Masked in mystery, the secretive “Racer X” seems to always be watching Speed Racer’s back, and with good reason. Racer X is actually Speed’s older brother Rex, who after crashing one of Pops’ cars at 18 and being told he should never race again, estranged himself from his racing family. Also, a top secret Interpol agent Racer X drives his car - the Shooting Star - in the same races as Speed so he can keep a protective eye on his little brother, and a watchful eye on the villain of the day. The JoyRide Entertainment Series features detailed models of vehicles from television and film. These fully assembled models are crafted using die-cast metal with some plastic components.
