They all suck with the exception of Doflamingo. Anyone claiming the mute King is a good villain is beyond help, anyone claiming the walking PIS in Queen is a good villain is beyond help, anyone claiming the walking meat head punching bag Kaido is a good villain is beyond help, anyone claiming the walking plot device Big Mom is a good villain is beyond help, anyone claiming the walking off screen Jack is a good villain is beyond help. Oda sucks at creating interesting characters beyond their "hype introductions" which is what all these characters are based off just hype and no quality substance.
