As of now, Krypto’s exact role in Superman is still unclear, but Gunn included a brief teaser in his X post that shows Superman and Krypto sitting side by side, enjoying the view of Earth from afar , resting on what appears to be the moon. After making his comic book debut in Adventure Comics #210 in March 1955, Krypto has gone through several iterations over the years. More recently, Krypto often appears as Superman’s pet dog, usually depicted as a white dog of various breeds.
In addition to his announcement, Gunn made a direct reference to Adopt a Shelter Dog Month, an event sponsored by the American Society for the Prevention of Cruelty to Animals (ASPCA). The event, which takes place every October, aims to promote the adoption of dogs from local shelters. According to the ASPCA, more than three million dogs enter shelters each year.
