One idea could be a story where Percy uses his tattoos and piercings to express his rebellious side. Maybe he's in a world where such things are not fully accepted, and he has to fight against the norms.
One possible storyline could be that Naruto gets tattoos and piercings as a sign of his growth and independence. He might use them to show his newfound confidence and to distinguish himself from his previous self. For example, he could get a tattoo of the Nine - Tails on his arm to symbolize his connection with the powerful beast inside him.
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.
Sakura might be initially shocked. She has always known Naruto as the go - lucky ninja, and the tattoos and piercings would be a big change. She might scold him at first but then come to understand his reasons behind it.
They might make her more alluring to some characters. For instance, Ron could be initially shocked but then find her new look really attractive. It could add a new layer of tension or excitement to their relationship.
The piercings and tattoos can make him seem more rebellious. He might be seen as a non - conformist in the wizarding world which is often very traditional. This could lead to him being more outspoken and less afraid to challenge the status quo.
Perhaps Harry gets the piercings and tattoos as a form of rebellion against the traditional wizarding world. He then has to face the consequences and reactions from his friends and foes alike. It could lead to a story of self - discovery and acceptance within the magical community.
The Weasley family would have mixed reactions. Mrs. Weasley would be horrified and try to get Harry to remove them, thinking it was improper. Ginny might think it was cool and a sign of Harry's bravery to be different. The teachers at Hogwarts, like McGonagall, would probably be quite strict about it, seeing it as against the school's decorum. However, some of the more liberal - minded students might start to consider getting their own tattoos and piercings after seeing Harry's new look.
One possible storyline could be that Harry, after defeating Voldemort, decides to break free from the traditional wizarding world norms. He gets tattoos that represent his journey, like a lightning bolt for the scar on his forehead but in a more artistic way. For piercings, he might get an earring that has a magical charm on it. Another idea is that he gets tattoos as a form of protection spells, in a new and edgy way that the wizarding world has never seen before.
Another possibility is in a magical world - twist fanfic. Hermione discovers a magical piercing that gives her an extra boost of magical power. However, there are side - effects that she has to figure out how to deal with. Maybe it makes her spells a bit too powerful at first and she has to learn control.
