Speed King Max (スピード王マックス, Supīdo Ō Makkusu) (9), also known as the 'Speed King of Space,' was a champion space car racer who was admired and respected by children throughout the universe, including Dapp. Though notable for his triumphant career, it seemed to come to an abrupt end when he appeared to die crashing into a vending machine in space.
In actuality, he crash landed on a planet occupied by members of the Universal Reckless Driving Tribe Bowzock, where he was encountered by Deputy Leader Zelmoda and Inventor Grotch. Grotch brainwashed and deformed him using Forgetfulness Water-Gun, making him into KK Esu (クークーエス, Kū Kū Esu), the best dish-washer of the Bowzock. In this form, he could blast lasers from his oversized eye and create an ear-piercing "squeaky clean" hurricane. After being saved by the Carranger and returned to his original self, he died protecting Dapp from Zelmonda. Dappu sat next to his corpse on RV Robo's hand as his spirit went to heaven.
