A new trailer for season 3 of X-Men '97 was shown at the New York Comic Con 2026, surprising fans with appearances by Deadpool and She-Hulk. The preview features the characters at the wedding of Malicia and Gambit, but their specific roles in the story remain unclear. They might only appear briefly at the event. Deadpool has previously crossed over with the X-Men in other media, hinting at a more substantial role this time. The trailer also highlights the Brotherhood of Mutants, a group of anti-heroic mutants, including Pyro, Avalanche, Toad, and Colossus. In the footage, they write "freedom for mutants" on a building's wall before being attacked by a sentinel— a robotic enforcer—painted in red, white, and blue. The trailer suggests that Mystique is now leading the Brotherhood following the death of Magneto, who was killed by Apocalypse in season 2. During a panel at San Diego Comic-Con, executive producer Brad Winderbaum noted that the studio was working on finalizing the animation for season 3 while wrapping up season 2. The release of the trailer implies that season 3 might come out sometime next year, though Marvel has not yet provided more details about its release date or plot. The new footage has generated excitement among fans, who are eager to see how the X-Men universe will evolve with the inclusion of new characters and the continuation of ongoing storylines. The trailer offers a glimpse into what could be a pivotal season for the series, building on the events of the previous two seasons.
