Thunderbolts

• Core Identity: The Thunderbolts are a premier Marvel super-team, most famously beginning as a cadre of supervillains disguised as heroes, who have since evolved through numerous incarnations, often serving as a government-sanctioned redemption program or a black-ops squad for morally ambiguous missions.
• Key Takeaways:
• A Legacy of Deception and Redemption: The team's defining characteristic is its origin as Baron Zemo's Masters of Evil in disguise, a plot to gain global power that backfired when most members developed a taste for genuine heroism. This central theme of redemption, identity, and the struggle against one's own nature remains a constant throughout their history.
• The Government's Double-Edged Sword: Following the events of Civil War, the Thunderbolts were institutionalized as a government tool. They have functioned as enforcers of the Superhuman Registration Act, a “second chance” program for incarcerated villains under Luke Cage, a covert wet-works team under The Winter Soldier, and a private army for corrupt officials like Norman Osborn and Wilson Fisk.
• Comic Canon vs. MCU Adaptation: In the Earth-616 comics, the Thunderbolts were born from the power vacuum left by the apparent deaths of the Avengers and Fantastic Four. In the Marvel Cinematic Universe (MCU), they are being assembled by the enigmatic Contessa Valentina Allegra de Fontaine as a proactive government-backed team of anti-heroes and assets with checkered pasts, serving a similar but distinct narrative purpose in a post-Endgame world.

The Thunderbolts made their first, unheralded appearance in The Incredible Hulk #449 (January 1997), created by writer Kurt Busiek and artist Mark Bagley. Their dramatic and full introduction occurred one month later in their own self-titled series, Thunderbolts #1 (April 1997). The team's creation was a direct response to the major comic event of the era, Onslaught. In that storyline, the majority of Earth's most prominent heroes, including the Avengers and the Fantastic Four, sacrificed themselves to defeat the titular psychic entity. This left the Marvel Universe in a state of shock and grief, with a notable absence of its greatest champions. Busiek seized this narrative opportunity to explore a compelling question: “What happens when the villains have to step up and become the heroes?” The brilliance of the concept was concealed in one of modern comics' most famous twists. For the entirety of Thunderbolts #1, the reader is introduced to a new, exciting team of heroes filling the void. It is only on the final page that the team's leader, Citizen V, unmasks to reveal he is, in fact, the notorious Nazi supervillain Baron Helmut Zemo. The entire team was his restructured Masters of Evil in disguise. This reveal sent shockwaves through the comic book community, establishing the series as a must-read and cementing its place in Marvel history. The initial run, primarily helmed by Busiek and later Fabian Nicieza, is critically acclaimed for its deep character work, exploring whether true redemption is possible for those who have committed heinous acts.

The circumstances of the team's formation differ significantly between the primary comic continuity and the cinematic universe, though both tap into the core idea of filling a power vacuum with morally compromised individuals.

Following the catastrophic battle with Onslaught in Central Park, New York, the world believed the Avengers and Fantastic Four were dead. This created an unprecedented crisis of faith and a massive gap in global security. Baron Zemo, a strategic genius and a bitter foe of Captain America and the Avengers, saw this not as a tragedy, but as the ultimate opportunity. His plan was audacious and layered. Rather than attempting a frontal assault on a world on high alert, he would win its trust. He reassembled key members of his fourth incarnation of the Masters of Evil and gave them new, heroic identities, complete with redesigned costumes and fabricated backstories. His goal was to have the Thunderbolts acclaimed as the world's new premier super-team, granting them access to the highest levels of global security infrastructure, including S.H.I.E.L.D. and Avengers Mansion files, which he could then use for world domination. The original roster was a carefully selected group of his most loyal (and powerful) followers:

• Goliath (Erik Josten) became Atlas, the team's super-strong powerhouse.
• Screaming Mimi (Melissa Gold) became Songbird, now with a more sophisticated vocal harness that created solid-sound constructs.
• The Beetle (Abner Jenkins) became MACH-I, a high-tech armored hero, ostensibly a rookie trying to live up to the legacy of Iron Man.
• The Fixer (Paul Norbert Ebersol) became Techno, the team's reclusive technology expert.
• Moonstone (Dr. Karla Sofen) became Meteorite, the team's compassionate and powerful public face.
• Baron Zemo (Helmut Zemo) himself took on the mantle of Citizen V, a legacy hero name once used by a WWII freedom fighter his father had killed.

