Loki’s Storyline Will Shape Avengers: Doomsday in a Major Way

How Loki Connects to Avengers: Doomsday

Marvel Studios’ Avengers: Doomsday is shaping up to be one of the most ambitious films in MCU history, and it now has a direct connection to Loki. The upcoming crossover will build upon the Disney+ series in more ways than Tom Hiddleston’s return. Writer Michael Waldron, the creative mind behind Loki, is co-writing the movie’s script, ensuring the multiverse foundation he built continues on the big screen.

Waldron made history as the first Disney+ writer to pen an Avengers film. His past work on Loki and Doctor Strange in the Multiverse of Madness has already tied closely into Deadpool & Wolverine, and now his TVA concepts will reportedly influence Avengers: Doomsday even further.

What Makes Michael Waldron’s Role So Important?

Despite early rumors that he had stepped away from the project, Waldron recently confirmed that he remains fully involved. Speaking to ScreenRant, he shared that he has been traveling “back and forth from London” while writing alongside veteran MCU writer Stephen McFeely.

This collaboration marks a major first for the Russo Brothers. In their past MCU projects, including Infinity War and Endgame, they exclusively worked with McFeely and Christopher Markus. Waldron’s addition expands that circle, bringing his expertise in multiverse storytelling into the Avengers’ world.

With Pedro Pascal already wrapping his scenes as Mr. Fantastic, production appears to be moving steadily toward its December 18, 2026 release.

What Role Could Loki Play in Avengers: Doomsday?

After his transformation into the God of Stories in Loki Season 2, Hiddleston’s character now oversees all timelines in the multiverse. This makes him a natural target for Robert Downey Jr.’s Doctor Doom, who reportedly seeks control over reality itself.

Loki’s position could set up a high-stakes clash between two brilliant minds—one trying to preserve order, the other seeking domination. It also opens the door for an emotional reunion with Thor, potentially giving fans one of the film’s most powerful moments since Infinity War.

As Loki becomes the guardian of the multiverse, the Avengers may rely on him not just as an ally but as the force keeping reality intact. Hiddleston has hinted that this version of Loki will be a “new” take on the character, shaped by wisdom, sacrifice, and an understanding of cosmic balance.

What This Means for the Future of the MCU?

By bridging Loki and Avengers: Doomsday, Marvel is tightening the threads of its multiverse saga. Waldron’s involvement ensures the TVA, timelines, and variant concepts will play an even larger role in shaping how Earth’s Mightiest Heroes confront Doctor Doom.

For fans, this connection promises a deeply emotional and intellectually layered Avengers story—one that combines myth, science, and destiny in a way only the God of Stories could inspire.
