One of the most disturbing characters made for the fighting game engine Mugen
. Created by Ex Inferus (who, from what I heard, used stolen coding) this char is an edit of Kula Diamond (a KOF character). What makes her so disturbing is that basically, Kula has come back from the dead as Isabeau (after either being crucified or impaled on a stick.) She's been given hellified powers and she sometimes summons demons to attack you. When beaten for the second round, she explodes into a mutilated mess. Just a note for those who are easily disturbed or sickened by the sight of dead bodies and hell-like stuff, DO NOT DOWNLOAD THIS CHARACTER IF YOU FIND HER! She will give you nightmares!
Other than that, she's a pretty good character to own: if you like characters that have very cheesy moves and can hardly be beaten.
Isabeau has owned every character in my roster.
