Daimon Hellstrom and Gargoyle likely owed some creative debt to The Demon, a series that Jack Kirby created for DC Comics soon after leaving Marvel.
The debut issue introduced readers to Jason Blood, a demonologist with a conspicuously long lifespan. During one of his supernatural investigations, Jason entered a crypt protected by living gargoyles.
Within the crypt, Jason felt compelled to read aloud a mystic inscription that would cause him to involuntarily change back and forth into the demon Etrigan.
Although Etrigan had previously served Merlin the magician and continued to fight against the forces of evil, Jason largely despised transforming into the inhuman creature.
