Avengers: Doomsday & Secret Wars Rumor Roundup: Potential Spoilers Revealed As Another Plot Leak Surfaces

In our latest MCU rumor roundup, we have some potentially major spoilers for Avengers: Doomsday and Avengers: Secret Wars, revealing more about what to expect from the two-part Multiverse Saga finale.

Much to the disappointment of many fans, there was no Avengers: Doomsday trailer before showings of The Mandalorian and Grogu this weekend. Instead, it seems the teaser is being saved for July's San Diego Comic-Con.

For now, we continue to wait, but thanks to The Cosmic Circus, we have some big rumours to share both this December's Avengers movie and next year's Avengers: Secret Wars today.

Below, you'll find a full breakdown of all the biggest claims shared about both upcoming blockbusters, along with a newly surfaced Doomsday plot leak that may be the most accurate one yet. Be warned, however, that potential spoilers follow...

Avengers: Doomsday

  • Mister Fantastic and Shuri will share scenes in Avengers: Doomsday, though it seems multiple characters will attempt to explain what's happening to the Multiverse in their own way. 
  • According to this report, "Reed, Sue, Shuri, Beast, the TVA, and Monica have more of an explanation rooted in science. Thor and Loki have one rooted in magic. Steve has one rooted in experience. But Doom has one that incorporates all of them."

  • It sounds like we shouldn't spend too much time fretting about how the returning X-Men do or don't connect to the 20th Century Fox movies. As Perez puts it, "We're quite literally at the end of the Marvel Cinematic Universe, and most of the multiverse is dead except for a handful of universes because the laws of physics and stability are going haywire and out the window. Let the chaos fly."

  • After previously suggesting the Sacred Timeline is He Who Remains' interpretation of what reality should look like, Perez now posits that there are four canonical versions of the MCU. 
  • "The first one was the one we all knew up to Endgame prior to Loki, then the one after Loki (let’s just say it’s not coincidence that certain things have been popping up post Loki than don’t really make a lot of sense in the context of the MCU and leave it at that)," he teases, "then there’s the one we’ll get with Doom, and then the one after Doom."

  • Other Avengers: Doomsday tidbits include Magneto interacting with non-X-Men characters, Sting's "What Could Have Been" being relevant to Peggy Carter's story arc, and The Sentry having a close relationship with Yelena Belova and Gambit. Asked if we can expect permanent deaths, the scooper replied, "Yes... and then no."

  • Apparently, "There [are] at least 8-9 more [cast] that haven’t been confirmed yet that I know have filmed things on set."

Avengers: Secret Wars

  • When we reunite with many of Avengers: Doomsday's leads in Avengers: Secret Wars, they'll be "NPCs until their minds get unlocked." In terms of returning villains, "Anyone and everyone is fair game."

  • It appears characters currently residing in Valhalla will factor into the movie. As a reminder, that includes Odin, Heimdall, and perhaps the most likely possibility, the Mighty Thor (Jane Foster).

  • There will be room for characters in Secret Wars who were absent from Doomsday, but Perez saves the most intriguing, albeit frustratingly vague, hint for last. "Even though he’s not in either movie, He Who Remains won," the insider notes. "And we’ll leave it at that."

  • An Avengers: Doomsday plot leak has surfaced on Reddit, which, according to at least two prolific leakers, is mostly accurate for the pre-reshoots version of the movie.

He should come off as a force of nature at first. After seeing unbelievable destruction and feats of strength beyond human comprehension, then allow audiences to see glimpses of humanity inside the brute beast.

Exclusive only to the ticket-buying folks in attendance. Everyone NOT part of the audience will have to settle for a few shitty, shaky, poor-quality online iPhone recordings that will then be systematically snuffed-out by Disney. Nature of the beast I suppose. 🫤

The projects we got/will get after Loki and before Doomsday set within our main universe were & are Captain America:Brave New World ,Thunderbolts , Echo ,Agatha All Along , Daredevil Born Again S1 & S2 , Ironheart , Wonder Man & VisionQuest…

We had others like Deadpool & Wolverine aswell as FF but those were set in different universe and not what I would consider the MCU unless someone feels differently.

