Avengers: Doomsday Rumor: A Detailed Breakdown Of The Movie Has Leaked Online - Spoilers

We've seen a few supposed leaked plot breakdowns for Avengers: Doomsday at this stage, and while this latest one could also be fake, it certainly makes for an intriquing read...

There have been a number of rumored Avengers: Doomsday plot leaks over the past few months, but several insiders believe that the most recent one was largely accurate aside from a few inconsistencies. Now, a far more detailed breakdown of the movie has been shared on Reddit.

While this does read as if it could very well be legit, it's entirely possible that someone took the previous plot description and filled in the blanks with the various other rumors that have been circulating. That said, there are a few minor details (the Fantastic Four cartoon; Reed signing an autograph, etc) that usually wouldn't find their way into a fake breakdown that lead us to believe that this is the real deal.

Assuming this is accurate, be warned of major - and we do mean major - spoilers from this point on.

If you've read the other leak, you'll know the basic outline, but this breakdown is a lot more extensive. We'll let you have a read through it for yourselves, but here are a few points of interest:

Major deaths: Nightcrawler, Mystique, Loki, Bucky Barnes, and Steve Rogers' son, James.

The identities of Doom's Latverian Witches: Death, Clea and The Ancient One.

Namor and Sue Storm: Invisible Woman reportedly brokers a treaty between Wakanda and the Talocans, catching the Sub-Mariner's eye in the process (the attraction is said to be one-sided, however).

Hulk vs. The Thing: The long-awaited big-screen clash between Ben Grimm and a variant of the Green Goliath is said to take place in the third act.

The final battle: As previously reported, Doom emerges victorious after establishing Battleworld, with most of Earth's Mightiest Heroes either serving the villain after having their memories wiped, displaced in other timelines, or dead.

In the post-credits scene, we learn that Wolverine and Tobey Maguire's Spider-Man have survived the Incursions with their memories intact.

Avengers: Doomsday and Avengers: Secret Wars were hit with significant delays last year, 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

"Universes collide and the Multiverse Saga begins its final chapter in Marvel Studios’ Avengers: Doomsday. Beloved heroes from three distinct universes will be set on a deadly collision course and ultimately face an existential threat unlike anything they’ve ever encountered. This epic film will lay the foundation for the future of the Marvel Cinematic Universe."

Doomsday will star:

Paul Rudd as Ant-Man, Simu Liu as Shang-Chi, Tom Hiddleston as Loki, Lewis Pullman as Sentry, Florence Pugh as Yelena, Danny Ramirez as Falcon, Ian McKellen as Magneto, Sebastian Stan as Bucky, Winston Duke as M’Baku, Chris Hemsworth as Thor, Kelsey Grammer as Beast, James Marsden as Cyclops, Channing Tatum as Gambit, and Wyatt Russell as U.S. Agent

Along with Vanessa Kirby as Sue Storm, Rebecca Romijn as Mystique, Patrick Stewart as Professor X, Alan Cumming as Nightcrawler, Letitia Wright as Black Panther, Tenoch Huerta Mejia as Namor, Pedro Pascal as Reed Richards, Hannah John-Kamen as Ghost, Joseph Quinn as Johnny Storm, David Harbour as Red Guardian, Ebon Moss-Bachrach as The Thing, Anthony Mackie as Captain America, and, of course, Robert Downey Jr. as Doctor Doom.

@HashTagSwagg - Killing Steve’s son is even worse. That’s way too dark. Waaay to dark. Seriously, that’s going to really turn off a lot of casual fans and families. I really hope that’s a fake out

@abd00bie - “Snowflakes” because we think killing Steve and Peggy’s child is a stupid move and way too dark? Because that’s a pretty dumb ass take TBH

@Bucky74 - Not to mention it's a plot device that ruins Cap's ending in Endgame and simultaneously ruins Doom's origin in one fell swoop.
TheAstoundingMan

@Bucky74 - Is this some conservative pro-life thing? Because that's the vibe I'm getting.
Bucky74
Bucky74 - 7/31/2026, 9:51 AM
@ObserverIO - Exactly. Children should be precious to Doom. If anything kidnapping Steve’s kid makes more sense because he can then force him to work with him. After an act like that you lose the entire “I can see things from Dooms POV too” aspect. It will turn a LOT of fans both hardcore and casual off and lose families for repeat viewings
Bucky74
Bucky74 - 7/31/2026, 9:52 AM
@TheAstoundingMan - It’s a “Don”t kill children thing” you moron. Especially a child of the hero most care about most. Why, you have no problem with child killing?

