I am very suprised anybody hasn't asked this question yet. Which one off all Final Fantasy games is the hardest boss? This doesn't need to be, one in the end. I know by example that the Weapons in FFVII are quiet hard, or what about Ozma in FFIX. And there are more like those irritating creatures, who are there to make your live in FF a hell. I don't know all the bosses, but I defintely go for Ozma. Oh, boy. He is one heck of a nasty creature, allthough Omega Weapon in FFVIII isn't easy at all. Oh, hell, what about both. They are both hard bosses.