The plan was a resounding success. The public, desperate for heroes, embraced the Thunderbolts wholeheartedly. The problem Zemo hadn't anticipated was psychological. For members like Melissa Gold, Abner Jenkins, and Erik Josten, the public adoration and the genuine good they were accomplishing was intoxicating. They found they preferred being heroes. When Zemo was ready to enact his final gambit and reveal their true identities, the majority of the team, led by Songbird and Atlas, rebelled against him. With the help of the newly-returned Avengers, they defeated Zemo, but became fugitives in the process—villains to the heroes, and traitors to the villains. This act of defiance marked the true birth of the Thunderbolts as a team dedicated, however clumsily, to the path of redemption.

The origin of the Thunderbolts in the MCU is a gradual, more clandestine affair, orchestrated in the shadows of major global events. Their formation is not a direct result of a single cataclysm like Onslaught, but rather the culmination of a changing political landscape following the Blip and the dissolution of the original Avengers. The architect of this team is Contessa Valentina Allegra de Fontaine, a mysterious and well-connected operative with ties to the CIA and a murky agenda. Operating in the power vacuum left by the death of Tony Stark, the retirement of Steve Rogers, and the fracturing of the Avengers, Valentina began recruiting a specific type of asset: powerful individuals with questionable morals, past traumas, or government-forged identities who could be easily manipulated and deployed for missions that fall outside public scrutiny and the bounds of the Sokovia Accords. Her recruitment process has been shown across multiple films and series:

• She first approached John Walker after he was publicly disgraced and stripped of the title of Captain America, rebranding him as U.S. Agent and giving him a purpose for his rage. (The Falcon and The Winter Soldier)
• She tasked Yelena Belova, the sister of the late Natasha Romanoff, with assassinating Clint Barton, falsely framing him for her sister's death. (Black Widow)
• By 2025, she had been appointed the Director of the CIA and continued to assemble her team, bringing in established figures like Bucky Barnes (The Winter Soldier), Ava Starr (Ghost), Antonia Dreykov (Taskmaster), and Alexei Shostakov (Red Guardian).

The MCU's Thunderbolts are not villains pretending to be heroes for a public stunt. They are a government-sanctioned special-ops team composed of anti-heroes, former assassins, and super-soldiers. Their mandate, while not yet fully revealed, appears to be a proactive and potentially ruthless response to global threats, functioning as a darker, more pragmatic alternative to the Avengers. The reasons for this adaptation are rooted in the existing MCU narrative: the characters chosen were already established, their recruitment logically follows the world's growing distrust of unsanctioned superheroes, and their formation directly addresses the question of who protects the world when the Avengers are gone.

The team's purpose, leadership, and roster have been in a near-constant state of flux in the comics, reflecting the evolving moral landscape of the Marvel Universe. The MCU version, by contrast, is being established with a clearer, more focused initial purpose.

The Thunderbolts' mission statement has changed dramatically with each new leader and political climate.

• Zemo's Era (Deception): The original mandate was a lie. Publicly, they were there to provide hope and security. Privately, they were a tool for world conquest.
• Hawkeye's Era (Legitimacy): After becoming fugitives, the team was taken over by the Avenger Hawkeye, who believed in their potential for redemption. As a former criminal himself, he sought to grant them full pardons by leading them as a legitimate force for good, often clashing with his former Avengers teammates who distrusted the group.
• Osborn's Era (Enforcement): During the aftermath of Civil War, the Thunderbolts program was co-opted by the U.S. Government and placed under the command of Norman Osborn. Their mandate became brutal and simple: hunt down and capture or neutralize unregistered superheroes. The team was composed of dangerous, often unhinged supervillains like Venom (Mac Gargan), Bullseye, and Penance, controlled via nanite inhibitors. This was the darkest incarnation of the team, essentially a government-sanctioned hit squad.
• Luke Cage's Era (Rehabilitation): During the Heroic Age, the program was reformed under Luke Cage's leadership and based out of The Raft super-prison. Its mandate shifted to rehabilitation. Villains were offered a chance at reduced sentences or freedom by serving on the team for high-risk missions, with Cage acting as their moral compass. This era explored whether even the most hardened criminals could be given a second chance.
• Winter Soldier's Era (Covert Ops): Bucky Barnes, as the Winter Soldier, later led a small, off-the-books Thunderbolts team with a proactive mandate: to eliminate threats to Earth before they could emerge. This was a black-ops team operating in the shadows, far from public view.
• Fisk's Era (Authoritarian Control): As the Mayor of New York City, Wilson Fisk (the Kingpin) outlawed vigilantism and commissioned his own Thunderbolts team. Their mandate was to enforce his law by brutally hunting down the city's heroes, including Spider-Man and Daredevil. This version brought the team full circle, once again making them villains in the public's eye, but this time with the law on their side.

