Batman tells The Flash that he is too important to fight. He is the key to save the world.
 * Since the destruction of Oa, Hal Jordan has been severely weakened and his lantern is almost depleted.
 * The team regroups in a secret lair under Wayne Manor. Cyborg, who is more machine than ever now, is working on creating the Cosmic Treadmill. The plan is jump The Flash back in time. This can only be done once a year, when the Earth is in the same exact location so that The Flash does not run into something. The treadmill can only be powered by a Motherbox, which were last seen in The Justice League. Once the Motherbox is powered up, Injustice Superman will notice and will come to attack.
 * Deadshot tells the story of when the parademons took his daughter. Almost the entire world is under the spell of the Anti-Life Equation.

 * Hawkman throws the Motherbox in the pseudo-Batmobile and Batman drives off. Superman arrives, but Deadshot shoots a Kryptonite bullet at him (the last piece of Kryptonite found on Earth). Injustice Superman dodges it and kills Deadshot. Mera attempts to drain water out of Injustice Superman, but is killed instead. Hawkman slows Injustice Superman down, but is also defeated. Batman and the Batmobile enter the Batcave, followed by Injustice Superman. Hal Jordan uses the remaining lantern force he has to shield Injustice Superman from entering, however Injustice Superman eventually gets through and kills Green Lantern.

He explains that they need allies across the galaxy to help stop him. Orion returns to New Genesis and uses Metron to send out signals across the galaxy about the fight.
