The post-credits scene for the DC League of Super-Pets was co-starred by Dwayne Johnson.

The animated family picture DC League of Super-Pets, in which Dwayne Johnson portrays Krypto the Super Dog, marked the beginning of his partnership with DC in 2022. The film has been a pleasant surprise for several reviewers and moviegoers, in part because it is a family-friendly sendoff to the DC Universe.
Dwayne Johnson published some screenshots of the movie’s post-credits scene last week. On his Instagram feed, the official sequence has now been revealed. You can see how this scene previews both his much-anticipated feature Black Adam and that DC antihero’s dog, Anubis:
Dwayne Johnson recognizes in the sequence that he has provided voices for three separate characters—Krypto, Anubis, and Black Adam—in the film. This amusing little scene is just one more example of how dedicated the former wrestler turned movie star is to the DC Universe, whether it be in animated form or in live-action with his eagerly awaited debut in October.
Currently showing in cinemas, Black Adam will be released on October 21.
