Avengers: Doomsday Plot Leak Explained - Everything We Just Learned About The Movie's Plot

With a legitimate Avengers: Doomsday plot leak supposedly doing the rounds, we're explaining everything you need to know about that and what it potentially reveals about the upcoming blockbuster.

If you've been on social media today, chances are you've seen people talking about an Avengers: Doomsday plot leak. It started with YouTuber John Campea confirming the legitimacy of at least one that's done the rounds online, and there are even claims that it's been available for months.

While absolutely nothing is confirmed—and likely won't be until we sit down to watch the movie this December—the leak Campea is referring to seems to be one we shared on the site months ago.

As well as seemingly being the source of many social media "scoops," this (mostly) lines up with what we've seen in official material and various footage leaks, all from after this plot breakdown first did the rounds. 

It's worth noting at this point that some big changes have reportedly been made during reshoots, including Loki's role. The "canon" idea may have also been tweaked, while there are also some characters and plot points missing. 

Back to the leaked footage, it pointed to Doctor Doom's villainous nature being revealed when he pits the downed Sentinels against the Avengers, X-Men, and Fantastic Four. In this leak, it doesn't happen until Steve and Thor realise that Victor Von Doom has attacked the TVA and killed Loki.

Perhaps the bigger issue is that elements of Avengers: Doomsday sound extremely similar to Avengers: Infinity War. Once again, the movie ends with the villain standing victorious, suggesting the Russo Brothers are sticking to what they know works with this one. 

Even if this isn't the real plot leak that Campea is referring to, major Avengers: Doomsday details are out there, and the floodgates may be about to open.

As always, stay tuned for the latest Avengers: Doomsday updates as we have them.

Killing Loki again sounds very been there, done that.

@HashTagSwagg - And killing Steve’s son also sounds way too dark and would ruin the tone of these films. There’s dark, and there’s killing an innocent child dark. Don’t get me wrong, I believe this leak, but I think that plot point is awful (unless it’s a truck and Doom wants all the children for Battleworld or something).

right. i have a tough time believing that to be true when there are other ways Loki can be used in just the SW 2015 version of the story.

So John had casting news, that was debunked. Now he's got the whole script leak. And if it's true it's terrible. So what the [frick] are we even doing here?

@bobevanz - I agree that it mostly sounds bad and it seems the Russo’s learned the wrong lessons from Infinity War (like, “hey, let’s just go dark and kill everyone “)

Killing Loki again,can't wait to see that again.

having read this leak before, i think elements of it are true but not the entire thing. just seems like there's a lot missing.

like, how did Doom gain access to the TVA or Loki in order to kill them?

why would Steve of all people put his trust in Doom who supposedly already has a checkered history with the F4 in their universe?

there's no real presence of all of the other characters and what they're doing.

nothing about Wakanda or Tolucan is mentioned.

@themawisdead -

& i just outright don't believe that the Russos and McFeely would not dig into the moral quandry of destroying worlds as presented in SW '15.

there's way too much dramatic meat on the bone to relegate it to just something the alt X-Men were doing and not have our heroes face the same dilemma.

Plot leak is absolutely terrible.

Hasn't this plot, or elements of it, been going around for a couple of years now ?

I want to know (or maybe I don't) where we see Doom is explained to be Tony Stark, or not. Given the casting and announcement, that has to mean something.

Imagine being the average Joe who watched literally none of shows or maybe only a few of the movies since endgame and all this crazy stuff is happening, it’s like “when did this happen”

Killing off Tobey's Spider Man at the order of Xavier, then everyone else. Sounds like a real crowd pleaser. It's just out of touch enough to be true.

Wolverine dies to start the movie? Awesome! Unfortunately he’ll be back for Secret Wars, I’m beyond ready for Jackman to move on from the role.

This entire Doom movie is interesting, but Secret Wars is what I’m excited for, as it will truly set us on the course moving beyond these movies.
