Avengers: Doomsday Plot Leak Reportedly Details Sentinels, a Fake Peggy, and Doctor Doom's Tragic Origin

A new plot leak for Avengers: Doomsday has surfaced, and it is the most detailed one that has circulated so far. From what I've read, it lines up well with everything reported previously, and it fills in gaps that earlier leaks left open, including why Sentinels show up near the X-Mansion in the trailer and how a fake version of Peggy Carter factors into the story.

Sentinels and Magneto Reportedly Wipe Out an Entire Earth in the Opening Scene

The film reportedly opens on Earth 96238, where a group of Sentinels travels with Magneto to New York City carrying a destructive bomb. Deadpool and Wolverine discover that Tobey Maguire's Spider-Man is present, and a rooftop fight breaks out. Spider-Man beats them, but it is too late. Magneto and his allies have already destroyed New York and New Jersey by the time the fight ends.

Wolverine tries to explain what is happening, but Magneto shows up and steals the device needed to activate the bomb. Spider-Man attacks Magneto and loses. Wolverine tries to save him, but there is no time to escape, and that Earth explodes while Professor X watches through his window as Magneto and Deadpool return through a portal, leaving Wolverine behind.

This tracks with everything reported previously, and it explains why the Sentinels appear near the X-Mansion later, when Doom raises them up and controls them with magic. As for whether Wolverine and this Spider-Man are actually dead, I don't buy it. The story seems built to make you believe that, but I don't think that's where it ends.

Steve Rogers Reportedly Stays With Peggy and Has a Son Named Jim Before Loki Intervenes

The story shifts to Tony Stark's funeral, after which Steve Rogers sets out to return the Infinity Stones. While traveling through time he decides to stay with Peggy, and the two have a son named Jim. One day Loki visits them, and Steve immediately suspects an attack, but this Loki calms him down and explains he is not the version Steve fought in the first Avengers film, though he is descended from him, now a godlike figure who oversees the timelines of the multiverse.

Loki warns Steve that the Time Variance Authority's presence in this era is causing an invasion and that the timeline will soon be destroyed because Steve was never supposed to stay there or have a child. When Loki mentions an invasion, I immediately wondered if that's a hint at Kang. I really hope it is.

To save them, Loki offers a way out: he transports Steve's family to a universe where they don't exist and won't be found, the Fantastic Four's universe. Before leaving, he gives Steve a card to contact him, the same card seen in the trailer. Steve and his family accept and live there for ten years.

Doctor Doom Reportedly Meets the Fantastic Four Ten Years Later as a Sorcerer King of Latveria

Ten years later, Reed Richards, Johnny Storm, and Ben Grimm are at a baseball game when an accident with the stadium fence prompts Steve and Jim to help. Ben notices something unusual, and the group gets a burglary alert from the Baxter Building. Racing home, they find everything calm, and they find Doctor Doom there with Sue Storm, Herbie, and Franklin.

Reed already knows Victor well, since the two studied together at university along with Ben. Victor now rules Latveria, a country with a complicated status. He lost his wife and son, and he only became ruler of Latveria after overthrowing a brutal regime with his Doombots. As the leak puts it, Victor is essentially Earth's version of Doctor Strange, a master of magic and sorcery, which I love. Because of that, and the rumors of witchcraft around him, Sue is nervous.

Victor warns Reed that he believes their Earth will be the next victim of the invasion, explaining that when the fabric between two realities tears, the centers of each reality are drawn together, and once an invasion succeeds, both universes stop existing. Reed and Victor find three anomalies on their Earth in the same location, which turn out to be Steve and his family, now grown into a life together, with Steve sporting a beard and long hair and James around ten or eleven years old.

Thor and the Avengers Reportedly Reunite With Steve Rogers Aboard the Excelsior

Thor and his adopted daughter Love are traveling together, but Love is having nightmares about invasions. Thor goes to New Asgard, where Valkyrie and an Asgardian doctor are examining a young girl dying from the multiverse's collapse. Valkyrie gets word that the Fantastic Four's ship, the Excelsior, has arrived on Earth, and Sam Wilson's Avengers are notified as well.

