While Batman and Superman are fighting the Atomic Skull who was stealing a briefcase with radioactive materials in it from Wayne Tech, the Maximums appear, seeking revenge. The Soldier fires a bullet at the Skull, and it passes through Superman's hand and causing the Skull to violently release a large amount of radiation that Superman acts to contain. Although Robot observes Superman's heroic act, Viking will have none of it. Soldier and Monster attempt to subdue Batman when Batzarro intervened, blinding everyone with his "smoke" bombs. Eventually, the Maximums were able to capture Superman and Batman, and returned to their world via Boom Tube.
