Marvel Studios has revealed a new look for Doctor Doom, played by Robert Downey Jr., at the Walt Disney Studios Marketing Expo in Shanghai, signaling his appearance in the upcoming film Avengers: Doomsday, scheduled for release on December 18, 2026.

The film is expected to be Marvel's biggest yet, featuring a star-studded cast including the return of X-Men characters, the Fantastic Four, and the New Avengers, with production nearing completion.

Fans are speculating about character appearances and plot details, with teasers and social media activity fueling rumors of Deadpool's involvement, possibly connecting the X-Men universe to the MCU.

The film will include major characters like Professor Charles Xavier, played by Sir Patrick Stewart, and the debut of the Fantastic Four, with actors such as Pedro Pascal confirmed for Reed Richards.

Additional cast members include Florence Pugh as Yelena, Chris Evans potentially returning as Captain America, and Chris Hemsworth reprising Thor, with some actors filming scenes in isolation amid ongoing script rewrites.

The storyline may involve a multiverse chase, with Doctor Doom wielding Thor's Mjolnir and sitting on a throne, hinting at power struggles across different realms and possible conflicts with Loki and Thor.

Filming leaks, set photos, and actor comments suggest a major fight involving Gambit and Doctor Doom, with some speculation about the role of the TVA and other cosmic elements.

Reynolds has played a playful game on social media, posting Easter eggs and teasing his possible return as Deadpool, though his involvement remains unconfirmed and is a source of fan excitement.

The film is part of the MCU's Multiverse Saga and is positioned as a key installment leading up to Avengers: Secret Wars, with many characters and storylines converging in a massive, interconnected event.

While details about the plot are still sparse, the film's scale and scope are described as unprecedented, with actors and creators emphasizing its epic nature and the significant role of characters like Doctor Strange, who may or may not appear.

The movie's visual design features detailed armor, chain mail, and symbolic elements like Mjolnir, hinting at a visually striking interpretation of Doctor Doom and the multiverse chaos to come.

With the passing of Julian McMahon, the original Victor Von Doom actor, Marvel is likely introducing a new portrayal, and the storyline may involve a major confrontation with the Fantastic Four and other heroes.
