Professor X is later revealed to be alive and the X-Men return to the Xavier Institute, which is also when Iceman rejoins the X-Men line up. Jean Grey soon discovers that fellow X-Man, Colossus, is using a drug called Banshee to enhance his mutant abilities. The X-Men are highly against this, but Colossus manages to convince Rogue, Dazzler, Angel, Nightcrawler, and Cyclops to join him on his own X-Men team. Iceman remains on Professor X's drug-free X-Men and fights the Banshee enhanced X-Men. Xavier's X-Men win and the two teams combine again with nobody using drugs.
