Superman / Batman #1

In a storm of conflicting loyalties and escalating threats, Superman and Batman are thrust together when Metallo wreaks havoc at S.T.A.R. Labs, forcing the Man of Steel to confront the villain in Gotham—only to be betrayed and buried alive by him. As the city braces for a new danger, a Kryptonite asteroid looms over Earth, and President Lex Luthor prepares to exploit the chaos, setting the stage for a collision of wills, ideologies, and destinies.

In the wake of a brutal fight, a wounded Superman and Batman struggle to reach the Bat Cave, only to find an unwelcome visitor waiting in the shadows. As the dust settles, President Lex Luthor delivers a chilling statement that sends shockwaves through the crumbling alliance.

While searching for fragments of the Kryptonite meteor that hit the Earth, Batman discovers a Kryptonian spaceship at the bottom of a harbor. Inside, he finds a young woman—Kara Zor-El—alone and adrift, her connection to Krypton the only thing she remembers. Superman arrives to help, but the truth of her origins may be more complicated than either hero expected.

In "The Supergirl from Krypton, Part Three: Warrior," Supergirl faces a desperate fight as Darkseid's forces unleash imperfect Doomsday clones to overwhelm Superman, Batman, and Wonder Woman—while a second team moves to capture her. With Paradise Island under siege and allies stretched thin, Kara Zor-El must confront her own limits as the battle tests her strength, resolve, and what it means to be a warrior from Krypton.
