AVENGERS: DOOMSDAY's Third Teaser Trailer Leaks Online And Shows Comic-Accurate Cyclops Battling [SPOILER]

"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?" - Magneto, Avengers: Doomsday

The third Avengers: Doomsday teaser trailer has now leaked in its entirety, and if you had any doubts about what the Russo Brothers are cooking up, this should help ease your mind.

Taking us into what appears to be the ruins of the X-Mansion, the classic "Xavier's School for Gifted Youngsters" sign is shown amid the rubble, before we find Professor X and Magneto in the middle of a game of chess.

The two old friends place their hands together in a brotherly gesture, and we see Charles Xavier in his classic "X" wheelchair (like the one in the original X-Men movies, not Doctor Strange in the Multiverse of Madness). Magneto, meanwhile, appears to have long hair and a beard.

We're then taken to a battlefield, where a bloodied Cyclops removes his visor and allows his optic blasts to shoot into the sky. A Sentinel can be seen walking in the background, hinting that Scott Summers is the last mutant left standing. 

The teaser ends with, "The X-Men Will Return In Avengers: Doomsday," and another countdown to the movie's release next December.

Between the nostalgia, Cyclops' comic-accurate costume, and the presence of Sentinels, all signs point to the Russo Brothers giving fans exactly what they want from this movie. As for where these scenes fit into Avengers: Doomsday, that's up for debate, but all does not appear well in the X-Men's reality. 

Watch the latest Avengers: Doomsday teaser trailer in the players below. 

[REMOVED AT THE REQUEST OF THE STUDIO]

Avengers: Doomsday officially stars Chris Hemsworth, Anthony Mackie, Winston Duke, Tom Hiddleston, Sebastian Stan, Letitia Wright, Paul Rudd, and Robert Downey Jr. Wyatt Russell, Simu Liu, Tenoch Huerta Mejia, Florence Pugh, Danny Ramirez, David Harbour, Hannah John-Kamen, and Lewis Pullman all make their Avengers franchise debuts in the movie.

The Fantastic Four: First Steps leads Pedro Pascal, Vanessa Kirby, Ebon Moss-Bachrach, and Joseph Quinn join them, as do X-Men franchise stars Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, James Marsden, with Deadpool & Wolverine star Channing Tatum.

Chris Evans is also officially confirmed to reprise his role as Steve Rogers, as is India Rose Hemsworth as Love. The Hollywood trades have reported that Hayley Atwell and Ryan Reynolds will appear as Peggy Carter and Deadpool, respectively.

The Russo Brothers direct Avengers: Doomsday from a screenplay by Stephen McFeely, with whom they previously collaborated on the Avengers and Captain America franchises. Loki and Doctor Strange in the Multiverse of Madness's Michael Waldron is also working on the script.

Avengers: Doomsday is set to be released on December 18, 2026, with Avengers: Secret Wars scheduled to arrive on December 17, 2027.

@JoshWilding - nice! I watched DOFP last night too, great movie still. And before that Ironman, just because I wanted to remind myself what a good movie Marvel can make. Ironman for me ticks all the boxes, introduces a character, plenty of supporting characters like Pepper, great sound track, amazing detail of the suit evolving and seeing it going on and off. Loads of action. It’s difficult to fault really and watched now it exposes the current releases for what they are. Lazy, poorly written and tainted by a self destructive need to comply with Disney D&I rules at the expense of the source material.

@JoshWilding - bout time they gave Cyclops some time to shine, but I got a feeling his time to shine is when he will die.

@Spike101 - You nailed it. Disney literally killed their cash cow. With the exception of NWH (yes, the nostalgia bait worked on me and I loved that movie) and the incredible stupid fun of Deadpool and Wolverine (I also loved it), and maybe Guardians 3, everything I else has been borderline unwatchable

This leak is still up after two hours and people don't think these leaks are Disney's doing haha. I'll wait for the official. Saw Fire and Ash yesterday hoping to see this. Saw the lame Thor one which nobody in the packed theater made a peep. Also Avatar 3 is the best one of the bunch and if you don't see it in Dolby 3D HFR you're a clown

@bobevanz - this is my line of thinking too. Leaks are guerilla marketing these days. The fact they aren't ripped down as soon as they go up says everything.

Spike101 - 12/28/2025, 12:00 PM
@Bucky74 - I entirely agree, if you look right back to the beginning of the MCU the tone was more serious with a nod to the comicbooks, now they are built around the Disney make a movie checklist. Aside from the odd exceptions like Infinity War the rot actually began to creep in with the first Antman movie and it’s annoying comedy characters like Luis. And Luis was only the tip of the Disney iceberg too, later movies are sprinkled with characters like him, think of the annoying girl in Shang-Chi for example who ruined every fight scene with a cringy joke. The Eternal with his own publicist, I’m not sure that was plucked from the comics. We’ve had save the children, the children save everyone else, every movie has to have kids in it now. Basically all Disney using Marvel’s characters to sell their own version of reality.

@Matchesz - I thought maybe they'd do the de-aging thing here. A nearly 100 year old man playing Magneto is kind of ridiculous.

@Ryguy88 - thats part of what makes professor x and magneto epic they’re frail old men but just needs to think a thought or twist a finger and ur a vegetable

I'm starting to wonder if the X Men all get wiped out fairly early on in order to establish both the stakes and Dooms power level.

@IronDean2099 - probably some of them will be, i'm fact i believe the ones who will survive are the ones showed in the cast announce, the rest will appear only to die
bkmeijer1
bkmeijer1 - 12/28/2025, 7:16 AM
@IronDean2099 - I'm guessing the "honor" of getting killed off early goes to the Council of Kangs. They're set up as a big threat, so Doom wiping them out in one fell swoop immediately establishes him as a major threat

Conquistador - 12/28/2025, 7:45 AM
@IronDean2099 - as sp0ck rightly said in the last thread, they're likely going the Infinity War route.

These x-men variant are going to be introduced as the centre and quickly liked due to the nostalgia, but then all or most get wiped out by the end of the movie giving way to the other characters for Secret Wars to take centre and 'avenge' those variants. Probably won't bring them back, but id imagine they get a reset and the MCU 616 merge creating the new sacred singular(?) Timeless where we get the new Xmen and maybe recast legacy characters.

@Matchesz - The sad thing is we'll very likely only get the X-Men right in this movie. I wouldnt hold my breath for this in the reboot.
Matchesz
Matchesz - 12/28/2025, 7:50 AM
@CorndogBurglar -True but they cant be worst than the sequels after DOFP, just wish we could’ve stuck with the OG crew after that ending so we can get more of everyone. The Cyclops recast was hella weak and didnt look like James Marsden

@Matchesz - Too be honest those "prequel" movies never sat right with me for a lot of reasons. DOFP was a great movie, but First Class, Apocalypse, and Dark Phoenix were all terrible movies.

They contradicted so much. First Class didn't know what it wanted to be. A prequel or a reboot? It kept some things from the OG movies, but contradicted others.

DOFP changed history because of the cluster that First Class was.

And their biggest mistake with thise movies was setting each film in a different decade. Like, by the time Dark Phoenix came out the X-Men should have been like 50 years old lol.

But I agree. I always missed the OG cast and would have much preferred a continuation of those movies over the prequels we got.
Matchesz
Matchesz - 12/28/2025, 8:17 AM
@CorndogBurglar - yeah those are good points First Class to me was okay in the theatre but lots of things made it overrated to me too, apoc & phoenix were massive missteps and waste of film. J lawrence is a cool person but her star power fcked those scripts up

@CorndogBurglar - The X-Men prequels were pure chaos. The entire franchise is better if you just ignore them.
