On Tuesday, director James Gunn shared that Krypto the Superdog will appear in his upcoming Superman. He made the announcement in honour of October being Adopt a Shelter Dog month, Variety reported. "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," Gunn said. James Gunn's Superman Legacy Gets New Title; Film to Arrive in Theatres in July 2025 (See Pic).

"He immediately came in and 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." Superman Legacy: James Gunn Shares First Cast Photo After Table Read with David Corenswet, Rachel Brosnahan, and Nicholas Hoult.
