The tentative translation of the synopsis from the Disney 2026 Merchandise Expo in China states, “Doctor Doom has officially arrived in the MCU. This villain, a master of cutting-edge science and powerful magic, will unleash a cascading crisis across the entire Multiverse” (via MovieWeb). Robert Downey Jr. will portray Victor von Doom, assembling against the Avengers, Fantastic Four, X-Men, and other teams across realities.

Additional promotional material from the expo highlighted Doom’s armor and hinted at a potential confrontation with Thanos. High-definition artwork revealed intricate details of his comic-accurate costume, including runes that emphasize his mastery of sorcery. Fans also noted what appeared to be Shang-Chi’s Ten Rings on his arm. These seemed to tie into Kamala Khan’s bangles and other Multiversal artifacts once connected to Kang the Conqueror.

Downey is approaching the role with significant preparation. Filmmaker Anthony Russo explained in an interview with Entertainment Tonight, “He’s writing backstory, costume ideas… he just really loves rich three-dimensional characters, and I think he sees a real opportunity here.”

At SXSW earlier in the year, Downey also reflected on his years as Tony Stark, stating, “17 years I’ve been associated with an iconic superhero, but you know, it’s the message he represents that I’m grateful for” (via Screen Rant).

In the comics, Doom’s blend of science and magic has allowed him to rise to immense power, including becoming God Emperor Doom during 2015’s Secret Wars. The synopsis positions him in a similar light, indicating that his schemes will affect the entire Multiverse.

Directed by the Russo Brothers from a screenplay by Stephen McFeely and Michael Waldron, Avengers: Doomsday features a massive ensemble cast, including Chris Hemsworth, Anthony Mackie, Florence Pugh, Simu Liu, Pedro Pascal, Vanessa Kirby, and returning X-Men stars.
