When a new villain wields the Dimensionator, the X-Legion is fractured, with Lucifer Beauregard/Red Hour and others lost across the multiverse. Hope rests on the shoulders of their children: Fallon/Pyrohydra, Sierra/Mindwave, and Percy/Trackstar, who join forces with Kenji/Metal Boy, Kylan/Icestorm, and Alicia/Terraquake. Together, they must traverse dangerous dimensions, honing their abilities to not only rescue their parents and the scattered X-Legion, but also to confront the mysterious villain and prevent the Dimensionator from causing irreversible damage to reality itself. Their journey is a race against time to restore balance and save the multiverse from utter destruction.
