History: Thousands of years ago, a long since forgotten civilization worshipped their demon-god Nebiros. The priests breached the void between his dimension and our own, unleashing him on the world. In exchange for sacrifice, he led their armies in an attempt to conquer the world. Eventually Neibros’ empire grew to threaten the great empires of Mu, Lemuria and Atlantis. The greatest magicians of these realms banded together and banished him back to his own dark dimension.

(Swamp Thing I #15) - Father Jonathon Bliss’ congregation left him, and he went mad when he couldn’t force them to behave as he believed good Christians should. He entered the world of black magic, and summoned up Nebiros, who promised to start a war that would bring about Armageddon and force people to turn to god for help. Bliss believed god would surely return to save his people, but Nebiros knew he was playing Bliss for a fool. Nebiros’ otherworldly form had to be stored in a transcendental globe pending a suitable host to inhabit. Bliss befriended Swamp Thing, and lured him into a false sense of security, and then performed a spell that let Nebiros inhabit his body. Nebiros, in Swamp Thing’s form, captured Swamp Thing’s friends Abby Arcane, Matt Cable and Luke, and ripped out Luke’s soul for fun. Matt made Bliss see the error of his ways in playing god, and Bliss tried to exorcize Nebiros, but the demon was too powerful. Matt escaped his bonds and destroyed the transcendental sphere, casting Nebiros from Swamp Thing’s body. Nebiros and Swamp Thing fought, but Nebiros’ otherworldly form could not sustain itself on the earthly plane without a host. Bliss offered himself up, but he was too weak a vessel, and was incinerated. Bliss knew full well what he was doing, and Nebiros’ consciousness was scattered across the universe.
