Ozma. Completely optional boss in FF IX.

And I want to fight him.

Problem is, it's annoying just to get to him. Let me put it like this. You have to find Chocobo's Air Garden, go in it, go to the other island thing, and hit X when you see the ? above your head.

But the fight? Be prepared to reset many times. The attacks I can list off the top of my head are Death, Lv5 Death, Lv4 Holy, Flare, Flare Star, Meteor, Doomsday, Curaga, and Curse.

Meteor is just a giant dick move, usually OHKOing at least a character, if not more. Curse will inflict a shitton of status ailments on you, and hurts like hell. Lv5 Death, Lv4 Holy, and Death are self-explanatory. Flare is okay, just pray it hits your higher M. Defense characters. Flare Star is a dick move. Doomsday is what you would PRAY to see multiple times in a row. If you equipped your party correctly, you'll take no damage, if not just absorb the damage. And it might hurt him or heal him, depending on how the RNG is feeling. Oh, and it's always 9999 damage. And to top it off, Curaga heals him for around 7700~ HP. Considering the son of a bitch has 55,535 HP, that's just a dick move.

And of course I want to fight him at my current level. Well, it's like that quiz I took a long time ago in Lux Pain or whatever the hell it's called. It straight up said that I'm a masochist.
