MCU fans lucky enough to attend Disney’s CinemaCon 2026 presentation were rewarded, as Kevin Feige and friends debuted a brand new trailer for Avengers: Doomsday. Most notably, this trailer is the first to feature Robert Downey, Jr.’s Doctor Doom, along with a host of X-Men, Avengers, and Fantastic Four characters.
Marvel likely isn’t releasing the trailer online just yet, but IGN was in the room and we can break down the footage.
The trailer opens with a shot of the Xavier Institute sign. The narration (presumably Downey as Doom) says, “Something is coming, something we might not be able to deter. Before this day is done, we shall divest with an unthinkable decision.” Patrick Stewart’s Xavier sees a bright light in the sky. We see Doom in profile.
