“You're becoming a bit of a legend. I hear more and more people talk about the freedom fighters who are pushing back. They call you Robin Hood. Every day more people love you.”
The Flag Smashers were a pseudo-terrorist group from the Marvel Cinematic Universe. They believed the world was better during the extermination of half of the universe's population, and hated the state of the world after the other half of the universe's population was brought back to life. They are led by Karli Morgenthau.
Despite being villains, they commit somewhat noble acts like giving medicine to the poor and needy, and shutting down the operations of corrupt corporate executives. They act as enemies of Falcon and Bucky Barnes.
The team dissolved following their defeat and Kari's death in the last episode.
