Helmut Zemo, who disassembled the Avengers and was the main reason behind Civil War, will be reprising his role in Falcon and Winter Soldier TV series on Disney+. And Sharon Carter, Neice of Peggy Carter, Agent 13 will be returning too. Both of the characters haven’t appeared in Marvel Cinematic Universe after Captain America : Civil War.
Falcon, Sam Wilson will be using his new Vibranium Shield in the series as he takes the mantle of Captain America. While mostly Harley Keener would be taking the mantle of Iron Man or Pepper will continue her journey as Rescue. Don’t know any thing about that. Actor Antony Mackie is very proud to play Captain America in Marvel Cinematic Universe.
As Marvel introduces Multiverse there are many possibilities that we can get more heroes in Falcon and Winter Soldier, which is still unconfirmed. But Zemo and Sharon are surely going to be in this series.
