In an alternate universe, Joker tricks Superman into killing his pregnant wife Lois Lane, which detonates a nuclear weapon that destroys Metropolis and kills millions. Consumed by grief and rage, Superman murders Joker in retribution, quickly losing his moral compass. Over the following years, Superman becomes a ruthless dictator who establishes a unified world government named the One Earth Regime that eliminates crime through a worldwide totalitarian regime, which he leads as its High Councillor alongside several Justice League members and super villains who serve as his lieutenants. Now viewing Superman as Earth’s greatest threat, Batman establishes an Insurgency of heroes against his tyrannical regime. A war breaks out between the two factions, ultimately leaving the Justice League disbanded.
