I'm trying to make a list of villains brainwashed into at least some sort of reformation by Zatanna. Particularly those retconned in the sense that we saw them improve, but they were later said to have been brainwashed into doing so.

I wasn't reading comics at the time, so please share your opinions on how you felt about any particular villain and their turn to the good/less evil and how it was developed (or not, as is sometimes the case when they suddenly decide a character will turn good/evil) and how you felt about the retcon.
