If it weren't for the Armored Leopard, everyone would have almost forgotten, the pioneer of wheel-type weapons... the Armored Leopard, the father of the Armored series. Master Jiabo designed the Armored Leopard to embody a super concept, so the Armored Leopard's arms are equipped with arm blades, capable of the most extreme close-combat cutting. It can also use conventional titanium golden knives. It also possesses the Cross Wheel, the earliest wheel-type weapon.
The Sky Dance Wheel Fighter is actually an evolved version of the Cross Wheel. However, the Cross Wheel in its inception was axle-driven, and in testing, it accidentally chopped itself up, hence immediately discontinued. The Sky Dance Wheel Fighter now is four-corner driven, with the shoulder and leg accelerators mostly driven by a built-in system, ensuring perfection in combination with the retraction system in the Mecha.
