Yeh, kefka was just crazy. A friend of mine summed it up when he said "If you ever gave the joker god like powers, you'd end up with kefka". Which is why he is far superior to sephiroth. Yes, the joker does have a background story, and its rather "meh". The real appeal of both characters character is his charisma and psychotic genious. Out of all the villains in the batman and final fantasy universe, they are the worst not because they're the most powerful, not because they have the most high tech gear, not because of the cool origin, but because they are the smartest, and most evil sunuvabitch's you ever met.

Standout moments with kefka would be the utter genocide of the esper race, the reather cold blooded and pointless murder of leo, the poisoning of the doma castle river, and my personnal favorite: Kefka's fight with the emperor. Complete with kefka pretending he was scared with each attack.

oooh, almost got me that time

Whew, that was close. I Thought I was dead for sure

A little to the left, your almost there!

Muahahahaha

Yah, kefka was just the coolest. Sephiroth might have been cool if he had half kefka's fashion sense, (Evil clown getup vs V-neck leather = Evil clown wins hands down) and a portion of kefka's charisma and competence
