The alleged Avengers: Doomsday plot leak has surfaced online, and if true, it sets up the biggest Multiverse event in MCU history — leading directly into Battleworld and a full Doctor Doom takeover.
Here’s the complete breakdown of the rumored storyline, including Incursions, Loki’s fate, Steve Rogers’ role, the X-Men conflict, and how Doom becomes Emperor.
Opening Scene: Tobey Maguire’s Spider-Man Earth Is Destroyed
The film reportedly opens in New York City on Tobey Maguire’s Spider-Man Earth.
Deadpool and Wolverine arrive carrying a planet-killing bomb built by Beast, sent to destroy this Earth in order to prevent an Incursion threatening their own universe.
- Tobey’s Spider-Man fights Wolverine.
- Wolverine successfully plants the device.
- He stays behind as it detonates.
- Tobey’s Spider-Man, Wolverine, and everyone on that Earth die.
- Deadpool escapes back to his universe.
Charles Xavier watches the destroyed world in sorrow — but they had no choice.
Tony Stark’s Funeral & Steve Rogers’ New Timeline
We cut to Tony Stark’s funeral.
Steve Rogers returns the Infinity Stones — but instead of coming back, he chooses to stay in the past with Peggy Carter. They build a life together and have a son named Jim.
Before the events of Loki Season 2’s finale, Loki visits Steve and warns him:
- The TVA will prune this timeline.
- Steve was never meant to live there.
- His son was never supposed to exist.
Loki offers them an escape: relocate to a universe where they don’t exist — the Fantastic Four’s universe.
Steve accepts.
They live there peacefully for ten years.
Doctor Doom Enters – The Incursions Are Coming
Doctor Doom visits Sue Storm and Franklin Richards. He seeks Reed Richards.
Doom warns that:
- Their universe is next to face an Incursion.
- The Multiverse is collapsing.
- Only drastic action can stop it.
However, Doom detects an anomaly — someone from another universe living there.
It’s Steve Rogers and his family.
They confront Steve and ask him to travel to Earth-616 to convince the Avengers to trust Doom’s solution.
Steve agrees.
The X-Men Conflict
The heroes then visit the X-Men’s universe.
The X-Men are hostile.
Having survived multiple Incursions, they trust no one. They believe the Avengers and Fantastic Four have come to destroy them and attack.
Doom and Reed reveal their solution:
Build massive cannons on each Earth to permanently separate universes and stop Incursions.
The teams split up to install these devices across different realities.
Loki’s Death & Doom’s True Plan
Meanwhile, Steve tells Thor that Loki is alive.
Using Loki’s contact card, they locate the TVA.
When they arrive:
- Everyone is dead.
- Loki’s heart has been ripped out.
Steve confronts Doom — and the truth is revealed.
Doom never intended to stop the Incursions.
His real plan:
- Let the Multiverse collapse.
- Rebuild it in his own image.
- Resurrect his dead family.
He takes Steve to Latveria, where masked witches serve him. One impersonates Peggy to manipulate Steve.
Doom reveals something devastating:
Steve’s presence in the Fantastic Four universe triggered their Incursion.
Doom’s failed experiments to stop it killed his own family and disfigured him — forcing him into the armor and mask.
As revenge, Doom kills Steve’s son in front of him.
Final Battle: Avengers, X-Men & Fantastic Four Unite
War erupts.
The Avengers, Fantastic Four, and X-Men march on Latveria.
Thor prays to Odin, who sends an army from Valhalla to join the battle.
As they fight, the Earths begin colliding.
The Multiverse collapses.
Every universe crashes into one another.
Everyone dies.
Everyone except Doctor Doom.
Battleworld Is Created
In the final twist:
Doom stole Loki’s powers.
Using them, he:
- Survives the Multiversal collapse.
- Creates Battleworld.
- Resurrects everyone.
- Erases their memories.
They believe Battleworld is the only reality that has ever existed.
Doom sits on his throne as the Emperor of Battleworld.
Setup for Secret Wars is complete.
Final Thoughts
If this Avengers: Doomsday plot leak is real, it positions Doctor Doom as the ultimate Multiverse villain and sets up one of the darkest MCU storylines ever:
- Tobey Maguire’s Spider-Man dies
- Loki is murdered
- Steve Rogers loses his son
- The Multiverse collapses
- Doom becomes God
This would directly lead into Marvel’s Secret Wars adaptation — with Battleworld as the central setting.
