Key Points:
- Giancarlo Esposito joins the MCU as Sidewinder, a lesser-known but historically significant villain in Captain America: Brave New World.
- The character’s cinematic depiction significantly deviates from his comic book origins, shifting from a teleporting mastermind to a cunning mercenary leader.
- Sidewinder’s future in the MCU could see him evolve into a more comic-accurate version, potentially setting up the Serpent Society as a major antagonist.
Who Is Sidewinder? Marvel Comics’ Criminal Mastermind
Captain America: Brave New World introduces a fresh take on Sidewinder, a villain with deep roots in Marvel Comics. Originally debuting in Marvel Two-In-One #64 in 1980, Sidewinder—real name Seth Voelker—wasn’t always a criminal. Once an economics professor, his life took a drastic turn when he lost his position, pushing him toward Roxxon Oil, a shadowy corporation infamous for its illicit activities.
During his tenure at Roxxon, Voelker underwent an experimental procedure that granted him the ability to teleport via a technologically advanced cloak. With these newfound abilities, he adopted the moniker Sidewinder and eventually founded the Serpent Society, a union-like group of supervillains who specialized in high-risk mercenary work. Under his leadership, the Serpent Society became a formidable force, battling Marvel’s greatest heroes, including Captain America, Iron Man, and The Thing.

How Sidewinder Fits into Captain America Brave New World?
Despite Sidewinder’s deep comic book history, the MCU has taken a different approach to the character. In Brave New World, Giancarlo Esposito’s version of Sidewinder is not a teleporting strategist but a highly intelligent and ruthless mercenary leader. He commands a group of elite operatives who, in a nod to the comics, are referred to as the Serpent Society. Unlike his comic counterpart, Esposito’s Sidewinder has no known superpowers and relies purely on his tactical brilliance and combat skills.
Interestingly, Sidewinder was not part of the original Brave New World script. The character was introduced during reshoots, suggesting that Marvel Studios sees long-term potential for Esposito’s portrayal. His character is hired by Samuel Sterns, aka The Leader, a returning villain from The Incredible Hulk. Initially motivated by financial gain, Sidewinder develops a personal vendetta against Sam Wilson’s Captain America, setting up an ongoing rivalry.

Major Differences Between the Comic and MCU Versions
The biggest deviation in Brave New World is Sidewinder’s lack of supernatural or technological abilities. In the comics, his teleportation cloak gave him a significant advantage, allowing him to outmaneuver enemies and execute high-stakes heists. In contrast, the MCU’s Sidewinder is purely a strategist, relying on his intelligence, influence, and combat expertise. Additionally, his backstory has been altered—there are no mentions of Roxxon, his past as a professor, or his original motivations for becoming a villain.
While the changes may disappoint some fans, they leave room for future developments. Given Marvel’s history of evolving characters over multiple films, Sidewinder could eventually undergo experimental treatments, granting him powers that align more closely with his comic book origins.

What Sidewinder’s Future Means for the MCU?
Captain America: Brave New World may only be the beginning for Sidewinder. The film’s conclusion hints at his return, as he confidently tells Captain America that he will escape prison. This suggests that his character arc is far from over and that future films or Disney+ series could explore his evolution into the teleporting villain seen in the comics.
Moreover, the Serpent Society’s introduction opens doors for a new faction of antagonists in the MCU. With the dissolution of HYDRA and AIM, Marvel could position the Serpent Society as a fresh, ongoing threat—potentially growing into a powerful criminal syndicate akin to DC’s League of Assassins or Marvel’s own The Hand.
Marvel Studios is known for long-term storytelling, and Giancarlo Esposito’s casting alone indicates that Sidewinder won’t be a one-and-done villain. If the MCU follows its usual trajectory, Sidewinder’s next appearance could involve him gaining abilities, recruiting more notorious villains, and cementing his place as a top-tier antagonist.

Sidewinder’s introduction in Captain America: Brave New World marks an exciting expansion of the MCU’s villain roster. While this version of the character is drastically different from his comic book counterpart, there is potential for evolution. With Giancarlo Esposito’s immense talent and Marvel’s penchant for character development, Sidewinder could emerge as a major player in future MCU storylines.
Captain America Brave New World is set to release on July 26, 2024.
