Magneto Joins the Fight in the MCU
Sir Ian McKellen returns as Erik Lehnsherr, also known as Magneto, in Avengers: Doomsday. This will be the character’s first official appearance in the Marvel Cinematic Universe, after being a major part of the original X-Men movies. Known for his incredible control over magnetism, Magneto’s powers and presence will bring a powerful edge to the growing threat in the multiverse.
This marks McKellen’s sixth time playing the role and the first since X-Men: Days of Future Past. His return opens up exciting possibilities, especially with his complicated relationship with Charles Xavier. The MCU could choose to lean into Magneto’s villainous past or explore a more nuanced portrayal that reflects his fight for mutant rights. Either way, fans are eager to see how he will interact with heroes like Captain America, Thor, and the Fantastic Four.
Nightcrawler Returns to the Big Screen
Alan Cumming reprises his role as the teleporting mutant Nightcrawler, also known as Kurt Wagner. He first portrayed the character in 2003’s X2, and now, after over two decades, he will join the MCU in Avengers: Doomsday. Nightcrawler is a deeply spiritual and kind-hearted hero whose unique powers make him a valuable asset in battle.
Fans can expect to see his iconic teleportation powers put to great use alongside Marvel’s biggest names. Cumming recently hinted at a scene involving a fight between Nightcrawler and Reed Richards, played by Pedro Pascal. That kind of clash suggests a visually striking and intense moment in the film.
Mystique Brings Her Powers and Deception to the MCU
Rebecca Romijn is back as Mystique, one of the most mysterious and complex characters from the X-Men series. Known for her ability to shapeshift and mimic voices, Mystique is both a deadly infiltrator and a fierce combatant.
This will be her fifth time portraying Mystique, and her first since a cameo in X-Men: First Class. In previous films, she walked the line between hero and villain, and her return in Avengers: Doomsday could bring more of that tension into the MCU. With her history of deception, especially after the events involving the Skrulls in recent Marvel projects, the Avengers will likely approach her with caution.
Cyclops Steps into the Leadership Role
James Marsden’s Cyclops will finally get another chance to shine in Avengers: Doomsday. The leader of the X-Men, Scott Summers is known for his tactical mind and his devastating optic blasts. Marsden previously appeared in the original X-Men trilogy and had a small role in Days of Future Past, but this film could allow him to explore a more complete version of the character.
Fans are hopeful that the MCU will finally give Cyclops the attention he deserves. He is often overshadowed in past films, but with Avengers: Doomsday bringing together the X-Men, Avengers, and Fantastic Four, his leadership and values could be a guiding force in the team’s efforts to stop Victor Von Doom.
Avengers: Doomsday Promises the Biggest Marvel Crossover Yet
With 27 actors expected to appear, Avengers: Doomsday is shaping up to be the largest Marvel film ever made. It will be the first time many legacy characters, like Magneto and Cyclops, officially join the MCU. They will team up with the likes of Captain Marvel, Sam Wilson’s Captain America, and the Fantastic Four to face a multiversal threat that could shake every known universe.
The film is scheduled to hit theaters on December 18, 2026. Fans are already buzzing about what this massive crossover could mean for the future of Marvel storytelling.
