So I am racking my brains to come up with Black Canary-specific or even Birds of Prey-specific villains, but aside from White Canary, I'm not sure how many others there are. Could you name a few villains who were specifically created to be villains for eit

Hmm. Some became reformed.

There was Savant, Creote, the Twelve Brothers In Silk, Sovereign Brusaw, Harvest, Black Alice, Spy Smasher…there were some more but those are off the top of my brain pan.
