The Demon is a DC Comics superhero series created 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 whom Etrigan is bound. Etrigan resembles a squat, muscular humanoid creature 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.
Etrigan was inspired by a comic strip of Prince Valiant in which the title character dressed as a demon. Kirby gave his creation the same appearance as Valiant's mask.
Jack Kirby created The Demon in 1972 when his Fourth World titles were canceled.
