X-Factor

After events on Muir Island, the original members of X-Factor, who were also the original members of the X-Men, rejoined the X-Men. Feeling a need to continue a separate, but government-affiliated mutant team, Professor Charles Xavier and Cyclops traveled to Genosha, where Cyclops' brother, Alex Summers (Havok), was working. Havok was recruited to lead the team, and X-Factor was restarted as a new government-sponsored team, with Val Cooper acting as government liaison. Wolfsbane, Polaris, Strong Guy, Multiple Man, and Quicksilver filled out the original roster.

One of the first villains the team faced was Mister Sinister and his lackeys, the 'Nasty Boys'. Sinister hoped to discredit the mutant kind and used X-Factor to do so. One of Sinister's behind-the-scenes allies was a power-hungry Senator with the power to cause bad luck. Strong Guy was manipulated into destroying the Washington Monument while fighting Slab, one of the Nasty Boys. The Senator, who was after the entirety of the X-Factor team, was later slain by Mr. Sinister himself.
