What You'll Learn

Johnny Joestar's character and backstory
Johnny Joestar is a protagonist of Steel Ball Run and a minor character in JoJolion. He is the seventh JoJo of the JoJo's Bizarre Adventure series. Johnny is a former horse-racing prodigy turned paraplegic after being shot in the spine. Despite his condition, he joins the Steel Ball Run race to uncover the secret behind Gyro Zeppeli's Steel Balls, as they are the only thing that can restore his ability to walk. Over the course of the race, Johnny becomes a Spin User and a Stand User when he acquires Tusk.
Johnny is a well-built young man with light eyes and light, shoulder-length hair that curls upwards. He almost always wears a knit cap printed with many small five-pointed stars. He has been described as a genius jockey and was one of the favourites of the Steel Ball Run race. His skill allows him to ride across many types of terrain and challenge fellow genius jockey Diego Brando. Johnny possesses great knowledge of his horse Slow Dancer, including its abilities and limits, and is able to gauge what Slow Dancer is capable of at any moment.
Johnny's life took a tragic turn when he was shot in the spine during an altercation, resulting in paraplegia. Before the incident, he was a successful jockey with a bright future. However, as he could no longer ride a horse, he was shunned by those around him and spent almost two years alone in a hospital. Johnny's toxic relationship with his father, George Joestar, and the guilt he felt over the death of his older brother, Nicholas, affected him mentally. Despite having almost everything, he could not earn his father's respect.
Johnny's power, Tusk, is considered one of the most cringe-inducing abilities in media. It involves shooting his fingernails like bullets, leaving the raw flesh underneath exposed. While his nails do grow back, the ability is still considered disturbing and uncomfortable by many. Some fans have speculated that Johnny may not feel pain when using this ability, either due to the nature of the power or his depressed mental state.

How Johnny's fingernails grow back
Johnny Joestar, one of the main protagonists of Steel Ball Run, has the ability to shoot his fingernails with axial rotation, thanks to his power called Tusk. This leaves his fingers exposed and raw, with the nails taking several minutes to grow back. However, Johnny can accelerate the growth of his nails by consuming certain herbs or drinking tea, particularly mint and chamomile.
Now, let's delve into the process of how Johnny's fingernails grow back and the factors that influence their regrowth.
Firstly, it's important to understand that nails, including fingernails, grow from the nail matrix, a part of the nail bed located underneath the skin. The matrix contains special cells that produce new nail cells, pushing older cells up and out, eventually leading to the formation of nails. This process of cell generation and replacement occurs continuously, resulting in the growth of nails over time.
The regrowth of Johnny's fingernails can be influenced by various factors. One crucial factor is overall health. If Johnny is sick or malnourished, his nail growth may slow down. Hormones can also play a role, as hormonal changes during pregnancy, for example, can lead to faster nail growth. Additionally, certain medications, such as chemotherapy, can temporarily affect the nail matrix, causing Beau's lines or slowing nail growth.
In terms of specific care for his fingernails, Johnny can promote healthy regrowth by keeping the nail bed area clean and dry. Applying petroleum jelly and covering it with an adhesive bandage can help protect the exposed area and keep it moist, facilitating the regrowth process. He should also be vigilant for any signs of infection, such as increasing heat, redness, pain, tenderness, swelling, or pus.
It's worth noting that while Johnny's fingernails may grow back, the process can take several minutes to hours, depending on various factors, including his overall health and any injuries sustained.

The power of Johnny's nail bullets
Johnny Joestar, one of the main protagonists of Steel Ball Run, has a unique ability called Tusk, which allows him to shoot his fingernails as bullets. This ability is referred to as "nail bullets" or "finger nail bullets." While it may seem painful to shoot one's fingernails, Johnny does not appear to feel any pain when using his power, and he does not even bleed. His fingernails also grow back, although it takes several minutes, and he can accelerate this process by consuming certain herbs or drinking tea.
However, as Johnny's Stand evolves, so does the power of his nail bullets. With Tusk ACT2, Johnny's nails gain enhanced destructive power and new properties. By incorporating the Spin's Golden Rectangle, his nails rotate around his fingers like axes, giving them a drilling property that dramatically increases their impact. This upgrade allows Johnny to cause massive damage with a single shot, creating large blast zones. Additionally, the nail bullets gain the ability to disappear after landing, leaving behind bullet holes.
The true potential of Johnny's nail bullets is unlocked with the evolution of Tusk ACT3 and ACT4. With these forms, Johnny can create wormholes through space by shooting himself with a Spin-imbued nail. These wormholes serve as portals, allowing him to reposition himself or key parts of his body, such as his shooting hands. By attacking from unexpected angles, Johnny gains an element of surprise and tactical advantage over his opponents. Furthermore, anything sent into the wormhole will exit through the other end, providing Johnny with additional offensive capabilities.
In conclusion, the power of Johnny's nail bullets lies not only in their raw destructive force but also in the unique abilities they grant him. The evolution of his Stand, Tusk, enhances the properties of his nail bullets, increasing their damage output and providing him with strategic options in combat. The combination of speed, power, and unpredictability makes Johnny a force to be reckoned with in the world of JoJo's Bizarre Adventure.

