Nothing is known about the Reanimator, save that he was a technopathic mutant with a flair for the overdramatic who used his powers to fashion armies of robots in the rough shapes of other superhumans to commit crimes for him. He also apparently considered himself the archnemesis of Nova (Richard Rider).
When Nightcrawler and the Skrull sleeper agent impersonating Wolverine tracked what was apparently their old nemesis Magneto to an old junkyard, they were attacked by the Reanimator's robots, and quickly deduced that "Magneto" had also been one of them.
