What might happen
Will Doctor Doom kill the Avengers?
Will Doctor Doom kill the Avengers in Avengers: Doomsday? We weigh the confirmed setup, the Russos' body count history and the comics to rate how likely a hero massacre really is.

Count on it - some of them. Marvel is collapsing four universes into one and needs to clear the board, and the Russos have killed major heroes in every Avengers finale. A total wipeout, though, is off the table.
There’s a moment in the Doomsday trailer that should worry you. Thor - a god who has stared down Thanos, watched his home planet burn, and lost nearly everyone he has ever loved - looks into the middle distance and admits that this new enemy frightens him far less than anything he has faced before. Then he quietly prays over his young daughter’s safety ahead of “one more battle.” Marvel does not write speeches like that for a villain who lets everyone walk home. So let’s not dance around it: Doctor Doom is going to kill Avengers. The only real question is how many.
A villain who already has a body count
If you only know Doom from the outside - the mask, the cape, the theatrical Latverian menace - it’s easy to underrate him. Comic readers know better. Across sixty years of stories, Victor von Doom has done things that would make lesser villains flinch. He traded his own first love’s soul to a demon in exchange for power. He has beaten the Fantastic Four bloody inside their own home, stolen the abilities of gods, and, in the comic that this film is named after, murdered the near-omnipotent beings who created him simply to take their thrones. Doom doesn’t kill for sport. He kills because someone had the nerve to stand between him and something he’d already decided was rightfully his.
And Marvel has told you, in its own marketing, exactly how large that appetite is this time. The official logline calls Doom an “existential threat” - not to a city, not to a nation, but to reality itself. When the threat is drawn that big, the heroes lined up against it are, by definition, expendable.
The machinery demands sacrifice
Now feed that ruthlessness into the machinery of this particular film. Doomsday is violently smashing four separate realities together, and Marvel plainly intends to walk out the far side with one tidy, streamlined universe. A collision that big does not happen without casualties. And the Russo brothers - the directors handed the keys - have never made an Avengers film that let its heroes off clean. Infinity War ended with the Snap and half of all life turned to ash. Endgame took Iron Man and Black Widow, permanently. A bloodless Doomsday would break the brothers’ entire rhythm and make a mockery of that Thor speech. Casting Robert Downey Jr. as the villain only tightens the screw: you do not spend your single most valuable, most beloved actor on a Doom who folds politely.
Why it still won’t be a total massacre
So why not just kill everyone? Because carnage without restraint means nothing. Marvel has learned, sometimes painfully, that a death only lands when it’s given room to breathe. Kill twenty heroes in a blur and the audience feels numb; kill one at exactly the right moment and a cinema full of grown adults goes silent. Doom will thin the ranks, not empty them.
There’s also the small matter of the future. Sam Wilson’s Captain America, Shang-Chi, the Fantastic Four - these are the faces Marvel has spent years and hundreds of millions of dollars building to lead the next decade. Slaughtering them now would be corporate self-sabotage. And because this is a story stitched from variants and incursions, “dead” comes with an asterisk; some fatalities here may prove to be cliffhangers that Secret Wars quietly rewrites.
That points the knife at a specific group. The safest heroes are the shiny new leads. The most exposed are the visiting legacy characters - the classic X-Men on loan from a dying reality, an older Steve Rogers dragged out of a peaceful retirement - and the veterans whose arcs already feel finished. We name the likeliest casualties in who dies in Avengers: Doomsday and run the numbers in how many heroes will die.
Everything about the film’s marketing has been engineered to make you feel this coming. The teasers didn’t sell spectacle so much as fear - Thor’s prayer, the grim faces, heroes bracing rather than boasting. That’s a deliberate tonal choice. Marvel has spent over a year conditioning the audience to walk into the cinema already worried about who won’t walk out, and studios don’t spend that much marketing capital building dread unless they fully intend to cash it in.
So don’t walk in expecting everyone to make it home. Walk in expecting Doom to make an example of someone early - brutally and deliberately, to prove there’s no bargaining with him - and expect that first loss to set the terrified tone for everything that follows.
Our call: likely - for some of them. Expect Doom to take at least one or two headline Avengers off the board early and brutally, precisely to prove that there is no reasoning with him and no plan that holds. Then expect a battered, grieving survivors’ bench to limp toward the finale. The film wants you frightened for these people. You should be.
