Gen Kondo, a prominent racer in Professor Oogami's group, dominates competitions through aggressive tactics and a destructive racing approach. He pilots Brocken Gigant series Mini 4WD cars—utilizing the standard model, a "Black Special" variant during the World Grand Prix arc, and the Brocken Gigant Black Metallic in *Return Racers!*. His Ax-Crazy personality drives an obsessive urge to annihilate opponents' vehicles, often prioritizing sabotage over strategic efficiency in Stupid Evil decisions. A habitual lollipop carrier hints at his Sweet Tooth. Despite briefly recognizing victory could be achieved without destruction during one race—prompting temporary restraint—he displays Aesop Amnesia by instantly reverting to his ruinous methods. In *Return Racers!*, years after the original series, Gen resurfaces with the upgraded Brocken Gigant Black Metallic, confirming his continued racing involvement while lacking explicit evidence of evolved philosophy or personal growth.
