The Scorpio Comet was a comet that was passing near Earth. It was initially a harmless scientific curiosity. The mutant Magneto learned of the comet and formulated a plan. He intended to divert its path so it would head towards Earth killing most of the humans. He would then rule the survivors. He sent Blob and Pyro to the Deep Space Observatory to get the coordinates and distract the X-Men. Meanwhile, he and Juggernaut would attack the Xavier Mansion.
