When the Terrigen became toxic for mutants, Iceman was one of the recruits in Storm's new team dedicated to protecting mutants from the Terrigen by leading them to X-haven. Iceman mostly works alongside Nightcrawler, helping him search for Colossus after he is transformed into one of Apocalypse's new horsemen. Iceman and Nightcrawler manage to track Colossus to Egypt, where he ambushes them and almost kills them until another squad of X-Men comes in to help. After that Iceman joins the X-Men when they declare war against the Inhumans after discovering that in a matter of weeks the Terrigen will render earth as completely uninhabitable for mutants.
