The history of the X-Men of Earth-1210 matches that of their Earth-10005 counterpart up until saving the mutants from Three Mile Island. After finding Jean Grey, Xavier began controlling her with telepathic blocks because he believed her class 5 powers were too much for her to handle. Some time after finding Jean, the X-Men recruited 16 year old Robert Drake (Iceman), who was a class 5 mutant according to Xavier, together with teenagers Havok (Cyclops' brother) and Angel.
