A low-down from the villians of FF6 to 10.
May be Spoilers
Spoiler:

Kefka-Was excellent. Completely original and loved mass destruction (who doesn't?)

Sephiroth-Was brilliant. Wanted to become a god and rule the world with mummy(which was a bit sad).

Ultimecia-WTF? Where'd she pop out of with the worst dream ever, just her and only her. Where's the evil? You can't think of how evil she is if your frozen for all eternity.

Kuja-Very evil but too efeminite. Plus, he only really went crazy when he realised he coudn't live for ever.

Yu Yevon-Worst enemy ever, too easy, was just a black spider, wait a min......

Seymour-Here we go, much better then Yu Yevon. I think he should of gone out with Kuja, Kuja would wear a dress and Seymour would talk like a girl, plus he had a beer belly - that's not evil!
