I hate seymour... his voice is gay, his face and body is fucked up. And uh... i donno if u count this as a villain but Beatrix in FF9? She is a cool villain. Sephiroth... got to be my favourite, Kuja was kinda of girl looking person but he wasnt bad and the 2 optional bosses in FF8 called Ultima Weapon and Omega Weapon was cool.
