Marvel Fans Anticipate Early Trailer Release for Avengers: Doomsday

Fans of the Marvel Cinematic Universe are buzzing with excitement as speculation mounts around an early release of the trailer for Avengers: Doomsday. Recent social media posts from Disney’s Latin America accounts have fueled this anticipation, suggesting that the first teaser might drop sooner than expected.

On November 26, 2025, a story post on Disney’s Latin America Instagram account featured a caption stating, “the world is getting ready for a new event.” The accompanying image showcased a scene from the mid-credits of The Fantastic Four: First Steps, highlighting a meeting between Robert Downey Jr.’s Doctor Doom and Franklin Richards, the son of Reed Richards and Sue Storm. This post, although fleeting, was captured by fans and has since sparked discussions about the upcoming movie.

The following day, the Brazilian Marvel and Disney+ accounts shared another intriguing post. This time, it included a screenshot from the post-credits scene of Thunderbolts, featuring a close-up of The Fantastic Four’s spaceship along with the caption: “They’ve already started preparing for the meeting… and you, what’s your theory?” This sequential teasing has led fans to believe that something significant is on the horizon for Avengers: Doomsday.

Potential Trailer Release Timing

Although neither post confirms an imminent trailer release, the timing closely aligns with the upcoming Brazil Comic-Con (CCXP), scheduled for December 4-7, 2025. This event, regarded as one of the largest for comic book announcements and reveals, often serves as a platform for major industry players like Marvel and DC. While CCXP usually does not reach the same level of hype as San Diego Comic-Con, many fans speculate that Marvel could choose this venue to unveil the teaser for one of 2026’s most anticipated films.

Additionally, rumors have circulated that a teaser for Avengers: Doomsday might premiere before public screenings of Avatar: Fire and Ash, Disney’s last major release of the year. Industry reports have indicated that the trailer could debut before the end of 2025, heightening the anticipation among fans.

Adding to the excitement, an insider on social media suggested that some audiences could receive an early glimpse of the trailer during a specific Sunday event in December. This has led to speculation that the teaser might aim to drive interest for Avatar 3, which releases on December 19, 2025. By linking the marketing of Avengers: Doomsday with a major release like Avatar 3, Marvel could effectively attract MCU fans to the theaters.

What to Expect Next

As fans eagerly await further announcements, the possibility of a trailer debuting at CCXP remains a topic of heated discussion. If Marvel decides to showcase the teaser at the event, it may not be publicly available for some time afterward, as Disney will likely prioritize maximizing attendance for Avatar 3. Should the trailer leak online post-CCXP, Marvel could opt for an earlier public release.

In the meantime, the build-up continues as Marvel devotees keep a close eye on social media channels for any additional clues regarding Avengers: Doomsday. With a rich history of interconnected storylines and beloved characters, anticipation is palpable in the lead-up to what could be a groundbreaking addition to the Marvel franchise.

As the situation develops, fans are encouraged to stay tuned for updates on the first teaser and other related announcements from Marvel.
