also received a new ongoing series when the character found himself in (from his perspective) an alternate past. During this period, the mutants dealt with the threat of the Terrigen cloud that circulated the world and appeared to be toxic to them, placing the X-Men at odds with the Inhumans. The X-Men also dealt with Apocalypse resurfacing, and the truth of what happened between Cyclops and the Inhumans that led to his death. Storm's team resided in Limbo and worked to bring mutants to safety away from the Terrigen. Magneto's team took on a more militant approach. Beast worked alongside the Inhumans to attempt to find a way to alter the state of the Terrigen, but later discovered that it couldn't be altered and would have rendered Earth toxic for mutants. This revelation caused the X-Men to declare war against the Inhumans, but this conflict ended when the Inhumans learned what was happening, with Medusa sacrificing the Terrigen cloud to save the mutants.

The X-Men were also involved in the "Civil War II" and "Monsters Unleashed" storylines.
