Summary
One ofCaptain America: Brave New World’s many antagonists is Sabra, aMarvelcharacter with a very peculiar comic book origin. After receiving the Captain America shield from Steve Rogers inAvengers: Endgameand accepting the mantle inThe Falcon and the Winter Soldier,Sam Wilson’s MCU storycontinues in Phase 5 withCaptain America: Brave New World. In his first-ever solo movie,the MCU’s new Captain Americawill face a similar challenge to the one that his predecessor faced in all three of his solo movies:protecting the country (and the world) despite the opposing interests of governments and organizations.
Sam Wilson’s second conflict as Captain America comes with bigger threats than Steve Rogers' earliest battles. InCaptain America: Brave New World,Captain America will face at least five enemies, including President Ross a.k.a. Red Hulk, Samuel Sterns a.k.a. the Leader, Giancarlo Esposito’s mystery mercenary villain, a brainwashed Isaiah Bradley, and an untrustworthy government official. While Red Hulk and the Leader are more likely to beCaptain America: Brave New World’s main villains, the movie’s secondary antagonists certainly will pose a considerable threat.
