Elliot was thought to have killed his parents as his mutant powers emerged. The police said he killed them but Elliot tried to deny, soon finding himself in a grassy plain. He was then found by Nick Fury, who orders him to come into S.H.I.E.L.D. custody. It took a lot of effort to subdue him, as he was afraid of what he heard that happens to mutants. Fury brings the boy to Xavier's to be observed and trained in the use of his power; the other option was to keep him under lobotimization. Elliot quickly worked his way into the core group of the X-Men and even joined in a mission to the Academy of Tomorrow, where the Brotherhood attacked during the school dance.
During his absence from the mansion, Nick Fury talked to Xavier about taking Elliot "Magician" into SHIELD custody. Xavier informed Fury of how Elliot arrived at the mansion and the scope of his power has been revealed. Upon arrival of the group Xavier informed the team of Elliot's actions and the team attacked Elliot. During the fight Elliot exhibited more of his power by creating instances of Multiple Man, Blob, and Toad of the Brotherhood to attack the X-Men. At the conclusion of the battle Wolverine drove his claws into Elliot's chest presumably causing his death.
At the end of the day Elliot is shown talking to Kitty about his power and potential and that he is not really dead, but chose to disappear and try to learn control of his power. This was done only for personal reason as Kitty never really saw or heard Elliot.
