Known Powers

Immortal human with knowledge of mysticism capable of transforming into a demonic alter-ego with superhuman strength, speed, agility, stamina and durability with sharp fangs and claws and an ability to emit mystical flames from the mouth.

Blood and his alter-ego are able to cast mystical spells and sense the past and future of others they encounter.

Blood or others with mystical talents can initiate the transformation by reciting the spell, "Change! Change! Transmogrify! Free the might from fleshly mire! Boil the blood in heart of fire! Gone, gone the form of man! Rise the Demon Etrigan."

First Appearance
The Demon Vol. 1 #1 (Aug. - Sept. 1972)
Jack Kirby

The last defender of Camelot against supernatural forces lead by the sorceress Morgaine Le Fey, the wizard Merlin unleashed a demon from hell. Although Etrigan wreaked havoc against the enemy, Camelot fell. Knowing he could not control the demon, Merlin cast a spell transforming Etrigan into a human.

Etrigan's human form lived through the centuries, apparently unaware of his demonic nature and would eventually settle in Gotham City under the name of Jason Blood.

Etrigan resurfaced to battle Morgaine Le Fey and other mystical menaces. Blood at first feared and despised his demonic self, but in time accepted his nature and has attempted to bring about a partial integration of his two personalities.

At times Etrigan serves as a hero and other times as a villain, but ultimately his goals appear to be the same as Jason Blood's, the destruction or domination of their alter-ego without destroying themselves.
