The Demon is a fictional character, a superhero appearing in comic books published by DC Comics. Created by Jack Kirby, the titular character, named Etrigan, is a 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.[1] 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. The character was originally based in Gotham City, leading to numerous team-ups with Batman.
Etrigan was inspired by a comic strip of Prince Valiant in which the titular character dressed as a demon. Kirby gave his creation the same appearance as Valiant's mask.

History

He was originally summoned by the wizard Merlin as part of a last-ditch defense of Camelot against the evil witch, Morgaine le Fey. When it became clear that the kingdom would fall regardless, Merlin sent the demon away and bonded him into a human named Jason Blood to wait until he was summoned.
Centuries later, Jason was called to the crypt of Merlin and discovered a poem that could change him into Etrigan. Unfortunately, he was followed by the long-lived Morgaine who lusted for Merlin's secrets. That led to Etrigan's first major battle, and to the solidification of Morgaine as a major enemy. In addition, he later gained another enemy in Klarion the Witch Boy, a permanently prepubescent mage who created trouble with his magic.
Some time later, Etrigan began speaking entirely in rhyme, as the result of a promotion, with the rhyming speech being a badge of his new rank in the infernal hierarchy.
The poem that released Etrigan was:
Jason Blood's first transformation into the Demon occured when reading the inscription on the surface of a stone tomb:Yarva Demonicus Etrigan.Change, change the form of man.Free the prince forever damned.Free the might from fleshy mire.Boil the blood in heart of fire.Gone, gone the form of man,Rise the demon Etrigan!
Change! Change,O' form of man!Release the might from fleshy mire!Boil the bloodin the heart for fire!Gone! Gone! -- the form of man --Rise, the Demon Etrigan!!


After emerald archer Green Arrow's resurrection, Batman and Oliver recruit Blood for his occult knowledge as to how Oliver could have been resurrected. It is found that Oliver is a Hollow - a soulless husk of a human, created by Hal Jordan with the Spectre's powers to soothe his guilt. Blood called on Etrigan to kill Oliver (being a Hollow left him vulnerable to possession, which could have been very bad). He was stopped in his attempt by a Fire Extinguisher Arrow. Batman, in response to the unusual weapon said, "I will never ever mock your trick arrows again."
