After the death of Lois Lane and her unborn son caused by Superman (who was drugged by the Joker with Scarecrow's Fear Toxin laced with Kryptonite) as well as the destruction of Metropolis, Superman decided the world wasn't safe enough from criminals and villainy, so he created a new government in the form of a dictatorship after murdering the Joker in a moment of madness at the time when Batman was interrogating him on where he got the nuke that destroyed Metropolis. Upon starting the One Earth Regime, he made himself the High Councillor. Several heroes such as Wonder Woman, Cyborg, and even Robin joined the cause and other villains like Sinestro, Solomon Grundy, Black Adam, and Bane joined too where they were paid

Batman agrees and he and Catwoman recruit Black Canary, Black Lightning, Captain Atom, Huntress, Batwoman, Green Arrow, and Aquaman to their cause with the Martian Manhunter working as Batman's secret ally.
