Douglas M. Carmody was in charge of the Carmody Research labs where Dr. James Power was working to perfect his anti-matter power generator. When the alien race of Kymellians destroyed the anti-matter generator (which also led to the creation of four young heroes known collectively as Power Pack) Carmody lost his position, blaming the children of Power Pack.
Carmody went on to hunt the Pack, whom he considered mutants. To this end, he stole a powerful battlesuit from the government energy research station, Project Pegasus, and called himself the Bogeyman. He later fought the Warriors Three of Asgard as well as the mutant students known as the New Mutants in his attempts to kill the Power Pack.
During a demonic invasion of New York City, N'astirh took several people and turned them into demons against their will and Carmody was one of these. Although most of these returned to human form later, Carmody was already so insane and demon-like before his transformation that his transformation became permanent. In his new form, Carmody tried once again to kill Power Pack and kidnapped their parents, but when he saw his new image in a window, he became irrational, jumping off a building.
The Bogeyman later resurfaced to torment Luke Cage.