This sound like total garbage if true.
Also, if that rumor about Doom killing Steve's infant son is actually legit, people are gonna be pissed.
That goes waaaay too far just for cheap shock value.
Bucky74
Bucky74 - 7/30/2026, 8:48 PM
@Feralwookiee - Just saw this. I said the same thing! It’s way overboard and will piss off hardcore and casual fans to the point where it will backfire. It’s horror movie dark and too far. The smartest thing they can do is make it a fake out but it doesn’t sound like it

@Feralwookiee - Yeah I don't think they can get away with murdering a baby character, even if he's just snapped into dust or magic sparkles so it's not a graphic thing. People would find it distasteful at best.

@Bucky74 - Weren't you all the same bunch that claimed the MCU was too kiddie and didn't have stakes because nobody died? Now it's too dark?
YonnyLayna
YonnyLayna - 7/30/2026, 10:08 PM
@SonOfAGif - Babies Are safe almost on everything except very dark dramas or very dark horror films
Bucky74
Bucky74 - 7/31/2026, 12:12 AM
@SonOfAGif - I never said that genius. Killing Steve and Peggy’s kid is totally incongruous with even the most dark takes in the MCU and will rightfully infuriate fans. Red Guardian and M’Baku are useless characters that can go and Bucky’s death accomplishes the same thing without child murder

@Feralwookiee - Not a baby…10-ish years old…But yeah, kid killing might be a bridge too far in the MCU, at least for most. Some other leaks say that the kid, when Battle World is created, is resurrected believing Doom to be his father. We’ll see…
DarkeyeZ
DarkeyeZ - 7/31/2026, 7:33 AM
@Feralwookiee - Do you think it's too far because Doom isn't actually evil? If that's your logic, I can agree. Unless killing the baby will save a whole Universe, then it's not evil.
It's kinda crazy that people will call a comic book villain evil, but say they went to far when the villain does something humans do in real life more than you would think. If you knew the real stats of white mothers in America that kill their babies, you would be sickened and would throw up if you saw the combined stat of all mothers.

Feralwookiee - 7/31/2026, 9:06 AM
@DarkeyeZ - I think it's "too far" for a bunch of reasons, but yes, one of those is that it's not in his character.
Doom is a villain and sometimes anti-villain, but he has honor and believes what he is doing is right and for the greater good. There's even times he's TEAMED UP with Reed and other heroes to fight larger threats.
Slaughtering a child is way outside of his moral code.
It is also too much for audiences in a pg-13 film that is essentially geared to kids.

As far as the real world stuff, I (mostly unfortunately) am financially stuck in a Blue State and work at a very liberal college, so I see and hear how much these women love them some abortions. I believe in many cases, it's a necessary evil, but every attempt should be made to avoid this from happening to begin with. Just my 2 cents.

Feralwookiee - 7/31/2026, 9:14 AM
@vegetaray - Where has it been reported is around 10 when Doom supposedly kills him? (Not jumping on you, I just haven't read that anywhere.)

All we've seen of Steve's son is him as a baby in that one teaser.
Either way, Doom killing a defenselesd kid is totally out of character and something he'd never do.
vegetaray
vegetaray - 7/31/2026, 10:19 AM
@Feralwookiee - Multiple leaks say that yes

The cliff notes are something like this…

Steve stays with Peggy in the past…

Pre Time-God Loki, who is an active TVA agent, finds out and in attempt to keep the couple from getting ~pruned~ offers to move them to the Fantastic 4 universe, to which they accept…

Steve and Peggy have a baby, while in F4’s universe, shortly thereafter…

Doom’s wife and daughter are killed. Some leaks say as a result of his own experiments, and others say as a result of an incursion beginning when Steve and Peggy arrive on that earth. There’s was even a leak that combined the two and said Doom was already working on multiversal experiments when an incursion happens…

Doomsday takes place roughly 10 years after these events, which would make Steve and Peggy’s son 10-ish by the time this happens

@Feralwookiee - Also, I have a feeling that the “All of you have lived stolen lives, and it’s time you give them back…” dialogue that Doom says in the Comic-Con footage, is him directly talking to Steve right before he kills his son. It seems to fit perfectly with that context.

@vegetaray - Ah, gotcha. Thank you for the info.
I still hate it though. Lol

I'm pretty tepid overall on this.

@Nonameforme - My question is this....since the FF knows what Doom looks like without the mask are they not going to tell the MCU world that Stark and Doom look just a like once they see something of Stark???
Nonameforme
Nonameforme - 7/30/2026, 11:38 PM
@SADFFLECK - why not bring back a wasted villain from the of the first 3 phases? I'd even settle for malekith the dark elf to come back as doom over rdj.

@jst5 - its a whole chekovs gun situation if they don't address it. Otherwise we're the only ones who know which is stupid. I would expect that level of stupid from a zack Snyder movie. Coughs in Martha.
