Superman: Action Comics: Superstars #[1]

In the wake of a strange encounter on Sorcerers' World, Bizarro returns to Earth—now wielding magical powers that make him a more dangerous foe than ever. As Superman faces this twisted echo of himself, old allies like Lois Lane and Jimmy Olsen must grapple with the chaos, while mysterious sorcerers like Sorcerer Ponderous and Sorceress Graves watch from the shadows.

In a Metropolis overrun by Bizarros, Superman races to save his city and himself as the very presence of Bizarro begins to warp his mind. With Lois Lane, Batman, and an unlikely alliance of Blue Devil and John Constantine at his side, he must hold on to his humanity while the world around him descends into chaotic mimicry.

In a world where every person has become a twisted Bizarro version of themselves, Superman must turn to the one mind he can’t trust—The Joker—for help. With Lois Lane, Jimmy Olsen, and Bibbo caught in the madness, Clark Kent faces his most bizarre challenge yet: saving everyone, including Bizarro, from a reality gone terribly wrong.

In "Challenge from the Stars Part One: They Have Waited an Eternity," Superman is approached by two alien emissaries—Xalt of the S'tahl and Grunhar of the Gorathians—whose people have endured centuries of enslavement. With Earth's fate hanging in the balance, they task Clark Kent with facing their oppressors' champion in a trial that could determine the liberation of an entire species.

Lois Lane grapples with self-doubt as she steps into the role of editor at the Daily Planet, testing her resolve when her vision for covering Superman clashes with Clark Kent’s. With Jimmy Olsen watching closely and Mariposa Lujan keeping her distance, the tension between Lois and Clark deepens—just as a mysterious threat stirs in the city.

In "Challenge from the Stars: Falling Like Rain from a Metallic Storm," Superman faces a relentless test as Grunhar of the Gorathians unleashes a devastating aerial assault on Metropolis, forcing the Man of Steel to defend the city from a crashing aircraft carrier. With the stakes rising, he must now confront the second trial—saving the bottle city of Kandor from annihilation, as the Gorathian warlord’s schemes threaten to erase one of Earth’s most treasured relics.
