Superman / Batman: Supergirl #[nn]

In a Gotham shrouded in mystery, Batman uncovers a Kryptonian rocket buried beneath a massive meteor, its inscriptions hinting at a long-lost survivor. A young blonde girl with untamed powers stumbles through the city, her presence triggering chaos until Superman and Batman work together to bring her down—and discover she’s not just another alien, but his long-lost cousin, Kara Zor-El.

In "null," Kara Zor-El struggles to find her place on Earth, her bond with Superman tested by Batman’s wary skepticism and Krypto’s uncertain loyalty. When an unexpected assault by Artemis, Harbinger, and Wonder Woman leaves her questioning who she can trust, the fragile alliance between the heroes is pushed to the edge.

In "null," Superman, Batman, and Wonder Woman grapple with the best way to guide Kara Zor-El as she trains on Paradise Island, seeking to ground her in the strength of her new allies. When Doomsday constructs descend upon the island, the Amazon warriors and their allies fight to defend it—only for one life to be lost and Kara to vanish without a trace.

In the heart of Apokolips, Superman, Batman, and Wonder Woman team with Barda to rescue Kara Zor-El from Darkseid’s grasp. As the mission fractures into chaos, Wonder Woman and Barda are captured, and Batman vanishes—leaving Superman to face a shocking reunion with Kara, who now stands beside Darkseid as if she has chosen her new allegiance.

In a high-stakes clash across Earth and Apokolips, Superman faces off against his cousin Kara Zor-El as Wonder Woman and Barda fight the Female Furies, led by Granny Goodness and her enforcers Gillotina, Stompa, Bernadeth, Lashina, and Mad Harriet. With Batman making a bold move against Darkseid in a desperate bid to free Kara, the battle rages—until a devastating twist shatters the moment. As Kara embraces a new identity in a costume echoing Superman’s, the cost of victory begins to unfold in heart-wrenching fashion.

When Darkseid strikes and Supergirl falls, Superman’s fury ignites a battle that shakes the cosmos. As Earth’s mightiest heroes rally—Wonder Woman, Batman, and countless others—truths unravel in the wake of destruction. In the aftermath, a new guardian rises, proving that even in darkness, hope can take flight.
