The first trailer for the Craig Gillespie-directed DCU movie Supergirl was released back in December, and fans were thrilled. However, the newest ad has people even more hyped thanks to one very special addition: Krypto.
Krypto the Superdog made his DCU debut last year in James Gunn's Superman. The chaotic canine was a highlight of the film, and fans have been eager to see him again.

In Superman, it's revealed that Superman (David Corenswet) was dog-sitting Krypto for his cousin, Kara/Supergirl (Milly Alcock).
The new Super Bowl trailer for Supergirl opens with a flashback of Kara finding Krypto as a puppy. Unsurprisingly, it's freaking adorable. You can watch the trailer below:
The fans react to new Supergirl trailer
Based on the comic Supergirl: Woman of Tomorrow by Tom King and Bilquis Evely, the upcoming DC film is set to follow the titular character as she "reluctantly joins forces with an unlikely companion on an epic, interstellar journey of vengeance and justice."
Fans are excited to see this comic story come to life almost as much as they're excited to see Krypto again. Some trailer reactions from fans below:

This isn't his first DC appearance.
Warner Bros covering the puppy adoption fees is honestly way better marketing for Supergirl than a regular Superbowl ad https://t.co/LCETLC7NZB
