In some fanfiction, Harry's tattoos might be related to his family history. Maybe they represent the Gryffindor heritage in a new and unique way. For instance, they could be a map of all the Gryffindor secrets passed down through generations. Or perhaps his tattoos are a connection to a long - lost relative who was a great tattoo artist in the wizarding world. This relative might have used magic in the tattoos that Harry has to discover and use to his advantage.
One interesting fanfiction could be where Harry's tattoos have magical properties. For example, they might glow when he's near danger or change shape depending on his mood. Another could be a story where the tattoos are a form of secret code among a group he's part of, and he has to decipher them to unlock an ancient magic. There might also be a fanfic where his tattoos are a result of a powerful spell gone wrong, and he has to figure out how to reverse it while dealing with the strange looks from others.
One interesting story could be Harry getting a tattoo that represents his connection to his parents. Maybe a stag for his father and a lily for his mother. It could be a way for him to carry their memory with him in a more permanent and visible way.
There could be a fanfiction where Naruto gets tattoos as a form of rebellion. Tired of being the 'good boy' of the village, he decides to get tattoos that are frowned upon by the elders. These tattoos might have a deeper meaning related to his past, like markings that represent his parents in some way. This causes a stir in the village, but Naruto stands by his decision, which also helps him grow into a more independent and self - assured person.
One interesting story could be where Hermione's tattoos hold magical powers. For example, she has a tattoo that glows when dark magic is near, helping her and her friends detect danger. The piercings could be enchanted too, like a nose piercing that allows her to understand ancient spells when she whispers through it.
On the other hand, some characters could be a bit intimidated by the tattoos. For instance, the more traditional wizards in the Ministry of Magic might see them as something strange or even a sign of dark magic, which could cause some strain in Harry's relationships with them.
In some fanfictions, Percy's tattoos could be symbols of his heroic deeds. For example, he might have a tattoo of a trident to represent his connection to the sea. It could be a mark given by a powerful sea deity after a great victory. Another possibility is that his tattoos are a form of map, perhaps leading to a hidden treasure or a secret underwater kingdom that only he can unlock.
Another interesting plot could be that her tattoos are a form of self - expression against the strict rules of the wizarding world. In a world where everyone is expected to conform, her tattoos make her stand out. They could also be a connection to a secret society or group within Hogwarts that values individuality and rebels against the status quo. For instance, a group of students with similar tattoos who meet in a hidden part of the castle to practice unorthodox magic.
