Superman and the Legion of Super-Heroes #[nn]

In the 31st century, Cosmic Boy, Lightning Lad, and Saturn Girl tunnel into the Batcave seeking proof of Krypton’s existence, only to be confronted by the newly formed Justice League—Earth-Man, Spider-Girl, Tusker, Golden Boy, Storm Boy, and Radiation Roy—former Legion applicants turned adversaries. After a fierce clash, Superman steps in, learning the shocking truth behind the League’s actions and the fate of his fellow Legionnaires, leading him to track down Brainiac 5 at an alien holding camp.

In "Chapter 3: Lightning and Shadows," Superman and the Legion of Super-Heroes race to rescue captured aliens, only to find that Brainiac 5 has vanished back to Colu. With Earth-Man and the Justice League closing in, Dawnstar leads the team through a desperate escape, but their journey takes a dangerous turn when they’re captured by Colu’s advanced defenses.

In the 31st century, Superman and several Legionnaires are held captive by Brainiac 5, who reveals a desperate plan to stop an impending invasion of Earth by the United Planets. With time running out and a mole within the Justice League exposed as Chameleon Girl, the truth begins to unravel — but not before Brainiac 5 must choose between staying to help or fleeing with the captured heroes.

In "Chapter 5 - Revenge of the Rejects," Superman and the Legion of Super-Heroes face a twisted test of loyalty when they return to Earth and enlist the Legion of Substitute-Heroes to create a distraction. As the team infiltrates Justice League headquarters, they uncover the truth behind the Legionnaires' disappearance—only to confront Earth-Man, a rejected hero consumed by resentment, who now wields stolen powers and a grudge against Superman. The battle escalates beyond the planet’s surface, forcing a desperate fight in the cold vastness of orbit.

In "Chapter 6: Sun Rise," Superman finds himself stranded in a fractured future, his powers gone and his flight ring destroyed, as Earth-Man manipulates the Legion of Super-Heroes' technology to turn the tide. With the sun on the brink of shifting back to yellow, Chameleon Girl must awaken Sun Boy to restore balance, while the rest of the Legion races to stop Earth-Man's escalating assault. As the battle reaches its peak, Superman and his time-traveling allies face a final reckoning—both against a rogue enemy and the weight of their shared past.
