Power Broker

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

Part 2: Origin and Evolution

Publication History and Creation

The concept of the Power Broker was introduced to the Marvel Universe by writer Mark Gruenwald and artist Paul Neary. The original Power Broker, Curtiss Jackson, made his first appearance in Thing #28 in October 1985. Gruenwald, known for his meticulous world-building and logical approach to the mechanics of a superhero universe, conceived of the Power Broker as a practical answer to a fundamental question: in a world full of super-beings, where would an ordinary person go to acquire powers if they had the money? This creation was deeply rooted in the cultural zeitgeist of the 1980s. The era's obsession with physical fitness, body-building, and the rise of professional wrestling provided the perfect backdrop. Gruenwald created the Unlimited Class Wrestling Federation (UCWF), a wrestling league for super-strong individuals, as the primary public face and recruitment tool for the Power Broker's far more sinister operation. This allowed him to explore themes of ambition, exploitation, and the physical and psychological costs of “unearned” power. The Power Broker was not a cosmic threat or a maniacal despot, but a grounded, predatory capitalist, making him a uniquely chilling and relevant antagonist for the time.

In-Universe Origin Story

The origin of the Power Broker differs drastically between the primary comic continuity and its cinematic adaptation, reflecting the different narrative needs of each medium.

Earth-616 (Prime Comic Universe)

The story of the Power Broker in the Earth-616 universe is the story of Curtiss Jackson, a brilliant but utterly amoral businessman. Jackson saw the proliferation of superhumans not as a marvel, but as a market opportunity. He founded Power Broker, Inc. with a simple, revolutionary business model: to sell superhuman strength to anyone who could afford the price. To achieve this, he partnered with the gifted but disgraced geneticist, Dr. Karl Malus. Malus developed a highly dangerous and experimental augmentation process that used a combination of chemical treatments and focused radiation to grant individuals superhuman strength and durability, typically in the Class 10 to Class 50 strength range. The procedure was notoriously risky, with a roughly 50% failure rate; “failures” often resulted in grotesque mutations or death. To lure in a steady stream of willing test subjects and clients, Jackson established the Unlimited Class Wrestling Federation (UCWF). This wrestling league provided the perfect cover, appealing to ambitious athletes who craved the strength to compete. Potential clients, like Dennis Dunphy and Sharon Ventura, would sign exploitative contracts, agreeing to give Power Broker, Inc. 70% of their earnings in exchange for superhuman abilities. The true horror of Jackson's operation lay in its method of control. The augmentation process was deliberately unstable, requiring subjects to take a regular dose of a special stabilizing drug. Jackson, of course, was the sole supplier of this drug. This created a permanent, debilitating dependency, effectively enslaving his clients. If a client rebelled or tried to escape their contract, Jackson would withhold the drug, causing painful and often lethal cellular breakdown. For those who proved too troublesome, he had Dr. Malus perform a “de-augmentation” process, which was even more excruciating and dangerous than the initial treatment. It was through this process that two of his most famous clients, John Walker and Lemar Hoskins, gained their powers. Seeking to become patriotic heroes, they subjected themselves to the treatment, which ultimately set them on the path to becoming the new Captain America and Bucky, respectively. This brought the Power Broker into direct conflict with Steve Rogers, who was appalled by the organization's predatory practices. Curtiss Jackson's reign eventually ended when he was targeted and seemingly killed by the Scourge of the Underworld, a vigilante dedicated to assassinating super-criminals. Though Jackson later returned, having faked his death, his organization was shattered. In recent years, the “Power Broker” name has been co-opted by a new, mysterious individual who runs a high-tech, decentralized operation via a mobile app called Hench X, allowing users to “shop” for temporary powers, continuing the legacy of commodifying superpowers for a new generation.

Marvel Cinematic Universe (MCU)

The MCU's interpretation of the Power Broker, revealed in the Disney+ series The Falcon and The Winter Soldier, is a dramatic and shocking departure from the comics. In this continuity, the Power Broker is not Curtiss Jackson, but Sharon Carter, the great-niece of Peggy Carter and a former S.H.I.E.L.D. and CIA agent. Her dark turn began after the events of Captain America: Civil War. For aiding the fugitive Steve Rogers, Sam Wilson, and Bucky Barnes, Sharon was branded a traitor by the U.S. government and forced to go on the run. Unlike the other members of Team Cap, she was not an Avenger and received no support or pardon. Abandoned and disavowed by the country she had sworn to protect, she fled to the lawless island nation of madripoor. Using her formidable skills in espionage, combat, and intelligence gathering, Sharon didn't just survive in Madripoor's criminal underworld; she conquered it. Over the years following the “Blip,” she built a vast network, dealing in stolen art, advanced technology, and state secrets. She shed her idealistic identity and forged a new one built on power, influence, and cynicism, ultimately adopting the moniker of the “Power Broker,” the unseen and feared ruler of Madripoor's criminal element. Her primary business was not strength augmentation but something far more valuable: the Super-Soldier Serum. She located and funded the work of Dr. Wilfred Nagel, a former Hydra scientist who had successfully recreated the serum from the blood of Isaiah Bradley. Sharon's goal was to mass-produce the serum and sell it to the highest bidder, creating a private army of super-soldiers loyal only to her. Her plans were thrown into disarray when her lead scientist, Nagel, was killed and all twenty vials of the completed serum were stolen by Karli Morgenthau and the Flag Smashers, a group of anarchists she had initially sponsored. This betrayal set the stage for the events of the series, as Sharon manipulated Sam Wilson and Bucky Barnes, who were hunting the Flag Smashers, to unwittingly help her reclaim her “property” and eliminate her rogue assets. She played the part of a bitter but helpful exile, all while orchestrating events from the shadows. In the series finale, she personally kills Karli Morgenthau and leverages her assistance to Sam and Bucky to receive a full pardon from the U.S. government, callously using her reclaimed status to immediately begin selling government secrets and weapons to her network.

