Thanks to the sacrifice of Strange Visitor and General Rock, Earth's forces crack Imperiex's armor, releasing his energy. However, Brainiac-13 appears with Warworld and absorbs the energy, vowing to use it to rule everything. In a desperate gambit, Superman dives into the Sun, gaining a massive power boost. Realizing that Warworld cannot be destroyed without releasing Imperiex and triggering another Big Bang, Superman and Martian Manhunter transport Imperiex and Brainiac back in time to the Big Bang, destroying them both.
