When the human-Sentinel gestalt Bastion stole Cerebro from the X-Mansion, Cerebro was hybridized with Bastion's programming via nanotechnology. The resulting entity, a self-aware form of Cerebro, created two minions, Cerebrites Alpha and Beta, through which it would act without exposing itself. It also used its Danger Room-derived records of the powers of the X-Men and the Brotherhood of Evil Mutants to create its own team of imposter "X-Men" whose members possessed the combined powers of specific members of each of the two teams. Cerebro's goal was to put human beings in stasis so that mutants could inherit the Earth, and to this end it hunted down a group of synthetic children called the Mannites who possessed vast psychic powers. It was destroyed by the X-Men, with the help of Professor X and the Mannite named Nina.
