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, 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.
Girls with tattoos in novels are sometimes portrayed as having a mysterious allure. Their tattoos might be part of a backstory that adds depth to their character. Like in mystery novels, a tattoo on a girl could be a clue to a hidden past or a secret identity.
In some fanfictions, their first encounter is more comical. Aang might accidentally disrupt Katara's waterbending practice with his wild airbending stunts. Katara would be annoyed at first but then intrigued by this strange boy. They start off on a bit of a rocky note but quickly find common ground as they discover their shared love for their respective bending arts and their desire to make the world a better place. This kind of first encounter sets a tone of a relationship that will be full of growth and learning for both of them.
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.
They could also have a connection to his emotions. In fanfiction, perhaps when Harry is feeling angry, the tattoos might darken or become more prominent. When he is happy, they could shine brightly. This connection between his emotions and the tattoos could be a way for him to better understand himself and also for others around him to gauge his mood without him having to say a word. And the tattoos could potentially attract certain magical energies based on his emotional state, further affecting his magic.
In some cases, the anger could be a catalyst for a more romantic development. Aang expressing his strong emotions might make Katara realize the depth of his feelings for her. Or it could be the other way around, Katara's reaction to his anger could make Aang see her in a new light, leading to a shift in their relationship dynamic towards a more romantic one.
Say Jason has tattoos of animals like wolves or eagles. These could represent his sense of freedom and independence. Wolves are often associated with loyalty and a pack mentality, which might mean he values his close friends and family deeply. Eagles, on the other hand, symbolize a higher perspective and the ability to soar above difficulties, reflecting his ambitious and positive outlook on life.
It could also be that Katara was being overly critical of Aang's progress in learning new skills. Aang might feel frustrated and angry if Katara is constantly pointing out his flaws instead of being more encouraging, especially if he's already trying his best.
