History: McCoy is originally from an alternate timeline in which Apocalypse conquered North America and mutants rule. McCoy was the head geneticist for the horseman Mister Sinister, and ran Sinister's slave pens in the area that was once New York. McCoy experimented on numerous mutants, creating the Infinite Soldiers for Apocalypse's forces, and advanced his own mutations.

After Sinister's death and a rebellion in the Slave Pens led by that timeline's Cyclops, McCoy fled to Apocalypse's Citadel in New York City. In a battle with that timeline's X-Men, McCoy teleported himself into the M'Krann Crystal, which is a nexus of all realities, and vanished.

McCoy found himself in the "mainstream" X-Men's reality some twenty years in the past and settled in New York to continue his experiments. He has given himself credit for creating the Morlocks, but whether he has been telling the truth remains to be seen. During this time, McCoy sent his agent Random to ally himself with the government mutant team X-Factor. Random ambushed X-Factor, captured the team's then-leader Havok, and brought him to McCoy for experimentation.

McCoy then sent his agent Fatale to seduce and capture the X-Man known as Bishop, the only denizen of "mainstream" reality who remembered the alternate timeline which McCoy hailed from. McCoy hoped to erase all memory of his original timeline by eliminating Bishop. Bishop escaped from Fatale with help from this timeline's version of Henry McCoy, the X-Man known as the Beast. During the fight, McCoy discovered that he had a counterpart in this timeline who was a member of the X-Men.

In order to infiltrate the X-Men and capture Bishop, McCoy kidnapped Beast and altered his own form to resemble Beast. McCoy was uncovered as an impostor by the entity known as Onslaught when the latter attacked the X-Men, and McCoy escaped. McCoy was eventually driven off by X-Factor, who had found and rescued the "real" Beast. McCoy was found and rescued by Havok, who had since escaped McCoy's control, and recruited McCoy into the reformed Brotherhood of Mutants.
