From Ozu to Krypto: How James Gunn’s Real-Life Dog Inspired the Super Pup

When Superman (2025) soars into theaters on July 11, 2025, it will mark the dawn of the DC Universe’s (DCU) Chapter One: Gods and Monsters, directed and written by James Gunn, co-head of DC Studios. Among the film’s star-studded cast—David Corenswet as Superman, Rachel Brosnahan as Lois Lane, and Nicholas Hoult as Lex Luthor—one character is stealing hearts before the first frame: Krypto the Superdog. This fluffy, mischievous canine, making his live-action big-screen debut, isn’t just a nod to DC Comics’ lore but a deeply personal creation inspired by Gunn’s own rescue dog, Ozu. From a chaotic start in a hoarding situation to becoming the muse for a superpowered pup, Ozu’s journey mirrors the heartfelt and humorous tone of Superman. This article delves into the touching story of Ozu’s transformation, how it shaped Krypto’s on-screen persona, and why this tale of rescue and redemption resonates with fans. Drawing from Gunn’s own words and the buzz surrounding the film, we explore the real-life inspiration behind DC’s newest canine star.

Ozu’s Rough Beginnings

James Gunn and his wife, Jennifer Holland, adopted Ozu, a terrier-like mixed-breed dog, around the time Gunn began writing the Superman script in early 2022. Ozu’s early life was far from heroic. Rescued from a hoarding situation in a backyard with over 60 other dogs, Ozu had never known human contact and was deeply mistrustful. As Gunn shared in an October 2024 Instagram post, “Ozu, who came from a hoarding situation in a backyard with 60 other dogs & never knew human beings, was problematic to say the least. He immediately came in & destroyed our home, our shoes, our furniture—he even ate my laptop.” This destructive behavior, including chewing through an $8,000 laptop, as Gunn revealed at CinemaCon 2025, made Ozu a whirlwind of chaos in the Gunn household.

Ozu’s skittish nature and one perpetually upright ear gave him a distinctive, scrappy charm. Gunn recalled spotting Ozu in a kennel among louder, friendlier dogs and being drawn to his quirky appearance: “He kind of looked like my old dog on crack,” Gunn joked at CinemaCon, noting Ozu’s skinny frame and wild hair. The dog’s initial fear of humans meant it took months before he allowed Gunn or Holland to touch him, a process that required patience and love. This challenging adoption journey sparked a creative epiphany for Gunn: “I remember thinking, ‘Gosh, how difficult would life be if Ozu had superpowers?’—and thus Krypto came into the script & changed the shape of the story as Ozu was changing my life.”

From Chaos to Krypto: Crafting a Super Pup

Krypto the Superdog, first introduced in DC Comics’ Adventure Comics #210 in 1955, is traditionally depicted as a white Labrador Retriever or similar breed, a loyal Kryptonian canine with powers like flight, super-strength, and heat vision. Gunn’s version, however, breaks from this mold, embracing Ozu’s shaggy, mixed-breed look and unruly personality. The CGI model for Krypto was directly based on Ozu’s body, scanned in 3D and altered to white fur to align with comic book aesthetics, though retaining Ozu’s distinctive crooked ear and scrappy vibe. The character’s movements and mannerisms were informed by hundreds of video references of Ozu’s playful, sometimes destructive behavior, including his habit of biting Gunn’s feet.

While Ozu provided the inspiration, the on-screen Krypto’s performance came from a seasoned canine actor named Jolene, described by Gunn as “every kind of respectable.” Jolene’s trained movements brought Krypto’s superpowered antics to life, but the character’s chaotic, “not-so-good-good-boy” attitude is pure Ozu. Gunn emphasized this in a Q&A session, noting, “Krypto probably comes off as a better dog in the trailer than he is in the movie. Pretty terrible dog! You love him because he’s a dog and how can you not? And he’s got the cute, innocent eyes, but he’s a terrible dog.” This mischievous streak is evident in fan reactions on X, where users praised Krypto’s hyper, relatable behavior, with one commenting, “I know some people hated this depiction, but I think it’s a pretty perfect capture of exactly what a dog is like lmao.”

In the Superman trailer, Krypto steals the show in a poignant scene where a battered Superman, bloodied and stranded in the snow, whistles for his furry friend. Krypto arrives with super speed, excitedly licking Superman’s face before dragging him home by his cape. This moment, inspired by All-Star Superman’s iconic moon-gazing panel, underscores Krypto’s role as more than comic relief—he’s Superman’s emotional anchor, reflecting Ozu’s transformative impact on Gunn’s life. As Gunn told PEOPLE, “Krypto isn’t a punchline. He’s the first emotional beat in Superman. We meet him when Superman is at his lowest, injured, alone, and in danger. And in comes Krypto, this rowdy, annoying dog who refuses to let him wallow.”

Krypto’s Role in Superman and the DCU

Superman (2025) is not an origin story but a tale of Clark Kent balancing his Kryptonian heritage with his human upbringing, set in a world already teeming with superheroes like Hawkgirl, Mister Terrific, and The Engineer. Krypto’s inclusion grounds this epic narrative, humanizing Superman through their bond. Unlike the traditional comic book Krypto, who arrived on Earth as a test subject in Jor-El’s rocket, Gunn’s version may have a unique origin, possibly tied to Lex Luthor’s experiments, as speculated by fans on Reddit: “I really think Gunn will play the animal abuse/experiment angle again, I’m almost sure Krypto will be the result of LexCorp trying to create a Superman clone.” While Gunn has confirmed Krypto is Kryptonian, stating, “He’s an alien so he wouldn’t necessarily be exactly any one of those things [breeds],” the exact origin remains a mystery, adding intrigue to the film.

