Disney screened a second official trailer for Avengers: Doomsday at the D23 fan convention, revealing Robert Downey Jr as Doctor Doom alongside the X-Men.
The new footage from the upcoming 39th film in the Marvel Cinematic Universe showcases the Latverian villain Victor von Doom wielding multiversal power and controlling giant Sentinels as he clashes with Earth's heroes.
Running for more than two minutes, the trailer presented during Disney's ultimate fan event deepens the multiversal collision caused by Doctor Doom. In one central sequence, Sue Storm, also known as the Invisible Woman and played by Vanessa Kirby, warns a gathering of Earth's mightiest heroes about the threat. She explains that she knew he was lost, but did not realize he was broken, setting up the character's tragic history and underlying motivations.
The preview also features Reed Richards, played by Pedro Pascal, confronting Victor von Doom. The interaction highlights a deep emotional bond and prior history between the villain and the Fantastic Four, Marvel's foundational superhero team.
Doctor Doom Battles Thor
Doctor Doom's formidable strength takes center stage as he sits upon a throne, manipulating cosmic events to gather sufficient multiversal power to rewrite reality. When Thor, portrayed by Chris Hemsworth, attempts to intervene, the sovereign of Latveria stops a strike from Thor's battleaxe, Stormbreaker, dead in its tracks. The confrontation underscores that the Asgardian avenger cannot defeat Doom alone.
Thor has long served as one of the core Avengers within the Marvel Cinematic Universe, wielding the enchanted weapon Stormbreaker in battle across alternate realities and cosmic realms.
Multiversal Hero Alliances
Building on themes established in earlier previews, the clip highlights several cross-universe team-ups. Gambit, played by Channing Tatum, is seen channeling kinetic energy, while Mystique, played by Rebecca Romijn, shape-shifts before Yelena Belova, played by Florence Pugh.
The trailer further includes emotional interactions between Professor X, played by Patrick Stewart, and Magneto, played by Ian McKellen. Other family dynamics featured include Scott Lang, the hero Ant-Man played by Paul Rudd, alongside his daughter Cassie, played by Kathryn Newton, as well as Thor with Love.
The inclusion of Mystique, Magneto, and Professor X brings key figures from the X-Men universe into direct contact with members of the Thunderbolts and the New Avengers, marking an unprecedented expansion of shared Marvel character lineages.
Doctor Doom and the Sentinels
Among the most discussed moments in the new trailer is a sequence depicting Victor von Doom commanding colossal Sentinels, the robotic enforcers historically associated with hunting mutants. In addition to the narrative implications, Doom assumes a posture that mirrors Tony Stark's iconic pose when introducing the Jericho missile in the original 2008 Iron Man film.
Robert Downey Jr previously anchored the Marvel Cinematic Universe for over a decade as Tony Stark and Iron Man. His return to the franchise as Doctor Doom represents a major narrative pivot for the overarching cinematic story.
First Trailer and Production Details
The initial trailer for the film was released in July 2026, confirming the return of Chris Evans as Steve Rogers, also known as Captain America. That first teaser depicted Thor gathering allies to prepare for a decisive conflict across multiple timelines and alternate realities in the Marvel Cinematic Universe.
Avengers: Doomsday is directed by Anthony Russo and Joe Russo, from a screenplay written by Michael Waldron and Stephen McFeely. The feature is produced by Kevin Feige alongside Anthony and Joe Russo, and is scheduled to open in cinemas on December 18, 2026.