Thor boards the ship and is shocked to see Steve, not fully believing it's him until Steve picks up Mjolnir. That could explain the "it's not possible" line from the trailer, with Thor being the first to react before Steve grabs the hammer. I had wondered if that line belonged to Doom disguised as Robert Downey Jr.'s character, but based on this leak we never actually see his face, so Steve makes more sense.

As soon as they dock at the new Avengers Tower, Sam's team arrives and immediately argues with Bucky over which team should take command, which tracks perfectly. Scott Lang has a small reunion with Ghost. Steve reconnects with Sam, Scott, and Bucky, and shares a touching moment with Yelena Belova as they discuss Natasha, a scene I've heard about for a while and am glad is being included.

The Avengers Reportedly Turn to Wakanda and Talokan as the Multiverse Crisis Worsens

Steve brings both Avengers teams together with a Captain America style speech focused on the invasions and the wider cosmic crisis, which is exactly what I'd expect. Sam and Steve plan to travel to Wakanda, while Shuri tells Sam she is already working on a solution of her own. The group reunites with Wakanda, and Steve is shocked to learn of T'Challa's death, which I'm glad they included for continuity and what should be a touching moment, maybe even a small tribute to Chadwick.

A smaller group heads to Talokan, where the effects of the crisis are visible, the sky has turned red, and Namor has used all the water that normally filled Talokan to build a massive barrier around it, which may explain the parted sea seen in the trailers. Sue crosses the barrier and finds Namor extremely hostile and unwilling to cooperate, but she manages to unite the people of Wakanda and Talokan.

Back in Wakanda, the group learns there is no solution. Reed starts to believe the multiverse's fate always ends in death but stays open to other options. Doom suggests attacking the X-Men's Earth to stop the incursion between universes 828 and 616. Sam wants diplomacy, Namor wants bloodshed, and Scott dismisses the quantum dimension while mentioning his encounter with Kang, prompting a look from Doom. Steve rejects using the Infinity Stones again, blaming them for their situation, which I liked as a small Kang nod, though I wanted something bigger.

Reed Richards Reportedly Devises a Plan to Build Three Separation Cannons

Reed jokes that Galactus would be useful here, but nobody knows where he is, and they aren't even in the right universe for that anyway. The joke sparks an idea: what if they use the same technology used to exile Galactus? Reed proposes building three cannons, one on each Earth, to figuratively pull the universes apart, but time is running out.

Steve splits everyone into three teams. One stays in Wakanda to build a cannon there, since Wakanda already has the technology to replicate what the Fantastic Four did. A second team travels to Earth 828 to build a cannon at the Baxter Building. The third and most important team must travel to Earth 10005, the X-Men's universe, and convince its heroes to go along with the plan.

That final team reportedly includes Doctor Doom, Reed Richards with Herbie, Sam Wilson, Yelena Belova, and Shuri, characters already glimpsed together in the trailer and in an earlier leaked scene, so this checks out. Steve feels uneasy around Doom and tells Thor and Loki, and the two decide to head to the TVA using the map Loki left behind. Sue and Shuri also sense something is wrong with Victor and start looking into it on their own.

The Mission to the X-Men's Earth Reportedly Turns Into an All-Out Brawl at the X-Mansion

The team bound for Earth 10005 travels by Quinjet and lands at the X-Mansion, where they're immediately captured by a group of Guardians defending the building, while Doom stays outside for cover. I've been saying this would happen the entire time. The X-Men have survived many invasions and trust no one, believing the visiting heroes have come to destroy them, so they attack without hesitation.

