At some point in the world Charles Xavier awakes in a post apocalyptic future where Sentinels now rule and mutants and humans are both nearing extinction. Following his capture Xavier encounters Bishop in a mutant internment camp. To Bishop's surprise, the old man is the Charles Xavier that Wolverine had always talked about.
According to Bishop, Wolverine was captured and never heard from again, presumed dead. Although it is later revealed that he was alive with a team of X-23 clones. He later rescued Xavier and the others. When asked what happened in the past that caused this future, Wolverine replied by saying they couldn't get Jean back and then he said I was the flaw and not wanting to go any further. Due to this it is not known what did cause this future since the present day timeline was saved. He later lead the final battle against Master Mold.
