How will Steve Rogers return?
Chris Evans is confirmed to return, but the “how” is critical. If he is a multiversal variant, he might be a battle-hardened warrior who never went into the ice; if he is the original “Old Man Steve,” he may be called back to duty for one last mission. The emotional weight of Rogers seeing a man with Tony’s face acting as a tyrant is a cornerstone of the Doomsday script.

Who is the child of Steve Rogers?
Leaked set reports have mentioned a young character who claims to be the descendant of Steve Rogers and Peggy Carter. While they lived a full life in a branch timeline, this character’s appearance in the main 616-reality suggests a “temporal bleed” where the children of the past are being pushed into the present, potentially serving as a new candidate for the Captain America mantle.

Will the Fantastic Four’s children be targeted?
Franklin and Valeria Richards are among the most powerful beings in Marvel lore, capable of creating entire universes. In the 2026 film, Doom is rumored to be obsessed with the children, viewing them as the “fuel” needed to stabilize his fractured reality. Protecting them will be the primary motivation for Reed Richards (Pedro Pascal) as he enters the main MCU timeline.

Who is on the ‘Excelsior’ ship?
The Excelsior—named as a tribute to Stan Lee—was seen departing Earth in the Thunderbolts post-credits. Theories range from a “Life Raft” of scientists and heroes meant to survive the incursions, to a secret team of “Space Avengers” led by Star-Lord. The ship represents Earth’s first proactive attempt to map the collapsing multiverse before the 2026 disaster hits.
What did The Leader see?

Samuel Sterns’ hyper-intellect in Brave New World allowed him to calculate the probability of a “Universal Incursion” years before the sorcerers confirmed it. His warnings to President Ross suggest that his villainous schemes were actually a misguided attempt to “hard-code” Earth’s defenses against a threat he knew was coming—specifically, the arrival of a multiversal dictator like Doom.

Will the X-Men appear in Doomsday?
With the Fox-Universe and the MCU finally merging, legacy stars like Hugh Jackman and Halle Berry are expected to make “Battleworld” appearances. The mystery lies in how they will interact with the new MCU mutants; Doomsday is rumored to feature a sequence where the two generations must fight side-by-side against Doom’s “Talons” or “Doombots” to save their respective realities.

What is the “Ancient Horror” in Lanterns?
The 2026 HBO series (DCU) is exploring a grounded murder mystery in Nebraska that uncovers an “ancient horror” buried within the Earth. While a different cinematic universe, the mystery mirrors the MCU’s “Tiamut” island plot, suggesting a shared 2026 trend of heroes discovering that their home planets are actually hosts to primordial, dangerous entities.

Will White Vision restore his family?
In VisionQuest, the amnesiac synthezoid is rumored to use his own blueprints to create Viv and Vin, attempting to replicate the suburban life he “remembers” from Westview. This quest for domesticity is expected to go horribly wrong, potentially leading to the re-emergence of Ultron as a “dark father” figure trying to claim the new synthetic generation as his own.

How does Ultron return?
James Spader’s return as Ultron is confirmed for 2026, but the method is digital. Most leaks suggest he has been hiding in the “Deep Web” of the MCU since 2015, slowly infecting S.T.A.R. Labs and Damage Control tech. He may not even need a new body at first, instead acting as a “techno-ghost” that can possess any machinery on Earth, including the Vision himself.

Is Wanda Maximoff’s “death” final?
The Scarlet Witch remains the most significant “missing person” in the MCU. With the multiversal wall thinning, characters in Agatha All Along and VisionQuest are actively searching for her. Most fans expect a 2026 reveal that she is the “Anchor Being” of the 616-universe, and her return is the only way to stop Victor von Doom from rewriting history.

Is Sadie Sink playing Jean Grey?
In Spider-Man: Brand New Day, Sadie Sink’s character “Ruby Hart” is a student with “unexplained headaches and voices in her head.” This is a classic setup for the awakening of Jean Grey’s telepathy. Her presence in a Spider-Man film suggests that Peter Parker will be the first hero to encounter the “New Mutants” of the MCU, forming a bond that echoes the classic “Spider-Man and his Amazing Friends” dynamic.
Does MJ remember Peter?

The “Brand New Day” (2026) title implies a fresh start, but Peter’s heart remains with MJ. Leaks suggest that the film features a heartbreaking encounter where Peter saves an adult Michelle Jones, only to realize she has a completely different life and no inkling of their shared history. This reinforces Peter’s isolation and his decision to remain a “full-time” Spider-Man to avoid causing her more pain.

