impossible to kill would be my choice:P

The center of the abyss. Just a big ball of floating light.

Physical attacks causes Petrification, and if not immune, instantly shatters them. Counters any damage every single time with non-reflectable Life Force that always restores 9999HP. Heartless Angel brings everyone down to 1HP. Death Spawn kills 3 characters instantly (ignores any Deathproof status). So you have to have all 4 characters alive ALL the time. Grand Cross causes every single status in the game excluding KO and Petrify. Omega Max depletes all MP from entire party.

10000HP. So basically, all 9999 attacks bring him down to 1HP, but he immediately counter-heals himself up to 10000HP. Immune to every bad status as well.

He has 300MP and life force costs 1MP. So you have to attack him 300 times before he can't heal himself. Immune to all MP depletions. BTW, you can't hit for more than 9999 in one turn.

Anyone wanna face this guy?

EDIT: Oh, and he has a special attack. Yes, after all that good stuff he has a special attack. Endgame. If given a turn after his MP has been depleted, he immediately uses Endgame. Physical attack that hits every character for 9999. Never misses. Damage can not be reduced.

Id fight like this
Begining of fight it starts to rain both look up and drops pour from the sky both are using katana blades both heavily skilled,you hear a lighting bolt and they clash,every time they is a lighting bolt i dissapear and reapper,if i get weak and ill do is go to some near by mountains both on top of a Mountain peak(One mountain peak per player)This is the last clash they clash again and a bunch of quick time event occur while there both fighting you hear a bunch of lighting bolts theyre both blocking and evading each others moves while the rain is being sliced...
I get weak as in One more hit and Im dead

I would take 3 hits to kill, I would not use some of my moves until I was on my final hitpoint.

Their wouldn't be a final boss fight cause I'd kill the bastard while he's still weak in the beginning of the game.

i would be a giant rubber monster, reflects back basic magic attacks at all opponents. immune to poison, sleep, and that crap. I'd have 7331HP, with insane defense. Able to block all 9999 attacks.

That battle would take place on a cruise shit, with random women running around topless. Attacks send these women at the screen.

Heroes wouldnt be lame, emo, tards.

Story would revolve around some book, and make no sense. The final fight is a horrid plot twist based around a pervert's dream.

Music, would be some heavy rock song. Probably Beginning of the End by Spineshank.

Hopefully people have seen Princess Mononoke. I would be the Spirit Walker from that movie. That guy kicks ass. Too bad he's a pushover during his transformation stage.
