Marvel fans can’t stop talking — could Millie Bobby Brown really be joining the X-Men? The rumor mill is in overdrive, and if it turns out to be true, it could shake up the Marvel Cinematic Universe in a huge way. But here’s the big question: Which mutant would be the perfect fit for the Stranger Things actress? The guesses are flying, and some of them might really surprise you.
The MCU just can’t stop growing, constantly pulling new heroes, villains, and teams into its orbit. With Marvel’s upcoming X-Men reboot on the horizon, fans are anxiously waiting to see who will step into the iconic roles. Recent reports from ComicBookMovie suggest that Millie Bobby Brown — best known for her telekinetic powers as Eleven in Stranger Things — might be in talks to join the film. Rumor has it she could portray Rogue, Jean Grey, or Shadowcat. All exciting options, but one seems to fit her unique strengths the best.
Here’s where it gets interesting: Millie has already mastered the brooding, mind-powered hero archetype through years of playing Eleven. So maybe it’s time to see her try something completely different. Imagine her as Kitty Pryde — the quick-witted, brave young mutant who can phase through solid matter. It would be a fresh direction that lets her break away from familiar powers while showcasing a more kinetic, physically active role.
Fans have actually been campaigning for Brown as Kitty Pryde for years, pointing out her perfect mix of youthful intelligence and intensity. After all, she’s built an impressive sci-fi résumé, starring in Godzilla, The Electric State, and the Enola Holmes movies. And with Stranger Things ending after its fifth season, the timing couldn’t be better for her to join another blockbuster franchise.
Kitty Pryde has long been a beloved member of the X-Men, appearing in comics, animated series, and several live-action films. Elliot Page portrayed her memorably in X-Men: The Last Stand and Days of Future Past, but the character never got the spotlight she truly deserves. A reboot could finally change that — and a rising star like Brown could easily anchor that story. Still, none of this is confirmed, which makes the speculation even more fun. Who will make up Jake Schreier’s new X-Men lineup? That’s the question driving Marvel fans wild.
Of course, there’s also chatter about Brown possibly taking on Rogue instead — another electrifying choice. Rogue’s mix of flight, super strength, and life-draining touch offers plenty of cinematic potential. But if she were to embody Rogue, that might set the stage for an eventual crossover with Captain Marvel, adding even more layers to the MCU’s interconnected storytelling.
Right now, it’s all whispers and wish lists. Nothing has been finalized, and neither Brown nor Marvel has confirmed any deal. But that hasn’t stopped audiences from imagining how she’d look in the MCU’s next big ensemble. The official release date for the new X-Men movie is currently set for May 5, 2028, while Spider-Man: Brand New Day will hit theaters sooner, in July 2026. Until then, fans can still catch Brown in Stranger Things on Netflix and dream about her next big role.
Here’s a thought: Would Millie Bobby Brown be better off playing a brand-new mutant, rather than a recast of an existing one? Or is Kitty Pryde exactly the kind of character she was born to bring back to life? Let’s hear your takes — who do you think she should play in Marvel’s mutant future?
