The third teaser trailer for Avengers: Doomsday has leaked online, and it immediately places the spotlight firmly on the X-Men. Moreover, what it reveals suggests a dramatically altered reality for Marvel’s mutant heroes—one that completely flips expectations for the upcoming multiverse blockbuster.
Avengers: Doomsday X-Men Face a Darker Reality
Until now, fans assumed an Incursion would bring the Avengers and X-Men together. Initially, they expected the teams to clash before eventually joining forces against Doctor Doom. However, the leaked trailer suggests something far darker is at play.
The X-Men’s world appears completely devastated, resembling the bleak future seen in Days of Future Past. Meanwhile, the X-Mansion lies in ruins. In the midst of this chaos, Cyclops is surrounded by Sentinels and seems to be making a final stand. Then, he removes his visor and unleashes the full force of his optic blasts.
This suggests that many X-Men may already be dead. It could explain why several major mutant characters are missing from the movie. Instead of a full roster, the story likely focuses on a smaller surviving group. This group joins forces with the Avengers and the Fantastic Four.
Avengers: Doomsday X-Men and Doctor Doom’s Sinister Plan
Speculation is growing that the Sentinels are under Doctor Doom’s control. This would make him the mastermind behind the X-Men’s world collapse. The footage likely takes place early in the film. It sets the stage for Professor X and Magneto to unite and lead a last-resort resistance.
This would explain the confirmed X-Men lineup, which reportedly includes Professor X, Magneto, Cyclops, Mystique, Gambit, Nightcrawler, and Beast, while characters like Jean Grey, Storm, Rogue, and Iceman are absent.
Cyclops’ Comic-Accurate Costume
One standout moment from the teaser is Cyclops’ suit, inspired by Jim Lee’s iconic design. While the yellow trunks are removed, the costume remains a faithful adaptation, delighting fans who have long awaited this version on screen.
Multiverse Complexity
With Doom-controlled Sentinels, confirmation that the X-Men’s Earth is separate from Deadpool and Wolverine’s reality, and Monica Rambeau expected to bridge worlds, the story’s scope appears far more complex than initially believed. The trailer sets the stage for an epic, multiverse-spanning showdown.
Upcoming Avengers: Doomsday Trailer Focuses on X-Men
The next trailer for AVENGERS: DOOMSDAY will release in theaters on January 1 and will focus on the X-Men. Fans are eagerly anticipating new glimpses of the mutant team and how they’ll interact with the Avengers. Speculation is already growing about possible surprises and connections to the larger multiverse storyline.
Avengers: Doomsday is set to release on December 18, 2026, followed by Avengers: Secret Wars on December 17, 2027. The events teased in the trailer may serve as crucial setup for the epic showdown in Secret Wars, where multiple realities collide and fan-favorite characters could face life-or-death stakes.
By connecting the X-Men’s devastated world to the larger multiverse narrative, Marvel appears ready to deliver one of the most ambitious crossover events in cinematic history. The trailer gives fans just enough to speculate while keeping major plot details under wraps.
