History: Martin Preston was a rich and successful Hollywood actor who ran his car off a cliff while drinking and driving one night. Preston lost his right arm in the fall, and was hanging upside down by his seatbelt when the demon Mephisto appeared in answer to his screams of agony. Preston offered Mephisto his soul in exchange for having his arm restored to him. Mephisto agreed, and summoned a lesser demon, wrenched off its arm and magically attached it to Preston's shoulder stump. Preston lost consciousness in the process, and was insensate when Mephisto severed his uninjured left arm and replaced it with a demon's arm, as well.

There are as yet no accounts of Preston's activities following his acquisition of demonic arms and his first encounter with the West Coast Avengers. It is known that he adopted the name Master Pandemonium (pandemonium meaning "abode of all demons") and purchased the Anvil Pictures movie studio where he once worked. Master Pandemonium's chief preoccupation is the locating of "The Five," five demons who have special significance to him. Master Pandemonium believed the fledgling superhuman champion Firebird was one of The Five and attacked her. Determining she was not, he ordered his demon arms to defeat her, and then left. Firebird went to the West Coast Avengers for aid in finding him and they agreed to help. When Master Pandemonium and his demon hordes attacked the Thing, in an attempt to determine if he was one of The Five, the West Coast Avengers arrived to combat him. He managed to hold them off by summoning his horde of demons and escaped.

Later the West Coast Avenger named Tigra was given the task to slay Master Pandemonium by the mystical other dimensional Cat People. The Cat People considered Pandemonium a threat to their existence and wished Tigra, the mythic warrior-woman of their people, to end the menace. Tigra got a chance some time later, when the West Coast Avengers tracked Master Pandemonium to his motion picture studio, but he managed to elude her. The West Coast Avenger, Mockingbird, clad in the guise of a demon, tricked Pandemonium into revealing certain secrets of his origin.

Much later, Pandemonium confronted the West Coast Avengers again, claiming that the twin sons of the Scarlet Witch were actually soul fragments transformed into her sons by the Scarlet Witch's spell/hex combination she used to allow herself to become pregnant. He clashed with the Avengers, but managed to destroy the twins to revive part of himself anyway. Agatha Harkness and the original Human Torch somehow retrieved the remaining two soul fragments Pandemonium needed, and once in place, Pandemonium disappeared, to be replaced by Mephisto. The demon revealed the truth about his plot, seemingly destroying Pandemonium while fully reconstituting himself. The Avengers soon escaped from Mephisto's presence.

Known Superhuman Powers: Master Pandemonium's body is a dwelling place for a horde of demons, the exact number of which is unknown. How his body contains these mystical entities is not known; while it is possible they all literally exist in miniature form inside his body, it is equally possible his body is a nexus to a mystical dimension where the demons reside. There are two demons in particular who serve as his arms. They can be detached at command, leaving Master Pandemonium armless. When detached, they regain their full demon bodies. Master Pandemonium has a hole in his chest in the shape of an inverted five-pointed star, which he claims is the mark of his missing soul. An object or fist can pass through this hole without causing injury to him.

These demons apparently confer upon him their magical powers while they are inside him. Master Pandemonium can expel mystical fire from his mouth, apparently capable of melting the outer layer of Iron Man's armor. He can also project rays of a magical concussive force from his hands. He may have other supernatural capacities as yet unrevealed.

Weapons: Master Pandemonium wields the Amulet of Azmodeus, a mystical power object. It enables him to teleport himself and an undisclosed amount of additional weight. The maximum distance he can travel in one jump is not yet known.
