Doomsday Sentry look confirms the Thunderbolts costume

LEGO's first Avengers: Doomsday Sentry minifigure confirms Lewis Pullman returns in the same yellow-and-blue Thunderbolts costume designed by Valentina Allegra de Fontaine—not a new suit. The October 4 New Avengers Tower set finally shows Bob Reynolds suited up again after sitting out Void risks.

Key Takeaways

• LEGO's Avengers: Doomsday "New Avengers Tower" set, launching October 4, debuts the first official Sentry minifigure.
• The figure keeps Bob Reynolds in the corporate yellow-and-blue Thunderbolts look, not a redesigned Doomsday costume.
• Thunderbolts* introduced Sentry (Lewis Pullman) via O.X.E. Group experiments that also unleashed The Void.
• Doomsday's trailer keeps Sentry sidelined while the New Avengers meet Thor, Ant-Man, Captain America, and the Fantastic Four.
• Insider reporting and set leaks point to a major, emotionally charged Sentry arc against Robert Downey Jr.'s Doctor Doom.

For fans who left the theater after Thunderbolts* already guessing Bob would suit up again, the wait is over. Marvel's toy partner has done what the first Avengers: Doomsday trailer would not: put Sentry back in the yellow and blue in plain sight. That reveal lands squarely in the Nostalgia: Then & Now lane—same hero, same suit, bigger Multiverse stakes.

What does the Doomsday Sentry LEGO figure actually confirm?

According to The Direct, LEGO's first wave of buildable Avengers: Doomsday sets includes "New Avengers Tower," the skyscraper that first appeared in Thunderbolts*. The set's headline piece is the first-ever Sentry minifigure, which doubles as the clearest public look yet at how Bob returns for the Multiversal conflict.

The costume itself is the confirmation fans expected. Like much of Doomsday's cast with recent MCU appearances, Sentry does not appear to be getting a brand-new superhero redesign for his 2026 return. Based on the LEGO figure, he is still wearing the same suit from Thunderbolts*—the corporate, PR-driven look Valentina Allegra de Fontaine put together.

That continuity matters. Marvel Studios has assembled seven god-tier characters to face Robert Downey Jr.'s Doctor Doom, and Sentry ranks among the strongest figures already introduced in the Multiverse Saga. Keeping the Thunderbolts look signals that Bob's next chapter builds directly on the team, tower, and trauma audiences already know.

Fans actually glimpsed Bob's comeback earlier. The Thunderbolts* post-credits scene was ripped from Doomsday's first act, showing Bob after 14 months without suiting up as Sentry. LEGO's Doomsday wave unsurprisingly confirms he will get back into the yellow and blue when the conflict demands it.

Why is Sentry staying on the sidelines in Avengers: Doomsday?

Doomsday's first trailer appears to pick up right after that post-credits beat, with Sentry still firmly on the bench. The reason is Void management: Bob's power came with The Void, a physical, terrifying embodiment of his trauma. Keeping him sidelined is framed as a way to avoid Void-related risks while the larger team mobilizes.

Even without the full Sentry transformation, Bob is already in the room. The New Avengers—including Bob—were spotted meeting with Thor, Ant-Man, Captain America, and the Fantastic Four as the God of Thunder delivered a speech about the looming threat. The trailer hid the costumed Sentry; LEGO shows no such restraint.

The toy set seemingly depicts the New Avengers and the Fantastic Four's Human Torch fighting Doctor Doom around the New York skyscraper. That image alone suggests Bob will not stay benched forever. When he does suit up, the figure implies it will be the familiar Thunderbolts armor stepping into an Avengers-scale battle.

Power-wise, Thunderbolts* already established Sentry as an all-powerful force: superstrength, superspeed, superhuman durability, flight, and the ability to manipulate the world around him. What was missing on screen then was his comic-book golden energy—the power of a million exploding suns. The Direct notes that ability seems to be on full display in Doomsday.

Could Sentry become one of Doomsday's biggest game-changers?

Possibly—and that is the real reason the costume confirmation lands with such force. Insider Daniel Richtman previously declared that Lewis Pullman's Sentry will be among the MVPs of Avengers: Doomsday. Whenever Bob is forced off the sidelines and uses his immense power, the reporting suggests he could turn the tide of the coming conflict.

There are also signs his second arc may carry real emotional weight, not just spectacle. A Doomsday set leak last year hinted at a visit to Bob's mother's home, where audiences may learn more about his troubled upbringing as a child of domestic abuse. That backstory would deepen why the Void's devastation in New York left Bob terrified to use his power again.

In the New Avengers, Bob has finally found a family. The Direct argues it will likely be seeing one or all of them in mortal danger that prompts him to go all-out Sentry—possibly with a dramatic entrance timed like Thor's Wakanda arrival in Avengers: Infinity War.

His closest bond in Thunderbolts* was with Florence Pugh's Yelena Belova, who led the charge in saving him from his own mental health crisis. One speculative path has Yelena on the cusp of death at Doctor Doom's hands before Sentry enters the fight. During the Thunderbolts post-credits scene, David Harbour's Red Guardian even dreamt of riding upon Sentry into an epic battle—a gag the Russo Brothers could still pay off for laughs and catharsis.

Avengers: Doomsday is set for theaters on May 1, 2026. Until then, the LEGO Sentry figure is the clearest proof that the Thunderbolts era is not a side quest: Bob Reynolds is coming back in the suit fans already recognized—and Marvel is banking on that continuity to make his Doomsday moment hit harder.
