Witness the genesis and evolution of mutantkind with Uncanny X-Men (1963), the original and longest-running series in Marvel's X-Men franchise. Created by Stan Lee and Jack Kirby, the series initially introduced Professor Charles Xavier and his first class of gifted youngsters – Cyclops, Marvel Girl, Beast, Angel, and Iceman – a team of mutants learning to control their incredible powers while fighting for a world that fears and hates them. Though it faced an early cancellation, the title was famously revitalized in 1975 with Giant-Size X-Men #1, ushering in a new, diverse international team and launching the legendary 16-year writing tenure of Chris Claremont, who transformed the book into a global phenomenon. From iconic storylines like "The Dark Phoenix Saga" and "Days of Future Past" to the introduction of countless beloved characters such as Wolverine, Storm, Nightcrawler, Colossus, Kitty Pryde, and Rogue, Uncanny X-Men has been the bedrock of the mutant saga. It has explored themes of prejudice, identity, and social justice, all while delivering thrilling superhero action and complex character drama. Across numerous volumes and creative teams, this series has consistently been at the forefront of mutant adventures, shaping the destiny of the X-Men and the entire Marvel Universe.
