Fictional team of supervillains
Cerebro's X-Men are a team of supervillains appearing in American comic books published by Marvel Comics. They are a nanotechnology version of the X-Men created by Cerebro when the supercomputer briefly goes rogue.
This team was created and designed by the Spanish artist Carlos Pacheco, who also drew them for the cover of "Uncanny X-Men" No. 360 (1998). The characters appeared in two issues of the "Uncanny X-Men" series and one issue of the "X-Men" series. The team's primary purpose is to help Cerebro catalog all mutants on Earth, but Cerebro intends to cryogenically preserve the mutants it captures and its team kidnaps and fights other mutants.

Fictional team history.
Cerebro, a device created by X-Men founder Charles Xavier to help locate mutants with the X-Gene, is confiscated by the mysterious Bastion during . Bastion attempts to access secret files and operate Cerebro, but the supercomputer activates a computer virus to erase this information rather than letting it be stolen. However, the combination of Cerebro's power with Bastion's nanotechnology gives the supercomputer sentience. Cerebro creates a body for itself, escapes Bastion's headquarters, and tries to follow its original programming literally: find, catalog, and register mutants. However, a large part of its plan to catalog mutants is to capture and store them in cryogenic chambers for further study. Cerebro begins its new mission by creating its own version of the X-Men, Professor X's team. It manages this by using Bastion's nano-technology to combine the profiles and powers of several mutants in Professor X's database to create new mutants. Then Cerebro takes on Xavier's appearance, posing as the renowned mutant leader ato invite each new mutant to join its team under the guide of "The Founder," and sets them a mission to kidnap Peter Corbeau, a scientist working on mutant defense technology for the US government. After Corbeau is captured, Cerebro's X-Men are then sent to find Kitty Pryde/Shadowcat, who the disguised Cerebro asks to "cure" him. Shadowcat manages to phase out Bastion's virus, though she doesn't know exactly what she's done because she thinks Cerebro is the real Professor X. Cerebro then orders its X-Men team to place her in cryogenic storage, so her DNA will be preserved for future study.
Shadowcat manages to escape and finds Wolverine, Rogue, Storm, Colossus, Nightcrawler, and Marrow, who had been searching for her. Eventually they encounter Cerebro and his X-Men, who are attempting to destroy the government's mutant tracking satellite, regardless of the potential threat to human life once its radioactive core is breached. Wolverine's enhanced senses confirm Shadowcat's suspicions that this "Xavier" is an impostor, and the real X-Men realize that if Corbeau's satellite is launched, then Cerebro won't be collect mutants before humans find them. The real X-Men fight and defeat Cerebro's X-Men, preventing the satellite from exploding.
Cerebro escapes the lost battle and reveals their true origins to its X-Men team before deeming them failures and absorbing them into its own body. By doing this, it becomes an even more powerful cybernetic monster, and only the real Charles Xavier is able to subdue Cerebro, purging its systems and destroying the superpowered robotic body it had created.
