The main shape of Storm consists of three wing like forms, which are used for considerable Smash Attack. The wheel is a cheaper alternative for that of Quetzalcoatl, and is considered by many to be inferior to the Lightning Metal Wheel.
Storm Pegasis 100RF however is still a good Attack combo, due to a decent level of Smash Attack ability from the Storm Wheel. The slightly jagged end of each of the three wing like forms that Storm consists of are well suited for Smash. Quetzalcoatl, however, is still a far more consistent Attack wheel.
