Charles Xavier has a dream. Mutant mentor to the heroic X-Men, Professor X envisions a world in which humans and mutants can live together in peace, harmony and understanding. Magneto is a mutant with a darker dream, one of total domination over all humankind. The X-Men have faced Magneto, and mutant peace has triumphed over mutant warfare. Now, the teenage adventurers face a far more difficult obstacle: the hatred of the very humans they wish to protect. This battle will be one of the mind, not muscle.

To win humanity's trust, the X-Men embark on their first-ever world-spanning field trip. Yet they soon learn that Human hostility is not limited to American soil. Nor have the X-Men left their personal problems behind. Colossus escaped the Russian Mafia when he joined the team, but now finds his former employers wont let him go so easily. Meanwhile, the beleaguered X-Men fight for their lives against their most formidable threat yet when Professor X's darkest secret comes back to haunt him--with a vengeance!

Plus: There are mutants who live outside the walls of the Xavier Mansion. Introducing Gambit, a street hustler who must use his genetic gifts to protect a girl in great danger!
