Well, if Aang joins the Fire Nation in fanfiction, it could lead to a total change in the power dynamics. He might try to reform the Fire Nation from within, using his Avatar powers for good in a different way. Maybe he'd start teaching the Fire Nation people about the other nations and promote peace and understanding among them.
The story would likely take a very different turn. Aang joining the Fire Nation could start with him being a sort of undercover agent, trying to figure out the secrets of the Fire Nation while pretending to be on their side. This could lead to some intense spy - like situations.
The story could focus on the character's struggle to fit into the strict hierarchy of the Fire Nation. As a prince, there would be high expectations, and they might have to deal with power - hungry nobles. They could also have to face the internal conflict of whether to follow the traditional path of Fire Nation aggression or strive for peace, like Zuko did in the original series.
One idea could be a crossover where Ben 10's Omnitrix malfunctions near Avatar Aang's world. Ben and Aang team up to face a new threat that is causing chaos in both their realms. Maybe some of Ben's alien forms have unexpected interactions with the bending abilities in the Avatar world.
In a fanfiction, the Avatar State of Aang could be used in a more creative way. For example, Aang accidentally enters the Avatar State during a cultural festival. His friends are initially worried, but then they realize that in this state, Aang can communicate with the spirits present at the festival in a unique way. He learns secrets about the spirits and their connection to the human world, which he then uses to strengthen the bond between the two realms when he's out of the Avatar State.
One great Aang fanfic could be one where he has to face an unexpected new threat in the Spirit World. It might explore his growth as the Avatar even further, showing his unique connection to the spirits and how he uses airbending in creative ways to overcome challenges.

Another fanfiction could explore the challenges they face during Katara's pregnancy. Since Aang is the Avatar, he has many responsibilities. There could be a conflict where he has to leave for an important mission, but he doesn't want to leave Katara alone. Katara, being strong - willed, tells him to go and fulfill his duties. In his absence, she discovers new water - bending techniques related to pregnancy and childbirth, which she plans to teach other women in their community later.
Avatar Aang's love story mainly involves Katara. They had a deep connection that grew over their adventures. Aang was initially just a friend to Katara, but as they faced challenges together, his feelings for her became more romantic. Eventually, they ended up together, and their love was a significant part of the Avatar story.
Most Avatar Aang graphic novels are suitable for a wide range of ages. The Avatar series generally has themes of friendship, courage, and self - discovery which are positive for all ages. However, it's always a good idea for parents to preview them for very young children.
