If Loki's Branches Are All Real Now, the Snapped Heroes Might Still Be Out There

Doom's Hall H backstory is described in two words: 'stolen lives.' Most fans read that as a metaphor. This theory asks what happens if it's literal.

Two words from the San Diego Comic-Con 2026 Hall H reel have been sitting with fans longer than almost anything else out of the Avengers: Doomsday panel: 'stolen lives.' That's how Sue Storm's narration describes Doctor Doom's backstory, and most reactions since have treated it as atmosphere — a moody, vague phrase for a villain reel. What if it isn't vague at all, and it's describing something closer to literal theft, made possible by exactly what Loki left behind when he restructured the multiverse?

What's real and what's theory. REAL: Sue Storm's Hall H narration describes a 'stolen lives' backstory for Doom — that specific phrase is confirmed, its meaning is not. Loki restructuring the fractured multiverse into a single connected structure, Yggdrasil, holding every branch together himself, is also confirmed, on-screen canon from his show's season 2 finale. THEORY: that those branches becoming permanently connected under one steward means they're newly reachable in a way they weren't before, and that Doom's 'stolen lives' means literally taking something — power, a person, a version of someone — out of one of them. None of that is confirmed by Marvel.

What "Stolen Lives" Actually Refers To, On Screen

Stripped of speculation, here's the entire confirmed record: Sue Storm narrates a backstory for Doom during the Hall H reel that includes the phrase 'stolen lives.' That's it. No further detail, no images explicitly tied to the line, no character named. Everything after this point is this article reading that phrase against a separate confirmed fact about how the multiverse itself currently works — and building a bridge between them that Marvel has not built on the record.

The Branches Loki Didn't Erase

Here's the fact that makes the literal reading possible at all. He Who Remains' Temporal Loom offered exactly two settings: one Sacred Timeline, policed and pruned, or total erasure of every branch the instant he lost control. Loki refused both. He held every branch together instead — meaning every version of every event that had ever split off still exists somewhere inside Yggdrasil, unerased, just reorganized. That includes, as pure extrapolation from what 'every branch' has to mean, branches where the Snap in Avengers: Endgame went differently, was reversed sooner, or simply never happened to specific people at all.

What "Newly Adjacent" Could Mean

Restructuring isn't the same as leaving things alone — this site's companion theory on what Loki's stewardship might have cost Asgard makes a parallel argument about the price of that reorganization. Applied here: if Yggdrasil pulled once-distant branches into closer relation to each other and to the main timeline, then branches that used to be functionally unreachable — sealed off by TVA pruning, or simply too far removed to matter — could now sit right next door. Not open doors. Just, for the first time, doors that exist at all.

A branch you can't reach isn't really lost. It's just filed somewhere nobody's opened the drawer yet.

A Villain Who Doesn't Need New Powers, Just a Door

This is the theory's actual claim, stated plainly: Doom doesn't need to invent anything new to become dangerous. He needs one working method of reaching into a branch adjacent to his own and taking something out of it — a resource, a piece of power, a person who in his home branch is gone but who, somewhere in Yggdrasil, never stopped existing. 'Stolen lives,' read this way, isn't a metaphor for trauma. It's a description of a mechanism: lives that were lost in one branch, and are not lost in another, being taken from the branch where they're still being lived.

Which Heroes, Theoretically

This is deliberately where this article stops guessing at specifics. It would be easy, and cheap, to start naming which snapped or lost Avengers might theoretically exist in some untouched branch — that's a casting rumor, not a theory, and nothing here should be read as predicting a specific return. What's worth saying instead is the mechanic itself lines up with something Marvel has already shown it's willing to do: Spider-Man: No Way Home and the wider multiverse era have established that variants of people fans assumed were gone for good can exist elsewhere, untouched by whatever happened on the main branch. This theory just relocates that same mechanic from 'story device' to 'the actual thing Doom is doing to build his power base.'

Why the Throne Room Mural Would Land Differently

One more confirmed detail worth sitting with: Doom's throne room in the Hall H reel includes a family mural. On its own, that's scene-setting — a tyrant with a dynasty. Under this theory, it reads heavier. A mural isn't necessarily a record of people who were always his. It could just as easily be a record of people he added to that definition later, from somewhere else, however that's eventually explained on screen. That's speculation stacked on speculation, and it's presented here exactly that plainly — a visual detail this theory chooses to notice, not evidence of anything.

What Would Confirm or Kill This Theory

  • Confirms it: Avengers: Doomsday shows Doom, on screen, reaching into or drawing power from a branch that isn't his own point of origin.
  • Confirms it: any character presumed lost to the Snap or otherwise gone reappears from what's explicitly framed as a different branch, not a resurrection.
  • Confirms it: dialogue directly ties the phrase 'stolen lives' to specific people rather than leaving it as an emotional gesture.
  • Kills it: 'stolen lives' turns out to be entirely metaphorical — grief, guilt, or a title with no literal mechanic behind it.
  • Kills it: Doom's power is explained through an origin fully contained within his own branch, with no multiverse-reaching involved at all.

None of this is a prediction that any specific hero is coming back. It's a read on one phrase, held up against one confirmed fact about how permeable the multiverse now is because of what Loki chose not to erase. Whether Doom actually walks through that door, or whether 'stolen lives' just means something sadder and more ordinary, is exactly the kind of question Avengers: Doomsday hasn't answered yet.

Frequently asked

Is it confirmed that snapped heroes return in Avengers: Doomsday?
No. Nothing has been confirmed about specific characters returning through this mechanism. This is a theory about what Doom's confirmed 'stolen lives' backstory phrase could mechanically mean, not a casting prediction.
What is actually confirmed about Doom's 'stolen lives' backstory?
Only that the phrase itself was used in Sue Storm's narration during the SDCC 2026 Hall H reel. Marvel has not clarified whose lives, how they were stolen, or what it means for the plot.
Does Loki holding the multiverse together mean every branch still exists?
That's the show's own framing, yes. Loki explicitly rejects the choice between one Sacred Timeline and total erasure, choosing instead to hold every branch together as Yggdrasil. This theory extrapolates from that scope to argue branches with different outcomes from Endgame's Snap would still exist somewhere within it.
Is this the same theory as the one where Doom takes Loki's own power?
No. That's a separate, previously covered theory on this site about a direct confrontation between Doom and Loki. This theory doesn't require Doom and Loki to interact at all — it's about Doom reaching into other branches, not into Loki himself.
Why doesn't this article name which specific heroes might be involved?
Because that would cross from theory into an unfounded casting rumor. The mechanism is speculative enough on its own; naming specific returning characters isn't supported by anything Marvel has confirmed and isn't the point of this article.
