunted Constantine for life.

Early life
When John was born, his mother died in the process, causing his father to call him a killer all his life.

During Constantine's teenage years, he met Anne Marie, who introduced him into the occult world. John then began reading every book he could find on the occult, learning how to conjure dead beings to one day conjure his mother.
