Ever since that massive Avengers: Doomsday cast announcement, fans have been wondering about the inclusion of so many characters from 20th Century Fox's X-Men movies. Will the mutants join Earth's Mightiest Heroes in the battle against Doctor Doom and his forces, or will we see an Avengers vs. X-Men-inspired situation unfold?

Recent rumors have pointed to the latter, but we haven't actually seen any evidence that the Avengers will clash with the X-Men yet. All photos from the set have confirmed is that the X-Mansion will come under siege from Sentinels at some point in the movie.

Now, Daniel Richtman claims to have confirmed a report from an unvetted source (might be worth keeping an eye on from now on, though) that Robert Downey Jr.'s Victor Von Doom will "use the Sentinels to attack the X-Men."

If accurate, this would suggest that the Children of the Atom will side with the Avengers in this fight... unless they believe the Avengers were responsible for the attack!

There's been some speculation that Doom will enlist "evil" variants of Tony Stark's former teammates to pose as the actual 616 Avengers and wreak havoc throughout the Multiverse. It's an intriguing theory, and may now have some more weight behind it.

Josh from Den of Nerds weighed in on RPK's report with the following.

In related news (well, rumor), MTTSH is claiming to have confirmed that Ryan Reynolds will indeed be back as Deadpool for Doomsday. The Merc With a Mouth wasn't part of the first cast reveal, but we do know that another is imminent.

Avengers: Doomsday and Avengers: Secret Wars were recently hit with significant delays, with Doomsday now set to arrive in theaters on December 18, 2026, and Secret Wars positioned for December 17, 2027.

Both movies will be directed by the Russo brothers, who also make their MCU return after helming Captain America: The Winter Soldier, Captain America: Civil War, Avengers: Infinity War and Avengers: Endgame. 

"Being able to create stories and explore characters within the Marvel Universe fulfilled a life-long dream of ours, and we discovered a powerful connection with audiences in each film that we made. We’re thrilled to collaborate once again with Kevin, Lou and the entire Marvel team to bring this epic adventure in storytelling to new and surprising places for both the fans and ourselves”, said The Russos in a statement after the SDCC panel.

@Feralwookiee - I really don’t like that these films now resemble those dumb Twitter posts like “What If Tony Stark Was Thanos???” Or whatever dumb shit they post, moreso than any actual comic book. I knew we were [frick]ed when they did the three Spider-Men teaming up. It’s a movie inspired by Instagram posts

@Asterisk - Agreed.
It's a cheap and lazy gimmick imo and it's worn out it's welcome.
I'm tired of variants and the multiverse, but they've gotta keep beating a dead horse. 😑

Interesting….

I wondered why he wouldn’t use Doombots to attack them unless he wants to remain hidden hence using the Sentinels instead so he can manipulate that universe’s X-Men to go after the Avengers especially if he makes them think they sent those from another universe.

I do love me a master manipulator which fits Doom so I hope we see that.

@TheVisionary25 - what if those Emergency Aid Ultronbots from Avengers:AOU were repurposed into Doombots or were a precursor to Doomsday?

@WruceBayne - I doubt it…

Think they might just be seperate

This is manufactured speculation, that's all. Also he'd use doom bots, if he ACTUALLY WAS DOOM

As of writing, i dont think there is a rumor about this movie that has actually panned out.

And the important news of the delays didnt even get into those idiot scoopers' radars.

This will be so bad im excited to see how bad it will be. The Russos are hack and their careers were only lifted by cbm hype back then and fanboy sentiment.

@vectorsigma - Keep telling yourself that regardless of how Doomsday &/or Secret Wars turn out.

They delivered 4 bangers, even if Endgame has it's flaws & annoyances.

Winter Soldier is STILL THEE BEST MCU movie/work of the 36 films so far. Best Cap movie & the Russo's best work.

But sure, only a Hack(s) would deliver 4/4 bangers or an incredibly good Cap movie.

@TMW1987ProudProWrestlingFan - their filmography where they are directors are rotten 5/9. And their latest is 14%.

They are only good during the heydays of cbm. They rode the hype created by Whedon with Avengers 1.

With the poor performance of phases 4 and 5 and the new characters not resonating at all with the general audience, it will be hard for them to be lucky this time.

@vectorsigma - True. But whilst their filmography outside of the CBM infrastructure hasn't been great their work within that realm/the superhero genre has been rather stellar, can't deny that fact or deny all 4 of their MCU entries range from good (Endgame) to great (Winter Soldier, Civil War & Infinity War).

