Age of Apocalypse Fire & Ice

Bobby was among the first mutants located by Magneto who founded and trained the X-Men. Magneto pushed the boy much harder than Xavier would have, trying to make the youngster drop his humorous attitude and tap into his full potential. During his first mission with the X-Men, Iceman helped prevent the Horsemen of Apocalypse from taking over Cape Citadel and launching its cache of nuclear weapons. In later years, Bobby tried to encourage Gambit to propose to his teammate Rogue. This attempt came too late, as Rogue had already come to embrace a romance with Magneto, alienating Gambit from the team.

During the beginning of Apocalypse's rise, Magneto approached Japan's greatest heroes, Sunfire and the Silver Samurai, and asked them to work with him and the X-Men to stop Apocalypse. Sunfire accepted the invitation despite his country's isolationist policies and left his cousin behind. During Apocalypse’s blitzkrieg attack on Asia and Europe. Sunfire rushed home to Japan. Magneto had asked Sunfire to wait until after the X-Men helped in Moscow but Shiro could not. When Sunfire arrived in Japan he found his country in flames and Silver Samurai leading refugees away from Apocalypse.
