In "Ultimate X-Men" #78, Xavier is apparently killed by Cable who was trying to prevent the horrible events in the future. In "Ultimate X-Men" #80 it is revealed that he is in fact alive, and a captive of Cable in the future. It has also been revealed that Cable has repaired his spine and is training Xavier to fight against Apocalypse. However, once the battle came, Jean Grey manifested as the Phoenix and destroyed Apocalypse. Jean returned everything back to normal, giving Xavier a "fresh start". As she did so however, she undid the repair to his spine that Cable had performed, leaving him once again crippled. Xavier reformed the X-Men upon return as the Headmaster of the Xavier Institute.
