Sokka could be one of the main characters. He might be the one helping Aang with his schoolwork, especially in subjects like history or math, using his own knowledge and quick thinking.
Well, it could be about Aang making new friends at school. Maybe he uses his airbending skills in some unique ways during gym class or recess, like creating a gentle breeze to cool down his classmates on a hot day.
He might start by observing. Aang is a curious person, so he'd likely watch how people live, how they interact with technology. He may also try to find other benders to learn about any new developments in bending. And he'd probably use his kind heart to make friends easily in this new future environment.
Sokka would also be a common character. His strategic mind could be very useful in a different time period. He might be the one who figures out how to deal with the new situations they encounter while in the past. For instance, if they need to outwit an enemy in a historical battle, Sokka would be the one to come up with a plan.
Aang could be friends with Neville. Neville is often underestimated but has a lot of courage, just like Aang. They could bond over their shared experiences of being different. Also, Luna Lovegood might be interested in Aang's unique abilities and his different world view, so she could be a potential friend too.
Well, in this fanfiction, Aang might bring his airbending skills to Hogwarts. He could use his bending to create interesting effects during Quidditch matches, like using air currents to speed up the broomsticks. He may also interact with the Hogwarts students in unique ways, perhaps teaching them a bit about his culture from the Avatar world.
Well, he could encounter advanced technology that he has never seen before. It would be interesting to see how he, as a traditional bender, reacts to things like flying machines or high - tech communication devices. Also, he might meet people who have different views on the role of the Avatar in this new future world.
Maybe in the fanfiction, Aang goes back in time and meets his past self. He then has to guide his younger self without disrupting the timeline too much. This could lead to some really cool moments of self - discovery for Aang, as he sees himself from an outside perspective and realizes how much he has grown.
Another theme is self - discovery. In high school, Aang has to figure out who he is in this new environment, which is different from his previous world. This includes exploring his powers further and how they fit in with his new life.
Well, he could prevent some of the great disasters that happened in his world. Maybe he could stop the Fire Nation's initial attacks and change the whole course of the war. He might also be able to save some important characters who died in the original timeline.
