Kazuya "Kaz" Gordon hails from Earth, leading Team Jet (originally the Junior Earth Team). He trained in the Scan2Go system under Coach Ray at a dedicated Earth facility before venturing into intergalactic racing. Kaz sports dark blue hair in a ponytail and honey-colored eyes, typically wearing a blue vest with yellow and orange accents over a maroon t-shirt, white pants featuring red detailing, and blue shoes.

Kaz embodies a hot-blooded, competitive spirit, often prioritizing racing over basic needs like regular meals. Beneath his fiery exterior lies kindness, sympathy, and tenderness. He possesses a strong sense of justice and deeply reveres Zero, space's top racer. His personal motto, "faster than anyone," fuels his quest to become the universe's fastest racer, driving his journey through space for intense training and competition.

Throughout his development, Kaz confronts challenges like the threat of primary antagonist Ryu Kaizel, who aims to dismantle the Scan2Go committee and harness humanity's negative emotions to destroy the universe. His growth involves mastering strategic racing dynamics, including team-based and free-for-all formats where miniature autonomous toy cars blaze across colossal tracks. Success demands balancing speed with tactical deployment of power-up and turbo-boost cards to overcome obstacles. These experiences forge camaraderie with teammates Fiona Ryder, Diego Montana, and Myron Seagram, reinforcing themes of sportsmanship and resilience.