Nightcrawler stalks the group through the halls before they reach the Danger Room and encounter Mystique. Yelena ignores Reed's orders and attacks. Mystique shifts into Yelena's own form and then into Natasha's, which is a detail I question, since it's unclear how Mystique would even know about Natasha, though it clearly rattles Yelena before she regains the advantage. Shuri fights Gambit to an evenly matched draw, and Reed's attempt to contain Deadpool ends with a comedic beat lifted from Deadpool 2, where Wade sits on Reed's swollen face.

Cyclops fires an optic blast at Sam Wilson so destructive it appears to kill him, which I liked as a bit of justice for the X-Men. Beast realizes the visitors pose no real threat and leads them to the medical bay, where Monica Rambeau is being treated after being trapped in this universe following the Marvels, gravely ill from being in the wrong reality, a detail that is a little strange given Steve never got sick from the same kind of dislocation. Reed and Doom eventually meet with Charles Xavier and Magneto, present their plan to build the separation cannons instead of using destructive bombs, and convince them to join.

Steve and Thor Reportedly Find the TVA Destroyed and Loki Dead

While that mission unfolds, Steve and Thor arrive at the TVA using Loki's map and find it destroyed, with corpses everywhere. Mobius, who had gone there himself, helps them track Loki to the end of time, where they find him dead at the foot of the throne, his heart torn from his chest. "I hate this. I hope they change it."

The Watcher appears and tells Steve and Thor that Followers of Doom were responsible, then brings them to Earth 10005 because everyone there is in danger. This detail actually fills in a gap I'd been wondering about, since it explains how Steve and Thor end up in the X-Men's universe right as the fight there is breaking out.

Doctor Doom Reportedly Unleashes the Sentinels and Abducts a Scarlet Witch

Reed is confused when Steve and Thor arrive shouting that Doom has followers, destroyed the TVA, and killed Loki, and that's when the fight breaks out. Doom ultimately controls what the leak calls "the Guardians," which are simply the Sentinels. The mutants and Avengers can't defeat them on their own, but the Brotherhood arrives to help, and this universe's Scarlet Witch, along with Polaris, Quicksilver, and other mutants, destroys the Sentinels with relative ease, which felt a little off to me given how the rest of the fight is described.

Doom finds this universe's Scarlet Witch, which turns out to be what he was after the whole time. Steve tries to save her, but Doom's attack stuns him and she's kidnapped. Victor then uses what's called the ultimate annihilator to destroy the X-Men's world entirely. The surviving heroes, including Reed and Herbie, escape by boarding a ship just before that universe is wiped out, confirming earlier reports that Doom was hunting something specific there, apparently this reality's Scarlet Witch.

The Fake Peggy Twist Reportedly Leads to James's Kidnapping and the Attack on the Baxter Building

Back together, Steve says he has to save his family, Peggy and James. Peggy tells Doom where they are, at the Baxter Building, and he orders the attack, at which point she reveals her real identity and kidnaps James, confirming that the Peggy Steve had been living with was fake all along. New York comes under attack, and the Baxter Building is shown about to explode with everyone inside, with Doom's followers having tricked the Avengers and the Fantastic Four into the ambush.

Franklin saves everyone in the building, and Charles Xavier reportedly admires him as an Omega level mutant, a moment I loved. Thor travels to Earth 616 and a new group arrives, including Jane Foster, Heimdall, and a different Loki, along with the people of Wakanda, M'Baku, Valkyrie, and Korg. Only two Earths remain in the multiverse at this point, and a portal opens leading first to Earth 616 and then to Earth 828 for the final confrontation, with the Fantastic Four, Avengers, and X-Men converging from one side and Thor's forces from the other. That is going to be an extremely large moment to see play out on screen with all of those characters arriving together.

Doctor Doom's Tragic Origin Is Reportedly Revealed as He Kills Steve's Son

Victor returns Steve to his castle in Latveria. Steve follows Peggy to an altar with a chair marked by a symbol glowing with green magic, and Doom's followers surround him as the witch is revealed to be Death. Doom arrives holding a crying James and begins explaining that Steve's interference caused his downfall. Victor says he was once a family man just like Steve, that he studied the multiverse long before it began collapsing, and that he had a wife and a son.

