Did Strange's Multiverse Spell Pull Doctor Doom to Earth-616?

The Sky Over Liberty Island Screamed Incursion Before the MCU Had a Word For It

Long before Doctor Strange in the Multiverse of Madness gave Marvel fans a name for universes crashing into each other, Peter Parker and Doctor Strange handed audiences the image anyway. Picture it again: the sky above Liberty Island splitting into glowing orange fault lines, villains dropping out of thin air mid-sentence, reality itself looking like a windshield about to give way. At the time, in December 2021, it read as an epic finale and nothing more. Looking back with a full incursion vocabulary now in hand, it reads like something else entirely, arguably one of the most visually incursion-coded images the MCU had shown up to that point, years before the franchise ever put that word on screen.

This is where a speculative theory starts, and it needs to be labeled as exactly that from the first sentence: pure speculation, nothing confirmed by Marvel Studios, no trailer or press release backing any of it up. But the pieces are sitting in plain sight, and it is worth asking the question out loud anyway. Did the corrupted spell that tore open the sky during Spider-Man: No Way Home leave behind exactly the kind of wound that later mythology calls an incursion, and is there any real chance that wound is the reason Doctor Doom's presence eventually finds its way into Earth-616? Nobody outside Marvel Studios knows the answer. That has never stopped a good theory from being fun to chase.

What Strange's Spell Actually Did (and How Peter Wrecked It)

The mechanics are worth walking through carefully, because the entire theory hinges on them. After Peter Parker's identity is broadcast to the entire planet, he asks Doctor Strange for a way out: a spell that makes the world forget he is Spider-Man. Strange agrees, reluctantly, and begins casting something enormous, a spell built to rewrite global memory in one clean motion, contained and controlled from start to finish.

Except Peter cannot leave it alone. He keeps interrupting mid-incantation, first to protect MJ, then Ned, then his aunt, piling on exceptions while Strange is holding a half-formed spell together with his bare hands. The spell does not break cleanly. It corrupts, leaks, and eventually rips loose entirely, and instead of quietly rewriting memory, it starts pulling in every person from other universes who knows Peter Parker is Spider-Man. That is how Green Goblin, Doctor Octopus, Electro, Sandman, and the Lizard all end up standing in Peter's world, confused and, in most cases, extremely hostile. For a full scene-by-scene walkthrough of how that chaos eventually resolves, our breakdown of the No Way Home ending goes through it beat by beat.

The visual capstone of all that corruption is the Statue of Liberty battle, fought under a sky that has been visibly torn open, glowing and unstable, as if the atmosphere itself were a piece of fabric with a hole ripped straight through it. Once the fight is won, Strange does not just patch the damage and move on. He casts a second spell, a complete and uncorrupted one this time, that erases every memory of Peter Parker from every mind on Earth, himself included. The film frames this explicitly as the fix, the thing that reseals the damage and puts the multiverse's walls back where they are supposed to be. The villains pulled in from other universes during that corrupted casting include a small, specific list worth keeping straight:

• The Green Goblin, Norman Osborn's alternate-universe tormentor
• Doctor Octopus, Otto Octavius fused with his mechanical arms
• Electro, supercharged and hunting for a bigger power source
• Sandman, a shapeshifting mass of animated grit and stone
• The Lizard, Curt Connors trapped inside his reptilian alter ego

Incursions, Explained: Why Uncontrolled Multiverse Magic Is the Named Culprit

"Incursion" did not exist as MCU vocabulary until Doctor Strange in the Multiverse of Madness arrived in theaters in May 2022, five months after No Way Home closed its own multiversal mess. The concept, once introduced, is blunt: when two separate universes make contact, something has to give. One collapses, or both do, unless the contact point is severed fast enough to stop it. Our own incursions explainer has covered how the film frames repeated multiversal travel and reckless spellwork as the two biggest accelerants, the kind of dimensional traffic that wears down the walls between realities until they simply cannot hold anymore.

That framing matters here, because Doctor Strange in the Multiverse of Madness never treats incursions as some vague cosmic accident. It ties them directly to specific, named actions: Wanda Maximoff dream-walking across universes in search of her children, the Illuminati of Earth-838 experimenting with universe-to-universe travel, Strange himself using forbidden magic to hop between dimensions when he runs out of better options. Our deep dive on the Earth-838 Illuminati lays out exactly how much risk that council was willing to take just to keep their own reality stable. Uncontrolled multiverse magic, in other words, is not a footnote in this mythology. It is the named cause, stated plainly, more than once, on screen.

The Theory: Did Doom Slip Through the No Way Home Rupture?

