It’s not yet known when Marvel will release Avengers: Doomsday‘s first trailer, but rumors indicate that it could premiere in theaters ahead of Avatar: Fire and Ash on December 19th (per Collider), or debut online even sooner. For Doomsday to generate the electrifying buzz it needs, the following five elements should be present in its first trailer.
5) Sam Wilson’s Avengers and the New Avengers Together

As of now, the Avengers roster in Doomsday consists of Captain America, Thor (Chris Hemsworth), Scott Lang/Ant-Man (Paul Rudd), Shang-Chi (Simu Liu), Shuri/Black Panther (Letitia Wright), and Joaquín Torres/Falcon (Danny Ramirez). The team will likely find itself in a conflict with the Thunderbolts, who, since being officially branded the New Avengers at the end of the titular film, serve as the world’s protectors. The group of anti-heroes, comprised of Yelena Belova (Florence Pugh), Bucky Barnes (Sebastian Stan), Ava Starr/Ghost (Hannah John-Kamen), Alexei Shostakov/Red Guardian (David Harbour), John Walker/U.S. Agent (Wyatt Russell), and Bob Reynolds/Sentry (Lewis Pullman), should see its status challenged.
Even so, it’s probable that Sam’s Avengers and the New Avengers will team up to fight Doctor Doom at some point. There might exist some initial tension between the two camps as they sort out who the actual Avengers are, but the presence of a multiversal threat should bring them together. Whether clashing or supporting each other, the Avengers and New Avengers need to appear simultaneously in Doomsday‘s first trailer. The first look could hint at their dispute or depict them in battle alongside one another. Either way, any interaction between members of the Avengers and the New Avengers would excellently set up the story to come in Doomsday.
4) Reed Richards Meeting Doctor Doom

Reed Richard/Mr. Fantastic (Pedro Pascal) and Doctor Doom’s meeting in Avengers: Doomsday is highly anticipated due to the pair’s legendary rivalry in Marvel Comics. A complex relationship defined by their shared intelligence and competitive nature, Reed and Doom have so much history that the MCU could incorporate into Doomsday. The Fantastic Four: First Steps (2025) confirms that the MCU’s version of Doom originates from Earth-828; however, the iconic villain doesn’t appear in the movie until its mid-credits scene. Thus, a moment or two of Mr. Fantastic and Doom facing each other, or even fighting, should be enough to get fans really hyped for the film.
