[TUSK]
Tusk (牙 Tasuku?) is the Stand of Johnny Joestar, featured in Steel Ball Run.
Quick-Spin Nails: Tusk ACT1 grants Johnny's ability to Spin his fingernails at a high speed and shoot them as projectiles that he calls "Tusks", far more precise and powerful than the average bullet. Notably they are capable of carving a tree into a humanoid shape within seconds. Once Johnny shoots a fingernail, they take a short time to grow back.
Ten-Aureal Nails: Once Johnny learns to Spin the fingernails with aureal rotation, thus bringing Tusk to his second form, he can shoot fingernails that are significantly more powerful. The holes these shots produces move: if, for example, he shoots and produces a hole on a table, he can move the hole on the surface of the table and whatever touches the table's surface. However, the hole leaves a track behind it as it moves. The holes will aggressively chase any target designated by Johnny.
Through the Hole: By shooting himself with a fingernail Spinning with aureal rotation, Johnny is able to suck his body into the infinite "location" in which the spiral spins into its smallest possible point. Anything other than Johnny's body is destroyed by entering through the infinite hole. Johnny is also able to send a part of his body through the hole, moving it away from his body. This way he can shoot fingernails from different directions, by sending his hands or fingers through the holes.
Infinite Rotation: This Super Spin can pierce through multiple universes, and influence gravity. The damage caused by the rotation is also infinite and will not end unless Johnny were to apply another similar rotation moving the other way, resulting in them cancelling each other out.
When hit by one of Johnny's nail bullets, ACT4 imbues targets with infinite Spinning motion, making them Spin internally. That Spin goes on forever and never leaves the person or their Stand, forcing them to return to the place where they were hit, or its equivalent in each parallel dimension. Tusk can move through both D4C's Love Train and can move through THE WORLD's stopped time to reach its target which makes it acausal (unaffected by space or time). Tusk can seemingly open portals through space and travel through them as was shown in Johnny's battle with Diego Brando from another universe.
The Spin is also transferable between objects, as the Diego Brando from another universe cut his leg off and threw it to Johnny, transferring the infinite rotation to its user. Another example is when Funny Valentine went into a passing car trying to run away from Tusk, the infinite rotation nearly instantly destroyed it, coming back to Valentine.
