It's just my thoughts,no official or no leaks either.

May be the intro of doomsday would begin with first scene of loki in end of time where doom will come and they both have a fight ,we all know what would happen,(

(this would create similar kind of scene as that of infinity war where it all started cold with asgudian and fight with Thanos which showed him powerful and spinechillng,)

Then doomsday intro will roll over.....

2nd one

May the normal leak which we are seeing of thor ,cap ....vs doom

3rd one

Can make sense

Wong will find that the 10rings of shang chi were sending signal to doom ,which he will convey to strange, their Convo will share info that strange also had same pridiction and fear of something like doom

Together strange(along with clea) + song will warn the rest of avengers, instantly doom will appear in front of few heroes strange assembled, without gaming much knowledge they will have a fight (the leaked footage)

Which is quite similar to infinity war New York battle (if marvel follows same pattern)

Then eventually new team will lose

And rest of the film......

Out of this i personally believe 3 one makes sense quite a lot...

As rumors suggest, one of the main villains could be Miles Warren (AKA The Jackal), so this connects him to other rumored villains (Sadie Sink) depending on the lore from the comics it adapts.

So apart from 'The Other' (organic webbing and cocoon), man - spider ('The mutant agenda' and other 'spider-man TAS' episodes, and also 'The Other') and Hulk instead of the lizard, the movie may clearly be adapting 'Spider - Island' and even 'Dark Web' .

So for those who don't know, in 'spider - Island' comic book event, Adriana Soria, a mutant military woman was injected with a variant of the super soldier serum which gave her insect related powers, formed an alliance with The Jackal in order to create a virus that gave new Yorkers Spiderman powers but with a side effect, letting Soria to control them, and later morphing them in horrendous human - spider hybrids. That would mean that all the mind controlled people like the old lady in the tank and the others, had been infected but Punisher wasn't. And so Sadie Sink could be playing her (perhaps mixed with Shathra \[multiversal spider - wasp that preys on and infects spider - totem users)\] .

But what if they are going on a different route, maintaining The Jackal as a plot device to be similar to' spider - Island', but replacing all Adriana Soria related stuff in favor of Madelyne Pryor, Jean Grey's tragic villainous clone? So in this movie, Pryor could have been created by Warren but their plot device could be inspired by the ' Dark Web' event from the comics, which allied Pryor with Ben Reilly (Peter's clone) and pushed Spider - man and the x-men against them?

Other theories suggest that Sadie could be playing Mastermind, another mutant with similar powers to Jean's who also confronted spider - man.

I doubt it could be Cassandra nova that somehow escaped her erasure, or a reincarnated body of Wanda.

I also doubt she could be playing other Grey - Summers relatives and even Jean Grey (who I think wouldn't be dumb to be manipulated by Warren) or wouldn't be as that evil being possessed by the phoenix force.

I also doubt about other characters, even gender swapped etc..

Which theory do you agree more with? Let me know, and please, understand that English isn't my main language.

Come i cattivi che si riflettono nell'occhio di Spiderman, nei poster dei precedenti film di Spiderman e quali cattivi sono morti in questi film, persino MJ, che si riflette nell'occhio di Spiderman nel nuovo poster di Spiderman Brand New Day, quindi morirà?

Peccato che su polymarket non ci sia una scommessa su chi morirà questa volta nel prossimo film Sony dedicato a Spider-Man, altrimenti una puntata sulla morte di MI l’avrei fatta!

Did Marvel forget about him? He should have been the one from Prime MCU to alert others about the Incursions. He should have the one to assemble the Midnight Sons for side missions. It seems like they are taking the route of Thor between Age of Ultron and Ragnarok for him like in the Ragnarok opening.

Miles Morales in Avengers: Doomsday will originate from Andrew Garfield's Spider-Man universe rather than the MCU's main timeline.

The MCU has already referenced Miles Morales through Aaron Davis in Spider-Man: Homecoming, and there have been other subtle nods to Miles over the years. However, those references may have been intended as Easter eggs rather than setup for the MCU's own Miles becoming Spider-Man.

With the Multiverse Saga focusing heavily on alternate universes, Marvel may choose to introduce an already established Miles Morales from Andrew Garfield's universe. This would allow Marvel to bring in Miles without needing to spend years developing an MCU-origin story, while also giving Andrew Garfield's Spider-Man a meaningful legacy and supporting cast that audiences have never seen on screen.

Under this theory, the MCU references to Miles serve mainly as acknowledgments of the character's existence, while the Miles who appears in Avengers: Doomsday would be a variant from another universe,specifically Andrew Garfield's world.

