Dark Beast
They arrived ten years after the X-Men had defeated Mister Sinister, yet it appears that the X-Men still face enormous challenges in this harsh setting. As they follow Dark Beast, unknowingly followed by Wild Child and Sabretooth, to one of his labs, Dark Beast approaches one Gatekeeper, who reveals that no one has ever entered the lab after Dark Beast's disappearance. As they walk in they find a picture with Sinister, Dark Beast, Havok and Cyclops on it, with Dark Beast mistakenly revealing that Prelate Scott Summers is also dead. Dark Beast soon finds the life seed but before he could hand it over to the X-Force members, Nightcrawler teleports in and swipes the seed away, figuring that Dark Beast was up to some evil plot. After a brief quarrel which ended with the life seed destroyed by Sunfire and Psylocke recognizing Sabretooth from her time on the Exiles, Dark Beast sneaks over to the portal back to the main Marvel Universe, Earth-616, and walks in, leaving X-Force stranded in the Age of Apocalypse world. He then released the now fully evil Dark Angel from his prison and helped him form an army to devastate Earth.
