Uncanny X-Men #363

« The Hunt for Xavier! Part Three: When You’re Unwanted »: In San Francisco, both a sentient robot called Cerebrite Beta and the X-Men search for Professor X, the machine abandoning a latent mutant to pursue the team once Cerebro detects them. Wolverine tracks Xavier’s scent to his abandoned, damaged wheelchair and signs of a fight. In Utah, another Cerebrite steals experimental nanotech from Bastion’s Area 52. Led by a mystic old friend to Alcatraz, the X-Men are ambushed by a new Brotherhood of Mutants using eerily familiar fighting moves — until Professor X himself intervenes, revealing he has been training them as allies against their true enemy: a newly sentient Cerebro, just as its agent bursts through the wall.
