I wonder how a fusion could work... say, you and a friend have to be SSJ with Chibi Trunks and Goten and then you power up, select fusion from the menu, do the dance, fuse, and then choas erupts as you try and move together followed by SSJ3 Goku shooting a **** off Kamehameha at you and destroying you both... man i want that in the game O_O hehe
