First Official Avengers: Doomsday Image Has Fans Making Wild Guesses

The first official trailer for Avengers: Doomsday is dropping on Thursday this week, but the men at the helm are already teasing fans with their own sneak peek. However, this “first look” does not boast very much to look at.

Joe and Anthony Russo shared an Instagram post with the hashtag #AvengersDoomsday on Dec. 15, 2025. It is a very tight, blurry close-up of an identifiable image, appearing as a Y-shaped white object in front of a dark background.
