I guess the hardest guy is in the arena after you capture 10 of everything. I am close to that so I am looking forward to fighting it. Just pis ses me off that they put guys in the arena that are harder than the end boss.

Hehe, you haven't fought Penance yet have you?

If you get FFX International version, you have the opportunity to defeat the Dark Aeons, and if you do that (which would mean that you are one seriously hardcore bastard!) then you would face Penance......

Oh, the pain.....
