A really interesting fanfic I read had Aang and Katara having a disagreement over how to deal with a new threat. Aang believes in a more peaceful approach, while Katara thinks they need to be more forceful. This creates tension between them, but as they work through it, they realize that they need to combine both their ideas. It's a story that really delves into their characters and how they complement each other.
The 'power - couple' trope is also quite common. Aang, as the Avatar, and Katara, a powerful waterbender, are seen as a formidable duo. Fanfics often explore how they use their combined powers to defeat enemies and save the world. Also, the 'misunderstanding' trope where they have a fight because of a miscommunication but then make up is popular. It adds drama and emotion to their relationship.
In Avatar: The Last Airbender, Aang and Katara's love story is a beautiful journey. Initially, they had different goals but were united by the need to save the world. Aang, being the Avatar, was a bit naive at first, and Katara was more mature. However, as time passed, Aang learned from Katara, and she was inspired by his determination. Their shared experiences, like fighting the Fire Nation, exploring different cultures, and facing personal losses, all contributed to their love. Katara's motherly side towards Aang also evolved into a romantic love as they both grew up, and in the end, they became a couple.
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.
One great Aang fanfic is 'Aang's New Adventure'. It takes place right after the end of the series. In this fanfic, Aang has to deal with some leftover Fire Nation rebels who don't want to accept the new peace. It's really exciting as it shows Aang using his bending skills in new and creative ways to bring about peace once again.
I really like 'Zuko and Katara: A New Bond'. In this fanfic, their bond forms as they face a new common enemy. It beautifully portrays their growth as individuals and as a duo. The author does an excellent job of writing their dialogues, making them feel very true to their characters in the series.
I liked 'Katara and Zuko's New Beginnings'. It's a fanfic that takes place after the end of the series. It focuses on how they navigate the new world order together. There are some really sweet interactions between them as they try to build a new life for themselves and their friends. It also has some great action scenes where they use their bending abilities side by side.
Another aspect is the relationships in the fanfic. Aang has important relationships with Katara, Sokka, Toph, and others. If a fanfic can develop these relationships in new and interesting ways, it's great. For instance, a story where Aang and Katara have a misunderstanding that they need to work through, which could test their relationship and show their individual growth as characters.
Some fanfictions in this category could focus on Aang's relationships. For example, a story about how Aang helps Toph deal with a family issue that she's been hiding. This would show a different side of Aang, not just as the Avatar but as a true friend. It could also explore how their friendship deepens through this experience.
In the 'Avatar: The Last Airbender' series, there are no real love stories between Azula and Aang. Azula is a complex antagonist, while Aang is the heroic Avatar. Their relationship is mainly one of opposition, with Azula constantly trying to thwart Aang's mission to save the world.
