Spin / Tusk
Johnny first seeks Gyro Zeppeli's tutelage in the ways of the Spin in order to regain the use of his legs. Most often, Johnny channels the Spin by the use of his Stand, Tusk; developed first with the power of the Corpse's left hand, and further with Gyro's help. Its form varies, depending on the sort or style of Spin Johnny chooses to employ.
- ACT1 is awakened in the Devil's Palm when the corpse part combines itself with Johnny's left hand, manifesting his Stand with the ability to spin his nails and fire them akin to bullets, and regrowing his nails in seconds.
- ACT2 manifests when Johnny shoots a nail whilst incorporating the Golden Rectangle in a fight against Sandman. Despite the longer regrow time, the nails possess more power and a new ability that lets the holes of the bullets follow the target for a small amount of time.
- ACT3 is the final "base" form for Tusk and manifests when Johnny shoots himself with a Golden Rectangle-empowered nail, enabling him to transfer parts of his body through the holes to shoot from different directions. It was awakened by an advice from Jesus in a fight against Axl Ro.
- ACT4 manifests itself as a result of Johnny utilizing Slow Dancer's power combined with the golden rectangle, which enables Johnny to fire super spin nail-bullets that have infinite rotation. ACT4 possesses the power to force open D4C Love Train's dimensional wall, and trap anyone hit by it to a single spot indefinitely.
Johnny Joestar has been described as a genius jockey, being one of the favorites of the Steel Ball Run race. His skill allows him to ride across many types of terrain, and challenge even fellow genius jockey Diego Brando. Johnny possesses great knowledge of his horse Slow Dancer, notably its abilities and limits, being able to gauge what Slow Dancer will be capable of at any moment.
Johnny Joestar proves himself a competent Stand User, being able to use Tusk's abilities to the fullest. Johnny Joestar has occasionally used the terrain and his enemies own power against them, and was perceptive enough to quickly deduce Alternate Diego's time stopping power.
When using Tusk, Johnny proves to possess great marksmanship, being able to hit little and/or moving targets, even if firing from odd angles and perspectives, such as when Tusk ACT3 separates his hand from his arm.
