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.
Flash's Metal Frame resembles the original Flame Fusion Wheel. It is in an oval shape. It's underside is hollow, and due to this, weight is lost.
The core resembles the Metal Frame, but looking slightly more like a circle. It retains it's bows and small spikes though.
Like other 4D Metal Wheel, Flash is able to change modes. 'Attack Mode', where the Wheel takes an oval shape reminiscent of its original form, Saggittario (Pre-HWS). By simply turning the Metal Frame sideways, Flash enters 'Stamina Mode', where Flash takes a layered resemblance, looking like it's previous form, Flame Saggittario. Because of the ovular Frame and Core being stacked in opposite directions, this mode looks more like a circle compared to the oval-like shape of Attack Mode.
Stamina Mode doesn't hold too much Stamina to stay up long because the Wheel has too many points of weight distribution,having about four or five,and can be easily knocked out of the Stadium because of its light weight,but this means that Sagittario becomes faster the more it moves.And since Attack Mode only has two points of weight distribution, not only does it hold more Stamina than Stamina Mode, but is overall much better. However, since Attack Mode is an oval-like shape it catches the wind and reducing rotation speed,followed that when the Frame and the Core are combined into one,it becomes much more heavier than Stamina Mode,making it vulnerable to lose Stamina if the Wheel is in contact with the stadium floor.It has found great use in Attack customizations with its minimum recoil. It also does a great job at pushing opposing beys; staggering them into a corner and losing their balance. It also has less chances of being knocked out compared to other top-tier Attack Wheels like Variares, Beat and Fang.
