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 first outer space saga with the Starjammers, and rare early X-Men adventures! With comic book titans Chris Claremont, Dave Cockrum and John Byrne at the helm, the X-Men's rise to the peak of popularity starts here! Collecting GIANT-SIZE X-MEN #1; X-MEN (1963) #94-110; MARVEL TEAM-UP (1972) #53, #69-70 and ANNUAL #1; IRON FIST (1975) #14-15; and material from F.O.O.M. #10.
