Five years into Superman's Regime, the Insurgency discovers a parallel universe where Joker's plan failed, and teleports that world's Wonder Woman, Aquaman, Green Arrow, and Green Lantern into their universe, as well as Batman and the Joker by accident. As Green Lantern encounters and battles Sinestro and his own Yellow Lantern counterpart, Aquaman also fights his evil counterpart, discovering that Atlantis joined Superman's Regime. The prime universe heroes eventually meet the Insurgency Batman and Lex Luthor, an Insurgent mole inside the Regime, in Gotham City, who reveal a nanotech pill derived from Kryptonian DNA created by them, which can empower regular humans, giving them a fighting chance against Superman.
