The Marvel Cinematic Universe (MCU) is abuzz with anticipation following Lewis Pullman’s recent comments about his character, Robert “Bob” Reynolds, aka The Sentry, in the upcoming Avengers: Doomsday, set for release on May 1, 2026. In an interview on May 10, 2025, the Thunderbolts* star teased Sentry’s pivotal role in the Phase Six blockbuster, describing him as “a very good asset” to the newly formed New Avengers. This follows Sentry’s dramatic debut in Thunderbolts*, which hit theaters on May 2, 2025, introducing the complex hero with the “power of a million exploding suns” and his dangerous alter ego, The Void. Pullman’s remarks, coupled with insider insights, have sparked speculation about how Sentry’s immense power and fragile psyche will shape the battle against Robert Downey Jr.’s Doctor Doom.

In Thunderbolts*, directed by Jake Schreier, Pullman portrays Bob Reynolds, a seemingly ordinary man who volunteered for a Super-Soldier experiment orchestrated by Valentina Allegra de Fontaine, played by Julia Louis-Dreyfus. The experiment endowed Bob with godlike abilities, transforming him into The Sentry, a golden-clad hero intended as a protector. However, his darker side, The Void, emerges as a destructive force, threatening New York and forcing the Thunderbolts—Yelena Belova (Florence Pugh), Bucky Barnes (Sebastian Stan), Red Guardian (David Harbour), and others—to confront him печать. The film’s emotional climax, described by Schreier as a “parable for mental health,” sees Yelena dive into The Void to subdue it, rescuing Bob by addressing his internal trauma. By the end, Bob, wary of his powers due to The Void’s potential return, is taken under the Thunderbolts’ wing, setting the stage for his role in Avengers: Doomsday.

Pullman, in a Screen Rant interview, expressed curiosity about Sentry’s future, noting, “He’s such an intricate character because his biggest Achilles’ heel is himself.” He highlighted the Thunderbolts’ role as a “safety net,” suggesting they will help Bob control his powers in Doomsday. This aligns with the film’s post-credits scene, which confirms the Thunderbolts’ evolution into the New Avengers, with a message stating, “The New Avengers and Bob will return.” Pullman’s comments to Comicbookmovie.com further emphasize Sentry’s value, stating, “The Thunderbolts don’t want to let him out of their sight, because they realize that if he’s caught in the wrong hands, he might be dangerous.” This hints at Sentry being a key ally against Doctor Doom, whose reality-warping abilities pose a multiversal threat.

Sentry’s comic book history, created by Paul Jenkins and Jae Lee in 2000, provides clues about his MCU trajectory. In the comics, Bob Reynolds is a forgotten hero who erased himself from the world’s memory to thwart The Void, his repressed persona. His immense power, rivaling Thor and Captain Marvel, makes him a game-changer, but his mental instability often leads to manipulation, as seen in storylines like Dark Avengers and Siege. The MCU appears to adapt this duality, with Thunderbolts* establishing Bob as a government-controlled asset before his Void persona spirals out of control. Insiders suggest that in Doomsday, Sentry’s power may be restrained to maintain high stakes, possibly with Bob hesitant to unleash his full abilities for fear of The Void’s return, mirroring Hulk’s arc in Avengers: Infinity War.

The Avengers: Doomsday cast, announced in a five-hour Marvel livestream, includes Pullman alongside Pugh, Stan, Harbour, Wyatt Russell (John Walker), and Hannah John-Kamen (Ghost), with notable absences like Olga Kurylenko’s Taskmaster, hinting at her potential death in Thunderbolts*. The ensemble also features Chris Hemsworth (Thor), Anthony Mackie (Captain America), and Vanessa Kirby, facing Downey’s Doctor Doom. Pullman learned of his Doomsday role through co-star Danny Ramirez, who left “30 missed calls” to share the news, as reported by Deadline. His excitement is palpable, telling GamesRadar+, “It’s like breaking open a whole new room,” though he admitted to having “no idea” about specific plot details due to Marvel’s secrecy.

Fans on X are thrilled, with posts praising Pullman’s dedication—Florence Pugh noted his intense physical prep for Sentry—and speculating about his clash with Doom. Some theorize Sentry could be manipulated by Doom, echoing comic arcs, while others see him as a tragic hero who might sacrifice himself, as in Siege. With Thunderbolts* earning acclaim as a “beast” of a film, per early reviews, Sentry’s role in Doomsday promises to elevate the MCU’s multiversal saga, blending raw power with emotional depth.
