Gou Mifune

Ready to take on the most treacherous courses, Speed faces the most ruthless villains as he competes in races around the world in such real-life destinations as Japan, Egypt, and Mount Rushmore, and other worldly places like Sandoland, Abalonia, and Flathill. Speed races blind or without brakes, he sets a new land speed record and races the car no one could drive.

Although important, winning races isn’t Speed's primary goal. Sometimes, he will intentionally lose a race to aid a total stranger, but more often, he will win a race while aiding the likes of Inspector Detector in whatever mysterious situation he encounters.
