Dark Cerebro is a copy of Cerebro built by William Stryker in his Alkali Lake base using the data stolen from the X-Mansion's computer.


Stryker uses his son, Jason Stryker, to force Charles Xavier to activate this device in order to target and kill all of the mutants on the planet. However, Magneto later arrives and uses the setup so that Xavier kills all of the humans on the planet instead. Later, Storm and Nightcrawler arrive and rescue Xavier as the base is destroyed in a flood.
