Etrigan the Demon

In the main DC continuity summarized by the provided sources, Etrigan is an infernal being summoned from Hell by the wizard Merlin. Because Merlin could not extract all of the demon's secrets, he bound Etrigan to the human Jason Blood, producing a single shared body and making Blood immortal. Sources note Etrigan is described as a son of the demon Belial in this continuity; origin details and continuity specifics have varied in different reboots and adaptations, but the core motif in the cited material is that Merlin's summoning and binding tie the demon's earthly activity to Jason Blood.

Depicted consistently in the cited sources as a muscular, horned humanoid with orange or yellow skin, red eyes, and pointed, sometimes webbed ears. Visual portrayals across comics and animated resources present him as a physically imposing, superhuman infernal warrior figure.

Across comics and animated adaptations cited in the notes, Etrigan displays supernatural powers including great strength and magical abilities; some adaptations (DCAU resources) attribute pyrokinesis and enhanced physicality to him. He is immortal in the sense common to demons in the fiction, while Jason Blood becomes immortal through the bond. Narratively he can be separated from and remerged with Jason Blood (separation has been shown to have consequences such as bodily aging for Blood). He sometimes speaks in rhyme, a distinctive behavioral trait in many portrayals. Story arcs also depict him attaining rank or influence within Hell (examples include promotion in Hell, leading forces of Hell in particular conflicts) but those are presented as plot events rather than a fixed bureaucratic office.
