Spoiler alert!

This section of the article may contains details concerning the progression of the plot. If you do not want it to be spoiled for you, skip this section!

In the series, the Proto-Saber JB was a Mini 4WD car created by Professor Ogami, designed to surpass Professor Tsuchiya's own creations. The front roller angle, gear ratio and various body parts can be adjusted via J's own remote-control brace. The adjustable body parts allows the Proto-Saber to do air brakes, but also allows it to fire concentrated burst of air to blow any Mini 4WD cars away.

During the Tokichi Cup, J renounced his battle racing ways and destroyed the remote-control brace on his own after he recovered his Proto-Saber from the sea in which he was almost drowned. The Proto-Saber no longer worked as J had stripped off its battle race components, but was later restored as a normal race car with parts from Go and his co. It was later revealed in the series that Ogami created not one, but multiple Proto-Sabers, and even made a mass-produced version of the car.

It is unknown what happened to J's Proto-Saber after it was replaced by the Proto-Saber Evolution.

Jun and her Proto-Saber, as seen in Return Racers!.

In Return Racers!, Jun was seen using her own Proto-Saber to race against Tsubasa's Wing Magnum. Jun's Proto-Saber has the 'JUN' on the rear spoiler.
