Justice League Unlimited

Supergirl, Green Lantern and Green Arrow are kidnapped and taken to the 31st Century by Brainiac 5 and Bouncing Boy of the Legion of Super-Heroes, where Supergirl is destined to embark on her very last mission – a battle against the Fatal Five and the Legion itself.

The Hawkman story concludes here when Shadow Thief captures Green Lantern, Shayera and Hawkman, then forces them to watch a vision of their past selves developing an ancient society of Egypt with Thanagarian technology. It turns out Shadow Thief is a villain from Carter Hall's mind that was released when he touched the Absorbacron in "Shadow of the Hawk." Hawkman defeats Shadow Thief and leaves. John Stewart, not wanting to have destiny play out his life, does not get back with Shayera, even though the two say they love each other. GL goes back to Vixen, but not before he tells Shayera about Rex Stewart (Warhawk), their alleged future son. In the final scene of the episode, Shayera asks Batman about this future son, but the credits roll before he can answer.

Luthor and the Secret Society refit their headquarters and fly into deep space in a last-ditch attempt to reanimate Brainiac. En route, Tala frees Grodd, who leads a mutiny of other disaffected villains against Luthor and his supporters. Luthor uses his intellect and resourcefulness to counter his various adversaries' powers; Grodd's mind-control ability is used against him, forcing him to step into an airlock, from which he is released into the void. Luthor uses Tala's magic in an attempt to reconstitute Brainiac, but instead resurrects Darkseid (with Brainiac enhancements), who makes clear his plans to lay waste to Earth before destroying the Secret Society's headquarters. Darkseid returns to Apokolips just in time to stop a war between the two factions of his Elite fighting for power, and reveals to them his plans of massive invasion. Luthor and the surviving Secret Society members turn to the Justice League for help.

The Justice League reluctantly teams up with the remnants of the Secret Society to repel Darkseid's full-scale invasion of Earth. As the League and Secret Society members battle the Apokolips fleet across the planet, Superman, Batman, and Lex Luthor take on Darkseid atop the Daily Planet building.
