Marvel Fans Anticipate Early Trailer Release for Avengers: Doomsday

Excitement is building among Marvel fans as hints emerge that the first trailer for Avengers: Doomsday may be released sooner than expected. Recent posts on Disney’s Latin America Instagram account have sparked speculation about an imminent teaser, fueling anticipation for the upcoming film set to be a part of Marvel’s Phase 6.

On November 26, 2025, Disney+ Latin America shared a story featuring an image from The Fantastic Four: First Steps, accompanied by the caption, “the world is getting ready for a new event.” This post quickly caught the attention of fans, who captured screenshots before they disappeared after 24 hours. The image depicted a pivotal moment involving Robert Downey Jr.’s character, Doctor Doom, meeting Franklin Richards, the son of Reed Richards and Sue Storm from The Fantastic Four.

The very next day, the Brazilian social media accounts for Marvel and Disney+ posted another clue, this time a screenshot from the post-credits scene of Thunderbolts. This image, which featured a close-up of The Fantastic Four’s spaceship, was shared with the message: “They’ve already started preparing for the meeting… and you, what’s your theory?” These posts, while not explicitly announcing the trailer’s release, have led fans to believe that significant news is on the horizon.

Countdown to Brazil Comic-Con 2025

The timing of these posts is notable as they coincide with Brazil Comic-Con (CCXP), scheduled for December 4 to 7, 2025. CCXP is renowned for its major announcements and exclusive previews, making it a prime stage for Marvel to unveil new content. While it’s uncommon for Marvel to reveal major teasers at CCXP—often opting for the more prominent San Diego Comic-Con (SDCC)—the buzz surrounding these social media hints suggests that fans should remain alert.

Previous rumors indicated that a teaser for Avengers: Doomsday could debut ahead of public screenings for Avatar: Fire and Ash, Disney’s final major release of the year. Speculation intensified when industry insiders suggested that some audiences might get an exclusive preview at a specific event in December.

Social media user Cryptic4Qual, known for sharing film industry insights, mentioned the potential for an earlier viewing of the teaser, although they did not expect an official premiere at CCXP. This has only heightened fan enthusiasm, particularly within online communities dedicated to Marvel discussions.

What’s Next for Marvel Fans?

As anticipation grows, many fans are curious about when the trailer might officially drop. If Marvel chooses to capitalize on the December release of Avatar 3, it could strategically unveil the Avengers: Doomsday trailer shortly after CCXP, potentially around December 19, 2025. This approach would not only generate excitement for the new movie but also attract MCU fans to Disney’s flagship film.

While the possibility of the teaser leaking early exists—especially if it makes an appearance at CCXP—Marvel and Disney are likely to keep a tight hold on the release strategy to maximize audience engagement. Fans are eagerly awaiting confirmation and are prepared for any updates regarding the highly anticipated trailer.

As the Marvel universe continues to expand, the excitement surrounding Avengers: Doomsday reflects the enduring appeal of its characters and stories. With each new hint and teaser, the connection between Marvel and its global audience grows stronger, keeping fans on the edge of their seats.
