Avengers Doomsday plot leak reveals multiverse war and Doom's betrayal

A detailed plot leak for Avengers Doomsday has circulated online for months, and industry insiders John Campea and Robert Meyer Burnett have now confirmed it aligns with what they've heard from reliable sources. The alleged plot describes an epic multiverse saga that directly continues from Avengers Endgame, bringing together the Avengers, X-Men, and Fantastic Four against a catastrophic threat.

The Opening Incursion

The film opens with a universe-destroying incursion on Tobey Maguire's Spider-Man Earth. Deadpool and Wolverine, sent by Beast with a planet-killing device, detonate it to save their own universe from collision. Wolverine sacrifices himself in the process, and the entire world is destroyed. This opening immediately establishes the stakes by using familiar characters from the original Spider-Man and X-Men films that general audiences recognise, making the multiverse concept visceral and emotionally resonant rather than purely fan service.

Steve Rogers' Hidden Life

The film cuts to Tony Stark's funeral, where Steve Rogers returns the Infinity Stones. However, he chooses to stay in the past with Peggy Carter, starting a family and having a son named Jim, after Bucky Barnes. Before the events of Loki season 2's finale, Loki visits them and warns that the TVA will prune this timeline because Steve was never meant to exist there. Loki offers them escape to the Fantastic Four's universe, where they live peacefully for ten years.

Doctor Doom's Emergence

Doctor Doom visits Sue and Franklin Richards, warning them about coming incursions and proposing a plan to separate universes permanently using massive dimensional cannons. He asks if anyone from another universe is living in theirs and discovers Steve's family through Reed's technology. Doom convinces the Fantastic Four and Avengers to join his cause, but his true motive is far more sinister.

The X-Men Conflict

A team including Yelena, Sam Wilson, Shang-Chi, Thor, and Steve travel to the X-Men universe to recruit them. The X-Men, traumatised by surviving multiple incursions, initially attack, believing the visitors have come to destroy them. After explaining the cannon plan, tensions ease temporarily. However, Steve and Thor discover something devastating at the TVA: Loki is dead, killed by Doom, who has stolen his powers.

Doom's Betrayal and War

Steve confronts Doom in the X-Men universe, where Doom reveals his true plan: allow incursions to happen so he can rebuild the multiverse in his own image and resurrect his dead family. Doom became obsessed with stopping the incursion after Steve's presence triggered it, leading to dangerous experiments that killed his family and left him disfigured. As revenge, Doom kills Steve's son Jim in front of him.

The Avengers, X-Men, and Fantastic Four unite to march on Doom's castle in Latveria. Thor prays to Odin, who sends an army from Valhalla to join the battle. As a massive war erupts, the universes begin colliding and destroying each other, killing everyone in the conflict.

Battleworld Rises

Using Loki's stolen powers, Doom creates Battleworld from the destruction and resurrects everyone with erased memories. They believe Battleworld is all that has ever existed. Doom assumes his throne as the god emperor of this new world, a false reality of his own design.

What's Next

The leak suggests that Spider-Man, Wolverine, and Deadpool may survive in the Void when Tobey's universe collapses, retaining their memories and potentially forming a resistance against Doom's rule. This setup could lead directly into Secret Wars, positioning these characters as the leads of the next major conflict.
