What's a good baddie for an anarchist campaign?

Okay so my players have spent most of their time in Eastern Berlin. After their latest run a big group of anarchists will approach them.

I think I played a bit too much with the "faceless evil" trope so I kinda want to have a proper bad guy on this few runs. The issue being that I don't really know what kind of bad guy would be a good fit. Even the obvious corpo exec I'm having a hard time finding a good motivation.

Do you guys have any idea for a cool bbeg that people would remember? Also even if it doesn't apply to my situation I'd love to hear about your bbeg!
