Thunderbolts

Part 1: The Dossier: An At-a-Glance Summary

Part 2: Origin and Evolution

Publication History and Creation

The Thunderbolts made their surprise first appearance in a cameo in The Incredible Hulk #449 in January 1997, before their full, shocking debut in Thunderbolts #1 in April 1997. The team was co-created by writer Kurt Busiek and artist Mark Bagley. The timing of their creation was a stroke of strategic genius. In the aftermath of the 1996 Onslaught crossover event, the world believed the Avengers and the Fantastic Four were dead, leaving a massive power vacuum in the superhero community. Busiek and Bagley capitalized on this void, presenting the Thunderbolts as a fresh, exciting team of new heroes stepping up to fill the void. The marketing for the series gave no hint of the team's true nature. The final page of Thunderbolts #1 delivered one of the most celebrated plot twists in modern comics: the revelation that these new heroes were, in fact, the long-established Masters of Evil, led by Baron Helmut Zemo. This reveal was a critical and commercial success, hooking readers and establishing the series' central theme of identity and the potential for redemption. The series became a cult classic, praised for its deep character development, particularly of previously C-list villains like Screaming Mimi (Songbird) and the Beetle (Mach-I through Mach-X), transforming them into complex, compelling figures.

In-Universe Origin Story

Earth-616 (Prime Comic Universe)

The in-universe origin of the Thunderbolts is a masterwork of deception orchestrated by the brilliant and ruthless Baron Helmut Zemo. Following the apparent deaths of the Avengers and Fantastic Four at the hands of Onslaught, Zemo recognized a unique opportunity. The world was terrified and leaderless, desperate for new champions to protect them. Zemo realized that the quickest path to ultimate power was not through overt conquest, but through seduction. If he could win the world's trust, he could gain access to the highest levels of global security, including S.H.I.E.L.D. and the United Nations, from which he could enact his true plan for world domination. To this end, Zemo reassembled his latest incarnation of the Masters of Evil with a bold new directive: they would become the heroes the world needed. Each member adopted a new heroic persona:

Operating from a secret mountain headquarters, the Thunderbolts made a spectacular public debut, saving New York from a Wrecking Crew attack and other threats. The public and the media embraced them wholeheartedly. They were the perfect answer to the world's prayers. However, the plan began to fray from within. Characters like Abe Jenkins, Melissa Gold, and Erik Josten discovered they genuinely enjoyed the public's adoration and the feeling of doing good. The act of playing heroes started to feel more real than their past lives as villains. This internal conflict, between Zemo's unyielding plan for conquest and his team's growing desire for true redemption, became the central driving force of their initial saga. The schism ultimately fractured the team, forcing each member to choose between their villainous past and a potential heroic future.

Marvel Cinematic Universe (MCU)

The origin of the Thunderbolts in the Marvel Cinematic Universe is a starkly different, more grounded, and politically charged affair. There is no element of villains masquerading as heroes; instead, the team is being assembled as a government-controlled asset composed of known, morally complex individuals. The architect of this team is the mysterious and formidable Contessa Valentina Allegra de Fontaine. The seeds of the team were planted across several Phase Four projects:

The team's official roster for the upcoming film Thunderbolts* (2025) has been confirmed to include:

The team's name carries a significant thematic weight in the MCU. For years, the primary antagonist of the Hulk was General Thaddeus “Thunderbolt” Ross. In Captain America: Brave New World, Ross will have become the President of the United States. It is heavily implied that this team is his initiative, a state-sanctioned weapon to project American power in a post-Avengers world. Unlike Zemo's team, the MCU Thunderbolts are not a deception; they are a tool of statecraft, composed of individuals with checkered pasts who are deemed expendable or, at the very least, deniable. Their origin is not about fooling the public, but about the government harnessing powerful, morally ambiguous assets for its own ends.

Part 3: Mandate, Structure & Key Members

Affiliations

The Thunderbolts have a complex history with various official bodies. They have been both fugitives from and sanctioned agents of the United States government. Their relationship with the Commission on Superhuman Activities (CSA) was central to Hawkeye's era, with the CSA acting as their parole officers. Under Osborn, they became the primary enforcement arm of The Initiative. They have frequently come into conflict with the Avengers, who have often viewed them with suspicion, but have also worked alongside them when global threats demanded it. Their home base has shifted from a remote mountain stronghold to the super-max prison, The Raft, highlighting their ever-changing status in the world.

