Sephiroth is my favorite - at least he had a good reason for being crazy.

The worst, Ex-Death, for the reasons mentioned above, and the fact that he's A GIANT TREE. OH NO!

Ex-Death: "My final form is a humongous sycamore! Isn't that horrifying?"

Bartz: "...."

Ex-Death: "Come on, its so twisted! Look at this root, it kinda looks like a dead body!"

Faris: "Arrrrrr....."

Ex-Death: "You won't be so snotty after I branch you to death!"

Reina: "Let's just burn it."

Ex-Death: "NO! I still have so much stuff to suck into my giant black hole for absolutely no reason at all! I never got hugged as a child. . . "
