Falcon & The Winter Soldier: 9 Fan Theories That Could Come True
9. Zemo Will Be Working For The U.S. Government
Helmut Zemo was one of a handful of villains introduced throughout Phase Three that went a long way towards making up for the MCU's annoying habit of producing lacklustre and disappointing villains.
Though he was ultimately caught by T'Challa, Zemo succeeded in his plan to destroy the Avengers, and bringing him back to face off against Sam and Bucky is a smart move from Marvel Studios.
However, it may not be as straightforward as the villain continuing his revenge arc from Captain America: Civil War. After all, his plan came to fruition as he was able to watch Tony Stark and Steve Rogers tear each other to pieces.
One theory suggests that Zemo will in fact be used as a pawn (of sorts) by the US government. There is no reason to think that Secretary Ross and co. won't still hold the same opinions on superheroes even after the events of Avengers: Endgame, and Zemo would be the perfect way for them to keep the Sokovia Accords relevant and almost control the supply and demand of heroes.
The government won't have forgiven the titular duo for their part in Cap's acts of defiance in Germany, and sending Zemo after them while making Captain America clone "US Agent" the face of the Accords could be their way of taking them down.
