Beyblade: Metal Fusion, known in Japan as Metal Fight Beyblade Metaru Faito Beibureedo), its Japanese name, is a Japanese manga production by Takafumi Adachi. It is also an anime production based on the original. It is currently being serialized by the monthly CoroCoro Comic (Shogakukan)(4-piece top), while in the anime they started with the Hybrid Wheel System (5-piece top)(multi-part construction)(except the Performance Tip). Energy Ring - The Energy Ring is where the launcher hooks stay when connected and determines the direction the bey will spin. In three cases in this System, the Energy Ring is not used (Variares D:D, L-Drago Destructor F:S and L-Drago Guardian GB145MB)4D Wheel - Similar to the Fusion Wheel, a 4D Wheel is the part that helps attack other Beyblades. The main difference between the two types is that the 4D Wheel is composed of three or two parts, rather than one: Metal Frame, PC Frame and the Core. By using these three components in different positions, the Bey's contact points can change.4D Bottom - The 4D Bottom is a combination of a Spin Track and Performance Tip, put together in one package. Usually, a 4D Bottom will be at a 14.5mm height and will have some sort of gimmick:Final Drive (F:D) will switch from a Semi-Flat tip to a Rubber Flat when its Stamina is low.Final Survive (F:S) will switch from a Hole Flat to a Sharp tip when its Stamina is low.Delta Drive (D:D) can be switched between three different tips before a battle; Flat, Sharp and Wide Ball.Bearing Drive (B:D) contains ball-bearings, which helps maintain a Bey's stamina for a longer period of time.X Drive (X:D) can be switched between three tips before battle, and will switch between others during the battle.
