"OK, I had to add other to this poll. Because really, none of those villains hold a candle to the likes of the FFT villains.
So in this case, I'd say Dycedarg or (if you want to count him) Delita. They raise manipulation to an art form."

I don't put the FFT villain in the poll, exactly because of this. They will win for sure. Puting the FFT villain in a poll like this, is the same thing as puting Sephiroth in a poll that said "Who is the more badass villain?".
