For nearly 70s years, Krypto has been Superman's loyal companion and a very good boy. Before he arrives in the cinematic DCU, read about his comic book history.

In a touching story shared on social media, Gunn wrote how "Krypto came into the script & changed the shape of the story as Ozu was changing my life."

Gunn shared this sneak peek at Superman 's Krypto with his whopping 2.8 million followers on Instagram. He regularly uses social media to shut down rumors, and communicate directly with the fandom. And that includes the story of adopting Ozu, and how his own pooch inspired the character of Superman's dog.
