Avengers Doomsday Teaser: Doctor Doom Joins the MLB World Series Crossover, but Fans Want More
Marvel Studios has unveiled a special promotional preview of Avengers Doomsday during Game 1 of the 2026 Major League Baseball World Series. The release brings together the Marvel Cinematic Universe and professional baseball in a crossover designed to build anticipation for one of the studio’s biggest upcoming superhero films.
The preview aired during the World Series game between the Milwaukee Brewers and the Tampa Bay Rays on October 23, 2026. It features well-known baseball players alongside Marvel characters, combining the atmosphere of a major sporting event with footage from the upcoming film. While the crossover attracted attention, some fans were disappointed by the limited amount of new footage shown in the teaser.
Doctor Doom Makes an Appearance in the New Preview
One of the key attractions of the promotional video is the appearance of Robert Downey Jr as Doctor Doom. The actor, widely known for playing Tony Stark and Iron Man in earlier Marvel films, is taking on a different role in Avengers Doomsday.
The teaser includes a baseball sequence featuring Pedro Pascal as Reed Richards, also known as Mister Fantastic, and Joseph Quinn as Johnny Storm, or the Human Torch. The scene places the superhero characters in a baseball setting, with Mister Fantastic using his extraordinary abilities during a ceremonial first pitch.
Several Major League Baseball players also feature in the promotional material. These include Bryce Harper, Freddie Freeman, Jacob Misiorowski, Junior Caminero and Randy Arozarena. The video then moves towards the arrival of Doctor Doom, suggesting the scale of the threat facing the heroes.
According to MLB’s official report, the crossover was created specifically for the World Series broadcast. It connects the sporting event with the film’s wider story, which brings together heroes from different fictional realities to confront a major threat.
Familiar Marvel Heroes Return
Alongside Doctor Doom, the preview features glimpses of several familiar Marvel characters. Chris Evans appears as Steve Rogers, while Chris Hemsworth returns as Thor. The clip also includes Letitia Wright as Black Panther, Paul Rudd as Ant-Man and Anthony Mackie as Captain America.
The appearance of Steve Rogers is particularly notable because Anthony Mackie’s Sam Wilson currently holds the Captain America mantle in the Marvel Cinematic Universe. The promotional clip plays on that situation, creating a moment of confusion for Ant-Man about which Captain America to contact.
The film is expected to bring together characters from several parts of the Marvel universe, including the Avengers, the Fantastic Four and other returning superhero teams. The ensemble cast also includes actors associated with earlier Marvel franchises, expanding the scale of the crossover.
However, the World Series preview is a promotional clip rather than a full-length trailer. It offers a short look at selected characters and scenes without revealing the complete plot.
Why Some Fans Were Disappointed
Despite the high-profile sporting partnership, the teaser received mixed reactions online. Some viewers were excited to see Marvel characters incorporated into the World Series broadcast, while others felt that the new material did not meet their expectations.
According to TheWrap’s report on the response, some fans criticised the preview because it contained only a small amount of fresh footage. Their disappointment was linked to the anticipation created by the announcement of an exclusive preview during the baseball game. Some viewers expected a more substantial reveal or a longer look at Doctor Doom and the returning heroes.
The criticism does not mean that all fans reacted negatively. Other viewers supported Marvel’s decision to keep the preview brief, arguing that showing too much before the film’s release could reveal important story details. This difference in opinion reflects the challenge studios face when promoting highly anticipated films: audiences want new information, but they may also prefer that major plot points remain secret.
The teaser’s reception therefore appears mixed rather than universally negative. The online responses reported by entertainment outlets highlight the expectations surrounding the film and the debate over how much footage a promotional campaign should reveal.
Release Date and Creative Team
Avengers Doomsday is scheduled to release in theatres on December 18, 2026. Joe and Anthony Russo, known for directing Avengers Infinity War and Avengers Endgame, are returning to direct the film. The screenplay is credited to Michael Waldron and Stephen McFeely, with Marvel Studios president Kevin Feige among the producers.
The film is positioned as a major crossover event, bringing together characters from different corners of the Marvel Cinematic Universe and related Marvel film franchises. Robert Downey Jr’s casting as Doctor Doom has been one of the most closely watched developments in the project’s promotion.
The story is expected to revolve around a serious threat to multiple realities. Although promotional material has provided glimpses of the returning heroes, the full details of the conflict remain under wraps.
Avengers Doomsday is also expected to lead into Avengers Secret Wars, which is scheduled for release in December 2027. The two films are part of Marvel’s broader plans for its ongoing multiverse storyline.

What the MLB Crossover Means for the Film’s Promotion
The World Series partnership gives Marvel an opportunity to reach audiences beyond its usual superhero fan base. The championship series attracts substantial attention from baseball viewers, making it a prominent platform for a major entertainment promotion.
By featuring professional baseball players alongside Marvel characters, the campaign connects two different entertainment audiences. The promotional sequence also uses the baseball setting as part of its storytelling, rather than relying entirely on conventional film footage.
Whether this approach translates into greater excitement for the movie remains to be seen. A short promotional video can generate discussion, but audience interest in the finished film will also depend on its story, performances, reviews and wider marketing campaign.
For now, the new preview has achieved visibility while also prompting debate about how much fresh material Marvel should reveal ahead of the release.
What Happens Next
Marvel Studios is expected to continue promoting Avengers Doomsday as the December 18 release date approaches. Future trailers and official announcements may provide more details about Doctor Doom, the returning characters and the central conflict.
For viewers hoping for an extended look at the film, the World Series teaser may not have answered many questions. However, it has offered another glimpse of the crossover and confirmed the involvement of several familiar characters in the promotional campaign.
The clearest takeaway is that the new teaser has generated mixed reactions. Some viewers welcomed the unusual Marvel and MLB collaboration, while others wanted more new footage. The full response to Avengers Doomsday will become clearer as the release approaches and more official material becomes available.
