Magneto's history is presumably similar to his Earth-616 counterpart's. During a mutant protest against a bill that requires mutant registration Magneto took part in, a fight broke out with the Squadron Supreme. During the fight, Power Princes killed Professor X and paralyzed Magneto after hitting him in the spine. Saddened by Xavier's death, Magneto vowed to aid mutants against human oppression. He set up the mutant sanctuary of Island M and founded the Mutant Force to aid him.
On the anniversary of Xavier's death, Magneto received a telepathic message from Xavier and realized that a part of Xavier's psyche remained in his own mind. To free Xavier, Magneto and the Mutant Force broke the telepath Emma Frost from imprisonment so she could use her telepathy to free Xavier's psyche from Magneto's mind. While Frost went about helping Magneto, the Squadron Supreme attacked Island M after tracking the Mutant Force there. Frost eventually left Magneto while she went to aid Island M's inhabitants against the Squadron. Magneto realized too late, however, that what he thought was Xavier in his mind was actually Xavier's evil twin sister Cassandra Nova. She had previous been in Xavier's mind but went into Magneto's when Xavier was killed. Nova then took over Magneto's body, killing Magneto. With her new body, Nova's first act was to banish the Squadron from Island M.