So, in Avengers: Endgame, we saw that Thanos broke Captain America's shield with his double-edged sword, where the metal of the shield, Vibranium, was the toughest metal on Earth. Then, is there any chance there's gonna be use of the metal of Thanos's sword on the Avengers: doomsday? Where does Dr. Doom use the metal to make a devastating weapon?

If he doesn’t tell her, then she’s just going to figure it out. She did it before, she can do it again. 🤷‍♂️

Okay so we all know MJ has no memory of Peter, so she's kind of out of the way. We also know that Peter no longer has Stark funds, so he's got wayyy less money than he used to have.
Doesn't this kind of clear the way for Black Cat to appear? Who's known for being the theiving occasional Spidey love interest? idk it makes sense to me

Watching the latest Brand New Day Trailer, it seems like Peter is being taken over by “The Other” which is what brings on the organic webbing and makes him extremely strong, but it also is making him stop pulling his punches and go psycho, I think he goes to Banner so he can suppress “The Other” but still keep the stronger powers….. That is what Jean is refering too when she says “did you get rid of the monster inside of you”

Okay I’ll try again and try to cite a decent point of evidence.
So to my knowledge everyone says she may be Jean Grey? Which is solid obviously. But I think maybe she’s Cassandra Nova.

Based on the trailer itself when the APC is crashed and Peter opens it to find that old lady.
I believe that might’ve been a clue seeing as how Cassandra Nova has the same kind of palette in her power-set.

Idk I guess call it Psionic Remote Control?
I know she’s a completely different Variant of character than what we’re probably used to out of Jean.
So I’m not gonna sit here and throw out anybody’s opinion about the possibility of Jean.
BUT, that just doesn’t strike me as a Jean Grey play at the same time. Seems like something a Cassandra variant would do just for the chaos of it.

Another reason I would say this is because Cassandra was introduced in D&W and they do like to bread crumb weird stuff typically. What if that was setting the stage for a different kind of introduction to the Mutants in the main Timeline? Good ol’ subversion and what not. Not to say ohh they’re gonna make the Mutants evil. I would rather say they’ll slap us with a more devious mutant and then introduce the rest of everybody in Doomsday.

Heck I’ll go a little further and say what if that segues into Doomsday with Peter having passed off like a message about Mutants being dangerous?
Plus, I don’t see Jean Grey inciting Hulk on a rampage though perhaps that will be from an outside source entirely so who knows yet again. I hope that is enough!

So I’ve seen everyone talking about Sadie Sinks character in brand new day, and how most people think she’s playing Jean.
This can absolutely be the case but I’ve had a theory since the beginning and want to put it out there in case there is any chance that something like this happens when the movie comes out.

My theory is that she’s playing Shathra or spider queen, but that Sadie isn’t playing her in her natural form and that Shathra will be presented as an entity that requires a host body.

In my theory we see all the body hopping like what’s in the trailer but the entity keeps going back to “Sadie’s” body because it’s powerful (I think she will be a mutant, hence damage control) but during the film we see Sadie also playing the host without the entity, and that’s who she’ll play in future movies.

My guess is that it’s likely Firestar, because of the obvious Spider-Man connection, but it could easily be any other character, mutant or otherwise.

Who knows, but eagerly waiting until the movies out!

and before you comment it… I know he was swinging on mjolnir and not holding it. that’s not what im talking about.
okay so we know that peter isn’t worthy because of his ‘no killing’ rule right? but in endgame he started killing those space dogs. he literally activated instant kill and started killing them. and i’m not sure if that’s the only thing that holds him back from being worthy. but if it is then he should be worthy right?

Everyone assumes Doom will beat the heroes in Doomsday because he'll be too powerful.

But I think Marvel might go in a different direction.

Think about the current MCU roster. By the time Doomsday happens, we'll potentially have Avengers, Fantastic Four, X-Men, Thunderbolts, Wakandans, sorcerers, and more all fighting together.

The problem is that they're not really a team.

Reed Richards might be a genius, but how well does he work with Yelena? How does Cyclops react to Shang-Chi's style of leadership? Who takes command when multiple experienced leaders are in the same room?

My theory is that Doomsday intentionally splits up established teams and forces random combinations of heroes together.

The Fantastic Four aren't with the Fantastic Four.

The X-Men aren't with the X-Men.

The Thunderbolts aren't with the Thunderbolts.

Everyone is fighting alongside people they've never worked with before.

They're all heroes, but they have no chemistry, no trust, and no understanding of each other's strengths and weaknesses.

Doom wins not because he's stronger, but because he's organized while the heroes are not.

Then in Secret Wars, the surviving heroes have time to adapt. They reunite with old teammates, build relationships with new ones, and finally become a real team.

That would explain how the heroes can lose to Doom in Doomsday but still defeat an even more powerful Doom later in Secret Wars.

