The Marvel Cinematic Universe has officially welcomed one of its most powerful characters yet. After months of speculation and a lot of mystery, the newest ‘Thunderbolts*’ international trailer has finally confirmed what fans have been theorizing for a long time.
Lewis Pullman is indeed playing Sentry, and he’s about to shake up the MCU in ways we’ve never seen before. However, his inclusion also raises questions.
‘Thunderbolts*’ Trailer Finally Showcases Sentry’s Long-Awaited Reveal

The new ‘Thunderbolts*’ footage does more than just ramp up anticipation, it drops a major reveal that could redefine the power hierarchy of the MCU. “Bob,” the quiet mystery man teased in previous trailers, is no longer a question mark. He is Sentry. And according to the narration, he’s stronger than all of the Avengers combined.

For fans familiar with the comics, Sentry’s arrival is a game-changer. Known in the pages of Marvel lore as Robert Reynolds, Sentry is a character who lives in a perpetual tug-of-war between light and darkness. He is imbued with the power of “a million exploding suns” and haunted by his alter ego, The Void. He’s not your average superhero. He’s complex, unstable, and immensely powerful.
So, bringing him into the MCU is both a bold and exciting move. What makes this reveal even more tantalizing is how Marvel has slowly built it up. For months, trailers and promos danced around Pullman’s identity, showing fleeting glimpses of glowing eyes or dark silhouettes. Fans speculated wildly. Was this really Sentry? Was Marvel hiding something bigger? The clues were all there.
Now, the studio has pulled back the curtain just enough to confirm it. The international trailer doesn’t give everything away, it still leaves a great deal to the imagination. However, it delivers enough to confirm that Sentry is a force to be reckoned with. His glowing eyes hint at the explosive energy that lies within him. The narration calls him “Earth’s Mightiest Hero.” Additionally, the context suggests he might just be Earth’s biggest threat.
What Sentry’s Debut Means For The Future Of The MCU

The confirmation of Sentry in ‘Thunderbolts*’ has massive implications, not just for the movie itself, but for the entire MCU moving forward. This isn’t a minor introduction. Marvel has already confirmed that Sentry will appear in ‘Avengers: Doomsday’, meaning he’s not a one-and-done character. He’s being positioned as a central figure in the transition from Phase 5 to Phase 6 of the Multiverse Saga.

And Marvel’s decision to wait until a month before ‘Thunderbolts*’ hits theaters is something that Marvel has done before to build anticipation. Much like the way fans buzzed about the possible returns of Tobey Maguire and Andrew Garfield in ‘Spider-Man: No Way Home’, the mystery surrounding Pullman’s character has built a slow-burning excitement. Now that the reveal is official, the hype is only going to grow.
However, that excitement comes with big questions. How will the ‘Thunderbolts*’, a team of antiheroes and government-sanctioned operatives, deal with someone who could easily overpower them all? What is Sentry’s role in this film, hero, villain, or something in between? And perhaps most importantly, what’s his connection to The Void?
