NEED TO KNOW
Superman’s cousin is flying into the spotlight.
Based on the Tom King and Bilquis Evely comic series of the same name, Supergirl: Woman of Tomorrow follows Kara Zor-El, aka Supergirl (Milly Alcock), who teams up with a young alien girl (Eve Ridley) seeking revenge for her father’s murder. Together, they embark on a dangerous cosmic journey across alien worlds, facing powerful enemies and moral dilemmas.
In June 2025, the co-CEO of DC Studios, James Gunn, teased that even though Superman and Supergirl are both from Krypton, they had very different childhoods.
“[Superman] had parents who loved him in an easy-going upbringing, and it makes him the least dysfunctional of superheroes in so many ways,” he told ComicBook.com. “And Supergirl, especially the DCU Supergirl, she’s kind of a mess. I mean, she’s had real issues growing up.”
That became clear during Supergirl’s brief cameo in Superman, which premiered on July 11. Alcock’s character appeared at the Fortress of Solitude — clearly hungover — and retrieved her dog, Krypto, who had been under Superman’s care while she partied across the galaxy.
Here’s everything to know about the highly anticipated Supergirl.

The Supergirl storyline draws heavily from King and Evely’s entry in Supergirl’s seven-issue comic series.
Kara Zor‑El, aka Supergirl, hardened by trauma and tragedy, celebrates her 21st birthday far from Earth aboard a spaceship with Krypto, her loyal super‑dog. When a young alien girl named Ruthye Marye Knoll — whose father was brutally murdered — pleads for Supergirl’s help in tracking down the killer, the two embark on a quest across distant worlds.
Stripped of her powers under a red sun, Supergirl must rely on her grit, compassion and wits to guide Ruthye on a path of vengeance and justice, ultimately confronting the nature of violence and power.
