What Is Thunderbolts in the MCU?
Thunderbolts is Marvel Studios’ boldest team-up yet, released in May 2025 as the climactic film of MCU Phase 5. Unlike the Avengers, the Thunderbolts are a group of antiheroes—characters with checkered pasts, questionable motives, and a knack for breaking the rules. The cast of Thunderbolts plays a pivotal role in making this movie a standout addition to the MCU, as it brings together characters who have often operated on the fringes of heroism.
A Brief History of the Thunderbolts Team in Marvel Comics
The Thunderbolts first appeared in Marvel Comics in 1997, originally as a team of supervillains masquerading as heroes.
