Uncanny X-Men #360 (1998)
The team's first mission was to kidnap the X-Man Kitty Pryde in order to use her computer skills to extract a virus from Cerebro's systems. They were successful although she escaped before she could be stored in cryogenics.
The team soon defeated the real X-Men in combat and believed them to be destroyed; their attentions soon turned to a government satellite created to detect and destroy all mutants from space. The team soon began their mission to destroy the satellite's nuclear reactor (despite the surrounding civilians) and use the satellite's tracking system in order to track down every mutant for capture and catalogue.Although it seemed that Cerebro's X-Men were going to succeed in their task; it was not long until the real X-Men arrived to stop them. After their defeat and Cerebro's identity revealed the team regrouped in confidence that Cerebro would forgive them; Cerebro instead decided that it was nessercary to absorb its team into its body in order to gain enough strength to defeat the real X-Men, although not before expressing its feelings for them first.
