While it’s been known for a while that Baron Helmut Zemo will be returning to The Falcon and the Winter Soldier on Disney+ as the series’ primary villain, it’s also been made clear that a secondary antagonist will be making their debut - John Walker, alternatively known as the Super-Patriot, USAgent, and Captain America.
And who is John Walker? Set to be played by Wyatt Russell - son of Kurt Russell and Goldie Hawn - in the upcoming series, he’s the pseudo-superhero chosen by the US government to replace Steve Rogers as Marvel Comics’ Captain America during one of the latter’s many impromptu retirements. This should bring him into direct conflict with Sam Wilson, the man Rogers chose as his own replacement in the Marvel Cinematic Universe.
Walker is also notable for his hardcore right-wing political alignment, which makes him diametrically opposed to many of the ideals that have long defined the mantle of Captain America - and the beliefs of Steve Rogers himself. This has led to countless battles - and a few begrudging team-ups - between the two, but with Rogers now absent from the MCU, it will be up to The Falcon and the Winter Soldier to face off with him instead.
