Gray Stanbeck, formally named Gregory Stanbeck, works as a mechanic for the Aoi ZIP Formula team, specializing in advanced racing machinery. His expertise centers on managing the bio-computer-equipped Ogre AN-21, where he plays a pivotal role in guiding Jotaro Kaga to master the vehicle’s unstable systems. Collaborating with Phill Fritz, he addresses the hazardous bio-computer mechanisms that endanger both driver and team.

His professional rapport with Kaga extends beyond technical support, evolving into a partnership anchored in mutual trust during high-pressure scenarios. This alliance proves critical when Kaga withdraws from races to focus on training with the Ogre, relying on Gray’s mechanical insights to counteract the machine’s lethal legacy.

Following the final Grand Prix, Gray departs Japan alongside Kaga and Phill, marking the end of their shared endeavors.
