Crush your Beyblade opponents flat with the Beyblade Metal Masters Gravity Demolition Top Pack. Put together these two Beyblade battling tops, and you'll be ready to take on your friends at high-speed spinning battles. Launch them into battle with the two launchers, and watch them spin to victory. We suggest using theÂ Beyblade Metal Fusion Arena Â as an exciting arena for your battles. Inferno Byxis grips the arena with its Rubber Spike tip, and has a Change Height spin track to adjust your top's height between battles. Battling against it is Gravity Destroyer, who has an Armour Defence track with a solid base to withstand hits and a Wide Defence tip for endurance. Included in the top pack areÂ two secret codes, which you can enter on the Beyblade website to battle online.
