Avengers: Doomsday To Include Doom, Fantastic Four

A recent TikTok from the Russo Brothers' AGBO showed costumes for Sue Storm, Doctor Doom and Franklin Richards but appears to be recycling previously seen looks rather than revealing plot spoilers. Avengers: Doomsday is scheduled for release on December 18, 2026, and will fold the Fantastic Four into the mainline MCU while bringing back high-profile characters, including Namor, Shang‑Chi, several former Fox X‑Men actors, and Robert Downey Jr. as Victor von Doom under the Russos. Chris Hemsworth’s Thor is billed as a major presence in the film, with reports suggesting the production could again use large-scale tonal stakes, including the possibility of the character being killed or sacrificed. Fans and outlets have proposed that Doctor Strange and multiversal mechanics could provide an in-world explanation for any connection between Iron Man and Doom and justify RDJ’s villain casting. In Marvel Comics, Doom’s long reign concludes with One World Under Doom #9 on November 19, 2025, followed by the Dungeons of Doom miniseries in January 2026, indicating coordinated high-profile Doom storytelling across media.
