With the original X-Men captured, Professor X recruits an all-new, all-different team to take on the mantle of the Uncanny X-Men including Wolverine, Storm, Colossus, Nightcrawler, Banshee, Sunfire, and Thunderbird, this new international cast redefined super-hero teams forever. The transition from old team to new won’t come easy, though: Wolverine and Cyclops clash. X-Man battles X-Man. Death and rebirth visit the team and an old nemesis returns. Plus: the first hints of Alpha Flight and the Weapon X program, the team’s first outer-space saga with the Starjammers, and rare early X-Men adventures.
