Avengers Doomsday Doctor Doom Team: The Strongest Masked Ally Theories
The Avengers Doomsday Doctor Doom team could include heroes the film has barely mentioned. The X-Men, Fantastic Four, multiple Avengers teams, Thor, and Steve Rogers are expected to unite against Robert Downey Jr.'s Doctor Doom. That leaves one major question: which powerful characters will stand beside him?
Several missing MCU heroes and Fox-era X-Men may be hidden beneath Doom's masked robes. The theories connect trailer dialogue, reported casting, leaked images, the 2024 San Diego Comic-Con presentation, and Marvel's 2015 Secret Wars storyline.
Spoiler warning: The discussion below includes reported casting details, trailer clues, leaks, comic parallels, and fan theories about Avengers: Doomsday.
Why the Avengers Doomsday Doctor Doom team may include missing heroes
The huge cast still leaves major heroes unaccounted for
Avengers: Doomsday has a massive reported ensemble. The returning groups include the X-Men, Fantastic Four, Avengers, and two original Avengers in Thor and Steve Rogers. Even with that lineup, Wanda Maximoff, Doctor Strange, Captain Marvel, Hulk, Spider-Man, Vision, and Wolverine have been missing from major announcements.
Some absences have easy explanations. A film packed with heroes may save certain characters for Avengers: Secret Wars, while others may not fit the story. Promotional material also cannot confirm whether a character is dead, imprisoned, or working for Doom.
Hulk, Spider-Man, and Star-Lord have possible explanations
Bruce Banner may be unavailable because of his reported psychiatric-ward storyline in Spider-Man: Brand New Day. That facility could be tied to the Department of Damage Control, leaving Banner unable to join the Avengers.
Spider-Man may have a lower place in the current superhero chain of command, based on Yelena's “big potato” speech in Brand New Day. Star-Lord has a clearer reason to stay away. After the Guardians of the Galaxy's ending, Peter Quill appeared ready for retirement, and Marvel may be saving his return for Secret Wars.
Wanda and Strange are far more suspicious
Wanda and Doctor Strange feel different because both characters connect directly to the Multiverse Saga. WandaVision, Spider-Man: No Way Home, and Doctor Strange in the Multiverse of Madness all place them near the MCU's biggest reality threats.
They also play major roles in Jonathan Hickman's Secret Wars comics. Both are skilled magic users who have studied the multiverse, making their absence from a Doctor Doom story hard to explain. Their powers could help Doom control reality, memory, and the people living inside his future kingdom.
Scarlet Witch could shape Doom's Battleworld from the shadows
Wanda's powers make her valuable to Doom
In WandaVision, Wanda creates the Westview hex and reshapes an entire town around her grief. She gives the people inside it new roles, alters their memories, and builds a home with Vision and their sons, Billy and Tommy.
The story also links Billy and Tommy to versions of themselves across the multiverse. Wanda's magic reaches beyond one reality, which could help Doom build Battleworld after the multiverse collapses. Kevin Feige has also said Wanda came close to defeating Thanos in Avengers: Endgame, showing how dangerous her power can be.
Doom could use Wanda to create a false history for Battleworld. Most residents might remember only life under Doom's rule, much like the characters in the 2015 Secret Wars comics. A massive hex could make Doom appear to be the rightful ruler.
Mount Wundagore leaves Wanda's fate open
At the end of Multiverse of Madness, Mount Wundagore collapses over Wanda. A burst of red energy appears before the mountain falls, and the film never shows her body.
That leaves room for a survival theory. Deadpool & Wolverine also shows a relief of Wanda from Mount Wundagore in the Void, though the image does not confirm that Wanda herself is there. One possibility places her in the Void, where Doom could find and recruit her.
Wanda may believe Doom is saving reality
The strongest version of this theory does not make Wanda another mindless dark-magic villain. She could believe Doom's plan is the only way to stop incursions and protect what remains of existence.
That would make the red-robed witch among Doom's followers a possible Scarlet Witch. Wanda might help create Battleworld while thinking she is protecting its people. Her alliance with Doom could come from conviction, not control.
Doctor Strange and the masked sorcerers could serve Doom
The third-eye mask points toward Doctor Strange
A reported leaked image shows a masked figure called “Boris,” with a narrow opening in the forehead. The detail recalls Doctor Strange's third eye, which appeared after he used the Darkhold in Multiverse of Madness.
The comics provide another strong clue. In the 2015 Secret Wars story, Strange works for Doom as Sheriff Strange on Battleworld. The “Boris” identity is still a fan theory, but the mask design and comic connection suggest that the figure could be the MCU's Doctor Strange rather than a random variant.
Clea may have brought Strange into Doom's orbit
The post-credits scene of Multiverse of Madness gives Strange a direct path into the next multiverse conflict. Clea tells him that he caused an incursion and asks him to help fix it.
Clea understands the danger better than most characters. She may work with Doom because both want to stop reality from collapsing, or she may recruit Strange at Doom's request. Strange could cooperate without accepting Doom's rule, creating tension inside the masked group.