Regardless ,the only things out of those projects I can think of that don’t particularly make sense in the context of the MCU right now is unexplained powers emerging such as Simon in Wonder Man which makes me think of mutants so I wouldn’t be surprised if that’s it after which we get Battleworld most likely and then our soft rebooted MCU post SW where we fully dive into mutants & such hence is the insinuation that Loki or whoever unintentionally or intentionally messed with reality?.

Also I fully think the X-Men we see in Doomsday aren’t the Fox’s ones but just variants of those!!.

This all sounds like shit on a stick in my opinion which doesn't matter.

Marvel isn't that smart to write up a plot so confusing with these incursions. The GP would be lost in thought over and over again.

It'll end up being rotten.

Join the DC Alliance, the only alliance that matters.

He Who Remains basically established what would happen if Loki did what he did. He told him multiple times over and over again. And Loki chose free will and a Multiversal War.

Checking out that Reddit description, it sounds cool. Especially the beginning and the Avengers vs. X-men battle. I will say, though, we must get a Hulk vs. Wolverine fight with Jackman’s Logan in Secret Wars. Has to happen. Part of me feels like maybe they’re making him savage again in Spider-man: Brand New Day in part to set that up. Fingers crossed.
ElJefe
ElJefe - 5/25/2026, 7:26 PM
I wonder if they’re going to split Banner from the Hulk. It’s an easy way to make him savage an unrestrained- and they get Banner as a thinker and planner on the other side of the war.
TheVisionary25
TheVisionary25 - 5/25/2026, 8:30 PM
@ElJefe - that would be a good next direction for the character imo…

Banner is finally rid of the Hulk but realizes that perhaps them being together was better for the rest of the world etc.

I HATE THIS.

If Caps universe had to be purged then why didn't 828 need to be purged?
Why not just have 828 be the result of the newly created timeline? Oh that's right because then they couldn't do the radically reworked and sacrilegious Doom origin where he blames Cap for his disfigurement not Reed and also blames Cap and his family for the death of Doom's family (his wife and kid not his mom) and to be jealous of what Cap has and not jealous of what Reed has.
And of course they needed to have a reason for 828 to suffer an incursion right? Wrong! If incursions are happening then incursions are happening. You don't need a particular and specific reason for each and every one of them to happen. Would there be mutiversal exiles on every incursion earth? On the X-Men's Earth or in the main MCU? Are the FF on Earth 199999 the reason for the incursion? THIS WHOLE THING IS SO [frick]ED!!
Shoulda gone with The Beyonders.

Definitely shouldn't have had Doom be the actual antagonist. To the degree that he's the one who wants the Earths to collide in the first place!!! He's the reason the multiverse dies!!! This is the reverse of the comics. I know they changed Thanos' motivation and made it dumb (because he would need to do it every few decades because of population increase) and I know that it would have been a creative challenge to artistically express the poetry of Thanos as an existentially suicidal nihilist like he is in the comics. I get that and that movie worked out fine despite that (certainly not because of that).
But it wouldn't have been that hard to adapt the excellent and only slightly nuanced arc in the comics. Doom saved reality. His contingency plan succeeded where the heroes failed. Then this savior becomes corrupt due to his ego and THAT'S when he becomes the antagonist. In Secret Wars. Way more interesting. And I don't think it's at all too complicated for the GA. Not that that should even be a concern with a movie this crazy. You already lost the GA. This is a suicide mission. Don't worry about winning the GA back and getting the latest generation invested until the reboot. And boy should they reboot hard.

I knew they wouldn't have the nuance of the moral dilemma of the heroes. They hinted at it in DS-MOM but I knew that would be as far as they were gonna go. So they go straight to The Cabal. Except The Cabal are the X-Men. It would have been way cooler if it were the actual Cabal and they were working for Doom unbeknownst to the heroes. Miles Teller as The Maker, Julia Garner as Shalla Bal/Black Swan, Namor, Corvus Glaive, Proxima Midnight and Josh Brolin as Thanos. And we all know it would have been more impactful if he had ripped out Thanos' spine instead of Loki's.

And I'm not crazy about the residents of Battleworld being like "NPCs until their minds get unlocked". That just undermines the whole concept. It makes it lesser. Commit to the premise. This would also low key undermine the reboot if they had Battleworld just be a "False reality". It's the real reality. Tobey Maguire might be a Spider-Man in that reality but he's not a mindwashed Raimiverse denizen. He's a real person who exists on the reality of Battleworld. It's a new thing made out of pieces of old things, but those old things are reformed and remade. It worked in the comics on characters like Sue, Valeria and Franklin because they fell out of the ark. But I don't remember anybody else having memories of a previous version of themselves from the previous multiverse. Unless Doom's wiped my memory.

