Robert Downey Jr. appears as Doctor Doom in the first full trailer for Avengers: Doomsday, and Marvel Studios gives him a green cloak and metal mask instead of the armor audiences associate with Tony Stark. The clip lands with a 503 million-view opening in its first 24 hours, a scale that puts the trailer at the second-largest movie launch of all time.
Doctor Doom in full
The first full look matters because it is the first time Downey is shown in the role without the rollout language around teasers. He is presented as Victor von Doom, the despotic leader of Latveria, which makes the casting shift the point rather than a side note. For readers tracking Marvel’s next phase, that is the real pivot: Downey is back in the MCU, but as a villain.
Thor tells the team to “put aside your petty squabbles” and adds, “We’re going to need a miracle.” Those lines give the trailer a blunt mission statement, and they also set up a crossover built around damage control rather than celebration. The footage is not selling mystery for its own sake; it is selling a collision of franchises.
Steve Rogers returns
Chris Evans returns as Steve Rogers for the first time since 2019’s Avengers: Endgame, and the trailer shows him summoning Mjolnir again. That image does more than reward continuity hunters. It signals that Marvel Studios is leaning hard on legacy characters while trying to frame Avengers: Doomsday as a new confrontation instead of a greatest-hits reel.

Scott Lang shares a quiet moment with Cassie, Bucky Barnes is among the heroes assembling, and Shang-Chi appears after his MCU debut in Shang-Chi and the Legend of the Ten Rings. The trailer also shows The Thing shaking hands with M'Baku, bringing the Fantastic Four and Wakandans into the same frame. That mix tells viewers where the studio wants the next crossover to land: across multiple franchises, not within one corner of the MCU.

December 18 is the date that gives all of this its commercial edge, because that is when Avengers: Doomsday opens in theaters. The footage leaves one practical question hanging over the whole rollout: how Victor von Doom fits into the plot. Marvel Studios has shown the mask, the cloak, the team-up crowding, and the return of Downey; the movie now has to cash that in on screen.
