Mystique in Avengers: Doomsday Trailer.

Rebecca Romijn is officially reprising her role as Mystique (Raven Darkhölme) in the newly released official trailer for Avengers: Doomsday. Marvel Studios launched the trailer publicly on July 20, 2026, confirming that the legacy Fox X-Men characters are crossing over directly into the MCU.

Her new look includes vibrantly styled, shorter red hair.

Yelena Belova Face-off: The trailer highlights an action sequence where Mystique intercepts a baton thrown by Yelena Belova (Florence Pugh) and effortlessly replicates her form.

Comic-Accurate Suit: Moving away from the textured, head-to-toe blue scales of the Fox films, Mystique is shown wearing her classic white, comic-accurate attire.

While the crossover has sparked massive excitement, her updated aesthetic has divided parts of the fandom. Viewers on Yahoo Entertainment and X have heavily criticized the styling of the short red wig used for the film, with some calling the look "messy". Conversely, many fans have defended the update, praising the decision to align her closer with her classic Marvel comic roots.
