Hulk Villain Leader's Role in Captain America: Brave New World Explained

by Nicholas May 14,2025

Although Tim Blake Nelson's role as Samuel Sterns/The Leader hasn't been heavily marketed for Captain America: Brave New World, fans have been aware of his return since at least 2022. Nelson originally portrayed this character in 2008's The Incredible Hulk, and his reappearance marks a significant development in the Marvel Cinematic Universe (MCU). The choice to position The Leader as an antagonist in a Captain America film rather than a Hulk sequel is intriguing, and it sets the stage for a unique challenge for Sam Wilson, the new Captain America.

The Leader, or Samuel Sterns, is traditionally recognized as one of Hulk's arch-nemeses. Unlike other Hulk villains who focus on physical strength, Sterns is the antithesis of Bruce Banner. After being exposed to gamma radiation, his intelligence soared to unprecedented levels, making him as intellectually formidable as Hulk is physically powerful. This makes The Leader one of the most dangerous adversaries in the Marvel Universe.

In The Incredible Hulk, Tim Blake Nelson's portrayal of a pre-transformation Samuel Sterns sets the stage for future conflicts. Sterns, a cellular biologist, aids Banner in his quest to cure his Hulk condition. However, his interest in Banner's blood stems from a belief that it could unlock humanity's potential and eradicate disease. This leads to his coerced involvement in transforming Emil Blonsky into the Abomination. The film concludes with Sterns on the brink of becoming The Leader after his exposure to Banner's irradiated blood.

Expect Nelson's character to look a bit different when he returns in Captain America: Brave New World.

The Return of the Leader in the Marvel Cinematic Universe

The tease of Sterns transforming into The Leader in The Incredible Hulk hinted at a sequel that never materialized due to Universal Pictures retaining some film rights. This has led to Hulk's narrative unfolding through the Avengers films and Thor: Ragnarok. Meanwhile, Bruce Banner's recent adventures in She-Hulk: Attorney at Law have seen him leave Earth and return with a son, Skaar, further expanding his storyline.

Rumors suggested The Leader might appear in She-Hulk, but it's in Captain America: Brave New World that we finally see him. The Leader's absence from direct Hulk confrontations and his presence in a Captain America film is a strategic move by Marvel, reflecting the interconnected nature of the MCU.

Why the Leader Is One of the Villains in Captain America 4

The Leader's appearance in a Captain America film might seem unusual, but it's a calculated choice. While he may not have a direct vendetta against Bruce Banner, his transformation and subsequent betrayal by General Ross and Emil Blonsky provide ample motivation for revenge. With Harrison Ford stepping into the role of President Ross, The Leader's plan might involve discrediting America and targeting the new Captain America, Sam Wilson.

Director Julius Onah emphasizes that The Leader's danger lies in his unexpectedness as an adversary for Sam Wilson. Onah shared with IGN at D23 in 2022, "Actions have consequences, and that's what's so great about what the MCU has been able to build... Tim Blake Nelson coming back as The Leader is such an exciting thing to explore because his story now is going to challenge Sam Wilson, our new Captain America, in a way that he never expected."

This film will be Sam's first major test of leadership, requiring him to rally the Avengers against a threat unlike any they've faced before. Onah noted, "The world has changed a lot too. And the role of a hero has changed... The decisions he's going to have to make, and the situations he's going to be confronted with, are radically different from what Steve Rogers had to deal with."

PlaySam Wilson has tussled with some of the strongest villains in the MCU and lived to tell the tale. But he's never faced someone as intelligent as The Leader. Is he up to the challenge? We'd like to say yes, but it's telling that Captain America 4 sets the stage not for the next Avengers movie, but for the Thunderbolts movie. The Leader may have a hand in destroying the symbol that is Captain America and ushering in a newer, darker era for the MCU.
