Carol Danvers' origins as a superhero won't be the focus of Captain Marvel, but her background - specifically her genetic connection to the Kree - will play a role in the film, according to star Brie Larson.
“You have this Kree part of her that’s unemotional, that is an amazing fighter and competitive,” Larson told Entertainment Weekly. “Then there’s this human part of her that is flawed but is also the thing that she ends up leading by. It’s the thing that gets her in trouble, but it’s also the thing that makes her great. And those two sides warring against each other is what makes her her.”
In comic books, Carol Danvers is also part Kree - but not by birth. Instead, she's a human Air Force officer who is genetically combined with the Kree hero Mar-Vell when the pair are caught in the explosion of the Psyche-Magnitron, a Kree weapon. This is what leads to Carol developing super powers, and also leaves her with hybrid Kree/human DNA.
It's unclear how closely the origin of Carol's powers will follow her comic book roots in Captain Marvel, but her Kree heritage will be enough to get her a spot on the elite Kree military team known as Star Force in the film.
Captain Marvel is due out in theaters March 8, 2019.
