Best Avengers: Doomsday Theories (October 2025)

by

Avengers: Doomsday is definitely the MCU film fans are most excited about right now. This is largely because the movie is expected to deliver a huge, impressive story, fitting for the amazing group of heroes who are set to appear in it.

The core of many ideas about Avengers: Doomsday revolves around a specific story. Understandably, Marvel Studios has been very careful to keep the film’s actual plot under wraps. They managed to conceal some potential spoilers, like Benedict Cumberbatch returning as Doctor Strange, until the actors themselves revealed their roles. Other questions remain, for example, exactly which character Chris Evans will portray.

Best Avengers: Doomsday Theories as of September 2025

When deciding on the most interesting Avengers: Doomsday theories, we looked for both originality and how believable they were. For example, although it’s possible that Chris Evans might portray the villainous Captain America from the Secret Empire storyline, it doesn’t seem very probable. We also decided to skip theories that were just too predictable to be considered real theories. The most obvious one – that the film’s plot will directly follow the 2015 Secret Wars comic event – was avoided simply because the next movie is titled Avengers: Secret Wars.

Doctor Doom is a Tony Stark variant

The announcement that Robert Downey Jr. would reprise his role in the MCU, but as Doctor Doom, sparked considerable backlash from fans. Although he’s a talented actor, he’s become strongly associated with his portrayal of Iron Man. Many worried that even with a mask concealing his features, it would be difficult to see him as anyone other than Tony Stark. This led to speculation that the Doctor Doom appearing in Avengers: Doomsday is actually a version of Tony Stark from an alternate universe.

The concept of someone *other* than Victor Von Doom being Doctor Doom isn’t new. The comics have featured several plots where a hero temporarily took on the Doctor Doom persona. For example, in the current Ultimate Universe, Doctor Doom is actually Reed Richards of that world. There have also been What If? stories exploring scenarios where Doctor Doom and Tony Stark swapped bodies and lived each other’s lives. This history might be why the MCU’s version of Doctor Doom shares so many similarities with Tony Stark. It’s a recurring theme!

As plausible as this theory is, however, it has already been debunked.

In a conversation with Business Standard, Robert Downey Jr. shared how Kevin Feige convinced him to join Avengers: Doomsday. Feige essentially walked him through the comic book origin story of Doctor Doom, explaining the true nature of Victor Von Doom. This was important because previous Fantastic Four movies had significantly altered Doom’s history and abilities. After Downey researched the character himself, he concurred with Feige that they needed to “get Victor Von Doom right.”

Doctor Doom will be a misunderstood hero

I’m really excited for Avengers: Doomsday, and I’m especially curious about how they’ll handle Victor Von Doom. He’s such a complex character in the Marvel comics – truly one of the most interesting! He’s usually portrayed as a villain, especially when it comes to stories involving the Avengers and Fantastic Four. But it’s not simple – Doctor Doom has this really strong personal code of honor, even though he doesn’t feel bad about the things he does. It’s strange, but if he gives you his word, he absolutely keeps it. There’s a lot of room for interpretation, and I can’t wait to see what they do with him! You can find more about Doctor Doom on Marvel’s official website.

It’s not uncommon to see Doctor Doom team up with Earth’s Mightiest Heroes when a shared threat arises. He’s also often depicted making questionable, even evil-seeming choices, all supposedly for the benefit of everyone. This internal struggle is central to the ongoing One World Under Doom storyline, in which Doom rises to become the ruler of Earth after taking the mantle of Sorcerer Supreme. He essentially becomes Emperor of the planet.

Watching Avengers: Doomsday, I can totally picture Doctor Doom causing enough trouble to pull in a whole bunch of heroes. It feels like it would quickly escalate into a massive, reality-spanning fight as everyone teams up against him. But here’s the twist – I suspect Doom isn’t *actually* the bad guy. My feeling is that his actions are actually meant to *prevent* something even worse, and that will be the driving force behind the story in Avengers: Secret Wars. It’s a clever setup, and I’m really intrigued to see how it plays out.

Doctor Doom seeks the MCU’s main anchor beings

A central question in many theories about the Avengers: Doomsday focuses on Doctor Doom’s exact plans. While we know the story will feature heroes from different realities, it’s unclear how they’ll all team up. The solution might be found in the newest and perhaps most surprising additions to the MCU: Deadpool and Wolverine. This could be key to understanding the larger plot.

The story featuring Deadpool and Wolverine brought forth the concept of anchor beings. Also called nexus beings, these are individuals who are incredibly important to their universe-so much so that their death would cause their entire timeline to collapse. It was confirmed that Wolverine is the anchor being for Earth-10005. This designation refers to the reality created by the Fox X-Men movies following the events of Days of Future Past.

This idea explains why Doctor Doom was looking for Franklin Richards at the end of The Fantastic Four: First Steps. Franklin has been established as an incredibly powerful being, potentially capable of taking Galactus’s place. Even if he isn’t an ‘anchor’ being, his death could very well cause his reality to fall apart. This fits with the idea that Doom wants to combine broken realities into one universe, and rule it. Doctor Doom attempted a similar feat in the 2015 Secret Wars comic book event. It seems highly likely that this is Doom’s overall plan.

Doomsday based on 2019 Doctor Doom series

An intriguing report offers some insight into Doctor Doom’s goals in Avengers: Doomsday. According to insider Daniel Richtman, the MCU version of Doctor Doom harbors a “vendetta against the Multiverse.” This is reminiscent of a storyline from the 2019 Doctor Doom monthly comic book series.

The storyline of the 2019 Doctor Doom series revolved around the ruler of Latveria being haunted by glimpses of an ideal world. In these visions, he had a happy family and the citizens of Latveria were thriving. This contrasted sharply with his current situation – wrongly accused of terrorism and with his country facing danger. Eventually, Doom discovered these visions depicted an alternate reality where he was a kind and effective leader. However, he chose to destroy that reality when his counterpart suggested forgiving his rivals, including Reed Richards.

It’s simple to imagine a different version of Doctor Doom responding to the Multiverse with the same intense anger. The idea of any universe where he isn’t completely in control could drive him to obliterate all other worlds. A Doom like that would be a significant danger, and could easily bring together all the heroes featured in Avengers: Doomsday to fight against him. The potential consequences are immense, and a unified front would likely be necessary. This is a truly frightening scenario.

Doomsday based on Ultimate Comics: Doomsday

Many ideas about Avengers: Doomsday suggest it draws inspiration from the 2015 Secret War event. This makes sense, especially considering the sequel is called Avengers: Secret Wars. That comic book centers around Doctor Doom and features the collision of different universes due to incursions. However, there’s another story with a comparable plot, which was published as Ultimate Comics: Doomsday.

Published over 12 issues between 2010 and 2011, Ultimate Comics: Doomsday revolved around a mysterious danger attempting to change the fundamental nature of the original Ultimate Universe. This threat was eventually revealed to be Reed Richards from that world. He subsequently adopted the name The Maker and became a danger to many different realities. More information can be found online.

It doesn’t seem probable that a different version of Reed Richards will actually be the main villain in Avengers: Doomsday. However, it would be a clever move to have a heroic Doctor Doom oppose such a dangerous enemy. Regardless, the story-with several hero groups fighting a villain who can change reality-does resemble the core storyline of Ultimate Comics: Doomsday.
