How many heroes will die?

There’s a strange ritual that plays out before every big Marvel finale: fans open spreadsheets. Who has an expiring contract? Whose arc feels finished? Who hasn’t had a proper send-off yet? We do it because Marvel taught us to - because these films genuinely kill people, and we’ve been trained to brace ourselves. So let’s do the maths on Doomsday properly. No leak exists, but you can still put a credible number on this by studying how the Russo brothers actually operate. And the pattern says: two to four. Not a bloodbath.

The Russo maths

Start with the evidence, because the Russos directed the two biggest body-count films in franchise history and they follow a clear, repeatable logic.

Take Infinity War. On the surface it’s the most apocalyptic film Marvel ever made - it ends with half of all life in the universe crumbling to dust. But look closer: almost all of that carnage was spectacle, and it was reversed a year later in Endgame. The genuinely permanent losses in Infinity War were few: Heimdall, Loki, Gamora, Vision. The Snap devastated precisely because, on some level, you suspected it couldn’t last.

Endgame did the opposite. It killed a small number of characters, but made every one permanent and shattering: Black Widow sacrificing herself on Vormir, Tony Stark burning out to undo the Snap, old Steve Rogers riding quietly off into the past. Three losses - each earned, each final.

It helps to understand why they ration deaths so carefully. A hero’s death in these films isn’t a plot event; it’s a currency, and Marvel spends it deliberately. Natasha’s fall recontextualised her whole arc. Tony’s death was the emotional full stop on eleven years of storytelling. Each was placed to detonate at a precise moment, for a precise character. That’s not a studio that kills at random - it’s one that treats every funeral as a scene it has to earn.

The likely spread

Doomsday is the setup film, the Infinity War of this pairing. So expect it to lean toward shocking, possibly-reversible losses up front, and to hold the truly permanent tally for Secret Wars the following year. Reading that pattern onto this film, a realistic spread looks like:

• One permanent, emotional death - the torch-passing gut-punch everyone is still discussing on the drive home.
• One or two ambiguous falls - cliffhangers the finale can revisit, undo, or confirm.
• Plenty of peril that resolves without a funeral - the near-misses and last-second saves that make a blockbuster feel dangerous without emptying the roster.

It’s also worth naming the pressure the film is under. Doomsday has to make Doom feel like a credible successor to Thanos - and Thanos earned his menace by winning, by actually taking beloved characters away and making it stick for a year. Doom needs an equivalent statement of intent. One or two well-chosen, well-staged deaths in the first act do that work instantly: they tell the audience the gloves are off and nobody is plot-armoured. That’s the real function of a Doomsday body count - not spectacle for its own sake, but a promise that the stakes in Secret Wars will be paid in full.

Watch, too, for the quieter kind of death: the torch-pass. Marvel loves to kill a mentor to force a protege to step up - it’s how Yondu’s sacrifice crystallised Star-Lord, how Tony’s death handed the future to a generation of kids who idolised him. In a film explicitly about a generational hand-off, expect at least one loss engineered specifically to elevate someone new. That death won’t just remove a character; it will promote another.

Why not more

Why not simply go bigger? Because a death is only worth what the film makes you feel, and feeling doesn’t scale with volume. Kill twenty heroes in a montage and the audience goes numb; kill one at the right beat and the cinema falls silent. Marvel also, bluntly, needs survivors - the entire point of this transition is to hand the MCU to the Fantastic Four, the X-Men and Sam Wilson’s Cap, and you can’t do that with an empty bench. And because Doomsday is drowning in variants and incursions, it has a uniquely convenient escape hatch: it can remove characters by rewriting reality, no death certificate required.

Our call: possible - pencil in two to four. Enough to prove Doom is genuinely lethal and that no one is safe; not so many that the saga staggers into its finale with nobody left to root for. Treat any online “confirmed death list” with deep suspicion - there are no real leaks, only educated guesses like this one. For the shortlist of who’s most exposed, see who dies in Avengers: Doomsday; for the villain doing the killing, will Doom kill the Avengers.
