I personally don't really like villains with a tragic backstory since that's sort of a given at this point. But I do hate-love most evil villain characters, sort of like regina george from mean girls. Other than that, I'm a big fan of the quiet character. Especially if there's a big twist where they turn out to be the antagonist.
I wish there was an option for a "blunt character". I like characters that are straightforward and can be honest, since you don't see that a lot in real life.
