Kai's X-1 Charger was a high-tech car that he obtained during the Golden Master crisis. He drove it for most of the period, and its powerful functions made Kai the main eyes on the ground of Team Ninjago. It was capable of converting into a powerful jet fighter, which he used to patrol the skies during the latter half of the crisis. He kept the car after the Nindroids were defeated, occasionally using it for high-speed road chases.
