Gyro Zeppeli | Campsite

Appearance: Gyro is a man of average to above-average height and medium to athletic build. He has long hair that reaches mid-back, light-colored eyes, and square patches of facial hair lining his jaw, four on each side. He either wears grills or has chiseled into prosthetic teeth the phrase "GO! GO! ZEPPELI", which are said to be gold. Throughout the Steel Ball Run race, Gyro wears a variety of outfits to suit the weather of the current location. However, they all maintain the same key elements and motifs of his wide-brimmed hat and slit goggles, a dark shirt studded with miniature steel balls, a cape wrapped around his shoulders that splits into three segments, and his large belt with special holsters for his two Steel Balls.

Personality: Gyro is a cocky and flamboyant executioner marked by the harshness of life, who participates in the Steel Ball Run for the sake of a young boy who he believes was wrongfully sentenced to execution in his home country.

Gyro initially appears as an aggressive contestant in the Steel Ball Run race. Unlike other competitors, Gyro looks to seize first place above all else, rushing ahead of everyone and then fending off anyone who challenges him. He also has a tendency to take dangerous shortcuts. Gyro is a rude man, deriding the vast majority of those he meets with insults and mocking commentaries. The only person for whom Gyro had any degree of respect is his stern father Gregorio Zeppeli. Gyro's overconfidence extends to his fights, during which Gyro is prone to mock his enemies in some way or say something brash.

Gyro is particularly proud of his mastery of the Spin, a family technique involving the rotation and throwing of steel balls to various effects, and hails the Spin as the acme of human skill. As an executioner and otherwise confrontational man, Gyro is not afraid to use violence even in a lethal fashion. However, Gyro doesn't have the same ruthlessness as Johnny and initially doesn't seek to kill his enemies if he deems it unnecessary. Notably, Gyro did try to discourage a thief from fighting with him and only used his Steel Balls to make the man shoot himself if he ever drew his gun, instead of directly killing him. Gyro nonetheless possesses an altruistic side, and likes to help anyone who needs his assistance, most notably the paraplegic, Johnny, to whom he taught the Spin technique and helped acquire the Holy Corpse Parts, or Marco, the helpless child whose death sentence Gyro seeks to appeal by winning the Steel Ball Run. Gyro would often clash this side with the authority of Gregorio Zeppeli, who disapproved of any display of sentimentality in life and ultimately defied him by going to America. Johnny originally said that Gyro didn't have the drive and determination necessary to get things done. The jockey argued that because Gyro inherited everything he had as an upperclassman and heir of the family Spin technique, he didn't have the kind of selfish hunger born from suffering which was crucial in the race. True to that, Gyro Zeppeli initially raced out of altruistic concern for Marco, and primarily relied on tricks to prevail in the race. During his battle with Ringo Roadagain he bent his original motivations into a more personal goal, the path to see for himself whether Marco deserved to be executed and who exactly the Corpse was. After that, Gyro switched to a slightly less cocky behavior, and focused seriously on his battles. In his horse riding, Gyro switched to a more personal style, instinctively choosing his own route instead of the "shortest path", enabling him to even outmatch Diego in the race.

Out of combat, Gyro also possesses an eccentric personality and is particularly bombastic. Gyro has a penchant for gags, involving puns or an inexplicable brand of humor from bad puns to skits defying all logic, frequently telling such jokes to Johnny in the spur of the moment and created a song about Mozzarella cheese, singing it to Johnny and being happy that he appreciated it. He also has a fondness for dramatic gestures and quotes, saying that the Goddess of Victory was riding with him and that she would retract her favor if he ever let another woman ride with him. Unlike Johnny, Gyro frequently grins, exposing his metal teeth in the process. The mere fact that he engraved his teeth with the message "Go! Go! Zeppeli" already exposes his ostentatious nature. Humorously, Gyro also keeps a pink teddy bear with him, being fond of it enough to keep it even during the Steel Ball Run, although he leaves it at one point. However, mimicking his own father, Gyro can be stern and dignified when he talks about the Zeppeli Spin technique.

Heavily influenced by Gregorio's teachings about the uncertainties in life - using a "tennis ball over the net" metaphor - and the Steel Ball's power being nothing short of miraculous, Gyro has a somewhat optimistic outlook on life and is convinced that he can overcome setbacks, even if they'd need a miracle to overcome, as long as he follows a virtuous path. Nonetheless, following the "tennis ball over the net" belief, Gyro is aware that failure is just as likely. This ideology is repeatedly somehow confirmed with numerous coincidences and miracles helping him throughout his journey and alternatively working against him, culminating in Marco being freed without his intervention but dying of a cold later.

Gyro is a womanizer, one flashback narrating an affair with a patient and he is shown flirting with pretty girls. On the other hand, the first time Gyro and Johnny meet Lucy, he refuses to let her ride with him and states that "no woman (will) ride my horse". He later explains that "Lady Luck" would be jealous if he let "another woman" ride with him.

Gyro has a few tics of language. For instance, he has a signature "Nyo-ho-ho!" chuckle and he usually shouts out "ORA!" when he hurls a Steel Ball in combat