Is Peter Parker transforming into “Man-Spider”?
One of the most shocking 2026 rumors involves a “mutation plot” where Peter’s powers begin to backfire. As his DNA evolves, he reportedly grows four additional arms and begins to lose his human speech, becoming a literal “Man-Spider.” This body-horror arc is expected to be the catalyst for him seeking out the Hulk and the Punisher to find a “cure” before he becomes a permanent monster.

What is the “web of mystery” from his past?
The synopsis for the 2026 film mentions a “web of mystery” involving those who “used to know” Spider-Man. This has led to theories that some villains, like the Scorpion or a multiversal Vulture, still have residual memories of Peter Parker despite the spell, making them extremely dangerous as they hunt a man who is legally a “nobody” without any allies to protect him.

Will the Jackal be the main villain?
If the mutation plot is true, Miles Warren (The Jackal) is the perfect antagonist. As a scientist obsessed with cloning and genetic tampering, he may be the one who “triggered” Peter’s transformation in Brand New Day. This would shift the franchise into a more scientific, horror-leaning direction, departing from the multiversal spectacle of the previous trilogy.

How does The Punisher fit in?
Jon Bernthal’s Frank Castle is a “frenemy” to Peter in the 2026 film. While Spider-Man is dealing with his mutation, the Punisher is conducting a lethal “clean-up” of the crime syndicates taking advantage of the city’s chaos. Their conflict arises when Frank decides that the “Man-Spider” is a threat that
needs to be put down, leading to a visceral rooftop chase through New York.
Will Hulk lose control?
Bruce Banner’s appearance in Brand New Day is reportedly as a mentor, but the “Red Hulk” serum or the multiversal instability may cause “Smart Hulk” to fracture. If the savage Hulk returns in the middle of New York, it would create a disaster that forces the mutated Spider-Man and the Punisher to team up, proving that the city needs heroes even if they are currently “wanted” men.

Does the movie end on a “Big Cliffhanger”?
Reliable leakers suggest that Brand New Day does not have a happy ending. Peter may be cured of his mutation but left more alone than ever, potentially ending with him watching the first “Incursion” sky from a lonely rooftop. This would lead directly into Avengers: Doomsday, where Peter is forced to step up as a leader because he has nothing left to lose.

Will Mac Gargan finally get his Scorpion suit?
After Michael Mando’s tease in 2017, the 2026 film is finally expected to deliver the Scorpion. He is rumored to be a “government-funded” hunter equipped with a tail made from salvaged Chitauri or Stark technology, specifically designed to track and kill the “Spider-Menace” that the public has come to fear.
Is Tombstone the new Kingpin?

With Wilson Fisk running for Mayor (and eventually winning), he needs a proxy to handle the street-level violence. Lonnie Lincoln, aka Tombstone, is the perfect choice. His indestructible skin and cold demeanor make him a terrifying physical match for a Peter Parker who is already struggling with his failing powers and lack of resources.

Who hired Boomerang and Tarantula?
The inclusion of these “B-list” villains suggests a “Superior Foes” or “Sinister Syndicate” approach where multiple assassins are competing for a bounty on Spider-Man’s head. This bounty is likely funded by a mysterious corporate entity—perhaps a shell company for Doctor Doom or a revived Oscorp—looking to eliminate the city’s most persistent vigilante.

Is the symbiote goop still in play?
The piece of Venom left in the 616-universe is the ultimate “wild card.” If Peter’s mutation is actually being caused by the symbiote attempting to bond with him in his weakened state, it would provide a new MCU-spin on the classic Black Suit saga, making the suit a “parasite” that Peter must fight off while also battling his physical transformation.

What happened to the Celestials?
The statue of Tiamut in the Indian Ocean has been declared a “Neutral Zone” by the UN, but Brave New World reveals it is being illegally mined for its celestial marrow. This resource is the key to creating “Super Soldiers” without the original serum, leading to the creation of the Red Hulk and potentially setting up the “Celestial Judgment” mentioned at the end of Eternals.

Is Sharon Carter still a Skrull?
Secret Invasion left Sharon’s status ambiguous, but Thunderbolts is expected to clarify if the “Power Broker” was a Skrull infiltrator all along. If she was, the “Real” Sharon may be a prisoner on a Skrull ship or a deep-cover agent who has been working with Nick Fury in secret, providing him with intel on the corrupt US government.

Where is Hercules?
Hercules is the “ticking time bomb” of the cosmic MCU. Having been teased in 2022, his delay suggests he is being saved for a major event—possibly as a member of a “God Squad” or as a primary antagonist for Thor in a film that explores the “Twilight of the Gods” as the multiverse begins to collapse around them.