Krypto’s role extends beyond Superman. The character is pivotal in the comic Supergirl: Woman of Tomorrow, which the DCU is adapting into a 2026 film starring Milly Alcock. In the comic, Krypto is harmed by a villain, spurring Supergirl into action, and set photos suggest he may appear in the film, continuing his DCU arc. This connection ties Superman to the broader Chapter One: Gods and Monsters, where Krypto represents the “monsters” side—powerful yet unpredictable—complementing Superman’s godlike heroism. Gunn’s history of crafting compelling animal characters, like Rocket Raccoon in Guardians of the Galaxy, fuels excitement for Krypto, with ScreenRant noting, “Gunn’s track record with animals has made me incredibly excited for whatever he does with Krypto.”

The Heart of the Story: Rescue and Redemption

Ozu’s influence on Superman goes beyond Krypto’s appearance and behavior—it’s a testament to the power of rescue and second chances. Gunn, a noted animal lover, used his platform to promote Adopt a Shelter Dog Month in October 2024, sharing Krypto’s first look to encourage pet adoption. Fans on X responded warmly, with comments like, “This is the sweetest thing I’ve ever heard oh my god,” and “Adopting a dog, super or not, is always heroic,” from Batman: The Animated Series writer Paul Dini. Ozu’s transformation from a fearful, destructive pup to a beloved family member mirrors the film’s themes of hope and kindness, as Gunn noted, “Ozu loves my 13-year-old cat, Emily…she puts up with Ozu and loves to play with him.”

The story resonated with audiences, especially when Gunn shared a May 2025 video of Ozu barking wildly at Krypto on-screen, seemingly trying to “murder himself.” This adorable reaction, where Ozu recognized the whistle from the Superman trailer and rushed to attack the screen, went viral, with fans on Reddit calling it “the cutest thing from Krypton.” Gunn even tested Ozu’s reaction further, posting, “I wanted to see if Ozu would bark at Ozu barking at Krypto, and then would Ozu bark at Ozu barking at Ozu barking at Superman. And, sure enough…” This playful interaction underscores the real-life bond that shaped Krypto’s chaotic yet lovable persona.

Fan Reactions and Controversies

While Krypto has won over many fans, some expressed concerns about Gunn’s choices. On Reddit’s r/comicbooks, users debated Krypto’s breed, with one noting, “Ya its pretty egocentric to make it a dog breed he has owned in the past,” preferring the traditional Labrador look. Others criticized the DCU’s crowded cast, arguing, “The problem with flooding Superman’s world with so many other super beings is it makes Superman himself much less super.” Disgruntled Snyder fans, still loyal to the DCEU’s darker tone, took to the “Snyder Cut” subreddit to plan Santana Claus, planning to post spoilers and negative reviews on release day, prompting Gunn’s lighthearted response, “Lol I think we’ll survive.”

Despite these criticisms, the majority of reactions are positive, with fans praising Krypto’s unique, Ozu-inspired personality. One Reddit user wrote, “Superman caring for a less-than-perfect dog only reflects better on Clark, not worse,” highlighting the character’s emotional depth. Gunn’s personal touch has also fueled hype, with Empire noting that Krypto’s inclusion makes the film “a new dawn for DC films.”

The Bigger Picture: Gunn’s Vision for Superman

Gunn’s Superman aims to balance epic action, humor, and heart, with Krypto as a key emotional element. The film’s grounded yet fantastical world, where superheroes coexist with real human struggles, reflects Gunn’s signature style—seen in Guardians of the Galaxy—and Ozu’s influence adds a layer of authenticity. As Cinemablend observed, “If Krypto in Superman was inspired by Ozu’s adjustment to living with James Gunn, I have to assume that the superpowered pooch might be causing some chaos for David Corenswet’s Clark Kent.” This chaos, tempered by loyalty, mirrors the film’s theme of finding hope amid adversity.

Krypto’s role also sets up the DCU’s future, with potential ties to Supergirl and other Chapter One projects like Clayface and Lanterns. By grounding Superman’s story in a personal, relatable bond, Gunn ensures the DCU kicks off with a film that’s both epic and intimate, as he shared in a PEOPLE interview: “This movie is about a loose term of the word a human being and who he is as a person and virtually struggling in his day-to-day life.”

Conclusion

From a destructive rescue pup to a superpowered cinematic icon, Ozu’s journey to becoming Krypto the Superdog is a heartwarming tale of redemption that defines James Gunn’s Superman (2025). Ozu’s chaotic beginnings, marked by chewed laptops and mistrust, inspired a Krypto who’s far from the perfect Labrador of the comics—a scrappy, mischievous Kryptonian dog who brings humor and heart to the DCU. By modeling Krypto’s appearance and behavior on Ozu, Gunn infused the character with authenticity, making him a fan-favorite emotional anchor in a film about hope and humanity. The viral buzz around Ozu’s on-screen reactions and Gunn’s advocacy for pet adoption amplify the story’s impact, resonating with fans and animal lovers alike. As the DCU launches with Superman on July 11, 2025, Krypto’s Ozu-inspired antics promise to steal the show, setting a vibrant, heartfelt tone for Chapter One: Gods and Monsters. Whether barking at his own image or flying alongside Superman, Krypto proves that even the most unlikely heroes can change the shape of a story—and a life.
