Gyro Zeppeli (ジャイロ・ツェペリ Jairo Tseperi), born Julius Caesar Zeppeli (ユーリウス・カイザー・ツェペリ Yūriusu Kaizā Tseperi) is a primary ally featured in the seventh part of the JoJo’s Bizarre Adventure series, Steel Ball Run.
Gyro is a master of the Spin and an executioner hailing from the Kingdom of Naples. He joins the Steel Ball Run race to win amnesty for a child he is assigned to execute. Gyro’s signature weapons are his special Steel Balls that produce and manipulate the Spin – the mastery of which later allows him access to the senescence-inducing Stand Ball Breaker.
Gyro is a man of average to above-average height and medium to athletic build. He has hair that reaches mid-back, light eyes, square patches of facial hair lining his jaw, and (in illustrations) often painted lips. He either wears grills or has chiseled into prosthetic teeth the phrase “GO! GO! ZEPPELI”.
Gyro’s basic outfit consists of a short-sleeved studded black leather coat, leather pants, and cowboy boots. He wears a belt, the buckle of which bears a pair of hands pointing to his crotch, and at his hips a pair of special holsters for his Steel Balls. He wears a wide-brimmed hat, with slits on the the crown and the brim that let light and air filter through. Situated around the crown of his hat are a pair of slit goggles. Depending on the weather he may wear his goggles, in addition to a scarf.
