Avengers: Doomsday Explained: Track the MCU Storylines Behind Doctor Doom’s Multiverse War
Doctor Doom may not be trying to conquer the multiverse for power alone. He could be reacting to the timelines, choices, and losses caused by heroes such as Steve Rogers, Wanda Maximoff, and Peter Parker. That question sits at the center of Avengers: Doomsday.
Marvel has confirmed that heroes from three distinct universes are heading toward a collision. To understand the conflict, you need to track Steve’s alternate life, Loki’s multiverse tree, weakened barriers between realities, the return of the X-Men, and Doom’s possible connection to Earth-828.
Why Avengers: Doomsday Begins With Steve Rogers
Steve and Peggy created a dangerous branch
In Avengers: Endgame, Steve Rogers travels through time to return the Infinity Stones. He was expected to return at once, but he stays in the past and lives with Peggy Carter. He later appears as an old man, leaving one major question: did he live inside the original timeline or create a new branch?
The Russo brothers’ interpretation supports a separate reality. Endgame already showed that time travel can create new timelines, so Steve’s decision may have caused a larger disturbance than the film revealed. Steve and Peggy are both expected to return in Avengers: Doomsday, making that hidden chapter important again.
The 2012 Tesseract escape proves how one choice can change everything. Tony Stark and Scott Lang fail to recover the Tesseract, allowing a Loki variant to escape. The TVA later prunes that branch, but the escaped Loki becomes the lead character of the Disney+ series.
Doom may blame Steve for a stolen life
Recent footage shows Doom accusing the heroes of living “stolen lives.” It also shows characters with children, including Steve holding a baby. That detail has fueled a major theory about Steve and Peggy.
If their branch later collided with Doom’s universe during an incursion, it might have destroyed his family or home. Doom could then see Steve’s peaceful life as something bought with another family’s suffering. This remains unconfirmed, but it would give Doom a personal reason to fight the Avengers.
Loki and Wanda Hold the Keys to Avengers: Doomsday
Loki turned the timeline into a living multiverse
Sylvie’s killing of He Who Remains caused the Sacred Timeline to branch without control. In Loki Season 2, the TVA’s Temporal Loom begins to fail because it was never built to support endless timelines. It was a safety system designed to destroy extra branches and protect He Who Remains’ chosen timeline.
Loki destroys the Loom and walks into the dying branches. Using his power, he revives the timelines and gathers them into a giant tree that resembles Yggdrasil. He now sits alone at its center, keeping the multiverse alive.
Tom Hiddleston’s return makes Loki’s role central to Doomsday. Any plan to reshape, control, or save the multiverse may lead Doctor Doom to the God of Stories.
Wanda’s grief became a multiversal threat
In WandaVision, Wanda creates the Hex around Westview after losing Vision. Inside the Hex, she lives with a rebuilt Vision and their sons, Billy and Tommy. Thousands of residents remain trapped under her control until Wanda understands the harm she has caused and ends the spell.
After defeating Agatha Harkness, Wanda takes the Darkhold. The book helps her study her powers, but it also corrupts those who use it. When Wanda learns that other versions of Billy and Tommy exist, grief becomes an obsession that leads into Doctor Strange in the Multiverse of Madness.
Spider-Man, Kang, and the Incursions
Peter Parker made universes bleed together
After Mysterio exposes his identity, Peter asks Doctor Strange to make everyone forget he is Spider-Man. Peter keeps changing the spell while Strange casts it, causing people from other universes to enter Earth-616.
Green Goblin, Doctor Octopus, and other villains arrive, followed by Tobey Maguire’s and Andrew Garfield’s Spider-Men. Peter and the other Spider-Men cure the villains, but the damaged spell begins opening cracks across reality.
Strange finally casts a new spell that makes everyone forget Peter Parker completely. Peter saves reality, but he loses his friends and family. The film proves that weakened barriers can allow separate universes to overlap, which helps explain the incursion threat in Doomsday.
Kang’s fall cleared the way for Doom
The Multiverse Saga originally built toward Kang. Loki introduced He Who Remains, while Ant-Man and the Wasp: Quantumania introduced Kang the Conqueror. Kang claimed to have destroyed countless timelines and killed Avengers across different realities.
Marvel first announced the next Avengers movie as Avengers: The Kang Dynasty. After Jonathan Majors’ 2023 conviction for reckless assault and harassment, Marvel cut ties with him. The studio later replaced Kang Dynasty with Avengers: Doomsday, brought back the Russo brothers, and cast Robert Downey Jr. as Doctor Doom.
Kang’s story may not vanish completely. Marvel can still reuse its ideas about variants, timeline wars, and multiversal collapse through Doom’s conflict.
The X-Men and Fox Universes Join the Collision
Monica Rambeau may be trapped near the coming war
At the end of The Marvels, Monica Rambeau uses her powers to close a tear between realities. She becomes trapped on the other side and wakes in a parallel universe where her mother, Maria, is alive.
