Kefka, the Dark One. What can be said about him?
Insane is the first thing that comes to mind.
When one reads his magnum opus... one ralphs, then dies.
"A Sorcerer, A Demon, and Emeralds" is an incredibly wrong Sonic the Hedgehog saga in which Sonic the Hedgehog becomes evil, kills Snavely, and overthrows Robotnik (Eggman) permanently. He then proceeds to rape nearly everything on Mobius and severely fuck with the minds of many, many characters.
And there's lemon segments with Robotnik.
Can it get worse?
Just read it.
