With all this being said, it’s important to note the person may not be Binary. It looks like they’re wearing a superhero suit, and while it’s in the same color pattern as Binary, she doesn’t wear an outfit per se. She’s made of pure energy, so her costume is just … her. It’s possible the character’s origins and abilities could change if she’s introduced in the MCU where it’s just a person with energy-based powers who does wear a suit, but that remains to be seen.
Additionally, if that is actually Binary, it’d be interesting to see if they’re connected to Captain Marvel in any way. Would “The Marvels” want to spend time explaining how Carol Danvers diverged from her powers to create a whole new entity? It wouldn’t be the weirdest thing in a movie where there’s an alien species of cats that also turn into Lovecraftian monsters, but it may be a step too far for some.
The final theory of whether this is Binary concerns the multiverse, which seems to be the case with anything in pop culture these days. The current chapter of the MCU is known as the Multiverse Saga, but there haven’t been a ton of movies and Disney+ series exploring alternate realities so far. “The Marvels” could add to the saga by introducing a Carol Danvers from another universe who’s taken on the title of Binary. Anything’s on the table at this point, and audiences will figure out who the costumed figure is when “The Marvels” comes out in theaters on November 10.
