Plot

Gearhead, a part-cyborg adrenaline junkie, rides into Gotham in a souped-up racer. With the ability to take control of cars with his nano-technology, Gearhead is out to commit a series of crimes for thrills.

While partaking in a charity race Bruce Wayne witnesses Gearhead, a villain who can take over anything mechanical and transform it with nanomachines into a powerfully fast vehicle, steal the race's prize. Both Batman and Batgirl attempt to stop him, but when Gearhead destroys the Batmobile Bruce has to build a new one so he can take on the supercharged criminal and bring him to justice.—Left_back

A new villain, Gearhead, makes his first appearance robbing a charity race, and Batman soon finds himself forced to upgrade the Batmobile to keep up with the cybernetic bad guy.
