10 Hardest Bosses In Final Fantasy History

Final Fantasy IX is packed with incredibly hard optional bosses, but the one that stands above them all is Ozma. You can only face Ozma after going through the entire Chocobo storyline, which requires hours upon hours of dedication along the entire length of the game. After getting to the final area and nabbing all the awesome goodies the chocobo gardens grant you, you are rewarded with a fight against the hardest boss in the game. 

There are many, many reasons this boss is so infamous, but chief among them is the fact that you have to complete ANOTHER sidequest just to hit the damn thing at all. If you do not complete the friendly monster sidequest, then Ozma is immune to all physical attacks and absorbs all shadow-element attacks. His fight also changed the ATB system, where his attacks take priority over your party, and his ATB bar will fill up automatically whenever you select a command. The only way around this is to select commands when he is in the middle of his attack animations. 

And even if you jump through those hoops, there's still the matter of his attacks being the most devastating in the entire game, and having multiple attacks per round. This fight will demand everything of you. But if you got to him at all, you're probably ready.