Part 5: Iconic Events & Storylines

The New Captain America (Captain America #328-350)

This seminal storyline by Mark Gruenwald is the Power Broker's most significant appearance. When Steve Rogers resigns as Captain America rather than become a government agent, the U.S. government seeks a replacement. They find him in John Walker, the “Super-Patriot,” who gained his powers from Power Broker, Inc. The story arc delves deep into the consequences of this decision, as Walker's more brutal methods tarnish the shield's legacy. Meanwhile, a disenfranchised Steve Rogers, operating as “The Captain,” investigates the Power Broker, tracing the source of Walker's powers back to the corrupt organization. This event cemented the Power Broker as a crucial element in Captain America's lore and was a direct inspiration for major plot points in The Falcon and The Winter Soldier.

The Thing & The UCWF (Thing #28-36)

This storyline served as the formal introduction of both the Power Broker and the UCWF. When The Thing temporarily loses his powers, he joins the UCWF as a regular human wrestler. He soon discovers the dark secret behind the league: that many of its stars are receiving dangerous augmentations from Power Broker, Inc. The Thing's investigation exposes the full depravity of the operation, including the addictive drugs and the fatal consequences for those who defy Jackson. It's a gritty, street-level story that establishes the Power Broker as a serious threat.

Scourge of the Underworld Saga (Various)

While not a single event, this long-running subplot had a major impact on the Power Broker. A mysterious vigilante known as the Scourge of the Underworld began systematically murdering supervillains, shouting his catchphrase, “Justice is served!” Curtiss Jackson became one of his victims (or so it seemed) in Captain America #319. This act effectively decapitated Power Broker, Inc., sending the organization into chaos and allowing for other players to try and fill the void. Though Jackson was later revealed to have survived, the Scourge's attack marked the beginning of the end for his original empire.

The Falcon and The Winter Soldier (MCU)

This is the definitive storyline for the MCU's version of the character. The entire series revolves around the consequences of the Power Broker's actions. Having funded the recreation of the Super-Soldier Serum only to have it stolen by Karli Morgenthau, Sharon Carter spends the season orchestrating events from her throne in Madripoor. She masterfully manipulates Sam, Bucky, and Zemo to hunt down Karli and the serum for her. The series culminates in the shocking reveal of her identity and her successful re-instatement into the U.S. intelligence community, placing one of the world's most powerful criminals in a position of immense authority.

Part 6: Variants and Alternative Versions

While the Curtiss Jackson and Sharon Carter versions are the most prominent, the concept of the Power Broker has appeared in other forms.

Notes and Trivia

1) 2) 3) 4) 5) 6)

1)
The creation of the Power Broker by Mark Gruenwald in the mid-1980s directly mirrored the explosion of popularity in professional wrestling, particularly the WWF (now WWE), and the era's focus on bodybuilding and physical enhancement. The UCWF is a clear parody of this phenomenon.
2)
In the comics, the Power Broker's augmentation process is pseudo-scientifically described as a catalyst for unlocking the “latent potential” within human DNA via a combination of chemical and radiation treatments. This vague explanation allows for a wide variety of outcomes and side effects.
3)
The decision to make Sharon Carter the MCU's Power Broker was one of the most controversial creative choices in The Falcon and The Winter Soldier. It represented a fundamental heel turn for a character who had, until that point, been a steadfastly heroic ally to Captain America. Creators cited the desire to show the cynical consequences of her being abandoned by her country after Civil War.
4)
Key Comic Book Issues: Thing #28 (First Appearance of Curtiss Jackson), Captain America #328 (John Walker receives powers from Power Broker), Captain America #375-378 (The “Streets of Poison” arc, where Captain America deals with the fallout from the Power Broker's drug network).
5)
The name “Madripoor” and its division into “Hightown” and “Lowtown” is a direct homage to the island's depiction in the X-Men comics, where it frequently served as a base of operations for wolverine. The MCU's decision to make it the Power Broker's seat of power integrates this iconic location more broadly into the universe.
6)
The modern “Hench X” app version of the Power Broker serves as a commentary on the “gig economy,” applying its principles of temporary, app-based contract work to the world of super-crime.
