Some merch spotted by Comic Book Movie has revealed that Erin Kellyman’s character in The Falcon & The Winter Soldier is Karli Morgenthau, a young female incarnation of Captain America villain Flag-Smasher.
Morgenthau was the leader of an anti-nationalist organization known as ULTIMATUM (Underground Liberated Totally Integrated Mobile Army to Unite Mankind) in the source material, and while Karli is sporting a very different costume, it looks like she will take on a similar role in the Disney+ series.
Karli is seemingly in league with Baron Zemo’s plot to end superheroes and as set photos have revealed will likely have some interactions with George St. Pierre’s Batroc The Leaper.
The Falcon & The Winter Soldier begins airing on Disney+ starting March 19th.
