Originally mistaken to be the real Magneto, even eventually believing so himself, the young man called Joseph first appeared in Middle America when he was taken into an orphanage by Sister Maria after being found feverish and exhausted. With no memory of his past life he was named Joseph by Migdalia, one of the orphans. After Sister Maria and the orphans were being held hostage in an attempt to force Joseph to work with a criminal organisation, Joseph attacked the organisation and killed several men to rescue the sister and the orphans, who were shocked and apalled by what he had done. He left the next day and was told by Sister Maria to seek out the X-Men. He wandered Middle America until encountering Rogue who convinced him to return with her to the X-Men. Joseph aided the X-Men against such threats as Onslaught, and these acts gained Joseph the X-Men's trust. The real Magneto has since returned, albeit not to the X-Men's knowledge, and the truth about who Joseph really is has yet to be revealed.
