Writer Nicole Perlman said last year that Carol’s origin will be changed for the Captain Marvel movie so that it doesn’t resemble Green Lantern’s as much, so perhaps turning to the Quantum Realm is the key to distinguishing her live action counterpart from the Emerald Knight.
Although there’s speculation that a non-powered Carol Danvers could debut next year in Avengers: Infinity War, her superhero origin story won’t unfold until Captain Marvel.
In the comics, Carol gained her abilities when she was shielded by an alien energy detonation by the Kree operative Mar-Vell, and she was subsequently turned into a human/Kree hybrid.
