Ice Shackle Bullet (氷枷弾 Hyōkadan in Japanese) is a devastatingly powerful attack, performed after Free has used Ice Sphere on the ball and chain attached to his left ankle. The dense layer of ice surrounding the ball dramatically enhances the destructive force an opponent suffers. Free, using the leg to which the ball and chain is attached, swings the giant ball of ice at the enemy. He is also capable of picking the ice up and throwing it.
