WARNING: The following article contains major spoilers for Avengers: Infinity War, in theaters now.
With the monumental reveal of the Captain Marvel concept art during last summer's Comic-Con International in San Diego, speculation immediately began as to whether she would appear during Avengers: Infinity War in all her red, blue and gold glory.
The art showed her fighting off iconic Marvel villains the Skrulls, and given we’ve already been introduced to the Kree in multiple Marvel properties thanks to Guardians of the Galaxy and Agents of S.H.I.E.L.D., clearly, the stage has been set for an adaptation of the Kree-Skrull War from the comics.
But let’s get onto the big question: Where the heck was Captain Marvel? We’ll repeat it one more time – spoilers ahead for Infinity War and the film's post-credits scene.
Unfortunately, Carol Danvers doesn’t appear in Avengers: Infinity War. It’s a shame, since we do know that she actually shot footage alongside other members of the cast. Specifically, she shot scenes with Josh Brolin, which indicates that she had some sort of confrontation with Thanos. And although we’re disappointed she didn’t make her debut, there is a very specific reason why: She’s the back-up. Captain Marvel is the one that Nick Fury calls for help when things get too rough even for him, and in the post-credits scene, we're given a small tease for her solo film.
When Maria Hill disappears alongside other civilians, Nick Fury quickly grabs a device that sends out a signal before he too disappears, a device that displays the iconic star logo for Carol Danvers' costumed persona. Nick Fury has called for help, and Captain Marvel is coming to save the Marvel Cinematic Universe.
