Sephiroth has that feeling of pure evilness....He is just so cold, the way he talks...everything. It just makes him a great villian...I would have to say he is the best...an opinion obviously, I don't need facts to support an opinion, especially if other people don't feel the same way...

Kefka is awesome too...but in a much different way. He protrayed more of insanity. He was evil too, just not concentrated like Sephiroth. He moved statues that controled the balance of the world, without even thinking!! And used poison on the water supply not caring about families! He seemed to have a few screws loose. Evil and a good villian yes, but it seems that someone more in control of what they were doing could do better...

Kuja...I thought he was a woman the whole game!! I kept confusing him with Beatrix!! LOL...He actually had some control of his actions, but saying he was a good villian is like saying liza is too..you need looks and personality..he definitely had the personality...and the power..but I would take a guy in a trench coat with a long sword over a guy wearing a thong anyday...
