Captain Marvel smashed the box office with its fun introduction to the most powerful hero in the Marvel Cinematic Universe, and knowing how Marvel works it's only a matter of time until a sequel is announced.

The movie did a good job establishing Carol's powers, but certain elements of its plot also opened the door for two very specific Marvel heroes to show up later on in Carol's story. One was even in the movie, hiding in plain sight!

These are the two most likely female heroes to join in on Carol's later adventures:

Monica Rambeau, A.K.A Photon

The first and most obvious nod to a future Marvel heroine is Monica Rambeau, the 11-year-old daughter of Carol’s BFF Maria Rambeau. While Maria is a badass pilot in the movie, Monica is the known alias of a Marvel hero who has also gone by the name Captain Marvel in addition to using the aliases Pulsar, Spectrum, and Photon.

In the comics, Monica gets her powers after some interdimensional technology explodes and infuses her with the ability to transform into a being of pure energy. She becomes immensely powerful, joins the Avengers, and later becomes their leader.

The Monica of Captain Marvel is not superpowered yet, but she is a spunky and determined girl who plays a huge part in helping Carol Danvers remember who she is. She helps design Carol’s new suit and impresses Nick Fury with her ambition to build rockets and one day fly. She’s also great at getting along with aliens, which is a great skill for any Avenger to have.

Since Monica is 11 in Captain Marvel, she’d be in her mid-30s in the MCU’s present timeline and prime for an appearance in a modern-day Captain Marvel sequel or other Phase 5 film.

As for which heroic alias Monica may take on in the MCU, there is one little hint in Captain Marvel. Her mom Maria’s call signal in the Air Force was revealed to be “Photon,” just as Carol’s was seen to be ‘Avenger.” Maybe Monica will take on her mom’s old sign so Photon and Avenger can fly together again?

Kamala Khan, A.K.A. Ms. Marvel

The other most likely option for another female hero that Captain Marvel may hint at is Kamala Khan, who does not appear at all in the movie but is closely linked with Carol in the comics. Kamala is an Inhuman, a type of super-person that has been explored in Agents of Shield, and her power is being able to manipulate her body into fantastic proportions — including making her limbs long enough to reach any enemy and enlarging her fists to the size of wrecking balls.

Kamala is connected to Carol by virtue of being her biggest fan. In the comics, Carol Danvers had the moniker Ms. Marvel before becoming Captain Marvel. When she left the Ms. Marvel name behind, Kamala picked it right back up and fought crime under that alias.

Brie Larson already brought Kamala up at a press conference for Captain Marvel, and said that having Ms. Marvel in the next movie was “the goal,” so there’s a strong possibility that Khan could turn up in Phase 5. Since she is a teen hero from just outside New York City, it might be nice to have her buddy up with Spider-Man.

It’s telling that both of the big heroes Captain Marvel brings closer to the Marvel Cinematic universe are women of color — Monica is a black woman and Kamala is a Pakistani Muslim. As the MCU continues to change and shift focus, it’s important for the franchise to learn from its earlier successes while also making an effort to include more diverse heroes that represent more of its audience.

If Carol Danvers taking her best friend’s daughter under her wing and inspiring a Pakistani teenager is what it takes to get more women of color in the MCU, then so be it. Bring on the new age of heroes.
