In the last airbender fanfiction, there are various interesting concepts. One is the exploration of the spiritual side of bending in more depth. Maybe a fanfiction could show how the connection to the spirits affects the benders' powers on a day - to - day basis. Another concept could be the creation of new tribes or groups within the four nations. For instance, a group of waterbenders who have a unique way of using their powers that is different from the Northern and Southern Water Tribes. And, there could be fanfictions that focus on the political intrigue within the nations, like secret alliances and power struggles that we didn't see much in the original show.
One interesting concept could be new bending techniques. Maybe the fanfic explores an advanced form of waterbending that combines with spirit energy. Another concept might be the introduction of new characters who have unique relationships with the existing ones. For example, a new airbender who has a different philosophy about peace compared to Aang.
There are fanfictions that explore the lives of the minor characters. For instance, a story about the Kyoshi Warriors. It could be about how they trained, their daily lives, and how they interacted with the main characters like Sokka and Katara. Also, some fanfictions might center around the idea of a new bending art that combines different elements in a unique way.
One interesting concept could be an Airbender who was raised in a non - Air Nomad culture and has to rediscover their airbending roots. This would bring in a lot of internal conflict as they balance the values of their adopted culture with their native airbending heritage.
One interesting storyline is Aang's journey to master all four elements. He starts as a young Airbender and has to learn waterbending from Katara in the Southern Water Tribe. This not only helps him grow as a bender but also deepens his relationship with Katara. Another great one is Zuko's redemption arc. He goes from being a banished prince obsessed with capturing the Avatar to realizing the wrongs of the Fire Nation and eventually joining the Avatar to bring balance.
One interesting plotline could be a time - travel one where the main character, say Aang, goes back in time and has to deal with different characters in a new way, leading to a harem - like situation. For example, he might have to earn the trust and friendship of characters earlier than in the original story, and these relationships develop into something more complex over time.
One idea could be a crossover with the Harry Potter universe. The Avatar characters could attend Hogwarts and learn magic while also using their bending abilities. For example, Aang could use his airbending to enhance his flying on a broomstick. Another idea is a crossover with the Star Wars galaxy. The benders could be like Jedis, using the Force which is somewhat similar to bending the elements. They could help the Rebels in their fight against the Empire.
One interesting crossover could be a scenario where Naruto characters learn airbending techniques. Imagine Naruto trying to master the art of airbending, using his own chakra control skills to adapt to this new form of power. It would be a really cool combination of the two universes.
One idea could be a crossover with 'Harry Potter'. The Avatar could visit Hogwarts and learn about magic there. Maybe Aang could teach the students about bending while learning about spells himself. Another idea is a crossover with 'Lord of the Rings'. The airbenders could fly over Middle - earth and help in the fight against Sauron. They could use their bending skills to create distractions or help in battles.
Well, you could write a fanfiction where the Sorting Hat in Harry Potter is actually an ancient airbending relic. In the story, it could have the power to sense not just a student's Hogwarts house potential, but also their potential as a bender in the Last Airbender world. Also, imagine a plot where Dumbledore was once an acquaintance of an old Avatar and learned some airbending wisdom from him, which he then uses to guide Harry in his fight against evil. And a third idea might be a fanfic in which the Marauders were secretly training in bending arts during their Hogwarts days.
One interesting concept could be alternate endings. For example, what if Joel made a different choice at the end of the game? Fanfiction might explore a scenario where he lets the doctors operate on Ellie, and how that would change the fate of both characters and the world they live in.
