Some interesting ideas for this fanfiction could involve a scenario where the spells in Harry Potter and the bending in the Last Airbender are somehow related. Maybe certain spells can unlock or enhance bending abilities. For instance, the Wingardium Leviosa spell could be linked to airbending, allowing a character with both magic and potential airbending skills to levitate in a more powerful and controlled way. You could also create a story where the Ministry of Magic tries to regulate bending, thinking it's a new and dangerous form of magic. And a story where Ron Weasley, after a strange encounter, starts to show earthbending abilities and has to adapt to this new power while still being part of the wizarding world.
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 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 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.
One common theme is the power of friendship. In both 'Harry Potter' and 'The Last Airbender', the main characters rely on their friends. So in fanfiction, this is often explored further. Another is the battle between good and evil.
One idea could be exploring an alternate timeline where Aang fails to defeat the Fire Lord. Maybe in this timeline, the Fire Nation completely takes over the world, and the remaining benders have to go into hiding and plan a long - term resistance. Another plot could be focusing on a new airbender discovered long after Aang's time, and their journey to master airbending without the guidance Aang had.
One common theme is the clash of different cultures. For example, the wizarding culture in Harry Potter and the diverse cultures in Avatar. Another theme is the discovery of new powers. Characters from one universe might discover the abilities of the other universe, like a Hogwarts student learning bending.
A fanfiction could explore what would happen if the magic from the Harry Potter universe was somehow combined with the powers of the Last Witch Hunter. For example, the Last Witch Hunter could gain the ability to use spells like Harry Potter, or Harry could get some of the unique skills of the Witch Hunter. This would lead to a whole new set of adventures and challenges for them both.
In another idea, Harry's last kiss could be with a time - traveling version of his mother. This would be a very emotional and complex situation. The kiss might be a way for him to finally say goodbye to his mother in a more personal way than just seeing her in the Pensieve. It could also bring about some unforeseen consequences in the time - space continuum of the wizarding world.
One of the main things is the opportunity for new and unique storylines. The original stories of Harry Potter and Avatar are well - known, but in fanfictions, authors can create whole new adventures. They can explore what would happen if the Death Eaters attacked the Water Tribe, or if the Firebenders tried to take over Hogwarts. It allows for a great deal of creativity and exploration of different themes and ideas.
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.
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.
