"she's a saint to go on living with that man"
 '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 any display of sentimentality in life and ultimately defied him by going to America.[16]'

Out of combat, Gyro also possesses an eccentric personality and is particularly flamboyant. Gyro has a penchant for gags involving puns or an inexplicable brand of humor from bad puns[20] to gags defying all logic,[21] frequently telling such jokes to Johnny in the spur of the moment and created a song about cheese, singing it to Johnny and being happy that he appreciated it.[22] 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.[23] The mere fact that he engraved his teeth with the message "Go! Go! Zeppeli" already exposes his flamboyantly confident nature.[23] Humorously, Gyro also keeps a teddy bear with him, being fond of it enough to keep it even during the Steel Ball Run,[24] 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.
