Yuna is so strong, it's almost sad. All of here Aeons (Accept the Magus sisters) since she does 99999 points of damage along with her aeons. Her Aeons normal attacks do 99999 so their overdrives are useless.

I have most of her stats maxed out and shes completed the sphere grid. I belive shes over 60,000 HP and either 2000 MP or just under that.
