DC Studios has clarified that Supergirl is not simply Superman’s sidekick, but a hero who stands on her own. This misconception originated in early DC Comics stories from the Silver Age, where Superman helped Supergirl (Kara Zor-El) learn to control her powers and adapt to life on Earth. The TV show Arrowverse also initially portrayed this mentor-mentee dynamic, but ultimately showed Kara becoming a hero in her own right. Now, before Supergirl’s first major movie appearance in the new DC Universe this year, DC Studios has officially corrected this misunderstanding about her character.
DC Studios shared a new poster for the upcoming Supergirl movie, featuring Milly Alcock as Kara Zor-El alongside her canine companion, Krypto (@TaurooAldebaran first reported the news).
The poster boldly states, “She’s not anyone’s sidekick,” directly addressing and dismissing fan theories that Supergirl is simply Superman’s helper.

Initially, the character seemed like a supporting player, but later stories developed her into a fully independent hero. Supergirl moved beyond being a sidekick, forging her own path with new storylines and enemies.
The Arrowverse eventually fully supported Supergirl as her own hero, especially after her show (starring Melissa Benoist as Kara Danvers) proved she could stand on her own. During the five-episode Crisis on Infinite Earths event, the CW series even showed Supergirl being more powerful than Superman at a crucial moment in the fight against the Anti-Monitor.
DC Studios plans to redefine Supergirl, specifically Kara, by highlighting her independent space adventures in the 2026 film Supergirl. Starring Milly Alcock, the movie will focus on her unique journey and establish her identity separate from Superman.
Supergirl is set to premiere in theaters on June 26, 2026.
One Exciting Dynamic In ‘Supergirl’ Erases Her Sidekick Status

With the introduction of Ruthye, a dedicated ally for Kara Zor-el, Supergirl can really establish Kara as a hero who stands on her own, not as someone’s helper.
Tom King’s Supergirl: Woman of Tomorrow tells the story of Ruthye, who pays Supergirl to track down Krem of the Yellow Hills and avenge her father’s death. What begins as a simple job transforms into a deep, sisterly connection between them, allowing Kara to grow into a more self-reliant and leading hero.
In Supergirl, Kara takes on the role of a mentor and protector for Ruthye. The preview suggests that Ruthye sees Kara as a heroic figure who can keep her safe and fight for what’s right, similar to how people on Earth look up to Superman as a symbol of hope.
Honestly, I’m really excited about the 2026 Supergirl movie. It feels like it’s finally letting Kara step out of Superman’s shadow and truly become her own hero. It’s cool that her relationship with Ruthye will be a big part of that, helping her see she doesn’t need to be perfect like Superman to be a leader. Instead, she can inspire people through her strength and how she bounces back from challenges, and even be a mentor herself. It’s a much more relatable and interesting take on the character, in my opinion.
