I think she is an incredibly annoying villain with very weak and petty motives.

A villain more boring than Malekith

I thought she was annoying, petty, angsty, boring and terribly wtitten

Look, guys, I don't think she deserves to be the worst villain rated. What does anyone else think of Morgenthau?

I thought Flag-Smasher was fine villain but the show kept trying to say that she wasn't a villain when she obviously was. I think they should have written her more like Killmonger a man who starts off having a noble goal but whose actions turn him into a monster. Both Erik and Karli have very similar plots which is get revenge on the people who wronged them by making them go through the same thing; Killmonger wanted to Black people and to use vibranium weapons to threaten and oppress White people and Flag-Smasher wanted those who survived the Blip to have a more secure lifestyle and social status than those who died. The difference is that Erik knows full well that he is a terrorist revolutionary but believes that his ends justify his means whereas Karli and even Captain America himself refuses to accept that while she might have a legit grievance with the GRC, blowing up innocent people for the sake of a message in the definition of terrorist, TLDR if they wanted the villain to be morally grey they should have let U.S. Agent be the main threat

At the beginning she had some interesting motives but in the end she basically just became a boring, poorly-written Killmonger knockoff.

@Ra3099 Do you still think Karli Morgenthau is pretty interesting character?

@Sam Katawazi I think she was a character with some interesting potential but Marvel dropped the ball in the execution. Is she the worst villain in the MCU? No, that title will forever be held by Malekith the Accursed but she could have been better

@Ra3099 Do you think if she'll ever return, they'll give her more depth?

@Sam Katawazi I doubt it, I think the closest we'll get is her memory looming over both Sam Wilson and Sharon Carter in Captain America 4 as I am pretty convinced that Sharon is going to be the main villain of the film and her murder of Karli is a secret that could drive a strong wedged between them when Sam finds out
