Marvel Studios has released the first full trailer for Avengers: Doomsday, giving fans their clearest look yet at Robert Downey Jr. as Doctor Doom and teasing the long-awaited return of Chris Evans. The action-packed preview sets the stage for one of the Marvel Cinematic Universe’s biggest battles, bringing together heroes from across multiple franchises ahead of the film’s theatrical release on December 18, 2026.

Robert Downey Jr. Returns to the MCU as Doctor Doom

After defining the MCU as Tony Stark/Iron Man for more than a decade, Robert Downey Jr. returns in a dramatically different role. The trailer offers the first extended look at him wearing Doctor Doom’s iconic armor and mask, positioning the legendary Marvel villain as the central threat in the upcoming film.

The footage suggests that Doom will play a pivotal role in a multiverse-spanning conflict, marking a major shift from Downey’s previous heroic legacy within the franchise.

Chris Evans’ Return Steals the Spotlight

One of the trailer’s biggest surprises is the return of Chris Evans.

In a standout moment, Thor reacts with disbelief after seeing Evans’ character, declaring that it should not be possible. The trailer then briefly shows Evans wielding Mjolnir, a callback that has already generated widespread discussion among Marvel fans.

Marvel has not revealed the full context of his return, leaving audiences to speculate about his role in the multiverse storyline.

Familiar Heroes Assemble Once Again

The trailer reunites several fan-favourite characters from across the Marvel universe.

Among those featured are:

• Chris Hemsworth as Thor
• Letitia Wright as Black Panther
• James Marsden as Cyclops
• Members of the Fantastic Four
• Heroes from the X-Men universe
• Additional Avengers and allies from across the MCU multiverse

Thor is shown rallying the team with an emotional appeal as Earth’s Mightiest Heroes prepare to face Doctor Doom and the growing multiversal threat.

Russo Brothers Return to Direct

Avengers: Doomsday marks the return of Joe and Anthony Russo, who direct an MCU film for the first time since Avengers: Endgame (2019). The screenplay is written by Stephen McFeely, with the film continuing Marvel’s Multiverse Saga.

Their return has raised expectations among fans, given the critical and commercial success of their previous Marvel projects.
