Following his two failed invasions of Earth, Darkseid has destroyed countless worlds, prompting the Justice League and the Teen Titans to launch a counter-attack on Apokolips. Unbeknownst to the heroes, Darkseid is spying on them through Cyborg's Apokolyptian technology and is aware of their plan. The League travel to Apokolips while the Titans remain on Earth. Upon their arrival, the League is massacred by Darkseid's Paradooms, genetic hybrids of Parademons and the monster Doomsday. Several heroes are killed and the rest are captured. John Constantine flees from the attackers, leaving his lover Zatanna to be killed.
