One possible meaning could be a sign of his individuality. In the world of fanfiction, Peter might use tattoos to set himself apart from the normal, expected image of Spider - Man. It could also represent a new phase in his life, perhaps a more rebellious or self - discovery phase.
Well, one possible tattoo design could be the Uzumaki clan symbol. It would represent Naruto's connection to his family heritage. Since he grew up without his parents, having this tattoo could be a way of carrying their legacy with him. Another could be a tattoo of his Nine - Tails form. It might symbolize his power and how he has tamed the beast within. And a third option could be a tattoo of his friends' symbols combined, like Sasuke's Sharingan and Sakura's forehead protector mark, to show his bond with them.
In some fanfiction, Peter Parker having tattoos can add an edgy or rebellious aspect to his image. It might make him seem more complex and less of the traditional 'clean - cut' superhero. However, in other interpretations, it could be seen as a way to show his growth or a connection to a different side of his life, like his time in the streets or a new group he's associated with.
Perhaps in the fanfiction, Peter Parker was exposed to a magical artifact that cursed him with vampiric features, such as fangs. Or, it could be that he made a deal with a dark entity in order to gain more power to fight his enemies, and part of the deal was getting fangs. This would add a moral dilemma to his character as he has to deal with the consequences of this deal.
One possible meaning could be a sign of his newfound power. For example, if he has a tattoo that glows when he uses a certain jutsu, it represents his connection to that power.
One possible plotline could be that Peter is poisoned by one of his enemies, like the Green Goblin. He then has to struggle to find an antidote while still trying to keep his identity a secret. Maybe he uses his scientific knowledge to analyze the poison and find a cure, all while fighting off the effects of the poison.
Well, one reason could be that he's on a secret mission for S.H.I.E.L.D. that requires him to go undercover and cut off all contact. Maybe he's investigating a new super - villain threat that's too dangerous to let anyone know about.
A plotline could involve Peter having a major falling out with his loved ones. For example, if he feels betrayed by his friends or Aunt May, he could turn evil. He might then use his knowledge of the superhero community to target other heroes and villains alike, causing chaos in the city. Another idea is that an outside force, like an alien symbiote or a powerful magic, could influence his mind and make him evil, leading to a series of events where he tries to reshape the world according to his now - twisted views.
A possible reason could be for self - expression. Naruto is a very expressive character, and tattoos could be another way for him to show who he is. It could also be a way to distinguish himself from other ninjas.
In this fanfiction, perhaps Peter Parker is a huge dragon fan from a young age. One day, he somehow gets transported to a world full of dragons. There, he uses his intelligence and Spider - Man - like skills to survive. He might learn how to communicate with the dragons and ends up befriending one. This dragon could then help him get back to his own world, but not before he has to face some challenges in the dragon world, like saving the dragon eggs from poachers.
A third storyline could be Peter on a date with MJ. All of a sudden, he has an asthma attack. This could add a layer of vulnerability to their relationship. MJ could be shown as being very caring and helpful, and it could also be a moment where Peter has to be honest about his health condition to someone he cares about deeply.