The Spin and its effects
Johnny Joestar, one of the main protagonists of Steel Ball Run, is a Spin User. The Spin allows Johnny to shoot his fingernails with axial rotation, imbuing them with the power of the Golden Rectangle. This causes the fingernails to rotate around his fingers like axes before he shoots them, giving them a drilling property that increases the power of his shots. The Spin also enables Johnny to perform mundane tasks, such as grating cheese, winding spaghetti, and brushing his teeth.
When Johnny shoots his fingernails with the Spin, they take several minutes to grow back, although he can accelerate this process by consuming certain herbs or drinking tea, such as mint or chamomile. The Spin's effects on Johnny's fingernails are enhanced in different forms of his Stand, known as Tusk. In Tusk ACT2, the regrowth time of his nails increases, but the shots gain enhanced destructive power and new properties. For example, the nail shots create bullet holes that remain for a short time, and anything that enters the holes will be severed.
In Tusk ACT3, Johnny shoots himself with a Spin-imbued nail, enabling him to transfer parts of his body through the holes and attack from different angles. This ability is limited by how long the holes can persist in the world. Finally, in Tusk ACT4, Johnny can fire nail bullets with infinite rotation, granting him super armour during the attack.
Overall, the Spin gives Johnny the ability to shoot his fingernails as bullets, enhancing his combat capabilities and allowing him to perform everyday tasks. The different forms of his Stand, Tusk, further evolve the effects of the Spin, increasing the power and utility of his fingernail shots.

Other uses of Johnny's fingernails
Fingernails have multiple uses, and this is true for Johnny's fingernails as well. In the JoJo's Bizarre Adventure series, Johnny Joestar, one of the main protagonists, has the ability to shoot his fingernails as bullets. This ability, called Tusk, is a powerful tool that Johnny uses in combat. However, aside from their use as projectiles, Johnny's fingernails have other purposes and implications, both within the narrative and in a broader context.
Medical Diagnosis and Health Monitoring:
Fingernails, including Johnny's, can provide valuable insights into an individual's health and well-being. Certain changes in the appearance of fingernails, such as discoloration, thinning, thickening, brittleness, splitting, grooves, and other abnormalities, can indicate underlying medical conditions or nutrient deficiencies. Doctors often assess fingernails as part of the diagnostic process. In Johnny's case, monitoring his nail health becomes especially crucial due to the frequent regrowth required after shooting his nails.
Grooming and Hygiene:
Fingernails, including Johnny's, can be used for personal grooming. This includes tasks such as scratching an itch, brushing teeth, or even grooming others to reduce skin parasites like lice. In the JoJo's Bizarre Adventure series, Johnny uses his Spin-imbued nails for personal hygiene, such as brushing his teeth and grooming his hair.
Daily Tasks and Practical Applications:
Fingernails, including Johnny's, can assist in performing everyday tasks. They provide additional strength to the fingertips, making it easier to grip objects. Additionally, fingernails can be used for fine motor movements, such as separating pages in a book or picking up small items. In the series, Johnny uses his fingernails for mundane tasks like grating cheese and wrapping spaghetti around his fingers.
Protection and Self-Defense:
Fingernails offer a protective barrier at the tips of the fingers, helping to prevent viruses and bacteria from entering the body. In the context of the series, Johnny's fingernails serve as a unique form of self-defense, allowing him to shoot them as projectiles or use them to create wormholes to reposition himself or attack from unexpected angles.
Johnny's fingernails, therefore, serve multiple purposes beyond their use as projectiles. They have medical diagnostic value, assist in personal hygiene and daily tasks, and provide protection, all while being a central component of his combat abilities in the JoJo's Bizarre Adventure series.
