History
The X-Men's history seemingly resembled the history of their Earth-10005 counterparts and possibly their Earth-TRN414 counterparts, but it eventually diverged at an unknown period of time. Their leader, Professor X, was suffering from Alzheimer's Disease and underwent a seizure that caused his telepathy to go out of control, killing a number of the X-Men. This eventually forced the X-Men to disband and the school to close.[1]
