What happened to X-Factor?
The original X-Factor members rejoined various incarnations of X-Men, while the X-Factor kids generally became members of the New Mutants, X-Force, or Generation X. Alex Summers (Havok) was a member of X-Factor after the original X-Men left. Havok presided over that team and was going to reorganize it after their ties with the government were broken. Summers enlisted Shard, Polaris, Multiple Man, Fixx and Greystone into his new X-Factor, only to have the team go nowhere because Marvel used X-Factor #149 to ignite a new series, MUTANT X. In the fateful issue, Greystone (who, like Fixx and Shard, was a member of the XUE from Bishop’s timeline) attempted to return to his own timeline. The plan backfired, and the plane carrying him and Havok exploded. Havok was sent to the Mutant X world, inhabiting the body of that alternate universe’s Alex Summers when he “died.” He appeared in the Mutant X title until it was cancelled. He was seen apparently floating in Limbo after he “died” in Mutant X