The lack of universes is disturbing. And they're all universes we've seen previously in The Multiverse Saga. That makes this even more disappointing than DS-MOM (which I'm starting to think was as good as we were ever gonna get). But maybe they have actually gone all out.

The lack of Beyonders is much more disturbing though and they could have tied up their Arishem thread there too, especially considering it is a movie called Doomsday (which literally means Judgment Day) and it's coming out in 2026 the year that Jack Kirby said would be the year of Arishem's judgment.

I hate to be a hater but I hate this. There is a lot in there that would give me multiple fangasms though; All the incursions, Hulk vs Thing, the potential Void variants, The cult of Rabum Alal, Sue pregnant again, the incursions and just all the toys playing together.

It's the fundamental plot that I hate, it's so wrong. It's really bad. I can see why Markus didn't wanna do it it now. They really dropped the ball with the main Doom/Cap story.
Seriously, yesterday my most anticipated cbms were:
1. Secret Wars.
2. Doomsday.
3. Beyond the Spiderverse.
4. BND.
5. The Batman part II.

But now I'm so disenchanted with the MCU it's:
1. Beyond the Spiderverse.
2. The Batman part II.
3. Maybe Clayface?

I just hate this. And I think it is on the level btw. And I hate it. Did I mention that? Hate. It.

But the internet has too many haters and my feelings on this are not at all positive, so maybe I should take a time out until BND releases. Or until He-Man maybe.

#FireGunn was right.
Reboot the MCU and the DCU, ffs.

Observerite out!

@ObserverIO - the universes facing incursions are all linked. You've got the 616(main mcu), 828(F4 universe), 10005(Fox X-men universe), 96283(Raimiverse). The incursion is happening to all these realities because each one has had someone crossover to one of the others. Cap left 616 for 828, Monica Rambeau accidentally crossed over to 10005, Tobey's Spiderman crossed into 616. Not to mention all the other universes Doctor Strange and America Chavez crossed over into. Basically each universe now has a breach connected to the others. The incursions aren't just simply happening, they're happening due to the breaches caused by multiversal travelers.

Suddenly bringing the beyonders into the mix would make zero sense to the already established narrative. The GA would have no idea who they are or what relevance they have without there being a previously established thread introducing them. Doom doesn't want all the earths to collide or intend to destroy the multiverse. His goal is to save the multiverse but like in the comics, the destruction is always an accidental consequence of trying to prevent a larger problem. Doom doesn't save reality, he fails to. The creation of battleworld is the unintended but only available optiopatchworked reality.
n for his and everyone else's survival. Also, just like in the comics, none of the heroes on battleworld remember who they are at first, so basically NPCs. Battleworld is a false reality, hence the reason the heroes have to create a new one, thus the mechanism for the MCU's reboot.

There's not a lack of universes. Obviously, the spotlight will be on the universes we've already seen and know. Those are the characters we've always been focusing on across all these movies. That's not to say that there won't be the feeling and understanding through context clues that way more universes have been impacted.

You wrote all of that based on absolutely zero supporting evidence.
ObserverIO
ObserverIO - 6/2/2026, 6:54 AM
@vadersdaddy - I have the same evidence as you. The above leaks.

So every single universe in the multiverse has been breached by multiversal travellers?! Come on. In the comics it was natural entropy. But the process was being intentionally sped up by the Beyonders (at the behest of the Celestials who wanted to remake the multiverse without the Earth).

You don't need to build up the Beyonders just like you don't need to build up Doom. You tell the story in that one movie. If that's the story of the movie then that's the place to tell the story.

"Also, just like in the comics, none of the heroes on battleworld remember who they are at first, so basically NPCs."

There's nothing to remember. They are new creations not brainwashed survivors.

I do hope you're right about there being more universes. But to say it has to be the universes we've already seen makes no sense. We hadn't seem Tobey or Andrew's Spider-Men in the MCU until we saw them in NWH. That's why it was so exciting, because we hadn't previously had that connection before then.
