Kefka vs. Sephiroth

There's no way Kefka wouldn't win. Absolutely none. If Final Fantasy VI wasn't limited to the fact that, well, it's a game and the player has to be able to win in some form, there's no way the Returners would have been able to defeat him either. He became the god of all magic and was powerful beyond all comprehension. He even created his own spells: Light of Judgment and Forsaken. Of course, given how nihilistic Kefka was, he could have let them win. It seems likely he realized his own mortality (though given his power, perhaps he could have lived forever disproving this theory?) or accomplished all the destruction he felt necessary and was ready for his life to end. "Life, dreams, hope... where do they come from? And where are they headed?" In this case he could have been speaking of himself. His laugh heard during the final battle would have been because of the Returners proving him right. He did turn out to be right, however: everything exists to be destroyed. Everything ends in ruin and death. He wanted to leave a monument to non-existence, and even after he was defeated and the world began to recover, signs of Kefka's reign and destruction of the world would have remained. He perhaps realized (in his own twisted mind) that because life has no meaning, neither does his.

Plus Kefka gets extra points for starting out as a completely normal human with no extraordinary powers (until his Magitek infusion which granted him some magic and broke his mind), and gradually becoming more and more powerful simply through the use of his own cunning and deviousness. And, as everyone knows, Kefka is a rare exception in that he actually succeeded in his goal (arguably even after he was finally defeated) and held a destructive and terrifying reign over the world for an extended period of time before the Returners could regroup enough to overcome him, whereas Sephiroth did not. Also not sure why some people are saying Kefka wasn't physically powerful. Look at his final form sprite! That guy is covered in muscles! He doesn't even need a weapon, he just punches you in the face. Not sure what looking "scary" has to do with anything either, or why no one would be afraid of Kefka. He had a reputation for being incredibly dangerous and he was (one of) the most feared people in the Empire.

Sephiroth wanted his mommy and summoned a big rock.

Hm... who is the winner here?

(Of course I have to point out how ridiculous and overdone this pairing is here. It's not like it's never been done or these arguments haven't been made before.)
