X-Men(1459)

Hated and feared for powers given to them by an X-gene in their chromosomes, the X-Men were assembled by Charles Xavier, with the dream that one day Mutants and Humans could live together in peace. X-Men members come from all over the world in all shapes and sizes.

History
Prior to the formation of the X-Men, Professor Charles Xavier and Erik Lensherr were contacted by agents of the CIA to help investigate the Hellfire Club, a clandestine organization of mutants with suspected criminal operations. The association with the CIA soon brought Xavier into contact with other mutants, Darwin, Mimic and Banshee.

Xavier's mutant group then came into conflict with the Hellfire Club, which led to the murder of Mimic at the hand of the Hellfire Club's leader. Xavier resolved to stop the Hellfire Club and began training his young group in preparation for conflicts to come. During subsequent confrontations with the Hellfire Club, Erik and Charles' views regarding the path of the emerging mutant race diverged, resulting in the Hellfire club leader to escape with his life.
