The Supergirl trailer has just been released, and it’s got everyone speculating about what is wrong with Krypto. There’s a particularly emotional scene in which we see Kara crying while she pets Krypto’s head, and that moment really hits hard.
A lot of people might be confused by what is happening. However, those who have read comics may already have some answers.
Supergirl is going to the second film in the DCU after the restart with James Gunn. Not only does it need to push the story deeper into space and expand this universe we’re just getting to know, but it’s also continuing the journeys of both Kara and Krypto after their introduction in Superman.

What the Comics Tell Us
The movie is based on Supergirl: Woman of Tomorrow comic. As per the comic, Krypto gets hit by a poisoned arrow while fighting with Krem of the Yellow Hills, the main villain of the film.
Suppose you are thinking, How can it be so damaging? Well, he got hit on a planet with a red sun—a place where Kryptonians lose their powers.
The hit on Krypto becomes the entire plot of the movie. Kara, with the help of a young woman named Ruthye, will track Krem to get a sample of the poison so a cure can be made for the dying Krypto. Ruthye will help Kara, but her reasons are more personal: Krem murdered her father, and she wants revenge: two missions, one hunt.
So those emotional trailer shots of Kara with an ailing Krypto? They’re lifting this exact storyline. The movie is setting up that same desperate race against time to save everyone’s favorite super-dog.
The Comic Twist
If you started to panic, well, take a break. As in the comic, by the end, we learn that Krypto was not actually at death’s door the whole time. He was healing somewhere safe, and Supergirl knew about it.
The whole we need the poison sample thing is a bit of manipulation on Kara’s part. She was using the quest to help Ruthye process her grief and reconsider her thirst for vengeance, not because Krypto desperately needed saving.
It is one of those emotional moments that the comic delivers brilliantly, reframing everything you thought you understood about the journey.
Now, whether the Supergirl movie keeps this twist or decides to make Krypto’s situation genuinely life-threatening remains to be seen. They may stick with the comic version and deliver that same emotional complexity, or they may go darker and keep the stakes real throughout.
Either way, the trailer makes one thing crystal clear: Krypto’s condition is going to matter a lot in this story, and we are probably in for some tears along the way. The DCU is about to test just how much we care about that four-legged hero, and honestly, based on that one trailer scene alone, the answer is: a whole damn lot.
