Wing Pegasus 90WF is an Attack-Type Beyblade that was released in Japan in the Beyblade Ultimate DX Set on November 19, 2011, along with Duo Uranus 230WD & L-Drago Guardian S130MB. The popularity of this Beyblade took off after promotional advertisement and the surprising performance levels of its parts. The most distinguishing feature of this Beyblade is the "Wing" 4D Fusion Wheel which is constructed with two components: a Metal Frame and Core. These parts were created as an improved design of the Big Bang Pegasis's Fusion Wheel and, like all 4D Fusion Wheels, can be arranged to up to three configurations, each with their own unique performance properties.
