Today's Fact
Everyone else woke up in Apocalypse's world believing it had always been that way — one time traveller's scrambled memory said otherwise.
In "Legion Quest," David Haller travelled back in time to kill Magneto and instead killed his own father, Charles Xavier — and reality rewrote itself around the murder. The X-Men who had chased Legion into the past vanished along with the world they came from. Bishop did not. Because he was already a traveller from a divergent future, he stood outside the change: a chronal anomaly the rewrite could not digest.
Surviving cost him twenty years and most of his sanity. Thrown forward into the new timeline — the Age of Apocalypse, where Apocalypse had conquered North America — Bishop wandered it for two decades with his memories of the true history fragmenting in his head, insisting to anyone who would listen that the world was wrong.
When Magneto's X-Men finally found him, his fractured recollections became the rebellion's most dangerous weapon: proof that another world had existed and could be restored. Magneto had Destiny verify the story, then staked everything on sending Bishop back to stand between Legion and Xavier — restoring the timeline at the price of erasing the only world those X-Men had ever known.
Why It's Obscure
Bishop has hunted traitors, babies and futures — but his strangest assignment was remembering one for everybody else.
