James Gunn has revealed that the upcoming James Gunn Supergirl movie Krypto will feature the beloved canine in a life-threatening situation, raising the stakes for Kara Zor-el’s big-screen journey. With Milly Alcock starring as Supergirl, this 2026 film builds on Kara’s recent appearance and explores her new role as a lead hero in the developing DC Universe.
Supergirl’s Space Saga Brings High Stakes for Krypto
Following Supergirl’s introduction at the conclusion of Superman, DC Studios is bringing the character center stage in a story inspired by Tom King’s Supergirl: Woman of Tomorrow miniseries. The narrative follows Kara Zor-el as she faces a powerful foe and embarks on a quest for justice after her most trusted companion suffers a brutal attack. This emotional arc is set to be realized on screen, as James Gunn provided fresh details about Kara’s next adventure.
During a special appearance at Supergirl’s CCXP Booth, DC Studios co-CEO James Gunn highlighted the complex emotional dilemma facing the new DC Universe heroine. Gunn described the film as featuring a protagonist trying desperately to save her beloved dog from mortal peril, confirming the critical role that Krypto will play in the storyline. The threat facing Krypto becomes the catalyst for the action, propelling Kara on a dangerous journey through uncharted space and confronting adversity at every turn.
“‘Supergirl’ is the next big story in the DCU and in the Superman Saga. It is a space epic in which our sort of troubled heroine is on the road to trying to save the life of her dog, Krypto, from ‘Superman.'”
— James Gunn, DC Studios co-CEO
Krypto’s return in the film has already been confirmed, with the character expected to be deeply integrated into the movie’s plot. This is a natural progression, as Krypto and Kara were last seen together in the closing scenes of Superman, implying their bond would be central to Kara’s future story.
The Source Material’s Influence on the Film
Fans familiar with Woman of Tomorrow know that the original series opens with a shocking event—Krypto is struck by a poisoned arrow from the villain Krem of the Yellow Hills, placing the loyal companion at death’s door. This act not only leads Kara on a path of retribution but also sets the stage for an emotional journey, as she searches the cosmos for a way to save her friend while seeking justice against her enemy.
This storyline is set to be translated to the screen with high fidelity to the source material, and Krypto’s ordeal is likely to define the way Kara evolves as both a protector and an individual. The companion book The Art of Superman further elaborates on Krypto’s importance, as DC Studios co-leader Peter Safran points to the character as a crucial link between the films in the ongoing DCU saga.
“And then, of course, the greatest connective tissue of them all is Krypto. Krypto has a major role in Superman and is, in many ways, the inciting incident of Supergirl. So that connection really helps an audience move from one film to the next.”
— Peter Safran, DC Studios co-CEO
This alignment ensures narrative continuity between Superman and Supergirl, as the transition is paved by Krypto’s heightened involvement, deepening the connection for viewers and expanding the emotional impact across the DC cinematic storyline.
Krypto’s Role in Shaping Kara Zor-el’s Transformation
Supergirl’s commitment to Krypto adds complexity to her character, bringing emotional vulnerability to the fore. The close relationship established between the Kryptonian heroine and her loyal dog means that any threat to Krypto could evoke intense reactions from Kara. The plot’s focus on rescue and revenge introduces an opportunity to portray her as not only a fierce warrior fighting formidable enemies like Krem, but also as someone grappling with profound loss and responsibility.
The revenge quest at the heart of the movie signifies that viewers will witness a driven and impassioned Kara Zor-el, one whose anger propels her into action. However, the narrative also promises to explore the softer aspects of her character, as the possible loss of a companion brings her face to face with memories of already devastating hardships, such as the destruction of her home planet. This challenge will force Kara to accept her own emotional responses and internal strengths, highlighting her resilience and determination to do what is necessary for those she cares about.
What Audiences Can Expect from the 2026 Release
The story is expected to echo the adventurous and heartfelt tones reminiscent of Guardians of the Galaxy, as Supergirl’s arc evolves from a troubled protector to a fully-realized superhero. Starring Milly Alcock in the title role and featuring a supporting cast that includes Jason Momoa, Matthias Schoenaerts, Eve Ridley, and David Krumholtz, the film promises a dynamic blend of high-stakes drama and cosmic adventure. Moviegoers will have the chance to witness Supergirl’s transformation on the big screen when the film arrives in theaters on June 26, 2026.
By putting Krypto at the heart of the emotional stakes, the James Gunn Supergirl movie Krypto storyline attaches a deeply personal dimension to Kara Zor-el’s journey. Through trauma and adversity, the film appears poised to redefine the classic superhero narrative, ensuring that the DC Universe’s next chapter will be both thrilling and emotionally resonant for fans old and new.
