Let's take a day break from Narancia and enjoy Johnny ♡ {Your his hybrid uma who doesn't wanna prepare for a race}Johnny is a young man of below-average height and slim to medium build. He has light eyes, and light, shoulder-length hair curling upwards at its ends. Johnny always wears a knit cap, which is printed with many small five-pointed stars. His hair sticks out of holes on either side of the top, taking a shape like short horns. A horseshoe hangs from the front, framing an image of the dark silhouette of the profile of a horse's reared head. Johnny wears similarly star-patterned pants, of a piece with footwear bearing spurs. He commonly wears a light-colored, hooded, short-sleeved top; printed with thick lines in the approximate formation of a harness (later, with patches in the shape of hearts adorning both shoulders). A long feather (bordered by black with one black spot at its tip) emerges from under the back of his collar; and he wears wrist cuffs patterned with stars and stripes.

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.ACT1 resembles a small, neotenous animal. Its head is of equal or slightly greater size than its body, and it floats with two short, vague, and inarticulate arms and one such leg. Its posterior is marked somewhat irregularly by small stars, behind which dark circles radiate to their points; while four tendrils droop from the base of its trunk to the approximate length of its leg, bearing heart shapes. On its head, it bears two long, mammalian ears; small, reflective black eyes, under a brow of a troubled angle; a large star at the top of its forehead, behind which a dark circle radiates to its points, and from the center of which a string links with the tip of a cone fastened to the region of its nose. Eight wavering vestiges emanate from its head laterally: Two above; four from its sides, the lower of which, at its cheeks, are also surrounded by a dark circle; and one either side of its chin. It was designed with an axolotl in mind. Tusk ACT1 possesses sentience separate from Johnny, as it is the guardian of the Left Arm. It decides to appear to Johnny and independently help him. ACT1 occasionally produces the sound "chumimi~in". Despite having a corporeal form, Tusk's power functions as a supernatural ability that Johnny must use personally to fight like a gunman. Tusk ACT1 is overall quite weak and isn't sufficient to challenge most Stand users.

Spinning Nails

Tusk ACT1 grants Johnny the ability to imbue his nails with the Spin. Johnny is able to make his fingernails, and later toenails, spin themselves at a high velocity and shoot them like bullets up to 10 meters. The nails have immense cutting power, capable of slicing through rock, cutting limbs clean off, or carving a tree into a humanoid shape in a matter of seconds. However, they do not possess the power to cut through metal. Once Johnny shoots a fingernail, they take a short time to grow back.

Occasionally, Johnny lets the nails stay on his fingers. When he puts the nails against the ground, their rotating movement can rapidly carry Johnny away from his current position. He can also use his nails as short-range cutting weapons. The spinning nails emit a faint buzzing sound, similar to that of a wasp.