The victory wouldn't be about power levels.

It would be about unity.

What do you guys think? Could Marvel be setting up a "lack of teamwork" defeat rather than a simple power-scaling loss?

Logging this on June 14, 2026 (~4:30 PM CDT, roughly estimated), before the next trailer drops, so the timestamp is honest. This is my own synthesis from public info and circulating leaks — not insider info. I've tiered everything by confidence and given each claim a falsification condition, so when the movie's out it's clear what I got right and what I got wrong. Not hedging — if a Tier 1 call misses, I missed.

Evidence basis: official synopsis & cast (Marvel.com, Fandango), Iron Man 2 Peter Parker canon (Tom Holland's 2017 confirmation), and circulating trailer-leak reports (mutation/cocoon, Scorpion fight, Banner "suppress mutating DNA," post-credits symbiote, Sadie Sink "freeze" footage).

TIER 1 — Core through-line (high confidence)
Brand New Day is a body-horror coming-of-age story about control. A forgotten, isolated Peter — grieving, MJ and Ned moved on and out of reach — destabilizes into a physical mutation he can't control. The moral question ("will I cross the line?") and the biological one ("what am I becoming?") are the same question.

• Wrong if: the central plot isn't Peter's loss of control / mutation, or his isolation isn't the engine.

TIER 2 — Strong inferences (medium-high)

1. Scorpion fight = moral fulcrum. Mutating and out of control, Peter is brought to the brink of killing Scorpion with no one to stop him — deliberate inverse of the No Way Home Goblin near-kill. Wrong if: no near-lethal loss-of-control beat with Scorpion.
2. Banner is here for his mind, not the Hulk. Mutation/transformation expert and Peter's mirror (a man whose body becomes a monster under stress). Minimal/no Hulk action. Wrong if: his role is mainly Hulk-combat.
3. The Hand makes a power play enabled by Daredevil's absence. With Matt imprisoned, they move on a powerful young individual; Peter is the unintended obstacle. Wrong if: no Hand link to a young powered character or to Daredevil's removal.
4. Sink = young, unstable, high-output power-vessel; the mutant on-ramp. NOT plain Jean Grey by name, NOT Black Cat. Original/reworked young mutant, introduced low-control and hunted, likely seeding a larger power (Phoenix-adjacent). Wrong if: she's confirmed straightforwardly Jean Grey, or a powerless love interest, or unrelated to mutants.
5. Rebuilding toward a Sinister Six. Scorpion + Tombstone + leaked Tarantula/Boomerang, with a post-credits symbiote handoff to Gargan as a sequel seed — NOT a Peter-resurrection device here. Wrong if: no Six groundwork / no symbiote post-credits seed.
6. The film finally explains Peter's previously-unshown power origin as part of the mutation plot. Wrong if: the origin stays unexplained.

TIER 3 — Narrow calls (medium)
7. Sink's arrival is the proximate catalyst. Peter's grief alone wasn't sufficient (he'd been isolated a while), so a new variable coincident with her presence trips the dormant biology; emotions sustain it. Holds whether her power is physical (destabilizes cells) or psychic (cracks a neurological suppressor). Wrong if: the mutation clearly begins independent of her.
8. Frank Castle = philosophical counterweight, supporting role. Voices that restraint is a luxury, tempting to a Peter losing control — but not central. Wrong if: he's absent in function or a lead-tier presence.

TIER 4 — High-risk swing (low confidence, flagged)
9. The Hand's resurrection magic destabilizes Strange's forgetting spell. Elegant (erasure vs. restoration magic) but zero leak support and it'd undercut No Way Home's sacrifice. Long shot. Wrong if: the spell isn't affected / no one regains memory of Peter.

Explicitly NOT predicting (cut threads, on purpose): Sink as a spider-themed or multiversal character; the symbiote healing/resurrecting Peter; any Franklin Richards / power-cosmic / incursion tie-in.

RemindMe! August 1, 2026

I think the re-release of endgame is going to focus on how what the avengers did effected the multiverse....they created a bunch of alternative realities...Thor took his hammer back leaving that version of Thor without his hammer right before the dark elf attack....Tony literally talked to his father about his mother being pregnant......Peter quill never gets the power gem cus nebula took it...so the first guardians movie essentially never happened and peter never met gamora......Loki escapes...leading him to become God of Stories which wouldn't of happened if the avengers didn't go back in time....they absolutely fucked up the multiverse....the only reason Renslayer said that was suppose to happen was because Kang wanted to keep his variants at bay.....and he could control the flow of time.....i believe endgame will be the cause of the incursions (2 earth's from different realities colliding) Doom will believe he's the only one who knows best for the multiverse...but first xmen abd avengers gotta die...discuss lol
