Hurtling down the track, careening around, over and through the competition, Speed Racer is a natural behind the wheel. Born to race cars, Speed is aggressive, instinctive and, most of all, fearless. His only real competition is the memory of the brother he idolized-the legendary Rex Racer - whose death in a race has left behind a legacy that Speed is driven to fulfill. Speed is loyal to the family racing business, led by his father, Pops Racer, the designer of Speed's thundering Mach 5.