The Thunderbolts' roster is one of the most extensive and varied in Marvel Comics. The table below highlights some of the most significant members throughout its history.

The MCU Thunderbolts' mandate is to be a government-controlled and accountable strike force. In a world where the Avengers operated with autonomy—a key point of contention leading to the Sokovia Accords—the Thunderbolts represent the opposite: a team of super-powered assets on a government leash. Their likely missions will be those deemed too politically sensitive, morally grey, or dangerous for public-facing heroes. This could include covert infiltrations, assassinations, and retrieval of dangerous technology. They are a scalpel (or a sledgehammer) to be wielded by figures like Valentina de Fontaine to protect American interests and project power globally.

• Director: Contessa Valentina Allegra de Fontaine is the undisputed founder and director. She is the MCU's equivalent of Nick Fury, but with far more ambiguous morals and a cynical worldview. She handles recruitment, provides a mission, and pulls the strings from behind the scenes.
• Field Leadership: The team's internal command structure is currently unknown. It is likely to be a source of major conflict. Both Bucky Barnes and John Walker have extensive military command experience, but their vastly different ethical codes and temperaments will almost certainly lead to a power struggle. Yelena Belova, a highly trained spy, could also emerge as a pragmatic leader.

• Yelena Belova (Black Widow): A product of the Red Room, she possesses the same elite espionage and combat skills as her adoptive sister, Natasha Romanoff. She brings a cynical wit and deadly efficiency to the team but also a buried sense of morality.
• Bucky Barnes (The Winter Soldier): A super-soldier with a century of combat experience, a cybernetic arm, and immense psychological trauma. He is likely the team's moral center, struggling to atone for his past as a HYDRA assassin while being pulled back into a world of black-ops.
• John Walker (U.S. Agent): A highly decorated soldier who was granted a variant of the Super Soldier Serum. He is physically powerful but mentally unstable and desperate for validation. He represents the jingoistic, “mission-first” ideology that will clash with Bucky's more humanistic approach.
• Antonia Dreykov (Taskmaster): A victim of the Red Room with photographic reflexes, allowing her to mimic any physical action she sees. Once a mindless weapon under her father's control, she is now free, but her psychological state and allegiances are unknown.
• Ava Starr (Ghost): A former S.H.I.E.L.D. operative afflicted with “molecular disequilibrium,” allowing her to phase through solid objects. She is not inherently evil, but a desperate individual seeking a cure. The government likely holds the technology to stabilize her condition, giving them leverage.
• Alexei Shostakov (Red Guardian): The Soviet Union's first and only super-soldier. While past his prime, he possesses peak human strength and durability. He primarily provides comic relief and brute force but has a deep-seated desire to be seen as a legitimate hero.

• Hawkeye (Clint Barton): In the comics, Hawkeye is arguably the Thunderbolts' most important ally. A former criminal himself, he saw their potential and took over the team to lead them towards true heroism. He risked his reputation and his relationship with the Avengers to give them a second chance, embodying the team's core theme of redemption.
• Luke Cage: As the leader of the Heroic Age Thunderbolts, Luke Cage was a firm but fair warden. He was not their friend, but he was their advocate, believing that the system could work and that people deserved a chance to earn their freedom. His unimpeachable moral character gave the program a legitimacy it had never had before.
• Captain America (Steve Rogers & Sam Wilson): The team's relationship with Captain America has always been complex. Zemo's obsession with him was the catalyst for their creation. Later, Steve Rogers came to respect certain members (like Songbird and MACH-I) but never fully trusted the group. This tension was amplified when Bucky, his best friend, led a version of the team.

• Baron Zemo: The team's creator is also their most persistent nemesis. Even when not directly opposing them, his shadow looms large. His original plan, his philosophy of superiority, and his manipulative genius are the things the team must constantly fight against, both externally and within themselves. He represents the past they can never truly escape.
• Norman Osborn: While Zemo created them, Osborn corrupted them. As director of the Thunderbolts Initiative, he twisted the concept of redemption into a tool for his own sadistic and power-hungry ambitions. He turned the team into monsters and assassins, forever staining their name and proving that the program could be used for immense evil.
• Their Own Pasts: The most profound enemy the Thunderbolts face is their own history. Every member is haunted by their past crimes, their insecurities, and the public's perception of them as villains. Their greatest battles are often internal, struggling with the choice between who they were and who they want to be.

