The Demon is a DC Comics superhero series create by prolific comic book writer-artist Jack Kirby. The title character, named Etrigan, is an actual demon from Hell who, despite his violent tendencies, usually finds himself allied to the forces of good, mainly because of the alliance between the heroic characters of the DC Universe and Jason Blood, a human to which Etrigan is bound. Etrigan resembles a squat, muscular human with orange (or yellow) skin, horns, red eyes, and ears resembling bat wings. Blood is a tall, thin, suave man with dark red hair and a lined face.