Here is the speculative leap, stated as plainly and as clearly flagged as possible: this is a Tier 3 fan theory, unconfirmed, and not supported by anything Marvel Studios has said on the record. But look again at what No Way Home actually put on screen. A spell corrupted mid-cast. A visible, glowing tear stretched across the sky. Multiple universes making direct, sustained contact during an extended battle sequence. On its own, none of that proves anything about incursions, since the film never uses that language. But it lines up closely enough with the checklist Multiverse of Madness would lay out five months later that the coincidence is hard to ignore entirely.

Layer onto that the fact that Robert Downey Jr. is confirmed to play Doctor Doom in Avengers: Doomsday, a film reportedly built around heroes from three distinct universes on a collision course, and the timing becomes tempting to connect. What if the rupture over Liberty Island never fully closed the way the film wants viewers to believe? What if it left behind a hairline crack in the wall between realities, one that stayed quiet and dormant for years before something, or someone, found it and pushed through? It is a tidy, spooky idea. It is also, to repeat, entirely speculative.

To be exceptionally clear, nothing in Avengers: Doomsday's marketing has referenced No Way Home's spell as an incursion trigger. Not a trailer, not a poster, not a single on-record line from a producer or director. This is a connection the theory draws on its own, based on thematic and visual similarity rather than any confirmed plot detail. It is exactly the kind of pattern-matching fan theories are built on: fun to chase, worth writing down, and not something anyone should mistake for a leak or a genuine spoiler.

Perhaps every spell that tears a hole in reality leaves a scar behind, and scars do not always heal the way we are told they do.

Timeline: What No Way Home Showed vs. What Multiverse of Madness Later Defined

Laying the two films side by side makes the pattern easier to see, and honestly, easier to question too. Below is how the visual evidence from December 2021 compares with the formal rules Marvel Studios introduced five months later.

The overlap is loose, but it is real. Both stories describe multiverse contact triggered by uncontrolled magic rather than any planned, sanctioned crossing. Both show visible, sky-level damage as the warning sign that something has gone wrong. The differences matter just as much, and they are the strongest reason to stay skeptical: No Way Home never uses incursion language, and its rupture is explicitly shown closing on screen rather than being left open. Still, five months is a short gap for one movie's mechanics to accidentally rhyme this closely with the rules the next movie lays out, which is exactly why the theory keeps circulating.

The Counter-Argument: Strange's Second Spell Was Built to Close the Door

Fairness requires sitting with the strongest objection, and it is a genuinely strong one. The entire climax of No Way Home's ending is built around Doctor Strange casting a full, corrected spell specifically to undo the damage his corrupted first attempt caused. The film does not leave that ambiguous. It shows the tear closing, shows the world's memory rewritten cleanly, and frames the entire sequence as a wound getting stitched shut, not one that keeps quietly bleeding in the background for five years.

If the rupture really was resealed the way the film presents it, there is no obvious open door left for anything, let alone Doctor Doom, to wander through later on. Incursions in the mythology this site has already covered tend to come from active, ongoing multiversal contact, not from a scar that closed cleanly on screen years before the fact. That is a real problem for this theory, and it should not get waved away just because the visuals happen to line up in hindsight.

There is also the simple matter of evidence, or the lack of it. Nothing about Avengers: Doomsday's marketing, casting announcements, or plot teases has connected Doom to a Spider-Man movie from 2021. The "three distinct universes" description attached to the film points toward its own new mythology, not backward toward a spell Peter Parker begged Strange to cast. Until Marvel Studios says otherwise, that is the honest state of the evidence: an intriguing coincidence, not a confirmed connection of any kind.

What This Means Heading Into Avengers: Doomsday

None of this is meant to land as a prediction, and it should not be read as one. It is a Tier 3 theory, speculation stacked on speculation, built from two films that happen to rhyme in ways that are fun to notice and effectively impossible to prove from the outside looking in. The visual language of a torn sky, the mechanism of a corrupted spell, the timing of a villain reveal that arrived years later: all of it fits together neatly enough to make the theory worth writing down, and loosely enough that it could just as easily amount to nothing at all.

What is actually confirmed is simpler, and in its own way, more exciting than any single fan theory. Doctor Doom, played by Robert Downey Jr., is coming to Earth-616 in Avengers: Doomsday on December 18, 2026, in a story our breakdown of the three distinct universes colliding in that film lays out in far more detail. Whether his path in ever crosses back through a five-year-old Spider-Man spell, or arrives by some entirely new mechanism the marketing has not revealed yet, audiences will not have to wait much longer to find out. Mark the date, keep an eye on the sky, and see whether Marvel Studios ever decides to connect these particular dots on purpose.
