Sentry’sMCUactor may have been confirmed at theThunderboltsSan Diego Comic Con2024 panel.Screen Rantattended San Diego Comic Con 2024, where a few updates onPhase 5’s upcomingThunderbolts. The main members ofthe star-studdedThunderboltscast, including Sebastian Stan, Florence Pugh, and David Harbour, discussed their characters. ExclusiveThunderbolts*footage also showed most members of the team crossing paths for the first time.

During theThunderbolts*presentation at San Diego Comic Con actor Lewis Pullman revealed that he’s playing a character named Bob, but didn’t disclose any further details. However, the only Marvel Comics character named Bob who’s connected to the Thunderbolts is Robert Reynolds, Sentry’s civilian identity. In the comics, Robert Reynolds becomes Sentry when he consumes an upgraded version of the Super Soldier serum.

Why Thunderbolts* Would Be Right To Keep Sentry A Movie Secret

Marvel Would Be Right To Wait A Little Longer To Reveal Sentry As Thunderbolts*' Main Villain

San Diego Comic Con 2024 seemed like an ideal opportunity to raise anticipation forThunderbolts*, as Sentry is one of the most powerful characters in Marvel Comics lore. However,Sentry’s full reveal can have a bigger impact closer toThunderbolts*' April 2025 release date.Thunderbolts*can still heighten expectations with costume reveals, a clearer explanation of Val’s villainous plans, and the confirmation of the Thunderbolts' mission — not to mention a first trailer that could include part oftheThunderbolts*footage seen at San Diego Comic Con, which featured the team meeting each other.

Kevin Feige Still Hasn’t Explained The Asterisk In The Thunderbolts* Title

In 2024, Marvel Studios’ Thunderbolts was retitled as Thunderbolts*, yet Kevin Feige still did not explain the mysterious asterisk at SDCC 2024.

Sentry’s immense power presents a nearly impossible challenge for Val’s Thunderbolts, meaning that most ofThunderbolts*' runtime might focus on the team and their attempt to get along with each other, similar to the Avengers when they first assemble to fight Loki in 2012’sThe Avengers. It would then make sense for Robert Reynolds' Sentry transformation to be saved forThunderbolts*' third act, leading to an intense final battle between Sentry and the Thunderbolts. In that case, it would only be appropriate for theThunderbolts*' marketing plan to avoid showing Sentry altogether.

Steven Yeun was set to play Sentry inThunderbolts*', but he had to drop out due to scheduling conflicts.

Lewis Pullman stood alongside the rest of theThunderboltscast at San Diego Comic Con panel. With the exception of Taskmaster actor Olga Kurylenko, Valentina Allegra de Fontaine’s whole team was present at San Diego Comic Con. Therefore, Lewis Pullman’s “Bob” character is unlikely to be a simple human character, at least not one who doesn’t eventually gains the power of a million suns during the MCU’sThunderbolts.
