Rebecca Romijn Is Officially Back As Mystique and the ‘Avengers: Doomsday’ First Look Has Fans Talking

Marvel fans finally got what they had been waiting years for this week, a proper look at Rebecca Romijn back in blue as Mystique for ‘Avengers: Doomsday‘. The road back to the MCU for the original X-Men cast has been building for years, ever since Robert Downey Jr’s surprise reveal as Doctor Doom reshaped the direction of the franchise.

The new footage confirms something that had been rumored for months, and now the internet has plenty to say about it. The shape shifting mutant is being played by Rebecca Romijn, who is reprising the role from the original X-Men trilogy.

Rebecca Romijn Returns As Mystique

Rebecca Romijn is finally back after playing the shape shifting character in the first three X-Men films, marking her return to the role that made her a household name. Reports have also claimed she will finally get a comic accurate suit for this outing. That detail alone has fans buzzing, since Mystique’s look on screen has always been a point of discussion among longtime followers of the character.

Her full credits list the role as Raven Darkhölme, more widely known as Mystique, with the project currently sitting in post production for its 2026 release. That is a fitting full circle moment for an actress who has spent over two decades tied to this character in the public imagination.

Notably, this means Jennifer Lawrence is not reprising her version of Mystique from the more recent X-Men films for this crossover. Instead, Marvel appears to be leaning into nostalgia by bringing back the actress most associated with the character’s earliest cinematic appearances.

The ‘Avengers: Doomsday’ Trailer First Look Sparks Debate

The freshly released footage has not gone over smoothly with everyone. Fans are frustrated over Mystique’s new look in the trailer, specifically her white X-Men costume paired with shorter red hair. Some viewers have suggested the production team should have styled the wig differently.

Reactions to the wig itself have been especially harsh online, with some viewers arguing the styling does not do the character justice compared to her classic slicked back look from the original trilogy. Others online have taken the opposite stance. Some have pushed back, insisting the newer footage looks far better than leaked images that circulated months earlier.

Beyond the hair debate, this version of Mystique appears to be leaning further into her comic book roots than any previous film outing, complete with a visible skull headpiece detail across the design. That shift toward comic accuracy seems to be a deliberate choice on the part of the filmmakers, even if the execution is dividing opinion for now.

One moment in particular has become a talking point across social media. A widely shared clip shows Mystique catching Yelena Belova’s baton and shifting her appearance into that of the New Avengers leader, a beat that has quickly become one of the most discussed from the new footage.

The X-Men Reunion Cast in ‘Avengers: Doomsday’

Mystique is far from the only familiar face returning for this crossover event. A livestream stunt in March 2025 confirmed the cast, which includes Patrick Stewart as Charles Xavier, Alan Cumming as Nightcrawler, Romijn as Mystique, James Marsden as Cyclops and Kelsey Grammer as Beast, all reprising their roles from the Fox Marvel movies.

Besides Mystique, Doomsday also brings back James Marsden as Cyclops, who will reunite with Patrick Stewart, Ian McKellen, and Alan Cumming as Professor X, Magneto, and Nightcrawler. The X-Men group will also be joined by Channing Tatum’s Gambit, who first appeared in Deadpool and Wolverine.

There is also a bittersweet note attached to this reunion for longtime fans. It has been rumored that this film may be Stewart’s final role, with the veteran actor said to be stepping away after a legendary decades long career, and Rebecca Romijn also briefly appears alongside him in the newly released footage.

‘Avengers: Doomsday’ Release Date and What Comes Next

Marvel has kept the marketing steady in the lead up to release. ‘Avengers Doomsday’ is set to arrive in theaters on December 18, and the film’s marketing machine has been ramping up steadily ahead of that date.

For fans who have always been confused about Mystique’s near constant nude appearance in earlier films, the promise of a fuller comic accurate suit this time around seems to be addressing a long running point of discussion among the fandom. Whether that translates into a design audiences fully embrace remains to be seen once more footage rolls out.

There is also chatter about who could eventually inherit the role down the line. Marvel Studios has reportedly been rumored to want Margot Robbie to play Mystique in the future, though nothing has been confirmed on that front. For now, all eyes remain on Romijn’s comeback and how her Mystique fits into the sprawling new ensemble.

With the wig debate still raging and the comic accurate suit yet to be fully revealed, how do you think Romijn’s Mystique will hold up once ‘Avengers: Doomsday’ finally hits theaters?
