It's possible that Jinora and Aang would face some sort of threat together. They would combine their skills to overcome it. Jinora's knowledge of the modern world and her own bending skills, along with Aang's experience and powerful bending, would make them a formidable team. They might have to fight against a new dark force that is threatening the balance of the four nations, and in the process, Jinora would come to respect Aang even more and vice versa.
In this fanfiction, they could go on an adventure together. Jinora is a very spiritual person, and Aang was also deeply connected to the spiritual world. They could explore some ancient spiritual sites. For example, they might visit the ruins of an old air temple that Aang used to know but Jinora has only heard about in stories. There, Aang could share his memories of the place, and Jinora could gain a deeper understanding of airbender history.
Jinora could become more confident. Meeting Aang, such an iconic and powerful bender, would inspire her. She might start to believe more in her own abilities and be more assertive in using her airbending skills.
Avatar Aang was a very important figure in the Avatar universe. One appropriate story could be about Jinora learning from Aang's teachings. For example, Jinora might study the way Aang brought balance to the world and use that knowledge to help solve problems in her own time. She could be inspired by Aang's courage in facing the Fire Nation and apply that to standing up against new threats in her community.
Well, Naruto could teach Aang some of his ninja techniques like the Shadow Clone Jutsu. And Aang could show Naruto how to control the air currents for faster travel. They might also team up to fight a common enemy, perhaps an evil spirit that threatens both their worlds.
If Korra meets Aang in fanfiction, they may have a deep conversation about the role of the Avatar. Aang could share his story of how he had to end the Hundred Years War and the toll it took on him. Korra could then talk about her struggles in the modern world with things like industrialization affecting the balance of the elements. This exchange would be really interesting as they compare and contrast their Avatar journeys.
Well, it could be that the Olympians introduce Aang to their own powers and magic. For example, Zeus could show him how to control lightning in a different way than Aang has seen before. Aang might also befriend some of the Olympians, like Hermes, and they could go on adventures together across different realms. This could lead to some interesting cultural exchanges between the two fictional universes.
Well, perhaps Korra could learn some of Aang's early airbending techniques. Since Aang was the first Avatar to master airbending in a long time, he might have some unique knowledge to share.
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.
In fanfiction, when Aang meets his grandchildren, it could be a very heartwarming moment. He might pass on his wisdom about airbending and the importance of balance in the world. Maybe he'll tell them stories of his adventures with his friends, like how they defeated the Fire Lord and brought peace to the four nations.
Perhaps in this fanfic, Naruto would be confused by the concept of the Avatar at first. But as he gets to know more about it, he realizes the similarities between his world and the Avatar world in terms of protecting people. He might also have some interesting interactions with the different tribes in the Avatar world, like the Fire Nation. And who knows, he could even find a way to use chakra to enhance bending abilities.
She might form a special bond with the dragons. In many fanfictions, characters who meet dragons often develop a deep connection, either through shared magic or mutual understanding.
