Flash (フラッシュ, Furasshu) is a Fusion Wheel released by Takara Tomy as part of the 4D System. It debuted in Japan with the release of the BB-126 Starter Flash Sagittario 230WD on February 19th, 2012. It debuted in western countries with the release of the BB-126-FX Spark FX Starter Pack Flash Sagittario 230WD.
In coordination with the theme of the Sagittario II 4D Clear Wheel, Flash is an assembly of many bow-and-arrow designs.
Flash's Metal Frame resembles the Flame Metal Wheel a lot. It is rather oval, and half of its sides consist in a large and very thick slope. Its underside is mostly empty however, which takes away most of its potential weight.
This piece looks very similar to its Metal Frame, however there is much less relief in it: while the Metal Frame has slopes, Flash's Core is completely flat. This detail means that its underside is entirely filled though, otherwise it could suffer from breakage issues.
- Stamina Mode
In Stamina Mode, the two bow-and-arrow from the Metal Frame are perpendicular to those of the Core. This mode creates a four-winged shape.
- Attack Mode
Once the Metal Frame is rotated by 90°, the Attack Mode is achieved, where the two bow-and-arrow designs of the Core are exactly under the Metal Frame's. The resulting shape of the Flash 4D Metal Wheel is one that is exaggerately elongated. However, most of Flash's weight becomes focused on two distinctive sides, which conveys to it a substantial Flywheel Effect, and since both metal parts are one on top of the other, the 4D Metal Wheel becomes much denser and the weight is shifted from four sides to two sides.
This mode change is possible because of the existence of some small walls on the underside of the Metal Frame.
