Okay, I've tried at least a fair few times with this guy. I can run pretty well until he gets to around 12k-14k HP and then he uses Proto Omega which pretty much screws me over, because after that there's no way to revive anyone as he boosts so much and casts Quick on himself.

I am level 40 for every character, so far I've tried using Ziggy, KOS-MOS, Jr. and Jin, and I have started learning level 3 skills. So far I've been dealing pretty reasonable numbers with KOS-MOS, Jr. and Jin. I managed to get him down to 15kHP on his second form with combos, but after that, he just seems to quick and I am unable to really do anything apart from keeping myself healed.

I'm not really into the whole leveling up in this game, especially when normal battles take forever to complete, and they aren't random.

Is there any help that anyone can give me? I just feel like loading up someone elses save file and using that, but I just want to beat it on my own. >.<;
