Batman/Superman

The dimension-shattering Archive of Worlds saga ends here—and reverberations from this titanic tale last long after the dust settles! As the Dark Knight and the Man of Steel work to halt the villainous Auteur.io’s plan here on Earth-0, the Batman and Superman of their respective archive worlds must team up with Alanna of Rann and El Diablo himself to save what’s left of their homes. Etrigan and his demon hordes rain Armageddon down on their pocket universes—and the fate of the World of Tomorrow and the World of the Knight hang in the balance!
