Every week since the release of Avatar: Fire & Ash (released on December 10, 2025) the Marvel Cinematic Universe (MCU) has released a new Avengers: Doomsday trailer strictly premiering before every Avatar viewing. Avengers: Doomsday, directed by Joe and Anthony Russo, is the most anticipated MCU film since Avengers: Endgame released in 2019.
With the trailers exclusively being released in theaters, the Marvel fanbase has been overloaded with excitement throughout social media. Each trailer was designed to focus solely on a different beloved Marvel character or group.
The first trailer released in theaters on December 18, then on Tuesday, December 23 on YouTube. The first installment focused on Steve Rogers, aka Captain America – who traveled back in time and eventually stayed in the past to be with his love, Peggy Carter. In the trailer, he appears to be holding a baby that is assumed to be his own, which could be a cause of multiversal disruption, as it may not have been supposed to happen. “My least favorite trailer was the Captain America one,” junior Griffin Lorenz states. “It just felt like nostalgia bait and I don’t feel like there’s a need for him to come back.” True, Steve Rodgers’ Captain America was supposed to be retired, but if this is what the Russo brothers think is best for the future of the MCU, it might be best to believe in their decision. Junior Salvatore Gigante thinks alike, “I like Captain America, I am happy he is back,” the first trailer was his favorite.
The second trailer, released in theaters on December 25 and on YouTube on Tuesday, December 30, was based on the God of Thunder, Thor, who was praying to his father Odin for strength. After the events of Thor: Love and Thunder, Thor adopted the orphan, Love, to be his daughter. He is praying for strength in order to see his daughter after one last battle, who fans assume is Doctor Doom. Senior, Jayden Fermin shares, “I didn’t like how they brought back his old hair style because I liked the long hair. It’s a downgrade. But I do find it interesting that Thor is praying to Odin because he is dead. If you didn’t watch Thor: Love and Thunder, you’re out of luck: spoilers.”
The third trailer, released in theaters on January 1 and on Youtube on Tuesday, January 6, was a minimal teaser with the most famous Marvel Comics team, the X-Men, making their first official MCU appearance. Professor Xavier and Magneto are having a conversation while the scene shows Xaiver’s School for Gifted Youngsters, generally the hideout for the X-Men, appearing destroyed. At the end of the trailer, the leader of the X-Men, Cyclops, appears to be pained and heartbroken, taking off his visors and releasing his red eyes’ full potential while wearing his comic-accurate suit. Senior Sean Delaney believes, “It was great to see Cyclops in his comic accurate suit. I would have to guess his scene had to do with the sentinels–which are mutant killing robots–as he is surrounded by rubble. It gives the feeling of him giving a last effort to save his family, a theme that reins throughout the X-Men’s history.”
Moreover, Lorenz says, “My favorite trailer was the X-Men one because I love those characters and I’m glad they’re coming back. It was also the only trailer that actually showed anyone really using their powers.”
The fourth and final trailer, released in theaters on January 8 and on YouTube on Tuesday, January 13 is based around Shuri and the Wakandans, and Namor and the Talokani, who both seem to also be experiencing loss. The end focuses on the Fantastic Four leaving their universe, as seen in the post-credit scene in the Thunderbolts, with the reasoning behind the departure speculating around the Fantastic Four: First Steps’ post-credit scene. The Fantastic Four’s arrival is greeted by the Wakandians, with King M’Baku and The Thing shaking hands with a few words exchanged to clear the air. Junior Colin Mitchell comments, “I’m intrigued by what’s to come and how The Thing (and the Fantastic Four) develops in the plot of the movie.”
Marvel’s decision to release these trailers in theaters has strengthened the novelty of physically going to see a film–a clever move to boost the ticket sales for Avatar: Fire & Ash, while creating deep excitement for Doomsday. The Avengers, X-Men, and Fantastic Four coming together points to an impending unifying threat that will take everything the heroes have. Although Doctor Doom’s appearance has not yet been confirmed, he is referred to indirectly throughout the teasers and is widely believed to be the antagonist in the film, hence the name Avengers: Doomsday.
Centered around loss and responsibility, these trailers explore how the heroes handle the aftermath of Avengers: Endgame. Although these clips have been described as trailers or teasers, director Joe Russo claims, “…they are not teasers. Or trailers. They are stories…Pay attention.” Each “trailer/teaser,” as we call it, shows how a different character or group responds to what was lost, creating additional emotional stakes that could foster both alliances and conflicts. The actual Avengers: Doomsday trailer is expected to release during one of the Superbowl LIX commercial breaks on February 8. This aligns with Marvel’s history of major Super Bowl drops, also ensuring the teaser is witnessed by the largest possible audience.
