John Constantine

John Constantine is the title character in the Constantine series and part of the Arrowverse fandom.

Character
John Constantine is a man waging war against the forces of darkness — from both within himself and the outside world. An irreverent, working-class con man and occult expert, he’s an experienced exorcist and demonologist with an extensive list of supernatural contacts, with their own paranormal talents and abilities.

Following the aftermath of a tragic incident, Constantine has voluntarily checked himself into an asylum and sworn off investigating matters of the supernatural. But when a cryptic message calls him out to reluctantly resume his old life, he finds himself allying with Manny, a rogue warrior angel, and Chas, Constantine’s giant childhood protector — the only friend who’s managed to stay alive.
