When you think of “Superdog,” the image that likely comes to mind is a noble, cape-clad canine companion soaring beside Superman—well-behaved, loyal, and bursting with golden retriever energy. But in James Gunn’s upcoming Superman (2025), Krypto is anything but predictable. This version isn’t just a sidekick; he’s a chaotic force of nature with roots in real-life canine anarchy. The inspiration? Gunn’s own rescue dog, Ozu—a four-legged tornado of teeth, energy, and unpredictability.
That’s not an exaggeration. Gunn has openly admitted that Krypto’s personality was forged from the chaos of living with a dog who once bit his feet mid-phone call, destroyed his laptop, and waged war on household furniture. From that whirlwind of destruction emerged one of the most anticipated characters in the new DC Universe.
The Real-Life Inspiration: Ozu, the Rescue Dog with Attitude
Krypto may hail from Krypton in the comics, but in reality, he was born in a modest animal shelter. There, James Gunn encountered Ozu—a timid, underweight dog with one ear permanently perked in alarm. While other dogs barked and wagged for attention, Ozu cowered in the corner, wary of humans and the world around him.
Gunn, ever the contrarian, chose him immediately.
What followed was less a heartwarming adoption story and more a dark comedy about survival. Ozu didn’t just struggle with adjustment—he rejected domestic life entirely. His list of offenses includes:
- Biting Gunn’s feet during phone calls (prompting Gunn to sit on countertops to escape)
- Jumping onto counters just to continue the foot assault
- Obliterating every pair of shoes in the house
- Chewing through and ultimately consuming an entire laptop
“What if this terrible, maniac dog had superpowers? We’d be in real trouble,” Gunn mused—a throwaway comment that would spark Krypto’s cinematic reinvention.
That single question became the foundation of a superhero pet unlike any other: not perfectly trained, not effortlessly heroic, but deeply human in his flaws.
From Shelter Dog to Superdog: The Making of Krypto
Ozu may have been the soul of Krypto, but he wasn’t suited for on-screen performance. He wasn’t a trained actor. He wasn’t even close to housebroken. So Gunn and his team took a different approach: they scanned Ozu in 3D, transformed him into a sleek white bulldog (a nod to classic Krypto design), and scaled him up for CGI glory.
The physicality and movement in the film, however, come from Jolene—a professional canine performer described by Gunn as “every kind of respectable.” Jolene provided the clean, cinematic motions needed for action sequences and emotional beats. But the attitude? The mischievous glint in the eye? The unpredictable energy? That was 100% Ozu.

This hybrid approach allowed Gunn to preserve Ozu’s untamed spirit while ensuring Krypto could fly, fight, and emote on screen. The result is a character who feels both fantastical and grounded—a superhero pet with real emotional weight.
Krypto’s Role in Superman (2025): More Than Just Comic Relief
Krypto isn’t just comic relief or a gimmick to attract younger audiences. He serves as one of the film’s earliest emotional anchors. We meet him when Superman is at his lowest—wounded, isolated, and questioning his place in the world. Enter Krypto: loud, messy, and utterly undeterred by his owner’s melancholy.
He doesn’t offer quiet comfort. He offers chaos. He jumps on the bed, barks at nothing, knocks things over—and in doing so, pulls Superman back into life. That moment isn’t just funny; it’s healing. Krypto becomes a symbol of resilience, joy, and unconditional love.
And yes, he’s got powers. Flight. Super strength. Heat vision. Imagine giving all of Superman’s abilities to a dog who doesn’t understand personal space or property damage. That’s Krypto—equal parts protector and menace.

Krypto: Comics vs. Cinematic Reimagining
In DC Comics, Krypto first appeared in 1955 as Superman’s loyal companion from Krypton. He’s typically portrayed as disciplined, brave, and almost impossibly well-behaved—essentially a golden retriever with superpowers.
James Gunn’s version flips that script. This Krypto is unpredictable. He’s not fetching the newspaper; he’s laser-blasting villains mid-air. He’s not waiting patiently by the door; he’s tearing up the couch while flying in circles. He’s not Lassie—he’s the anti-Lassie.
And that’s what makes him compelling.
By embracing chaos and imperfection, Gunn has created a Krypto who feels alive. He’s not just a reflection of Superman—he challenges him. He forces him to laugh when he wants to brood, to play when he wants to isolate.
