In The Marvels' final act, Monica Rambeau finds herself stranded in an alternate universe after repairing a tear in the fabric of reality. Waking up to find the X-Men's Beast staring back at her, the former S.W.O.R.D. agent is also met by a younger Variant of her mother, Maria, who is this world's Binary.
In the comics, that mantle was held by Carol Danvers, but the nature of the Multiverse allowed Marvel Studios to come up with something a little different than Monica simply meeting a different version of her Aunt.
With the X-Men set to make an appearance in Deadpool 3, we're anticipating Binary potentially returning there instead of being part of yet another iteration of the team.
Talking to Screen Rant, actress Lashana Lynch broke her silence on The Marvels' post-credits scene and admitted to having been largely kept in the dark when it came to the question of which world she's on (remember, she played a Captain Marvel Variant in Doctor Strange in the Multiverse of Madness).
"I did know going into the movie. I didn't know what would happen next. I don't know anything, literally. Every single increment of the character has been play-by-play, so I knew about Captain Marvel, then I knew about Doctor Strange, and then I knew about The Marvels."
"I didn't even get the script for that, I just had those moments. I know what you know, and that's it."
In the comics, Binary's story - and her connection to the X-Men - is a little complicated. When Carol returned to Earth after a tricky mission, she battled Rogue (who was working for her mother, Mystique, at the time) and ended up in a coma after the villain siphoned away her powers.
When she woke up, Carol had lost many of her memories but stuck around Xavier’s School for Gifted Youngsters in the hope Professor X might help restore them. Later choosing to remain with the X-Men rather than rejoin The Avengers, she became an unofficial member of the team for a time and even discovered she had latent mutant genes.
How much of this we'll see in the MCU remains to be seen, but a Captain Marvel Variant being part of the X-Men is comic-accurate.
"It is my hope that you will [see him again]," Grammer recently said of his surprise MCU debut. "I can say with a certain amount of confidence that you will. I would love to." The actor went on to say he'd been "very pleased" with the response to his appearance in The Marvels and revealed that "a lot of people got in touch" with him after they saw it.
"I’ve always wanted to play him again," the Frasier star concluded. "I see him as an extraordinary character, a real character of gravitas and importance in our culture. I’m delighted Beast is back and hope he’s back in a real way."