• U.S. Government: The Thunderbolts have frequently been an official (or semi-official) branch of the United States government, operating under the authority of the Commission on Superhuman Activities (CSA). This relationship is always fraught, with the team being used as a political tool, often for missions the public could never know about.
• The Avengers: The Thunderbolts exist in the shadow of the Avengers. They were created to replace them, often fight them, sometimes work with them, and are perpetually judged against their standard of heroism. To the Avengers, the Thunderbolts are a constant, uncomfortable reminder of the blurred lines between hero and villain.
• S.H.I.E.L.D. & The Raft: In their government-sanctioned forms, the team has had deep operational ties to S.H.I.E.L.D. and was even based out of the Raft, the super-prison for super-powered criminals. This gave them access to resources but also kept them under tight control.

This is the foundational storyline that established the team and its core premise. For months, the Thunderbolts operate as the world's darlings, defeating threats and winning public adoration. The narrative expertly builds the characters, making the reader root for them as heroes. All the while, Zemo is secretly executing his plan. The climax occurs when the Avengers and Fantastic Four return. Zemo activates his master plan to brainwash the heroes, but his team, led by Songbird, MACH-I, and Atlas, having grown to love their new lives, refuse. They help the Avengers defeat Zemo, but in doing so, they are forced to reveal their true identities to the world. The story ends with them as wanted fugitives, setting the stage for their long journey toward redemption.

Following the passage of the Superhuman Registration Act, Iron Man and the pro-registration side needed a team to hunt down anti-registration heroes like Captain America. Norman Osborn, the supposedly “reformed” Green Goblin, was put in charge of a new Thunderbolts team. This roster was a collection of psychopaths and mercenaries, including Bullseye, Venom (Mac Gargan), and Lady Deathstrike, controlled by debilitating nanites. Their missions were brutal and bloody. This storyline, written by Warren Ellis, was a dark, satirical take on the “War on Terror,” showcasing the horrifying extremes a government would go to enforce its will. It was a critical and commercial success that repositioned the Thunderbolts as a major force in the Marvel Universe and led directly to Osborn's rise to power in the Dark Reign storyline.

After Osborn's fall, Steve Rogers and the new guard of heroes sought to reform the system. Luke Cage was appointed to lead a new Thunderbolts program based out of the Raft. The concept was simple: a chance at parole for serving on the team. This era, primarily written by Jeff Parker, brought back the theme of redemption to the forefront. The team included a fascinating mix of powerhouse villains (Juggernaut, Crossbones), morally ambiguous figures (Moonstone, Ghost), and forgotten heroes (Man-Thing). The series was praised for its focus on character dynamics, dark humor, and high-concept sci-fi adventures, such as time-traveling to fight Nazi versions of the Avengers.

When Wilson Fisk becomes Mayor of New York City, he uses his political power to enact a personal vendetta against the city's superheroes. He passes the “Powers Act,” making all non-sanctioned superhero activity illegal. To enforce this, he creates his own team of Thunderbolts, deputizing villains like Taskmaster, Rhino, and Doctor Octopus. This forces heroes like Captain America, Spider-Man, and Daredevil to go underground. Fisk's Thunderbolts act as his personal stormtroopers, turning New York into a police state. This storyline brings the Thunderbolts' name full circle, transforming them from fake heroes into legally sanctioned villains, a dark inversion of their original purpose.

• Ultimate Universe (Earth-1610): In the Ultimate Universe, the “Thunderbolts” were a group of criminals (including Electro, Kraven the Hunter, and others) who were captured by S.H.I.E.L.D. and offered pardons in exchange for serving on a black-ops version of the Ultimates. They were meant to be a disposable squad for high-risk missions. Their story was brief and ended in disaster, showcasing the darker, more cynical nature of the Ultimate Universe's authorities.
• Avengers: Earth's Mightiest Heroes (Animated Series): The team's animated debut in this series was a faithful adaptation of their original comic book origin. The Masters of Evil, led by Baron Zemo, disguise themselves as the Thunderbolts after the Avengers are scattered across the galaxy by Kang the Conqueror. The storyline hits all the key beats, including the final-act reveal and their eventual rebellion against Zemo.
• MC2 (Earth-982): In the future timeline of Spider-Girl, the Thunderbolts still exist, but are a fully legitimate and popular superhero team. The roster includes a mix of new characters and reformed villains, led by the original Thunderbolt, Jolt. This version shows a possible future where the team fully achieves its goal of redemption and public acceptance.
• Contest of Champions (Mobile Game): Several members of the Thunderbolts are playable characters in the game, and the team is often referenced in special events and quests. The game features versions of Punisher 2099 and Red Hulk who were prominent members of different Thunderbolts rosters.
