Gyro has a cocky and flamboyant personality, appearing to have a high opinion of himself. However, he can be driven by emotions for other people and become realistic and serious when a problem presents itself. Like most Manga archetypes, Gyro is incredibly intelligent when he needs to be. His most distinguishable body features are his long hair, western hat and his gold teeth which have "GO! GO! ZEPPELI" displayed on them, revealed whenever he smiles at someone. His signature laugh/chuckle is "Nyo ho ho ho~".
