Marvel's upcoming Thunderbolts film remains largely mysterious, but a recent Big Game trailer offers a glimpse into the MCU team-up. While plot details remain scarce, the trailer provides a clearer look at Lewis Pullman as Bob Reynolds, aka The Sentry. This Superman-esque hero's MCU debut promises significant ramifications.
Who is The Sentry, and why is he both the Marvel Universe's greatest champion and its most terrifying threat? Let's explore this mentally unstable hero's history and his potential role in Thunderbolts.
The Sentry: Marvel's Most Powerful, Most Dangerous Hero
The Sentry possesses arguably the most potent abilities in the Marvel Universe, yet he's equally dangerous. Once an ordinary man, Bob Reynolds, he consumed a serum granting him "the power of a million exploding suns." This power, however, comes at a terrible price: The Void, a dark, malevolent alter ego. For every good deed The Sentry performs, The Void commits an equally evil act. Bob Reynolds' struggle against his inner darkness is a constant, losing battle. Yet, when a powerful hero is needed, none are better suited than The Sentry.
The Sentry's Abilities and Powers
The Sentry's abilities originate from an experimental serum, a post-WWII attempt to replicate the Super Soldier Serum. This serum reportedly accelerates his molecules forward in time. Consequently, The Sentry boasts incredible strength rivaling the Hulk and Thor, flight, super-speed, enhanced senses, and near invulnerability. He can also absorb and project energy, enabling feats like energy blasts, teleportation, and subduing the Hulk. In terms of power, The Sentry is Marvel's answer to Superman.
The Void, however, is arguably even more formidable. A shapeshifting, demonic entity, The Void controls weather patterns, invades minds, and has withstood the combined forces of the Avengers, X-Men, and Fantastic Four. Even banishment to the sun proves only a temporary solution.
The Sentry's Secret Origin and Avenger Status
Created by Paul Jenkins, Rick Veitch, and Jae Lee, The Sentry debuted in 2000. Initially presented as a forgotten hero, even Bob Reynolds initially lacked memory of his past as "The Golden Guardian of Good." Upon regaining his memories, he confronts The Void's return. The Sentry's history with characters like the Hulk and Fantastic Four is retroactively integrated into Marvel continuity.
The Sentry and The Void are revealed as two sides of the same coin. The world's collective memory of The Sentry was suppressed to protect it from The Void. Bob repeats this act to contain his dark side, ambiguously erasing the world's knowledge of The Sentry, leaving his own memory uncertain.
The Sentry's role expanded beyond his initial miniseries, becoming a New Avenger in 2004. He joined a revamped team alongside Spider-Man, Wolverine, and Luke Cage, initially a reluctant participant. Despite his power, he continually battles to maintain sanity and control The Void.
During the Civil War, he sided with Iron Man's pro-registration faction, understanding the dangers of unchecked power. He played a crucial role against the Hulk in World War Hulk. However, his downfall began in Dark Reign (2009), manipulated by Norman Osborn into joining the Dark Avengers, alongside villains like Bullseye and Venom.
The Void's full unleashing occurred during Siege (2010), culminating in The Sentry's death. Subsequent resurrections and deaths have followed, with ongoing exploration of his powers and the true nature of his dual identity. His most recent death occurred in 2020's King in Black. Marvel's 2023 The Sentry series explores a new host for his power, raising questions about the future of both The Sentry and The Void.
The Sentry's Role in Thunderbolts
Beyond appearances in Marvel mobile games, The Sentry's MCU debut in Thunderbolts marks a significant moment. Lewis Pullman portrays the Golden Guardian of Good, though initially Steven Yeun was cast but had to withdraw due to scheduling conflicts and the film's delayed release.
The Sentry's precise role in Thunderbolts remains unclear. Given his comic book history, he'll likely be depicted as both a powerful hero and a terrifying villain. Will he initially be a Thunderbolt, only to become their greatest threat? His presence significantly elevates the stakes for the team.
Contessa Valentina Allegra de Fontaine might play a role similar to Norman Osborn's, exploiting The Sentry's power before losing control. The Sentry might function as a Marvel equivalent to the Enchantress in Suicide Squad.
The film's handling of The Sentry's forgotten past and his Superman-esque nature remains to be seen. Further details will emerge as the May 2025 release date approaches.
