Avengers: Doomsday

Who is Doctor Doom?

Victor von Doom debuted in 1962 in Fantastic Four #5 and is considered the greatest villain Marvel ever created. He is monarch of the small Eastern European state of Latveria, a genius on eye level with Reed Richards — and at the same time one of the most powerful sorcerers of the Marvel universe. Science, magic and an absolute claim to power in one person: that is what makes him unique.

His core motive: Doom is convinced the world would be better under his rule — and the frightening part is that in the comics he is occasionally proven right. He is not a destroyer like Thanos but a would-be savior with a boundless ego, who wanted to free his mother from hell and blames Reed Richards for his scarred face.

The Kang crisis and the great pivot

This film was originally called “Avengers: The Kang Dynasty”. Kang the Conqueror (Jonathan Majors) had been built up as the saga villain since Loki season 1 — including the Council of Kangs in Quantumania. After Majors' conviction, Marvel parted ways with him in December 2023, and the saga needed a new center.

At Comic-Con in July 2024 came the historic moment: the Russos return, the film is called Doomsday — and under the mask is Robert Downey Jr. Marvel replaced the failed plan not with a stopgap but with the biggest character still left, played by the face of the MCU itself.

Sacred Timeline, TVA and variants

Loki season 1 established the rules: there was a Multiversal War between countless timelines. A Kang variant (“He Who Remains”) ended it by pruning everything down to a single Sacred Timeline, guarded by the TVA. Sylvie's regicide reopened the jungle of branches — the multiverse has been sprawling uncontrolled ever since.

In season 2, Loki sacrifices himself and becomes the God of Stories: at the end of time he holds all timelines together with his own hands, like a living tree. Remember that — it is the most important open Chekhov's gun of the saga.

Incursions — when universes collide

Multiverse of Madness delivered the term that drives Doomsday: an incursion is the collision of two universes in which one or both are completely destroyed — triggered when the borders between worlds are violated too often.

We have already seen one: Strange visits a collapsing universe in ruins, and at the end Clea picks him up to repair an incursion “that you caused”. In the comics, incursions are the direct trigger of Secret Wars — the downfall of all worlds, from whose wreckage Doom forges his Battleworld.

Secret Wars: the blueprint

Two comic templates carry the name: the original Secret Wars (1984) — and Jonathan Hickman's Secret Wars (2015), the actual model. There the multiverse dies through incursions, and at the last moment Doom seizes the power of the Beyonders.

He creates Battleworld: a patchwork planet made from the remains of destroyed universes, which he rules as God Emperor Doom — with a rewritten reality in which nobody remembers the old world. Only a handful of survivors stand against him, first among them Reed Richards. If Doomsday follows this structure even roughly, we know where the journey is headed.

Franklin Richards — the most powerful child of the multiverse

The post-credit scene of First Steps is the direct entry into Doomsday: four years later, Sue finds little Franklin with a figure in a green cloak and metal mask — Doom kneels before the boy. In the comics, Franklin is an omega-level reality shaper who can create entire universes — and in Hickman's Secret Wars his power keeps Doom's Battleworld alive.

If the MCU follows that, Franklin is not simply a child in danger. He is the battery Doom wants to play god with.

Anchor beings, Earth-838 and the Fox legacy

Deadpool & Wolverine explained two decisive concepts: every universe has an anchor being whose death makes the whole timeline die — and the old Fox universe exists as its own branch in the MCU multiverse, including the Void as a dump for discarded characters.

Add Earth-838 with its Illuminati and Beast's post-credit appearance in The Marvels. The walls between the Fox past and the MCU present have long been riddled with holes — Doomsday only has to tear them down. That is exactly what half the cast is there for.

What else is on the board

Sentry & Void: the MCU has a world-destroyer-level being on the New Avengers' team — unstable, traumatized, and exactly the kind of weapon that gets fought over in a multiverse war.

Mephisto: Sacha Baron Cohen has been established as Marvel's devil since Ironheart — a deal-maker who becomes a heavyweight of his own in the long run.

The Council of Kangs: never resolved. Thousands of Kang variants are theoretically still waiting — and in the comics it is Doom who cleans up what Kang never finishes.

Wiccan: Billy Maximoff lives (Agatha All Along) — Wanda's son is a reality mage, and half the Young Avengers founding roster is complete with him.

Latveria — the country soon to be on every map

In the comics, Latveria is a small Eastern European state between Romania, Serbia and Hungary: picturesque villages, Doombots as police, zero crime, zero freedom. The trick that separates Doom from every other villain: he is a head of state with diplomatic immunity. You cannot simply arrest him — under international law, any attack on Doom is an attack on his country.

For Doomsday that means: the Avengers get an opponent against whom fist justice triggers diplomatic crises. And his people? Mostly genuinely love him — Latveria has no poverty, no wars, no elections. The most uncomfortable question the comics have asked for 60 years: what if the tyrant delivers?

The road map to the finale

This is the track ahead of us: Doomsday (December 2026) opens the two-parter — by everything structure and comics suggest, with an ending that hurts. In between lies a year Marvel will presumably fill with targeted series, before Secret Wars (December 2027) ends the saga and reshuffles the deck: a unified timeline, mutants included, an X-Men reboot behind it.

The mnemonic for everything released until then: if it is about variants, incursions, anchor beings or Franklin, it is required material. The rest is optional. This dossier keeps sorting that — and is updated after every trailer.