This Maria has no memory of Monica and operates as the hero Binary. Beast, played by Kelsey Grammer, then appears and confirms that Monica is in another reality. Since Beast, Professor X, Magneto, Cyclops, Mystique, and Nightcrawler are returning in Doomsday, Monica may be trapped in one of the universes about to collide with Earth-616.
Doom is using the X-Men’s worst weapon
X-Men: Days of Future Past opens in a future ruled by Sentinels. The mutant-hunting machines eventually target humans who carry genes that could produce mutant children. Wolverine’s consciousness travels back to 1973 to stop Mystique from killing Sentinel creator Bolivar Trask.
Mystique spares Trask, changing history and erasing that future. New Doomsday footage shows Doom activating Sentinels against the X-Men. Using the machines against mutants gives Doom a powerful weapon and a cruel symbol of what the X-Men once escaped.
The TVA connects the Fox universe to Marvel
Deadpool & Wolverine identifies Deadpool’s home reality as Earth-10005. The TVA says the universe is dying because its anchor being, Wolverine, is dead after Logan.
Deadpool searches for another Wolverine and eventually reaches the Void, a place tied to discarded people and realities. The film brings back Blade, Elektra, X-23, and Gambit, proving that older Marvel movie universes now fit inside the MCU’s multiverse. The TVA gives Doomsday a direct path to those legacy characters.
New Avengers, Shang-Chi, and Earth-828
Sam Wilson leads a divided Avengers
Steve gives Sam Wilson the shield at the end of Endgame, but Sam first rejects the title and places the shield in the Smithsonian. The government then gives it to John Walker, who loses control after Lemar Hoskins dies and kills a Flag Smasher with the shield.
Sam and Bucky reclaim it. Sam trains with the weapon, receives a Wakandan suit, and becomes Captain America on his own terms. That distinction matters in Doomsday: Sam is the current Captain America, even if Steve Rogers also returns.
Thunderbolts adds another Avengers-branded team. Yelena, Bucky, Red Guardian, Ghost, and John Walker defeat Sentry by reaching Bob Reynolds through the Void inside him. Valentina publicly introduces them as the New Avengers, creating possible tension with Sam’s team.
The Ten Rings still hide a major answer
Shang-Chi inherits the Ten Rings after his father, Wenwu, dies. The weapons are more than 1,000 years old, and neither Bruce Banner nor Captain Marvel can identify their technology.
Wong discovers that the Rings transmit a beacon to an unknown location. Shang-Chi is returning in Doomsday, giving Marvel a chance to connect the signal to Doom, the multiverse, or another cosmic force. No answer has been confirmed.
Doctor Doom may come from Earth-828
The Fantastic Four: First Steps takes place on Earth-828, a retro-futuristic 1960s universe. Reed Richards, Sue Storm, Johnny Storm, and Ben Grimm are already famous heroes there. A vacant seat for Latveria during a United Nations meeting hints that Victor von Doom may be tied to this universe.
After the family defeats Galactus, Franklin Richards displays immense power by bringing Sue back to life. A mid-credit scene then shows a hooded Doom approaching Franklin while holding his metal mask. Earth-828 looks like Doom’s home, but Marvel has not confirmed it.
What to Rewatch Before Avengers: Doomsday
Start with Avengers: Endgame and Loki Seasons 1-2 for the branching timelines, TVA, Temporal Loom, and Loki’s sacrifice. Then watch WandaVision, Spider-Man: No Way Home, and Doctor Strange in the Multiverse of Madness to follow Wanda’s magic and the damage caused by Peter’s spell.
For the returning factions, revisit The Marvels, Shang-Chi and the Legend of the Ten Rings, Captain America: Brave New World, Thunderbolts, The Fantastic Four: First Steps, Deadpool & Wolverine, and X-Men: Days of Future Past.
Keep the confirmed facts separate from theories. Loki is sustaining the timelines, Sam is Captain America, the X-Men are returning, Shang-Chi is involved, the Fantastic Four have reached Earth-616, and Downey is playing Doom. Steve causing Doom’s tragedy, the Ten Rings’ connection to Doom, and a direct Loki-Doom fight remain unconfirmed.
Conclusion
Avengers: Doomsday is built on years of unfinished stories. Steve’s branch, Loki’s multiverse tree, Wanda’s Darkhold, Peter’s spell, Monica’s displacement, the TVA, the Ten Rings, and Earth-828 all point toward the same crisis: realities are moving toward collision.
Doom may want control, but grief could drive him more than conquest. He may believe the heroes are living stolen lives while his own family was erased by the multiverse. Steve’s role in that tragedy remains a theory, yet the larger danger is confirmed.
Loki guards the timelines. Sam Wilson leads as Captain America. The New Avengers are active, the X-Men are entering the fight, and Shang-Chi’s Rings still call into the unknown. Rewatch the connected projects before Avengers: Doomsday to see which clues become answers.
