Kanji Gozu commands the Mobile Rescue Police and Mobile Assault Police, wielding full authority over the Drive Head project. Known for his serious, pragmatic demeanor, he maintains a respected yet approachable presence within the organization. His leadership spans high-stakes operations, from overseeing the inaugural deployments of Drive Heads 02 and 03 to greenlighting the Mk-II upgrade after the Sonic Interceptor’s destruction during Dr. Karigari’s interference.

He navigates crises with decisive authority, sanctioning probes into the Black Chips and the Evil AI. During the Black Chips incident, he withstands a physical assault from a mind-controlled Hayato Isurugi, emerging unscathed as tensions defuse. Faced with the drivers’ proposal to infiltrate the Tower of Babel, he reluctantly authorizes a risky scheme involving fabricated emergencies to secure access.

In the film, he falls victim to Karigari’s deception, receiving falsified warnings about Terra’s threat via a disguised Saionji. When the Drive Heads’ Justice Circuits falter, he advocates temporarily substituting drivers with Mobile Assault Police pilots, prioritizing mission readiness despite escalating dangers. He backs Gou Kurumada’s judgment amid Terra’s onslaught, defending Karigari’s controversial Cyclone Interceptor modifications despite skepticism.

Gozu’s strategic collaborations with figures like Saionji and Jō Kurumada underscore his role in joint crisis resolutions. His arc culminates in him stepping into command during pivotal missions amid leadership voids. His appearance and role in the 2018 web series remain unspecified.
