Not. Even. Possible.
This dude must have epic level magic. Or some kind of superfantastic Wisdom Form drive that I have not been allowed to use.
I DON'T CARE WHAT ANYONE SAYS. I am a damn good gamer. I just like to take my time during boss fights. If it takes me 20+ minutes to fight the simplest boss, so fucking be it. I like the special moves and the fact that this may be the last time I'm fighting badass dudes. I DO NOT LIKE timed kills. I DO NOT WANT to have to kill X amount of baddies in X amount of time in a boss fight.
And for this reason, Demyx is my KH kryptonite. Took me like 15 tries on proud and he still beat me hard on standard (though only once, then I murdered him) and it makes me feel so... inadequate... and inexperienced. I DIDN'T GET THIS FAR IN THE GAME ON LUCK, YOU KNOW.
Me in this fight is like... thunder, thunder, wild dance, wild dance, wild dance... and on the off chance that I've gotten enough of the little liquid bastards to satisfy this game's lust for blood and tears, I proceed to maul Demyx with drive after limit after drive of my heaviest shit... only to get stuck in an even harder liquid bastard genocide half an energy bar from finishing him. EVERY. TIME.
DAMN YOU. DAMN YOU DEMYX. DAMN YOU DISNEY. DAMN YOU SQUARE.
