Avengers: Doomsday Rumor Reveals Final Act Cameos, Second Post-Credits Scene, And A Big Twist - Spoilers

While we'd recommend taking this latest leak with a pinch of salt, a supposed Avengers: Doomsday plot breakdown reveals some big cameos, a shocking death, and both post-credits scenes.

As Avengers: Doomsday nears, more potential details about what fans can expect from the movie are circulating on social media. As always, whether they're real or fake will be determined this December, but there's often some truth to these leaks. 

Another possible plot breakdown is receiving a lot of attention on social media today, as it reveals several new details about Avengers: Doomsday's final act, a major character death, and even the post-credits scenes.

It's said that the climactic battle takes place in Latveria, with the Multiverse's Mightiest Heroes assembling to battle Doctor Doom's army of Doombots. Deadpool reportedly shows up with a team that includes Tom Holland's Spider-Man and Captain Marvel, only for Doom to unleash his own allies, including a Hulk Variant who squares off with The Thing.

While Avengers: Doomsday concludes with the end of the Multiverse, there is a huge death prior to that: Bucky Barnes, who Doom kills in cold blood. 

The movie will also tease what to expect from Battleworld, with Sue Storm, Franklin Richards, and Valeria Richards now Victor Von Doom's family.

Namor, the Thor Corps, and Steve Rogers—transformed into "Captain HYDRA" by Doom—will all serve the villain, who sits on his throne while looking out at the remains of Avengers Tower and the Baxter Building (lending some weight to theories that The Void could be tied to the new world Doom creates). 

As for Avengers: Doomsday's post-credits scenes, one reveals that Wolverine and Tobey Maguire's Spider-Man are still alive with their pre-Battleworld memories intact. The other features the Scarlet Witch, who reportedly appears alongside "other heroes." 

It also sounds like Elizabeth Olsen is on her way to the UK for Avengers: Secret Wars...

In Avengers: Doomsday, beloved heroes from three distinct universes will be set on a deadly collision course and face an existential threat unlike anything they’ve ever encountered.

Avengers: Doomsday stars Chris Evans, 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, Mabel Cadena, Florence Pugh, Danny Ramirez, David Harbour, Hannah John-Kamen, Lewis Pullman, India Rose Hemsworth, and Wesley Holloway all make their Avengers franchise debuts.

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

The Russo Brothers direct Avengers: Doomsday and Avengers: Secret Wars from a screenplay by Stephen McFeely, Chris McKenna and Erik Sommers, and Michael Waldron. Kevin Feige, Louis D'Esposito, and Jonathan Schwartz produce the movie, with Callum McDougall serving as executive producer.

Avengers: Doomsday arrives in theaters on December 18.

@WhatIfRickJames - if rumors are true, we’re also about to see Loki die for the fourth time. And if Professor X dies, as it seems most everyone is about to be killed, it’ll be the fifth time for him.

@WhatIfRickJames - Even better, he's killed by RDJ who then says "that's for killing my mom and dad"! 🤣

@tvor03 -

What was the fourth time?

I remember him being "killed" by Jean Grey (Famke version, X-men 3), X-24 (Logan), and Wanda (well,...and alternate version of him in Dr. Strange 2).

I don't seem to remember him being explictly killed in Days of Future Past (The dark future), although it was heavily implied that that was their fate. But since that timeline was reset by the events of Logan's actions in the past, I don't necessarily count any of those deaths are real or sticking, and besides which, he's alive at the end of the movie.

I'm still optimistic about this movie, but I am not at all excited about the "evil versions of familiar heroes" if that ends up being true. Lazy & dumb

It's all stemming from a place of utter hatred and contempt for the audience. The idea is they want the actors tied to characters you love to be brought back, belittled, vilified and then defeated by the new characters that nobody actually connected to in order to double down on the slop from Phase 4, 5 and 6.

I like how Paul rudd's Ant-Man permanently dies in Avengers: Doomsday, but nobody gives a single frick about his character after Ant-Man 3: Quantumania so none of the leakers are even bothering to mention it.

It's also worth noting all the Captain America stuff is because the writers hate the audience. It comes from the following mentality:

• You didn't like Sam Wilson Captain America and wanted it to go to Bucky instead, Steve's oldest friend who we set-up in Winter Soldier and Civil War to take up the mantle? Well frick you we're going to kill off Bucky Barnes and pretend its to unite the heroes when the heroes already have enough reasons to unite.

• You hated the nonsense ending we gave Steve Rodgers in Endgame? Well frick you he's going to have his son murdered in-front of him and he's responsible for the end of the multiverse because he's a selfish prick, lets have the entire movie be about mocking, insulting and belittling him and then ripping away everything he loves.

• We need to bring back previous actors so that people will watch our movie? Well frick you, here is Chris Evans back but he's not going to suit up in Avengers: Doomsday and when he eventually does suit up it's going to be as Captain Hydra one of the most disliked plot elements in history that we parodied in Endgame.

@Scarilian - At this point, if they wrote Steve Rogers out of Doomsday entirely it would actually be a kindness.

Yeah, it feels like they are personally angry at the fans for not liking his ending in Endgame so now they intend to destroy the character.

I hope most of this isn’t true.

Killing Bucky to cement bland FalCap in place is a terrible decision. But agenda over quality entertainment is what Hollywood is all about now.

I feel like this sounds more like fan fiction (for the most part) then other leaks…

Also why would this Victor who seems to have had a cordial relationship with Reed & The FF before as Sue said in the last trailer , he lost everything take on the formers family as his own in Battleworld when he could perhaps just “resurrect” his own or take them from a reality where they are still alive?.

I get that it would be “comic accurate” but there it made sense too given Victor has a long standing grudge & rivalry against Reed for a long time but in this take it seems like again as Sue states , he was a decent person who is implied to have had a good relationship with the team before he lost his family and was presumably left disfigured/scared from the same situation which made him reclusive and broken until he comes back into their lives with some mysterious agenda in Doomsday so I don’t think him making Sue into his wife for example would work here given he doesn’t have any real animosity towards Reed unless we find out he was unintentionally involved somehow in the incident that made Victor lose everything and he blames Reed to some degree.

However I could see Namor serving Doom given we see them turn their weapons on Shuri and others in the trailer since he may have promised them a place in his new world and they feel he’s the only way they can be saved!!.

"Wolverine and Tobey Maguire's Spider-Man are still alive with their pre-Battleworld memories intact."

That's stupid AF. I hate that. If they died then the Battleworld versions of them should be all new. That's so [frick]ing dumb I can't even.

I really hope this isn't the route they're going.

death has no meaning in the MCU. You die, you get resurrected, or alternate you walks out of another timeline or universe. I have an idea, let's KILL EVERYONE at the beginning of Doomsday and then have a blank screen for 2 hours. THAT WOULD BE RADICAL
