Mr. Vayle hires the "investigators" Xavier's School, to find out about the hauntings Museum (which he hardly knew "hauntings" were nothing more and nothing less than Alistair). The X-Men Beast and Iceman meets Alistair, after dinner he steals Hank (Beast), Hank and Bobby (Iceman) invite Alistair to join the X-Men, but he rejected saying he had no attribute to offer them.
