Marvel Studios releases first glimpse of Avengers: Doomsday

Directors Joe and Anthony Russo posted a solid green square on social media that is the heraldic emblem of Doctor Doom, confirming the visual identity for the upcoming Marvel film Avengers: Doomsday. The image sparked fan analysis of the hexadecimal shade (#71826a) and speculation that a trailer could drop within days. Industry observers note that the studio is likely to use the teaser ahead of its planned December 2026 release and to build momentum toward the San Diego Comic‑Con 2026 marketing push.

The tease follows the Russo brothers' recent panel appearance in London and suggests that the film will serve as a prelude to the larger Avengers: Secret Wars storyline slated for the following year.
