The X-1 Ninja Charger was a red roadster driven by Kai, designed for both speed and battle. Its unique feature was the interceptor bike built into the car, which could be launched at will when a faster and more maneuverable vehicle was needed. In addition to the dual missile launchers that folded out from the sides of the car, the Ninja Charger had a rotating engine block with twin-mounted shooters on the underside.
