Krypto the Superdog is more than Supergirl's sidekick in new teaser

Krypto the Superdog is emerging as an unexpected standout in the expanding DC Universe, with fans and insiders alike hailing the superpowered pup as the true scene-stealer of the franchise. A recent tease connected to the upcoming Supergirl film has reignited excitement around Krypto, with the character being affectionately described as the “main character of the whole universe.”

The teaser highlights Krypto’s growing presence alongside Milly Alcock’s Supergirl, positioning the iconic dog as more than just a sidekick. His playful, chaotic energy adds levity to the story while underscoring his importance within the larger DC narrative. Rather than serving solely as comic relief, Krypto appears to play a meaningful role in shaping the emotional tone of the film.

Krypto first captured audience attention with his introduction in Superman, where his super-strength, speed and mischievous personality quickly made him a fan favorite. Under Earth’s yellow sun, the dog shares abilities similar to Superman’s, making him both powerful and unpredictable on screen.

Director James Gunn has previously shared that Krypto’s characterization was inspired by his own rescue dog, lending a personal and relatable touch to the CGI creation. That influence is reflected in the character’s blend of loyalty, chaos and heart, which has resonated strongly with viewers.

With Supergirl set for release in 2026, Krypto’s elevated presence signals a shift in how the DC Universe is embracing its more unconventional heroes. As anticipation builds, the superdog’s rise suggests he may become one of the most beloved figures in the franchise’s next chapter.
