Avengers: Doomsday plot rumours: From Doctor Doom’s multiverse plan to Thor’s alleged death, here’s what the leaks claim

Marvel’s Avengers: Doomsday has become the subject of several plot leaks and fan theories months before its release, with the rumours pointing to a multiverse-spanning story involving Doctor Doom, the Avengers, the X-Men and the Fantastic Four.

According to the various unverified plot rumours circulating online, the film could begin with the multiverse already in crisis. Multiple realities are reportedly facing Incursions, with universes on the verge of colliding and being destroyed.

One of the most talked-about rumours claims that characters from different Marvel universes could initially find themselves fighting each other before discovering that Doctor Doom is manipulating the crisis from behind the scenes.

Doctor Doom could be trying to reshape reality

The central plot speculation suggests that Doom may not simply want to destroy the multiverse. Instead, he could be attempting to save parts of it and create a new reality under his control.

Some leaks claim that Doom will exploit the multiverse's collapse to gather surviving pieces of different realities and construct a new world known as Battleworld. This would closely resemble the storyline from Marvel Comics' Secret Wars.

The rumours suggest that Doom could eventually become the ruler of this new reality, setting up the events of Avengers: Secret Wars.

Avengers, X-Men and Fantastic Four could unite

The film is expected to bring together several major Marvel superhero groups, and plot rumours suggest they may not immediately work as a team.

Some alleged leaks claim that Doom could manipulate the heroes into believing that another universe or group is responsible for the Incursion. This could result in a conflict between the Avengers and X-Men before they realise that Doom is the real threat.

The groups would then reportedly unite against Doom as the multiversal crisis becomes impossible to contain.

Steve Rogers and Thor could investigate the TVA

Another recurring rumour involves Chris Evans' Steve Rogers and Thor travelling to the TVA.

According to the speculation, the pair could discover that the TVA has been attacked while Doom searches for Loki. The God of Stories could reportedly become important to Doom's plan because of his connection to the multiverse.

Some leaks go even further, claiming that Doom could attempt to obtain Loki's power to help reshape reality.

Thor's alleged death is among the biggest rumours

One of the most dramatic unconfirmed claims concerns Thor.

Several online rumours suggest that Doctor Doom could eventually kill Thor, possibly in front of Loki. The alleged scene has been compared with Avengers: Infinity War, where Thanos killed Loki while Thor watched.

However, there is currently no reliable confirmation that Thor dies in Avengers: Doomsday, making this one of the rumours that should be treated cautiously.

Could the heroes lose?

Perhaps the biggest plot speculation is that the Avengers and their allies may fail to stop Doom.

The alleged ending would see the multiverse collapse and Doom using what remains to create Battleworld. The surviving heroes could then find themselves trapped in Doom's new reality.

That would provide a direct bridge to Avengers: Secret Wars, where the heroes could attempt to overthrow Doom and restore the multiverse.

For now, the exact plot of Avengers: Doomsday remains under wraps. While the Incursion, Doctor Doom and the meeting of Marvel's major superhero teams are central to current speculation, claims about individual deaths, betrayals and surprise appearances remain unconfirmed.
