Mach Wheel appears on the lower floors of the Yabbashah Block within Tartarus. They will typically increase their damage with Tarukaja before attacking. They may later be found in the second and third section of Caina within the Abyss of Time.
In Golden, it only appears on B6F. It resists fire and electricity, and is weak to wind. In battle, it may also use Masukukaja to make its attacks more accurate and prevent the player from hitting them as often. It may also drop Rose Quartz for trade at Shiroku Pub. Mach Wheels appear to spawn less frequently during rainy weather, so those attempting to obtain a High-Speed Gear for request #50 should consider visiting the Secret Laboratory on regular days.
Persona Q: Shadow of the Labyrinth[]
Mach Wheel appears in Nights 3 and 4 of the Inaba Pride Exhibit. It is weak to both Ice and Dark, attacks with single-target Physical skills, and can boost its attack with Power Charge. When defeated, it may drop Wheel Piece, Wheel Axle, and Wheel Tail. Wheel Piece is used to create the Militia Dagger for Koromaru and Yosuke, the Stealth Shirt male armor, and the Sleepless Mirror accessory. Wheel Axle is used to create the Suzumushi for Yukiko and the Aigis Armor v9 for Aigis. Wheel Tail, only obtainable by killing Mach Wheel with Wind, is required for the request "Obtain a Fluffy Tail," which rewards the Member Certificate upon completion, granting a 10% discount for Skill Cards. Wheel Tail is also used to create the Speed Eater for Zen and Rei.
