Pyro is a mutant.
Pyro was first seen as a captive of the Mutant Response Division. He and others were freed by Wolverine.
He later joined Magneto's Acolytes living in Genosha. Pyro and Senyaka were sent to MRD Facility Beta in the Northwest to break out several mutants. Polaris later mentioned to Magneto that Pyro informed her of Scarlet Witch's disappearance. While the other Acolytes searched for Nightcrawler and Scarlet Witch, Magneto placed Pyro in Nightcrawler's special cell stating to Pyro that he had done enough.
