Born Julius Caesar Zeppeli, but more commonly referred to as "Gyro Zeppeli." 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 metal teeth which have "GO! GO! ZEPPELI" displayed on them, revealed whenever he smiles at someone. His signature laugh/chuckle is "Nyo ho ho ho~." Note that the "Caesar" in his name is pronounced in the traditional Latin way, more akin to the German "Kaiser." This is distinct from Caesar Anthonio Zeppeli from JoJo's Bizarre Adventure Part 2, whose name is pronounced in the modern English way.
