The new teaser trailer for 2025 Superman just broke a 69-year Superman movie trend. The new DCU teaser is full of exciting action, showing for the first time David Corenswet's Clark Kent, Rachel Brosnahan's Lois Lane, Nicolas Hoult's Lex Luthor and more. However, the debut of one classic (and adorable) Superman ally in particular is very exciting.
James Gunn and DC Studios have officially released the first teaser trailer for Superman which is set to premiere in July 2025. Offering a new take on the Man of Steel in a new DC cinematic universe, there's a lot to be excited about. However, Superman may have been somewhat overshadowed by his four-legged ally, who breaks a grand Superman tradition with his first live-action film debut.
DCU Superman trailer confirms a super-powered Krypto will appear in the film
Kal-El's adorable superdog
Shown at the beginning of the new teaser, none other than Krypto the Superdog comes running at super speed when called by a beaten and broken Superman. Taking Kal-El's cape in his mouth, Krypto is later shown in the trailer pulling Superman and carrying him back home. Wearing his own red cape and yellow collar, Krypto's debut is incredibly adorable, and it has been confirmed by James Gunn that Krypto is based on his own dog named Ozu, both in appearance and a similar breed (and perhaps also in mannerisms).
In the comics and other media, Krypto is often portrayed as a very good and loyal boy. However, it was teased by Gunn that Superman Krypto may have some growing/training pains, having a “complicated” relationship with Superman at first. Either way, this new teaser certainly appears to show Krypto being a very good boy, leading Kal-El to safety as the first live-action Kryptonian canine to grace the big screen.
Why Krypto's Superman debut is a big deal for DC and the DC Universe
Big news in live-action Superman movies
Krypto has been shown on screen before, having been one of the protagonists of the 2022 animated film League of Super-Pets where Krypto was voiced by Dwayne Johnson, as well as on television in the live-action Titans series alongside Conner Kent's Superboy. However, Krypto's debut in a live-action film is big news in 2025 Supermanand it will be very exciting to see how his story continues. After all, Krypto is also likely to have a role in 2026 Supergirl: Woman of Tomorrow starring Milly Alcock as Kara Zor-El, as he appeared in the original comic book of the same name.