Part 5: Iconic Events & Storylines

"Justice, Like Lightning..." (Thunderbolts #1-12)

This is the foundational storyline that established the team. It details Baron Zemo's brilliant plan, the formation of the team as the Masters of Evil in disguise, and their celebrated public debut. The arc's genius lies in how it fully commits to the heroic facade, making the reader believe in these new heroes right alongside the in-universe public. The drama builds as team members like Songbird and MACH-I begin to prefer their new lives, leading to simmering conflict with the unwavering Zemo. The climax, where the truth is revealed to the world upon the return of the real Avengers, shatters the team's public image and forces them to go on the run, cementing their status as Marvel's most compelling anti-heroes.

The Fight for Redemption (Hawkeye's Leadership)

This era, primarily helmed by writer Fabian Nicieza, defined the soul of the Thunderbolts. After ousting Zemo, the remaining members sought a legitimate pardon and turned to Hawkeye, a hero with a criminal past, to lead them. This storyline saw the team desperately trying to prove their heroic intentions while being hunted by both law enforcement and Zemo's new Masters of Evil. Hawkeye's tough-love leadership forged them into a true team, and their constant struggle against public perception and their own past sins was a powerful, character-driven narrative that elevated them beyond their initial gimmick.

The Osborn Regime (Thunderbolts #110-127)

Written by Warren Ellis, this storyline represented a dark and cynical turn for the concept. Now government-sanctioned killers under Norman Osborn, the team's missions were brutal, morally bankrupt, and often involved assassinating targets deemed threats to Osborn's agenda. Ellis used the series as a political satire, showcasing a team of monsters (including a cannibalistic Venom and the psychopathic Bullseye) being cynically deployed by an even bigger monster. Songbird's desperate attempts to hold the team's soul together from within provided a sliver of hope in an otherwise grim and violent saga that perfectly captured the dark tone of the post-Civil War era.

The Raft Program (Luke Cage's Leadership)

Under Jeff Parker, the Thunderbolts concept was rebooted again. Now operating out of the Raft, the team was a super-powered chain gang. The core of the story was the volatile chemistry between the members—Juggernaut, Crossbones, Ghost, Moonstone, and Man-Thing—and their warden, Luke Cage. The missions were often bizarre, involving time travel and interdimensional threats, but the central conflict remained grounded: can you force people to be good? This era explored the ethics of rehabilitation and coercion, with Cage constantly struggling to keep his dangerous charges in line while offering them a sliver of hope for a better life.

Notes and Trivia

1) 2) 3) 4) 5)

1)
The original codenames and appearances for the Thunderbolts were intentionally designed by Kurt Busiek and Mark Bagley to evoke archetypes of classic heroes, helping to sell the deception to both readers and the Marvel Universe public. Citizen V was a stand-in for Captain America, Atlas for Goliath/Giant-Man, Meteorite for Captain Marvel, and MACH-I for Iron Man.
2)
The grand reveal in Thunderbolts #1 is consistently ranked by critics and fans as one of the greatest comic book plot twists of all time, on par with moments like the reveal of the Winter Soldier's identity or the conclusion of Watchmen.
3)
The MCU's direct linking of the team's name to Thaddeus “Thunderbolt” Ross is a deliberate creative choice that streamlines the team's thematic purpose. In the comics, while a “Thunderbolt” army unit led by Ross existed, the superhero team's name was chosen by Zemo for its dramatic flair, not as a direct homage to the General.
4)
Source Material: The original concept and twist are from Thunderbolts #1 (1997). Hawkeye's leadership begins in earnest in Thunderbolts #21 (1998). Norman Osborn's takeover begins in Thunderbolts #110 (2007). Luke Cage's program starts in Thunderbolts #144 (2010).
5)
The character of Songbird (Melissa Gold) is often cited as the team's greatest success story. She evolved from a minor, one-note villain (Screaming Mimi) into a complex, capable, and genuinely heroic leader, eventually becoming an Avenger. Her journey embodies the core promise of the Thunderbolts concept.
