In "Worlds Collide!", Batman and Robin from a world without Superman cross paths with Superman and Lois from a reality where Batman never existed, as their lives intertwine across fractured dimensions.

In "Worlds Apart!", alternate versions of Batman, Robin, Superman, Lois Lane, and Jimmy Olsen race to uncover the truth behind the fractured realities linking them to shadowy doppelgängers of Lex Luthor, Martha Wayne, and Bruce Wayne—while in the real world, Superman and Batman face an eerie entrapment at the hands of the enigmatic Auteur.Io.

In "Across Worlds!", the real-world Superman and Batman are ensnared by Auteur.Io inside a Phantom Zone crystal, forcing their alternate reality counterparts—Superman, Batman, and Robin—to chase him across fractured dimensions in a desperate bid to stop him.

In "Worlds Burn!", Superman, Batman, Robin, Alanna, and El Diablo race to protect Superman's World of Tomorrow as Auteur.Io unleashes Etrigan and a horde of demons in a devastating assault.

The fate of countless realities hangs in the balance as heroes from across the multiverse converge to protect the very fabric of existence.

In "Superman in The World of the Knight!", Superman from The World of Tomorrow swaps places with Batman and Robin to confront Lex Luthor, who has seized control of Metropolis and renamed it Lexopolis.

In *Batman and Robin in The World of Tomorrow*, Batman and Robin from The World of the Knight swap places with Superman to confront a chilling threat: a fractured Bruce Wayne who has become Bizarro Two-Face in the dystopian future of The World of Tomorrow.
