Tim Blake Nelson's return as Samuel Sterns/The Leader in Captain America: Brave New World is a significant MCU development. While initially introduced in 2008's The Incredible Hulk, his transformation into The Leader was left unresolved. This sequel unexpectedly positions him as a Captain America antagonist, rather than a Hulk-centric villain.
The Leader, Hulk's primary nemesis, possesses intellect rivaling the Hulk's strength. His gamma radiation-enhanced intelligence makes him exceptionally dangerous. Initially an ally to Bruce Banner in The Incredible Hulk, Sterns' ambition to harness the potential of gamma-irradiated blood ultimately led to his own transformation.
The absence of a solo Hulk sequel, due to Universal's film rights, explains the Leader's delayed reappearance. His inclusion in Captain America 4 is a strategic move, capitalizing on unresolved plot points. While some speculated on his involvement in She-Hulk: Attorney at Law, his role in Brave New World remains a surprise.
The Leader's motivations remain unclear. While he might harbor resentment towards those responsible for his transformation (Ross and Blonsky), his targeting of Captain America suggests a broader agenda. His potential desire for revenge against President Ross (Harrison Ford) could involve discrediting the American government on a global scale, thus making Captain America a key target.
Director Julius Onah highlights the Leader's unexpected nature as a key element of the film's narrative. This unexpected threat will test Sam Wilson's leadership abilities and force him to unite a new generation of Avengers against a formidable intellectual adversary. The film's conclusion may not lead directly to the next Avengers movie but could set the stage for the Thunderbolts film, potentially signifying a darker era for the MCU.
The film also presents a poll question: Will the Hulk defeat Red Hulk in Captain America: Brave New World? The options are Yes!, No!, It'll end as a draw!, and It depends (tell us why in the comments!).
