Metal Balls are balls made of metal that can go into the base of most Draciel Beyblades. All of the Draciels except for Draciel MS has a set of Metal Balls located in the Beyblade Base. The bases that can have the metal balls added or removed are that of Draciel Metal Ball Defenser, Draciel S, and Draciel F while the bases of Draciel V, Draciel V2, and Draciel G have fixed metal balls, balls that can't be removed, inside of the base. It should also be noted that Draciel F has a free spinning metal ball in its base.
Even though it is not noticeable, Draciel G has a set metal balls, however, they are not as big as the other two versions.
