Uh I don't know about that, Sora and Waluigi already have voices but thank you for your intrest! As for the spin attack yea it does a lot of damagae. But there is a way to tell what attack he is gonna do. If he runs really fast to you he is gonna do the stomp attack. If he starts to run at you he is gonna do the spin attack. Now this does change if you are close to him he won't do that so yea I guess there is no windup really but eh. There is also the golf attack but that has good windup. Fight him like roxas, thats what I based him on!