It seems their work comes out better when they're reigned in or over seen as opposed to what they do outside of Marvel, so as long as the same structure is in place on Doomsday & Secret Wars as their previous 4 entries, I think they'll do just fine.

This is a chance for McFeely to better write & The Russo's to direct better outcomes for those phase 4 & 5 characters that aren't resonating. I would have preferred Markus being involved again too, but I'm hopeful they can do things for the likes of Sam that Onah, Edwards & Spellman weren't able to do unfortunately.

And yes, I do know it could be hit or miss, people seem to love Infinty War Thor as the best portrayal/character take from this team & what they got out of Hemsworth, but I realise they also gave us Fat Thor & neutered Hulk. When they get it right, they nail it, when they get it wrong, it's unfortunate.

I'm hoping they get/do right by Sam & how everything is executed. Time will tell.

It’s like Marvel is going out of their way to purposefully overcomplicate their movies these days…

“Let’s make a Thunderbolts movie but it won’t actually feature any of the original Thunderbolts and in fact won’t even really be a Thunderbolts movie. Then after it’s been out for two weeks we’ll rename it the New Avengers.

Then let’s make a Fantastic Four movie but it won’t take place in the actual 616 MCU and will feature Franklin, Galactus and the Silver Surfer but it won’t be the actual real Silver Surfer.

Then let’s make a movie that introduces Doom into the MCU but it won’t be the actual 616’s Doom and will instead be played by the most popular actor in the entire MCU who spent a decade playing pretty much the most popular character in the entire series….And let’s also introduce the X-Men and possibly adapt the X-men V Avengers storyline but instead of using the 616 X-men we’re going to use versions from a completely different franchise who are played by actors who are all in their 80’s,60’s, 50’s and late 40’s.”

@BruceWayng - great point.

what's funny for me is the "marvel can do no wrong" crowd being blatantly treated as sheep with all these lousy decisions and continues to blindly defend it.

@BruceWayng - Yes, because all we need from a movie is a good old, simple, predictable story: one that starts with a hero-villain conflict and ends with the hero effortlessly killing the villain, despite a lot of destruction for no clear reason. The good old triumph over evil but with a new coat of paint.

They need Reynolds, Jackman, Holland and maybe Evans or this movie is DOA.

this is going to be a real "how can they make it work" thing on so many levels. how are they going to have Deadpool in it for example as a side character without the 4th wall breaks? assuming they will just have him talking to himself rather than to the camera with other characters just thinking hes broken?
SpiderParker
SpiderParker - 6/4/2025, 3:50 AM
@DemonTweeks - It's could work really well. Deadpool breaking 4th wall to make fun of his team-mates while they are making fun of him in-universe for losing his marbles. Until Watcher comes along and its revealed he could see him all along and was making comments to him (atleast some of them).
ObserverIO
ObserverIO - 6/4/2025, 4:39 AM
@DemonTweeks - In a movie with so many characters it'd be hard to even find time for a 4th wall break moment. Plus he's not the main character, he's not our host on this journey, so it's possible that he never once breaks the 4th wall.

Maybe some of his jokes are jokes that we (the audience) are in on that the other characters in the movie might not get, so he's vaguely breaking the 4th wall without actually looking at the camera.
Fogs
Fogs - 6/4/2025, 5:04 AM
@DemonTweeks - That's the easiest part imo. Just like it happens in any movie, cartoon or comic. He breaks it alone, the others don't have a clue of what he's doing or talking about.
Asterisk
Asterisk - 6/4/2025, 2:22 PM
@SpiderParker - I feel personally it would be more fun if they depicted his fourth wall breaking as actual insanity. Like he’s still doing it but now that he’s not the main character he’s like looking into an imaginary camera and talking about the “movie” he’s in where HES the main character. Like in his mind the movie is “Deadpool Meets The Avengers”
SpiderParker
SpiderParker - 6/4/2025, 2:55 PM
@Asterisk - That's a good idea.

Just a thought: He could even make a joke about how there used to be a asterisk as a placeholder for something like Deadpool v Doomsday: Dawn of Avenging but was removed when Gunn asked Feige to 'bury it' in exchange for GOTG4 ideas.

Man, I wish I had more faith in this. Could be epic but also a trainwreck given the current MCU state.