Ten years ago, during a routine experiment, an anomaly occurred right as Loki transported Steve to Earth 828, causing the experiment to fail and killing Doom's wife and son while leaving Victor horribly disfigured. Doom then kills James, stabbing him instantly. Three witches are present, Death, the Ancient One, and Clea, alongside a right hand man wearing a helmet with a third eye, who the leak assumes is a corrupted version of Doctor Strange. Doom is said to have personally ripped Loki's heart from his chest, and it's now on display in his castle.

Victor reportedly corrupted Strange and Clea in the dark dimension, convincing them only he could save the multiverse, which is exactly what I expected would happen. He prepares his followers and Doombots to fight the coming invaders, ordering Strange to cast a spell using both Loki's heart and Wanda Maximoff's magic from a book that, in the comics, grants its user the power to alter reality while also corrupting them, though it doesn't let them alter reality outright. Doom's followers are described as the leaders of each destroyed universe, and his goal is to let the final invasion happen and rebuild the multiverse to bring back his lost family.

The Final Multiversal War Reportedly Ends With Doom Altering Reality Itself

Sentry senses something is wrong and encounters Vision with Tommy and Billy at Avengers Tower, where Vision activates Tony Stark's protocol calling every hero in the world, realizing the invasion can't be stopped. On Earth 828, the heroes arrive in Latveria from the Baxter Building while Thor's army arrives from Earth 616, and Deadpool returns, having abandoned the Earth 10005 group, bringing a multiversal team including Blade, Elektra, and Phantom Rider.

The war becomes a battle between the two remaining realities. Namor and Shuri work together, with Namor triggering a tsunami against Doombots while Shuri infiltrates Doom's castle with Bucky to rescue Steve. On Earth 616, the sky turns red as hordes of Doombots and villains attack New York, and heroes including Tom Holland's Spider-Man, Punisher, the Defenders, Wong, America Chavez, Cassie Lang, Kate Bishop, Kamala Khan, Star-Lord, Vision, She-Hulk, Hulk, and Captain Marvel with the Guardians of the Galaxy all answer Vision's call, which is a genuinely cool use of that Stark protocol idea.

Vision warns that the next Earth is about to launch a direct attack, and Sentry flies into space to try to stop it with his bare hands, buying time for others to escape before he runs out of time. On Reed's ship, built to survive the collapse of the multiverse, Sue stays behind and is said to be pregnant, which would set up Valeria for a future film, while Charles Xavier links minds with the mutants and Avengers so they can communicate. One of the witches intercepts the transmission, teleports aboard, kills Charles Xavier, and kidnaps Sue and Franklin, arriving too late for Cyclops, Reed, Sam, and Magneto to stop it.

At Doom's castle, the assembled heroes fight through his Doombots and followers, and Doom defeats them one by one. Steve's strike with Mjolnir shatters the hammer, and Doom counters with a sword. Bucky sacrifices himself to save Steve. The three witches kill Ghost Rider, and Doom's follower fights Yelena and Shuri, with Shuri managing to defeat her opponent but dying from her wounds. Thor calls on Odin's power for a new yellow armor and lightning, but Doom drains his strength mid fight and cuts off his hand with the sword, defeating the rest of the Avengers. Reed's ship automatically activates and leaves without Sue and Franklin as Sentry crashes and the two worlds begin to collide. Strange finishes the spell just in time, Doom alters the multiverse, reality as it exists ceases, the two Earths collide, and the film ends on Doom in white armor seated in a chair beside Doctor Strange.

That's an intense way to end things, and based on everything reported so far, I'd say roughly 80 percent of this leak is accurate, maybe more. There are a few details, like the mutants of that universe defeating the Sentinels so easily, that go against what's been reported elsewhere and give me some qualms, but the overall shape of it lines up with what's been circulating.

Let me know what you think about all this.
