Before they became heroes in Marvel Comics Super Special #1, the founding members of the rock band KISS materialized from a young woman under psychiatric supervision.
Called to investigate, Daimon Hellstrom determined that evil forces were not responsible for the unusual occurrence. Rather, the young woman had latent psychic talents that may have caused her to tap into a parallel universe. But Hellstrom assured doctors that the phenomenon was unlikely to reoccur (Howard the Duck #13).
Convinced nonetheless that the young woman was possessed by evil spirits, the misguided Revered Yuc kidnapped her. When Hellstrom came to the rescue, Reverend Yuc mystically removed the hero's chest pentagram and demonic powers. Hellstrom was relieved at first, until he saw that emblem unexpectedly branded on Howard the Duck (#14).
Along with Hellstrom's pentagram, mystic trident, and superhuman powers, Howard also inherited a volatile personality hellbent on retribution (which Hellstrom struggled long to control as the Son of Satan).
Hellstrom chased after the demonically driven duck, and then grabbed the mystic trident from Howard's hands, returning things to normal (or rather, as normal as they had been).
