The dog in the new Superman movie is a Supermess—and that’s the point
Krypto energy is contagious—and we’re kind of here for it
Ready or not, get ready for Krypto
The new Superman movie gives us a superdog who’s less “man’s best friend” and more like a cross between the Tasmanian Devil and a gremlin.
The trailer tricks you—Krypto pads solemnly into the snow like a noble companion, ready to rescue his wounded owner.
What we get in the film is decidedly not that. Krypto is chaotic, untrained, and kind of a menace. And weirdly, that’s exactly why I loved him. Plus—he actually did come when he was called. So who’s the good boy now?
A supermess of a dog, with main character energy
This isn’t your standard golden retriever in a cape. Krypto is based on James Gunn’s real-life rescue dog—a mutt pulled from a backyard hoarding situation, one of sixty. That dog, reportedly, once ate his laptop. Not metaphorically, but actually ate it.
So what is Krypto like in the movie? He’s destructive. He doesn’t listen. He causes problems. He plays fetch (or, more accurately, crunch) with Mister Terrific’s T-Spheres, even when nobody else is playing. And the movie doesn’t sugarcoat it. At one point, Superman mutters, “He’s just a dog—not even a good one.” That line is kind of the heart of the film.
Not a Good Boy—but a real one
Krypto isn’t a perfectly trained sidekick. He’s a creature of instinct, not obedience. He knocks things over. He ignores commands. He’s more likely to steal the moment than save the day—until, of course, he does save the day, in his own strange, slightly unhinged way.
When the heroes are down, Krypto crashes into the final battle with zero restraint—lunging at Ultraman, tackling him mid-air, biting with wild energy and pure heart. It’s messy and loud, and somehow, it’s exactly what is needed.
It’s a bold creative choice in a movie that could’ve gone full heartstrings and fluff—and instead gives us emotional honesty, comedic mayhem, and a little off-the-rails joy.
Some of the action sequences happen so fast that you may not even be sure what Krypto is doing, much like your experience with your own dog chewing the ball he just fetched, or chasing a squirrel. Instinctive joy, with no thought.
Why this matters more than you might think
Krypto’s bad behavior isn’t just comic relief. It’s a quiet revelation, because if even Superman can love a creature this chaotic, maybe the bar for being lovable isn’t perfection. Maybe it’s more about presence, and heart.
Krypto is reckless and disobedient, but he’s still loved, protected, and belongs. And honestly, that speaks louder to what real life should be: not earned, not perfected, just accepted.
He’s not “just a dog”—he’s the whole metaphor
Krypto is a stand-in for all the untrainable, inconvenient, wildly loyal beings in our lives—whether they’re dogs, friends, family, or anyone who doesn’t quite fit the mold.
And in a subtle twist, he’s not even Superman’s dog: he belongs to Superman’s cousin Kara, otherwise known as Supergirl. Superman is just taking care of Krypto temporarily, but he accepts him anyway, because that’s what love is: not ownership, but choice.
Krypto, in many ways, mirrors Kara. He’s reactive, unpredictable, and full of feeling. He doesn’t follow the rules, he doesn’t fit the mold, and like Kara, he doesn’t have to be fixed or softened to be valued. The movie doesn’t redeem him with a makeover montage. He doesn’t learn tricks or get a growth arc. His unruliness stays, and still Superman stands by him. Not because he’s perfect, but because he was chosen.
Krypto doesn’t have to be good to belong—he just has to be. Imperfectly perfect.
The subversive charm of being “not good”
When Superman tells Lois that Krypto is “not even a good one,” it lands like a joke, but also like a quiet statement of fact. And the best part is that it doesn’t matter, because being obedient is not a requirement for being important.
In this story, being not good, not obedient, and not safe is exactly what earns Krypto a place in the frame. And sometimes, that’s more than enough.
