Thunderbolts* | New "Sentry" Trailer

The second Thunderbolts* trailer offers dire prospects for one member of the titular MCU team. Marvel unveiled various trailers for the MCU's upcoming releases at D23 Brazil 2024, including Captain America: Brave New World and Thunderbolts* — two of Marvel Studios' biggest 2025 projects alongside The Fantastic Four: First Steps and Disney+ shows like What If...? season 3. Ahead of Thunderbolts*' May 2025 release date, the film's premise is clear: Valentina Allegra de Fontaine assembles a group of assassins against their will in order to complete a deadly mission.

The MCU's Thunderbolts are quite different from the original Marvel Comics team. Instead of a supervillain team posing as the Avengers' replacement, Valentina Allegra de Fontaine's Thunderbolts are a ragtag group of former criminals who are pressured into working for her. This change makes the team more similar to later iterations like Norman Osborn's secret ops team, which quickly transforms into the Dark Avengers. Such a transformation could be an explanation for the asterisk in the Thunderbolts* title, revealed at the end of the movie.