The colored witches may hide major characters
The masked followers wear different robe colors, but their identities remain unknown. The orange-robed figure could be the Ancient One, who first explained the MCU's multiverse and helped guide the Avengers during the time heist.
The orange robe could also hide Jean Grey, perhaps a version connected to the Phoenix Force. A green-robed witch might be Cynthia von Doom, Doom's mother, Sylvie, or even Loki. These robes may show rank within Doom's magical order rather than identify one fixed group.
Former X-Men could become Doom's most painful enforcers
Wolverine's return makes other absences suspicious
Hugh Jackman's Wolverine is expected to return after Deadpool & Wolverine and the character's reported connection to Doomsday. The film's multiverse story, the TVA, and the Void all make Wolverine a natural fit.
His absence from early material may be deliberate. One reported theory claims Wolverine becomes trapped in another universe during an incursion, possibly after fighting Tobey Maguire's Spider-Man. That could explain why the X-Men appear before Wolverine does.
Doom may have rescued Storm and Jean Grey
Storm and Jean Grey are two major Fox-era X-Men who remain conspicuously absent. The film could reveal that the X-Men have fought incursions for years and believed both women died while saving their reality.
Doom may have rescued them from collapsing universes. He could offer them another way to stop the incursions, even if that means serving his rule. Their omega-level mutant powers would make them valuable allies.
A masked reveal involving Halle Berry's Storm or Famke Janssen's Jean Grey would hit the returning X-Men hard. Cyclops seeing Jean under Doom's mask would be devastating, while Xavier finding Storm among Doom's followers could turn a cosmic battle into a personal betrayal.
Jean Grey could become Doom's Phoenix champion
The orange-robed witch may be Jean rather than the Ancient One. Doom could help her control or unlock the Phoenix Force, turning her into one of his strongest enforcers.
That reveal would fit the film's rumored unmasking scene. The Avengers may see familiar faces beneath Doom's masks, while the X-Men watch their lost friends fight for the enemy.
Rogue could explain Captain Marvel's disappearance
Rogue's powers support a villainous alliance
Rogue can absorb powers, memories, and abilities through physical contact. In the comics, she has worked with the Brotherhood of Mutants and once absorbed Carol Danvers' powers.
Reported MCU casting has connected Rogue to the new X-Men story, though her role remains unconfirmed. A Rogue working for Doom could absorb abilities from major heroes and help build his power base.
Captain Marvel may be a trophy, not a casualty
Doom's cape clasp appears to resemble Captain Marvel's insignia. That detail has led to a theory that the clasp is a trophy from a battle with Carol Danvers.
Captain Marvel does not need to be dead. Doom could capture her early and lock her inside his castle, removing one of the greatest threats to his plan. Rogue might then transfer some of Carol's power to Doom, though this remains pure speculation.
The MCU already shows that powerful sorcerers can remove or alter abilities. Rogue may not be essential to Doom's plan, but her presence could help set up future conflict between mutants and established heroes.
Ghost Rider could add Hell to Doom's roster
“Hell answers to me” may point to Mephisto
In a recent Doomsday trailer, Doom says, “Hell answers to me.” The line may connect to his comic-book history, where he tries to save his mother, Cynthia von Doom, from Hell and Mephisto.
That does not prove Doom controls Mephisto or the afterlife. It does suggest that supernatural forces may be part of his plan.
Ryan Gosling's Ghost Rider could appear early
Reported casting has linked Ryan Gosling to the MCU's Ghost Rider, and rumors suggest the character may appear before a solo film. Doom's victory over Mephisto could give Ghost Rider a reason to follow him.
A multiversal story could also bring back Nicolas Cage's Ghost Rider. Either version would add a supernatural fighter to a roster already filled with sorcerers, mutants, and reality manipulators.
The masked unmasking could define Avengers: Doomsday
Doom's followers may think they are saving reality
Doom's best recruits may not see themselves as villains. Strange, Wanda, Jean, Storm, or Sylvie could believe that one ruler must control the remaining realities to stop total collapse.
That creates a direct clash with the Avengers. The heroes would fight for free will and separate worlds, while Doom's allies would argue that freedom caused the crisis.
Tony Stark's face could be the final reveal
The rumored unmasking scene could begin with Doom's followers removing their masks. Cyclops might see Jean, Xavier might see Storm, and the Avengers might recognize other lost allies.
The final reveal would come when Doom removes his own mask and Steve Rogers, Thor, and the other Avengers see Tony Stark's face. Doom would not be Tony, but his connection to that face would make the conflict painfully personal.
Conclusion
The strongest Avengers Doomsday Doctor Doom team theories place Wanda among the red-robed witches and Doctor Strange behind the “Boris” mask. Clea may serve Doom, while Jean Grey and Storm could be rescued X-Men from dying realities. Rogue might connect Doom to Captain Marvel's absence, and Ghost Rider remains the boldest possibility.
None of these identities are confirmed. The clues come from reported casting, trailers, leaks, Comic-Con footage, and comic-book parallels. Still, Doom's greatest weapon may be his ability to convince heroes that serving him is the only way to save the multiverse.
The biggest question is not who will fight Doom. It is who will remove a mask and reveal that they chose his side.
