The Marvels May Have Just Teased A Massive X-Men Bombshell In A Tiny Trailer Detail

As a sequel to three different Marvel Cinematic Universe projects — "Captain Marvel," "WandaVision," and "Ms. Marvel" — "The Marvels" has a lot of ground to cover. In addition to getting fans up to speed on Captain Marvel's (Brie Larson) latest space-faring exploits, it will also give them updates on Kamala Khan (Iman Vellani) and Monica Rambeau's (Teyonah Parris) developing powers. In doing so, the film also offers up an action-packed story where all three heroines' powers have become entangled as they battle a new cosmic threat in the form of Dar-Benn (Zawe Ashton).

On top of all of that, "The Marvels" may hint at the arrival of one of Marvel Comics' most famous factions: the X-Men. A new TV spot for the feature, which highlights the titular characters and the importance of their latest mission, teases the future of the MCU. Monica mentions that another reality is seeping into the one they reside in, hinting at multiversal collapse. Meanwhile, the on-screen text tells fans to be present for is on the way. When the text reading "What Comes Next" disappears, the letter X sticks around just a bit longer than the letters around it. Assuming this wasn't an editing error, this could be a subtle tease that the X-Men are on the way.

If you think that's far-fetched, consider that there was another subtle X-Men nod in one of the MCU properties that ties directly into "The Marvels." 

Hints that the X-Men may appear in the MCU have been minimal at best. For instance, Fox "X-Men" franchise favorite Evan Peters returned as Quicksilver (who actually turned out to be a random guy named Ralph Bohner) on "WandaVision," and Sir Patrick Stewart appeared as an alternate universe version of Professor Charles Xavier in "Doctor Strange in the Multiverse of Madness." Of course, these examples don't seem to connect to the "Marvels" story too well. However, there is one more subtle X-Men nod that does stem from a story closely tied to that movie.

In the 6th episode of "Ms. Marvel," we learn a bit about how Kamala's new powers work through her seemingly magical bangle. Her friend Bruno Carrelli (Matt Lintz) shares with her that, upon studying her light construct abilities, it's not just the bangle that allows her to use them. Rather, it's her genetics that serve as the secret ingredient to activating them. Bruno specifically describes it as a mutation, which prompts the theme for the "X-Men '97" animated series to play. Thus, the MCU's take on Kamala seems to cast her as a mutant rather than an Inhuman like she is in the comics, and that would mean that mutants are officially confirmed to exist in the main MCU timeline.

So, how could this tie into "The Marvels"? Will Kamala team up with Monica Rambeau and Captain Marvel to seek out other mutants like her? Or will the X-Men themselves finally make their presence felt in the MCU, trying to recruit her to the team? We'll just have to wait and see when "The Marvels" flies into theaters on November 10.
