Regime. Meanwhile, Aquaman defeats his counterpart in Atlantis, who was negotiating an alliance between Atlantis and the Regime. He then encounters Ares, who is weak from the virtual lack of conflict and has allied with the Insurgency out of spite for the Regime. After regrouping, the prime heroes meet Insurgency Batman and Lex Luthor (who in this universe is Superman's closest friend and an Insurgency mole) and receive nanotech pills derived from Kryptonian DNA, which increase their strength to Superman's level. Batman and Luthor explain to the heroes that they teleported them into their universe to help access a kryptonite weapon, which requires a DNA sample of all core Justice League members; however, the prime Batman and Joker were teleported by accident. Elsewhere, Batman is mistaken for his Insurgency counterpart and captured by the Regime, while the Joker meets this universe's Harley Quinn, who is allied with the Insurgency and founded the "Joker Clan" in his memory. After helping the Joker Clan fight off a Regime attack at Arkham Asylum, the Insurgents infiltrate the Batcave and retrieve the kryptonite weapon.

When Shazam protests and invokes Lois' memory, Superman murders him, causing Flash to defect to the Insurgency. During a Regime attack on the Insurgency's hideout, Wonder Woman is teleported by Ares to Themyscira, where she defeats her Regime counterpart and convinces the Amazons to defect to the Insurgency. Meanwhile, prime Batman convinces
