In Video Games
Gyro appears as a support and help character. His supports summon him to throw his Steel Balls at the opponent, inflicting either the paralysis or shocked status effects, and his Help Koma increases the affected battle character's movement speed.
At the time of the game's release, Steel Ball Run was listed as a different franchise separate from JoJo's Bizarre Adventure; Gyro appears as the series' main representative character.
Gyro appears again as a support and help character. While his support attack remains the same, his Help Koma now increases the rate at which the affected battle character's special attack gauge replenishes.
Due to Steel Ball Run having been confirmed as Part 7 of JoJo's Bizarre Adventure, unlike the previous game, Gyro is now listed as part of the JoJo's Bizarre Adventure franchise, and is one of two Part 7 characters in the game, alongside Johnny Joestar.
As a Part 7 character, three parts of the Holy Corpse appear scattered on stages when he, Johnny, or Valentine are used, which they can pick up to receive blessings that boost their performance in combat. Along with Johnny, Gyro is one of the only two characters in the game who use the "Mounted" Style. This Style allows him to get on and off his horse, Valkyrie, slightly changing the moves available to him. Gyro must be unmounted in order to pick up the Corpse Parts.
Exclusive to Gyro are the Steel Ball Icon and the Spin Gauge, both displayed about the Heart Heat Gauge. The Steel Ball Icon display how many of Gyro's two Steel Balls are in his possession. Gyro's Steel Balls will automatically return to him after a short delay once thrown, hitting the opponent if they are between the Steel Balls and Gyro. The Spin Gauge displays how much Spin Energy Gyro has.
- Spin: Gyro charges the Spin Energy into his Steel Balls, leaving him open to attack but replenishing the Spin Gauge. This skill's function is similar to the "Ripple Breath" skill possessed by all Ripple-Style Users. When filled completely, Gyro enters Golden Spin Mode, increasing the damage of all attacks involving his Steel Balls, and allowing them to hit multiple times per attack, better improving Gyro's ability to combo from them. The Spin Gauge is then turned into a timer, slowly draining to zero, and Gyro is unable to use this ability again until it empties completely.
- I toughened my skin: Gyro places a Steel Ball imbued with the Spin to his chest, causing his skin to wring and toughen. This skill is used to instantly block attacks using the Heart Heat Gauge in place of the Guard Gauge, and will last as long as the Style button is held, or until the HHG empties.
- Spin, spin!: Gyro throws a Steel Ball at the opponent as a projectile, hitting them multiple times. Gyro can throw both of his Steel Balls in succession, but both need to be available to do so. (Comboable through Puttsun Cancel)
- Raaaaugh!: Gyro throws a Steel Ball to the ground, before it proceeds to quickly move toward the opponent, carried by the power of the Spin. If it hits the opponent, the Steel Ball will release its Spin energy upward, blowing them into the air. (Comboable)
- I'm gonna throw it away!: This move can only be used when Gyro has both Steel Balls available. Gyro drops both Steel Balls to the ground, and using the Spin, the two kick up debris to shoot at the opponent, sending them flying if hit. (Comboable)
- Run wild, run free!: This move can only be used when mounted. Valkyrie spins around stomping, hitting the opponent multiple times and knocking them off their feet if hit. This attack can hit a downed opponent. (Comboable through Puttsun Cancel)
- Winds from Mexico: This move can only be used when mounted and at a distance. Gyro, using a Steel Ball imbued with the Spin on Valkyrie's rear, causes the horse to gallop forward at a fast speed. If the opponent is hit, they are knocked high into the air. (Comboable through Puttsun Cancel)
- Throw - Can only spin for a bit!: Gyro pushes the opponent off balance, before using Spin energy to form a spinning ball of compressed air between his hands and blasting them with it.
Gyro receives a new blessing every time he picks up one of the three Holy Corpse Parts, but if knocked down, loses it as he drops the part.
- Gyro gains access to the ability Scan: Gyro throws a Steel Ball at the opponent as a projectile, hitting them multiple times. If the button is held long enough and let go, or until the Steel Ball hits the opponent, the Steel Ball will remain hovering in the air. If used a second time, Gyro throws his remaining Steel Ball at the one hovering, causing it to ricochet towards the opponent and hitting them for substantial damage.
- Any one of Gyro's moves that utilize Steel Balls can only be interrupted by Throws/HHA/GHA.
- Gyro's attack power is boosted, increasing his damage. Golden Spin Mode is also permanently active; The Spin Gauge will never run empty.
Gyro's HHA, "One moooore shot!", throws a Steel Ball with a large amount of Spin Energy infused into it. If it connects, Gyro throws a second one as the two Steel Balls shred the opponent's face and send them flying. The HHA will automatically retrieve a single Steel Ball upon use, and its damage will be increased if Golden Spin Mode is active.
Gyro's GHA, "Ball Breaker", will instantly fill the Spin Gauge to max, automatically activating Golden Spin Mode. The GHA can only be performed while mounted, but will automatically summon Valkyrie when used unmounted. Gyro on horseback, launches a singularly powerful Steel Ball imbued with the power of the Complete Golden Spin Energy. If it lands, the Steel Ball will shred into the opponent's torso, before Ball Breaker appears in front of it. The Stand finishes by spinning and funneling itself into the Steel Ball, dramatically increasing its power and speed. The entrance of the Stand into the Steel Ball shredding the opponent at point-blank range generates a massive green burst.
If Valentine is falls victim to the GHA, a unique special scene plays where Valentine attempts to protect himself with D4C Love Train, only for Ball Breaker to penetrate and fly through the dimensional wall, recreating the scene from the battle in the manga. Ball Breaker will zoom past Valentine and D4C's face, the two bracing themselves, before exploding in a blast of Complete Golden Spin Energy.
Most of his alternate costumes are based on manga and chapter covers. Gyro's first taunt makes him smile while saying his catch phrase "Nyo~ho" as the camera zooms in on his iconic grills reading "GO! GO! ZEPPELI" and his second taunt will make Gyro sing his Mozzarella song.
In the alternate timeline he is shown to have survived the fight with Valentine and is fighting along-side Johnny against the alternate Diego Brando.
He is paired with Jolyne Cujoh in the Eyes of Heaven Tournament, beating Muhammad Avdol and Koichi Hirose in the first round and Jotaro Kujo and Vanilla Ice in the second. Making it to the semifinals, they beat Jonathan Joestar and DIO in the first round and Bruno Bucciarati and Trish Una in the second. Ultimately, they were defeated in the final round by Kars and Pet Shop.
- Araki personally liked the Jonathan-Zeppeli relationship from Phantom Blood and wanted to retell it again for a longer coming-of-age story. He chose to make Johnny and Gyro around the same age so they could be less formal and more friendly than their original counterparts. Gyro's random jokes and Johnny's trivial use of his spinning nails were included to reflect this concept.
- Gyro was able to see Stands before he achieved one of his own. He is the first and so far only Zeppeli to have a Stand.
- In the Italian edition of SBR, Gyro's name is written as "J.Lo", in a reference to American-Latino singer Jennifer Lopez. This is also a slight pun on the fact that the pronunciations of "Gyro" and "J.Lo" in Japanese are almost identical.
- In the French edition of SBR, Gyro's name is written as "Jayro".
- Giro means "Rotation/Spin" in Spanish.
