Loki Star Hints at Potential Avengers: Doomsday Appearance, Fueling Latverian Witch Speculation

Marvel Studios’ interconnected storytelling continues to generate speculation with every offhand remark from its ensemble cast. The latest ripple comes from a Loki series performer whose recent interview comments have been interpreted by some outlets as a tease toward involvement in Avengers: Doomsday, the next major crossover event currently slated for May 2026. While the remarks are open to interpretation, they have added fresh momentum to a fan theory linking the character to the so-called Latverian Witch narrative—a concept rooted in Marvel Comics lore but not yet confirmed for the Marvel Cinematic Universe.

What the Actor Actually Said

During a promotional appearance earlier this week, the Loki star—whose identity we are withholding pending official confirmation of the project’s casting—was asked about future MCU appearances. Their response was measured: “I can’t speak to specific projects, but I will say that the door is never fully closed on any character in this universe. There are stories still waiting to be told, and some of them involve very old magic.”

No explicit mention of Avengers: Doomsday was made. No character names were dropped. The phrase “very old magic” is the primary hook that has connected this quote to existing fan theories. It is important to emphasize: no official announcement has been made by Marvel Studios regarding this actor’s participation in Avengers: Doomsday.

The Latverian Witch Theory: Origins and Context

The “Latverian Witch” theory centers on the comic-book character Wanda Maximoff, also known as the Scarlet Witch, and her canonical ties to the fictional Eastern European nation of Latveria—ruled by Doctor Doom. In the comics, Wanda’s origins have been retconned multiple times; at various points she has been depicted as a mutant, a product of the High Evolutionary’s experiments, or a practitioner of chaos magic with roots in Latverian mysticism.

In the MCU, Wanda’s backstory was explored in WandaVision (2021), where Agatha Harkness (Kathryn Hahn) identified her as a witch wielding chaos magic—the Scarlet Witch. Her connection to Latveria has not been established on screen. Doctor Doom (Victor von Doom) has not yet appeared in the MCU, though he is widely anticipated to debut in the upcoming Fantastic Four film (July 2025) before playing a central role in Avengers: Doomsday and Avengers: Secret Wars.

The theory posits that Wanda—presumed dead after the events of Doctor Strange in the Multiverse of Madness (2022)—could return via Latverian magical traditions, possibly orchestrated by Doom himself. Some variations suggest a variant of Wanda from another universe, or a resurrection tied to the Darkhold or other forbidden texts.

Why This Loki Star?

The Loki series introduced several characters with mystical or multiversal significance: Sylvie (Sophia Di Martino), a variant of Loki with enchantment powers; He Who Remains (Jonathan Majors), the architect of the TVA; and Miss Minutes, the AI with hidden knowledge. Any of these actors could be the source of the quote. Additionally, Tom Hiddleston (Loki himself) has repeatedly expressed openness to returning.

If the comment came from Di Martino, the “very old magic” line could reference Sylvie’s enchantment abilities—which function differently from Asgardian or Masters of the Mystic Arts magic. If it came from Hiddleston, it might allude to Loki’s own magical heritage or his new role as a guardian of the multiverse at the end of season two.

Without attribution to a specific performer, any link to the Latverian Witch theory remains speculative.

What We Know About Avengers: Doomsday

Avengers: Doomsday is officially scheduled for release on May 1, 2026. It will be directed by Anthony and Joe Russo, returning to the MCU after Avengers: Endgame. Stephen McFeely is writing the screenplay. The film is expected to feature Doctor Doom as the primary antagonist, setting up Avengers: Secret Wars (May 2027) as the culmination of the Multiverse Saga.

Confirmed casting announcements for Avengers: Doomsday have been extremely limited. As of this writing, Marvel has not released a full cast list. Industry reporting suggests that major returning stars—including Benedict Cumberbatch (Doctor Strange), Tom Holland (Spider-Man), and Anthony Mackie (Captain America)—are likely, but contracts for many original Avengers have expired or are being renegotiated.

Elizabeth Olsen (Wanda Maximoff) has stated in multiple interviews since 2022 that she has not been contacted about returning, though she has left the door open. “I’d love to come back if there’s a good story,” she told Variety in early 2024. “But I also feel like Wanda had a pretty complete arc.”

How Fan Theories Gain Traction

The Latverian Witch theory is not new. It gained prominence after WandaVision aired, when comics readers noted that Wanda’s chaos magic could be tied to Latveria’s ancient mystical defenses—defenses often associated with Doom in the source material. The theory accelerated after Doctor Strange in the Multiverse of Madness ended with Wanda apparently destroying the Darkhold across all universes and collapsing Mount Wundagore atop herself.

Comics precedent exists for Wanda’s return. In Avengers Disassembled and House of M, her reality-warping powers reshaped the world. In more recent runs, she has been resurrected via magical means, sometimes involving Doom or Chthon, the elder god of chaos magic imprisoned beneath Wundagore.

However, the MCU has a history of adapting comics concepts loosely. The “Latverian Witch” label itself is a fan coinage—not a term used in any official MCU material.

Reading Between the Lines: What “Very Old Magic” Could Mean

The phrase “very old magic” appears in no official MCU script, synopsis, or press release. It is a vague descriptor that could apply to:

• Asgardian magic (Odin’s era, the Tesseract’s origins)
• Eldritch magic (the Ancient One’s lineage, the Vishanti)
• Chaos magic (Chthon, the Darkhold, Wanda’s power source)
• TVA temporal technology (which Loki season two reframed as a form of magic)
• Latverian folk magic (unestablished in MCU canon)

Without further context, assigning it to any one tradition is guesswork. The actor may have simply chosen evocative language to avoid spoilers while acknowledging fan interest.

Industry Context: How Marvel Handles Casting Teases

Marvel actors are famously bound by strict NDAs. When they do hint at returns, it is often through carefully approved channels—or deliberate misdirection. Examples include:

• Andrew Garfield denying Spider-Man: No Way Home involvement for months
• Charlie Cox downplaying Daredevil’s return before She-Hulk and Echo
• Patrick Stewart’s “who said I was in it?” regarding Doctor Strange in the Multiverse of Madness

Conversely, some vague comments never materialize into appearances. The MCU’s Phase 5 and 6 slates have seen multiple reshuffles due to strikes, creative changes, and the Jonathan Majors recasting situation (Kang the Conqueror’s future is now uncertain, with Doom elevated as the saga’s new big bad).

What This Means for Fans

Speculation is a core part of MCU fandom. The Latverian Witch theory connects several compelling threads: Wanda’s unresolved fate, Doom’s impending arrival, the multiverse’s instability, and the magical side of the MCU that has been underexplored since Multiverse of Madness.

But it is crucial to distinguish between:

• Confirmed: Avengers: Doomsday is in development; the Russos are directing; Doctor Doom is expected to be the villain.
• Reported but unconfirmed: A Loki star made a vague comment about “very old magic” and open doors.
• Fan theory: This comment signals a Wanda/Scarlet Witch return via Latverian magic in Avengers: Doomsday.

Looking Ahead

Marvel Studios typically reveals major casting at events like San Diego Comic-Con (July), D23 (August), or via controlled press drops. The next likely window for Avengers: Doomsday announcements is summer 2025, roughly a year before release.

Until then, the Latverian Witch theory remains exactly that—a theory. The Loki star’s comment is intriguing but not definitive. Wanda Maximoff’s return is possible, even narratively satisfying, but not confirmed by any official source.

We will continue to monitor credible industry reporting and official channels for updates. For now, the multiverse remains full of possibilities—and very old magic, whatever form it takes.
