My fav kind of villains are the "Joker" kind. Psychopaths with no moral, tragic backstory. they just want to watch the world Burn for what it did to them. He cannot be Talk No Jutsu'd. likes to with Toy he's enemies. but always with interesting dialogs, with a ****ed up twist and a message. Mocking the "normal" people. however he must have Standards, like always has a nice suite or something.

for the evuls trope is what this kinda villain fits into.
while that may be cool and all, it kinda gets boring in the long run, no goals or ideals, just evil.
a good villain is someone who is a. manipulative, b, mysterious, VERY mysterious, whether he is wearing a mask
or simply controlling people and talking to the hero via mind control,
these^ get the crowd pumped for your villain,
the crowd also loves not only a manipulator but a smart one as well, he can't be a villain that is bold at first and becomes over confident to only tell his plans to the whole world and get's a terrible defeat at the end
