- Marvel has released the third teaser for Avengers: Doomsday
- It focuses on the X-Men and hints at some mutant versus sentinel action
- The MCU film's fourth teaser has also leaked online
The third teaser for Avengers: Doomsday has officially hit the internet – and, surprising no one, it focuses on the X-Men.
One week after the mutant-fronted teaser leaked online, Marvel has uploaded a higher quality version of said footage to its YouTube channel and various social media accounts.
Just like Doomsday's previous teasers, the X-Men preview video provides little information about the highly anticipated Marvel Phase 6 movie's plot. However, it suggests there'll be some mutant mayhem – potentially of a lethal variety – to behold, with James Marsden's Cyclops unleashing a powerful optic blast while screaming in anguish as a mutant-killing Sentinel looms behind him.
Will that scene of desolation follow the Professor X and Magneto one that's also spotlighted in the teaser? I suspect it will. Judging by the ominous voiceover from Magneto that accompanies the footage, it's possible that some or all of the returning X-Men actors, who were announced as part of Doomsday's initial 27-strong cast, might not make it to the end credits. I wonder what odds I can get on Patrick Stewart's Professor X dying on-screen again...
How many Avengers: Doomsday trailers will be released?
Nobody knows for certain but, depending on what's been bandied around some online communities, there could be up to six (!) teasers before the next Avengers movie's first full trailer is released.
When Avengers: Doomsday's first teaser leaked online last December, rumors circulated that three teasers – the first confirming Steve Rogers' return in Avengers: Doomsday, the second starring Thor, and the last featuring Doctor Doom – would precede Avengers 5's inaugural trailer. Each teaser would run ahead of public screenings of Avatar: Fire and Ash for one weekly only before landing online, and lead up to the release of Doomsday's official trailer in mid-January.
However, over the 2025 festive break, fresh details emerged that there would be four teasers for the Marvel Cinematic Universe (MCU) flick.
Predictably, the fourth one has already leaked online. I won't be sharing screenshots of said teaser or links to the leaked footage, but I can say that, as prominent insider MyTimetoShineHello correctly revealed ahead of time, it features Shuri, M'Baku and Namor from the Black Panther film series, plus Ben Grimm from The Fantastic Four: First Steps.
This teaser won't be the last one we see. Indeed, two more trailers were recently approved by the Korean ratings classification board – i.e. the same place that details about Doomsday's other teasers first emerged. The reportedly 65-second and 72-second long teasers were certified on December 30, 2025 and January 2, 2026, which implies they'll run ahead of Avatar 3 throughout January.
For what it's worth, another leaker in Cryptic4KQual has claimed their sources only informed them about four teasers before speculating that a fifth one could be the first full trailer. Considering the Korean ratings classification board has approved licenses for six Doomsday teasers, though, I believe we'll be treated to more teasers very soon.
As for who might appear in them, other major MCU characters and supergroups – Sam Wilson/Cap 2.0 and his Avengers team, Loki, Thunderbolts/The New Avengers, the rest of The Fantastic Four, and even Doom himself – haven't featured in trailers thus far. It would be a huge oversight if Marvel didn't highlight those heroes and the Multiverse Saga's new primary villain, wouldn't it?
One final thought before I wrap up this article: If three more teasers follow the X-Men one and if Marvel maintains the weekly release strategy it's employed so far, the sixth and final preview video could drop on January 27. That's just 12 days before the Super Bowl, an annual sports event watched by billions that, in the eyes of the world's biggest movie studios, is the perfect place to debut trailers for the year's hottest new movies.
What are the chances, then, that Marvel releases six teasers across a six-week period leading up to the unveiling of Doomsday's first official trailer during one of the 2026 Super Bowl's ad breaks? Pretty high, in my view. I guess we'll see if I'm right in the weeks ahead.
