The Days of Future Past storyline was adapted in the X-Men animated series. The storyline concepts were combined with another alternative future story—that of Bishop and the idea of a traitor within the ranks of the X-Men. Bishop plays the role of Kitty Pryde. The future is a dystopia where Sentinels rule, and mutants are put into concentration camps. Only a small group of mutant rebels remain free and unharmed, led by an aged Wolverine. Bishop, a bounty hunter, captures Wolverine, but sides with him when the Sentinels attack him as well. They meet Forge, who has created a time machine and sends Bishop back in time to change history by preventing the assassination of Senator Kelly. He identifies Gambit as the assassin, but the crime was actually committed by the shape-shifting mutant Mystique, who took the form of Gambit to frame the X-Men. The real Gambit saves Kelly, and Rogue sends Bishop back to the future by destroying the time band that allows him to stay in the past. However, Bishop returns to a future that is still a dystopia. Bishop would return several times to prevent other villains from changing history in even worse ways, but never managed to prevent the Sentinel takeover. Unlike in the original story, whirlwinds would come to "correct" Bishop's present based on events in the past, whereas the original story followed the parallel universe theory of Reed Richards.
