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.

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.

His relationship with Katara would be very different. He might be able to approach her in a more confident way, knowing what they've been through in the future. He could also avoid some of the misunderstandings that happened between them in the original timeline.

Dean Winchester is often a common character. Since he has a strong bond with Castiel, he might be involved in the time - travel events either directly or through Castiel's actions in the past that affect him in the present.

He could meet his future self. It would be an interesting encounter as he could learn from his future experiences and wisdom. Or he might meet people who have studied his past adventures and see himself through their eyes.

Katara could be one of the main characters. She might play a role in helping Aang through the process of opening his chakras, either with her healing abilities or just by being there to support him emotionally.

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.
