Final Fantasy X/Aeons

Anima is Seymours aeon but you can obtain him but i dont know how to off of the top of my head.

anyway his special attack is "pain". the first time you see anima is after the blitz ball game that you get to play at luca when all the fiends start attacking. thats also the first time you see "pain".

his overdrive is "oblivian". oblivian is when anima takes you under ground and his lower half brakes out of its chains. it delivers hit after hit that sounds kinda like a rap beat. if you have ever seen the first lord of the rings animas lower half looks like the the ring hunters {the guys with the black hoods} when frodo puts on the ring. it doesnt look exactly like them but the look somwhat the same.
