yuna's final aeon - her father (lord braska?)

overdrive - a random overdrive of the other aeons, but heals as much HP/MP that the attack hits for.

abilities - double cast, break damage limit, counter attack

spells - ultima, meteor, holy, flare, curaga

stats - 150 str and mag, 255 vit and spirit, 48 luck

I think it would be cool to see her father run around and cast mega flare in place of bahamut.
