The Sentry Rumor Points To Marvel Studios Having Some Bonkers Plans For The Void

Earlier this week, The Walking Dead and Invincible creator Robert Kirkman confirmed two big rumours when he revealed that Steven Yeun will don a comic-accurate costume as the MCU’s Sentry in Thunderbolts.

Today, an intriguing new report has surfaced which claims the movie will deliver an unexpected take on The Void.

Rather than just being the Golden Guardian’s evil doppelgänger, it seems the villain will become an entire realm which the movie’s heroes are forced to travel into. That sounds like the sort of CG-heavy high-stakes final act we’ve come to expect from Marvel Studios, and it wouldn’t be at all surprising if not everyone makes it back alive.

Back in September, it was reported that The Sentry is initially going to be part of Val’s Thunderbolts team during the first two acts before “something rips him away from them.” Could that be this new manifestation of The Void? We’d say it’s likely.

Thunderbolts is shaping up to be a much different movie than than what fans initially expected. Despite featuring a roster that suggests the movie is primarily a sequel to Black Widow and The Falcon and The Winter Soldier, The Sentry’s presence suggests this story will have major ramifications for the wider MCU.

Fingers crossed The Void looks better than the Quantum Realm, anyway! 

In the comics, Steve Rogers was initially the only person the Super Soldier Serum worked on. Other government agencies struggled to create their own versions, and it was in the late 1940s that Project: Sentry was first dreamed up.

Meant to be 100,000 more powerful than the serum that created Captain America, the project ultimately got bogged down in red tape. However, years later, a meth addict called Robert Reynolds broke into the laboratory of one of the professors who worked on that and ingested the “Golden Sentry Serum” while looking for a fix.

With that, he gained the power of a million exploding suns, later becoming one of the Marvel Universe’s greatest superheroes. There was a twist, though, as The Void – Reynolds’ repressed personality – later emerged and took the form of a shadowy monster every bit as powerful as the Golden Guardian. It killed millions and continued to plague The Sentry in the years that followed.

Thunderbolts‘ confirmed cast members include Julia Louis-Dreyfus as Valentina Allegra de Fontaine, Florence Pugh as Yelena Boleva, Sebastian Stan as Bucky Barnes, David Harbour as Red Guardian, Wyatt Russell as U.S. Agent, Hannah John-Kamen as Ghost, Olga Kurylenko as Taskmaster, and Steven Yeun in a mystery role now confirmed to be The Sentry.

Written by Eric Pearson and directed by Jake Schreier, Thunderbolts is currently set to be released in theaters on July 25, 2025.
