2. Hot Wheels: World Race
Founder and owner of the Scrim Corporation, who creates racing technology allowing him to create the cars. He discovered Highway 35 in ancient writings and inscriptions. Though he seems to be sinister, he actually only wants to use the Wheel of Power as a source of clean energy. He is, however, very manipulative, only using the World Race as a pretext to retrieve the Wheel.
3. Hot Wheels: AcceleRacers
레이싱 도중 부상을 입어 외골격의 도움 없이는 움직일 수 없게 되었다.Dr. Tezla abandoned the Cube and went into hiding in the AcceleDrome where he conducted research centered on the Wheel of Power. Once he discovered the nature of the Wheel of Power and the Racing Realms, Dr. Tezla recruited former World Race drivers to help him compete in the Racing Realms for the power of the AcceleChargers. Hunted by Gelorum and the Racing Drones, Dr. Tezla is a very secretive man sharing information only if he decides the person needs to know it. This generates some distrust among those he leads – especially Kurt Wylde who has never trusted Tezla. Despite his secretive nature, his most trusted companion is Gig, a hovering robot. Dr. Tezla was crippled in the attempt to keep the Drones from the Wheel of Power – he now walks and stands with the aid of a motorized exoskeleton. Dr. Tezla also has some sort of connection with the Silencerz. When questioned about this apparent connection, he claims to be the victim of theft. We later learn that Dr. Tezla used to work for the Silencerz, but then left them taking some of their technology, including Gig. Revealing their technology, Dr. Tezla took credit for it all and became rich.
