Using his Explosion Release as a method of defense, Magyaku uses Shape Transformation to form a sphere of protection. Being a man of sheer power, when anything physically touches the outside of the sphere a explosion occurs on that spot . So if one were to physically punch it they'd almost certainly lose their hands/arm from the damage. Once Magyaku, cleared a large company of assailants with this technique, and he didn't even have to lift a finger. He has shown to even ram the sphere into the grown or an objrct to create an explosion.
