Krypto the Superdog will appear in James Gunn’s upcoming “Superman,” the director confirmed on social media Tuesday. He made the announcement in honor of October being Adopt a Shelter Dog month.

“Krypto arrives on screens in Superman this summer,” Gunn wrote. “Krypto was inspired by our dog Ozu, who we adopted shortly after I started writing Superman. 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. It took a long time before he would even let us touch him. 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. What better time to debut the not-so-good-good-boy Krypto than #AdoptAShelterDog month.  Btw, Ozu today, is, fairly often, a very good boy.”

Krypto, a superpowered dog from Superman’s home planet Krypton, has appeared in dozens of animated DC films, but has never appeared in a live-action film. He’ll be making his debut with David Corenswet’s Man of Steel in Gunn’s movie next summer before joining Milly Alcock’s Kara Zor-El in “Supergirl: Woman of Tomorrow” from director Craig Gillespie, set to debut June 2026.

Since appearing in a 1955 DC Comics issue of “Superboy,” Krypto has always appeared as a white dog with gold collar and red cape that matches Superman. Just like the famous Kryptonian hero, Krypto has super strength, intelligence and senses. Dwayne Johnson previously voiced the canine in 2022’s “DC League of Super-Pets,” opposite Kevin Hart as Batman’s caped crusading canine Ace.
