The Flag Smashers are a pseudo-terrorist group from the Marvel Cinematic Universe. They believe the world was better during the extermination of half of the universe's population, and hate 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.
