Krypto may be a Superdog, but he is definitely a bad dog in the DC Universe. I say that lovingly. The dog trashed the Fortress of Solitude in James Gunn's Superman movie last summer! He's adorable and lovably loyal, but he is a ball of chaos with a prey drive through the roof. Thankfully, he proved himself to be capable of Good Boy Acts when he attacked Lex Luthor.

As it turns out, the screenwriter of the Supergirl movie coming out later this month, Ana Nogueira, can relate a lot to the dynamic between Kara and Krypto. In an interview with Empire magazine, Nogueira looked back on her relationship with her own pup. "My dog, who passed a few years ago, was so bad and I loved him so much... James [Gunn] and I bonded over having a mess of a dog and how it's perfect for Kara. She's also kind of a mess and wouldn't know how to train a dog," Nogueira said.

It seems like James Gunn has plenty of love for bad dogs, considering that Cosmo the Spacedog from Guardians of the Galaxy Vol. 3 had a knee-jerk reaction whenever anyone said she was a bad dog. In case you need reminding, even the bad dogs of the world (and universe) still need love.

It's also worth noting that Krypto is modeled after James Gunn's real-life dog, Ozu. So truly, DC Studios is a home for dog lovers. Let's just hope we get to see Streaky the Supercat sometime soon.

Supergirl will be released in theaters on June 26, 2026.
