Well, in fanfiction, Aang's tattoos often play a big role. They can be a way to show his connection to the Air Nomad culture that was almost lost. It could also be a visual cue for his development as a more powerful and wise Avatar. Maybe in some fanfics, the way he gets his tattoos is different from the original story, which adds an interesting twist to his character arc.
Another plotline could involve an enemy trying to stop Aang from getting his tattoos. They fear that once he has them, he'll become too powerful. So, they send various obstacles in his path, like attacking the place where he's getting the tattoos or trying to corrupt the tattoo artist.
One interesting story could be about the spiritual journey Aang undertakes while getting his tattoos. Maybe he has visions during the process that give him insights into his future role as the Avatar. For example, he might see flashes of the challenges he'll face in bringing balance to the world.
In some fanfiction, Aang's tattoos might be depicted as glowing with a special power when he reaches a new level of understanding or connection to the Avatar state.
Well, he might get a tattoo of the Rasengan on his palm. Since the Rasengan is one of his signature moves, it would be a cool and meaningful tattoo. He could also have a tattoo of his master, Jiraiya's, book mark. It would be a way to honor his mentor. Additionally, a tattoo of the chakra pathways on his body could be an interesting concept, highlighting his ninja powers.
The tattoos could signify his rebellious nature. As for the rituals, they might be a way to connect with his ancestors. For instance, a tattoo of a constellation could be related to a family ritual of stargazing and drawing power from the stars.
In a fanfiction of Aang and Toph getting married, it could be really sweet. Maybe it would start with Aang nervously proposing to Toph in their favorite place in the Avatar world. Toph would probably be her tough - yet secretly soft - self and accept in her own unique way. Their wedding could be a grand affair with all their friends from different nations coming together. It would be a blend of different cultures, like air nomad traditions of peaceful chants during the ceremony and earth kingdom's strong and stable architecture for the venue.
His tattoos might make him seem more mysterious to his friends. They could be intrigued by the new addition to his appearance and want to know the stories behind them. This could lead to deeper conversations and strengthen their bonds.
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.
The vision could be a sign of his future path or a revelation about the world he's in. It might hint at new powers or challenges he'll face.
In fanfic, tattoos can have magical properties. A tattoo of a magical object, say the Elder Wand, might give the wearer some power related to the object. It could also be a form of protection. If a character has a tattoo of a powerful charm, it might protect them from certain dark magic. Moreover, tattoos can be used to tell a character's backstory. A character with a tattoo of a certain place in the wizarding world might have had an important experience there.
