Complete story — includes the ending
It is revealed that General Zod was sent to the Phantom Zone by the House of El before Krypton's destruction. He is released in the 31st century by the United Planets, but gets re-imprisoned by the Legion after planning an invasion. Lor-Zod, his son, travelled back in time to kill Superboy, who inspired the creation of the Legion of Super-Heroes. Lor now plots to steal a Phantom Zone projector to free his parents and their followers. En route to New Genesis, Green Lanterns Tomar-Re and Kilowog reunite with Blue Lantern Razer, after four years of his quest. On the planet, Razer trades his new ring for his old red one to Metron, who goads him into unleashing its power. After injuring Female Forager by accident, Razer realizes his mistake and decides to use both his rings at once, before leaving to find his displaced love, Aya. Meanwhile, Bart agrees to assist the Legion and installs a cosmic treadmill on M'gann's retired bio-ship. In a mid-credits scene, the team celebrates Jay's 102nd birthday.
