Episode Title:
Crash and Burn.
Episode Description:
Rex befriends a group of motorcycle racers who utilize performance-enhancing nanites which are negatively affecting them. Wishing to end the nanite enhancement trade, Rex tracks the nanites down to their source, a "biking guru" named Valve who challenges Rex to a race to determine the fate of the nanites. Meanwhile, Rex confides in Six that he is incapable of manifesting more than one machine at a time. Six deduces this as a mental block, and encourages Rex to overcome it. During the race, Rex is successfully able to manifest two machines, and defeats Valve.
