Warning: This post contains spoilers for Avengers: Doomsday.
A new plot leak for Avengers: Doomsday reveals the film’s final act, which reportedly features a massive battle in Doctor Doom’s Latveria.
On X, a user shared rumored plot details that are said to be reliable, including the ending of the movie. Here’s what was revealed:
The final act is a huge war set in Latveria. After Thor finds out that Doctor Doom has manipulated everyone and reveals his true plan to control the multiverse, Thor prays to Odin and gets help from Valhalla to stop Doom and his army.
We also see Jane Foster and Heimdall. The Avengers, Fantastic Four, X-Men, Wakandans, Thor, and Valhalla warriors all come together to fight Doom.
As the battle goes on, incursions between universes begin, and the worlds start crashing into each other. Sentry holds two worlds apart for a short time using his bare hands. Then Reed’s ark (or lifeboat) arrives, but there is not enough time to save everyone. Before many people can escape, the multiverse breaks apart.
This scene feels like it was added later during reshoots because it was never mentioned earlier. The ark is made from Earth-616 Adamantium, which is strong enough to survive the end of the multiverse.
On different Earths, heroes appear and protect civilians during the Incursion. At the same time, the Young Avengers are hiding together and making plans.
Finally, everything ends. The universes collide, everything is destroyed, and Doom is the only one left with real power. Using Loki and Franklin’s powers, he creates Battleworld, a new world made from the remains of the multiverse.
After that, a text scene explains that people are brought back to life, their memories are erased, and they believe Battleworld is the only world that has ever existed. Doom becomes emperor and rules over this new reality.
The first post-credit scene is one long shot moving across Battleworld all the way to Doom’s palace. We can see what looks like the Thor Corps, but the VFX are unfinished. Galactus is standing outside Doom’s castle.
The final shot shows Doom sitting on his throne with Doctor Strange, the Invisible Woman, and Franklin Richards beside him. It hints that the Invisible Woman and Franklin may have become Doom’s family in this new reality. They all wear new costumes and look powerful and intimidating.
Recently, insider Alex Perez (via The Cosmic Circus) reported that He Who Remains may have “won” the Multiverse Saga even after his death.
“Even though he’s not in either movie, He Who Remains won. And we’ll leave it at that.”
Directed by the Russo brothers from a screenplay by their longtime collaborator Stephen McFeely and Michael Waldron.
Here’s the plot synopsis for Avengers: Doomsday:
“Doctor Doom has officially arrived on the Marvel Cinematic Universe stage. This villain, a master of cutting-edge science and powerful magic, will unleash a cascading crisis across the multiverse. Marvel’s most iconic actor, Robert Downey Jr., also returns as Doctor Doom!”
