Moving beyond the Spychangers, the signature trio of the Robots in Disguise animated series and toyline were three car brothers. Prowl is the first of the three to get a daily drawing. In the Japanese Car Robots line, he was called Mach Alert. Prowl turns into a Lamborghini Diablo with Japanese police colors. The three brothers had designs that emphasized asymmetry and using large parts of the car as handheld shields or weapons.
