Vandal Savage, a Machiavellian immortal, meticulously steals the remains of the deceased hero Metallo and orchestrates a daring heist on the Batcave to acquire Batman’s classified contingency plans. These secret protocols detail the exact methods needed to neutralize every member of the Justice League should they ever go rogue. Savage envisions using these bespoke weapons of
mass destruction not to kill the heroes outright, but to utterly incapacitate them while he launches a catastrophic solar flare designed to incinerate half the human population, leaving the survivors begging him for leadership.Savage recruits a lethal roster of supervillains, including Mirror Master, Cheetah, Star Sapphire, Ma'alefa'ak, Bane, and Metallo, tasking each with executing a specific, psychological ambush tailored to their assigned Justice League member. The master plan unfolds with brutal efficiency. Superman is tricked into shooting a Kryptonite bullet coated in synthetic red solar radiation, slowly bleeding his invulnerable vitality. Batman is trapped in a psychologically agonizing simulation reliving his parents' murders, indefinitely stalled by his own grief. Wonder Woman is poisoned by Cheetah with a nanite toxin that makes her perceive everyone as Cheetah, causing her to exhaust herself in a relentless, hallucinated frenzy until her heart gives out. The Martian Manhunter is exposed to a volatile magnesium-based compound that causes his skin to spontaneously combust whenever it contacts air, causing excruciating agony. Green Lantern experiences a
crisis of faith engineered by Star Sapphire, rendering his ring useless as he watches a simulated hostage crisis. Meanwhile, the Flash is fitted with a specialized vibrating bomb strapped to his wrist that will detonate if he slows down, forcing him to run constantly or cause a city-destroying explosion.Though nearly destroyed, the League manages to survive the coordinated onslaught through sheer resilience and unexpected allies. Batman overcomes his psychological trauma, and Cyborg joins the team, providing the technological prowess needed to track Savage’s signal to his remote fortress. The League converges on the stronghold just as Savage initiates his apocalyptic solar flare device. A ferocious battle erupts against Savage and his Legion of Doom. Batman and Superman work together to shut down the weapon moments before global devastation occurs. Savage is defeated and taken into custody, but the victory is bittersweet. In the aftermath, the Justice League convenes to discuss the alarming breach of trust. Superman, Wonder Woman, and the others confront Batman for weaponizing their deepest vulnerabilities against them. Realizing the immense danger his paranoia poses, Batman resigns from the League, leaving his former comrades to ponder the fragile nature of their alliance and the dangerous ethical boundaries of heroism.
