The Exiles battled a Hyperion-led Weapon X, almost destroying the entire world. Nine years after Hyperion's defeat, Earth-4400 was on the road to recovery. However, Hyperion's actions wiped out many of Earth-4400's heroes, allowing the villains to run amok in America. Eventually, the United States passed a law to make superpowers illegal, although this did nothing to cull the amount of super villains. In the long run, many cities became overrun with mutants or genetically engineered miscreants fighting for control in turf wars.
