Marvel’s upcoming ensemble brings together fan favorites, redeemed villains, and unpredictable wild cards for a high-stakes mission.

Meet the Anti-Hero Team

December 4, 2025: Marvel Studios’ Thunderbolts** unites some of the MCU’s most complicated characters—and the cast lineup is one of the strongest ensembles Marvel has assembled in years. Blending returning heroes, reformed villains, and morally gray operatives, the film follows a government-backed team sent on dangerous missions no traditional superhero could handle.

Below is a guide to who plays who in the highly anticipated anti-hero entry.

Florence Pugh as Yelena Belova

Yelena returns as the sharp, witty, and deadly assassin fans grew to love in Black Widow and Hawkeye. As Natasha Romanoff’s sister and a former Red Room operative, she brings both emotional depth and unmatched combat skills—making her one of the unofficial leaders of the squad.

Sebastian Stan as Bucky Barnes / The Winter Soldier

Bucky steps back into the fray as the most seasoned member of the team. Still grappling with the trauma of his past, he serves as the reluctant moral center of the Thunderbolts, balancing experience, vulnerability, and unshakeable resolve.

David Harbour as Alexei Shostakov / Red Guardian

Charismatic, loud, and endlessly entertaining, Red Guardian brings brute strength and chaotic energy to the team. As Yelena’s father figure, his familial dynamics add humor—and sometimes tension—to mission operations.

Wyatt Russell as John Walker / U.S. Agent

Once a controversial replacement for Captain America, John Walker now serves under the government’s supervision as a hyper-focused, intensely driven combat operative. His unpredictable temper and need for redemption make him one of the team’s most volatile assets.

Hannah John-Kamen as Ava Starr / Ghost

With phasing abilities caused by quantum instability, Ghost returns as one of the MCU’s most unique fighters. Her desire for stability and purpose sets the stage for compelling growth within the group.

Olga Kurylenko as Antonia Dreykov / Taskmaster

Taskmaster’s photographic reflexes make her a formidable addition to the Thunderbolts. After the events of Black Widow, Antonia’s journey toward reclaiming her identity adds emotional complexity to her sharp-edged combat skills.

Julia Louis-Dreyfus as Valentina Allegra de Fontaine

Valentina orchestrates the team from behind the scenes. Calculated, strategic, and morally opaque, she shapes the Thunderbolts’ missions with motives that may not always align with the team’s best interests.

Lewis Pullman as The Sentry (Rumored/Reported)

Pullman is widely reported to play one of Marvel’s most powerful—and dangerous—characters: The Sentry. With god-like strength paired with a fractured psyche, his involvement could introduce massive stakes and unpredictable consequences.

A Team Unlike Any Other

With anti-heroes, former villains, and emotionally complex characters all thrown together, Thunderbolts** promises a darker, more morally ambiguous chapter of the MCU. The chemistry among the cast—paired with high-stakes action and layered storytelling—positions the film as one of Marvel’s most compelling ensemble projects.
