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".
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.

Gyro's main outfit for the first half of the race. He wears a dark short-sleeve shirt adorned with a grid of miniature steel balls along with two extra balls, one on each shoulder, and three straps wrapped around his upper arm; dark wristbands that cover half of his forearm and the back of his hand; a cape wrapped around his shoulders and split into three segments; chaps with spurs on top of a dark pair of pants which are exposed at the calves and thighs; a large belt with two large buckles that feature hands pointing to his crotch and which are designed in the ratio of the golden rectangle and two holsters for his Steel Balls; a wide-brimmed cowboy hat with slits all around that each extend from the brim to the crown; and slit goggles sitting on the crown of his hat.
A winter outfit that is overall identical to his main outfit except that the straps of his cape are covered in fur and that he wears a light colored long-sleeve shirt underneath his main shirt.
A thick, long-sleeve jumpsuit worn in severely cold weather. The suit is lightly colored other than the chest, which is a dark color, and multiple large ovals designed like Steel Balls cover the chest in a "Y" shape along with two others on the shoulders. The upper arms of the sleeves are puffy and segmented like a parka, and he also wears gloves, a turtleneck sweater, his usual cape, and dark pants which can be seen at the calves underneath the suit. A collar made of fur is also worn around his neck for warmth. A flap of cloth is attached to his hat to cover the sides and back of his head, and his belt with his holsters is looped through the suit itself.
Gyro's final outfit during the race is the same as his initial outfit except that he wears a thick undershirt with its sleeves and collar visible and a fur collar worn over his shirt. Additionally, his shirt is depicted without the striped grid it had for the most part previously, with the balls covering the torso arranged in general rows rather than a grid.
