So, Kefka and Ultimecia are both crazed nihilists with the power to end reality. That actually makes sense. Don't know why you didn't say that at the beginning and had to make that connection using a spade/nutsack in a character's eye, but cool.

EDIT: Wait, I only read the bit about nothing, Kefka and Ultimecia. Clearly, what I'm saying actually doesn't relate at all to what you're saying.
