What adventures might the Gaang have during their travels to the Air Temple of the past in fanfiction?

They could meet past Air Nomads. These could be great benders or spiritual leaders who can offer wisdom and advice.

In this fanfiction, they might discover long - lost Air Nomad artifacts at the Southern Air Temple. These artifacts could hold the key to new airbending techniques.

The main characters are surely the members of the gaang, which include Aang, Katara, Sokka, and maybe Toph. Aang is the most important as he is an Air Nomad and the Southern Air Temple is his heritage.

They might have an adventure where they stumble upon a hidden magical grove. In this grove, there are plants with unique magical properties that they've never seen before. They could spend time studying these plants and perhaps even discover a new potion ingredient.

Goten could meet the younger versions of his friends like Krillin or Yamcha. They might be a bit skeptical of him at first. He could also run into Master Roshi, who would probably be interested in Goten's abilities and might try to teach him some old - school techniques. And there's a chance he meets Bulma, who could be intrigued by his futuristic knowledge and might even try to get some tech ideas from him.

Naruto would meet his younger self. This would be a really strange situation. He could also meet all the important shinobi from the past. For example, the First and Second Hokage. He might have a chance to learn from them directly, instead of just hearing about them in stories. Additionally, he could meet some of the characters who were only mentioned in passing in the original story but had a big influence in the past.

Another possibility is that he gets involved in the early days of the Akatsuki. He might try to change the course of the organization, perhaps by convincing some of its members to abandon their more evil plans. Since he's already a retired and experienced ninja, he has a different perspective on things compared to when he was younger.

Well, they might gain a deeper understanding of Zuko. They could see all the pain and struggle he went through, which might lead to them being more empathetic towards him. Maybe it would even change their relationship dynamics, making them more accepting of Zuko in the group.

Obviously, the main characters would be the Gaang, which includes Aang, Katara, Sokka, Toph, and Zuko himself since he's the one being kidnapped.

Well, in this fanfiction's training trip, Naruto may come across different clans with their own exclusive fighting styles. He could engage in friendly sparring matches with their members, which would not only enhance his combat abilities but also his understanding of different cultures within the ninja world. He might also find some ancient artifacts that hold great power and have to figure out how to use them properly without being corrupted by their power.
