AVENGERS: DOOMSDAY Teaser Leak Delivers a Comic-Accurate Cyclops and a Dark X-Men Future
The third teaser trailer for Avengers: Doomsday has been released in theaters and has leaked online, and it’s sending Marvel fans into overdrive. This is a brief but loaded preview that leans hard into X-Men mythology, teasing a grim future and the most faithful live-action Cyclops we’ve seen yet.
The teaser opens in a haunting location, as the broken remains of the X-Mansion fill the screen, with the “Xavier’s School for Gifted Youngsters” sign lying in ruins.
From there, the tone slows down as we find Professor X (Patrick Stewart) and Magneto (Ian McKellen) seated across from one another, locked in a quiet game of chess. It’s a familiar image, but the setting makes it feel heavier, like this might be the last time these two old friends sit together.
Charles Xavier is shown in his classic X wheelchair, the same design fans will remember from the original X-Men films. Magneto appears older, sporting long hair and a beard, and the moment culminates with the two men placing their hands together in a brotherly gesture that carries decades of shared history.
Magneto’s voice cuts through the teaser with a chilling line that frames everything that follows:
"Death comes for us all, that’s all I know for sure. The question isn’t are you prepared to die, the question is who would you be when you close your eyes?"
From there, the teaser jumps to complete devastation. A battered Cyclops (James Marsden) stands alone on a battlefield, bloodied but unbroken. He removes his visor and lets his optic blasts rip into the sky, and it a pretty striking visual.
In the background, a towering Sentinel moves through the wreckage, strongly suggesting that Scott Summers may be the last mutant left alive here. His suit looks also looks like it was ripped straight from the comics, finally giving fans the Cyclops they’ve been waiting to see on the big screen.
The teaser closes with… “The X-Men Will Return In Avengers: Doomsday,” followed by a countdown clock ticking toward the film’s release next December.
The film is directed by Anthony Russo and Joe Russo, working from a screenplay by Stephen McFeely, their longtime collaborator from the Avengers and Captain America films. Michael Waldron, who previously worked on Loki and Doctor Strange in the Multiverse of Madness, is also involved with the script.
Avengers: Doomsday is scheduled to hit theaters on December 18, 2026, with Avengers: Secret Wars set to follow on December 17, 2027.
