Well, if Naruto travels to the future in fanfiction, he may encounter his descendants or versions of his friends that have changed a great deal. Maybe he would find that Konoha has evolved into a super - high - tech ninja village. He would need to learn about the new political situations, new enemies, and new ways of being a ninja. For example, he might have to deal with ninjas who can control artificial intelligence as their weapons. He would be confused at first but then use his determination and strong will to figure things out.
In such a fanfiction, Naruto might try to prevent some of the tragedies that occurred in the past. For example, he could stop the Uchiha massacre. He would use his knowledge from the future to change things. Maybe he'd also be able to save some characters who died early in the original story, like Jiraiya. And he could potentially have a huge impact on the relationships between different clans, as he'd know about future conflicts.
He might be shocked by the advanced technology. There could be new forms of ninjutsu or combat styles. He would also have to adapt to a different social structure.
Well, if Naruto saw the future in fanfiction, he might discover some dark secrets about his friends or family. This could make him question his relationships. For example, he might find out that a friend will turn against Konoha in the future. He'd then be in a dilemma of whether to trust his friend or take preventive measures.
He might get some insights into different possible futures for himself and his friends. It could be both inspiring and a bit disconcerting as he sees versions of events that may or may not come to pass.
He might be really confused at first. The modern world has so many strange things for him like cars and skyscrapers. He'd probably try to use his ninja skills in unexpected ways, like using his shadow clone jutsu to do multiple tasks at once, like shopping and exploring the city simultaneously.
Well, he might be shocked by the advanced technology. Maybe he'll see flying cars and buildings that touch the sky. He could also encounter new forms of the Force that he doesn't understand. And perhaps he'll meet descendants of his friends or foes, which would be really interesting.
In this fanfiction, Aang might encounter advanced bending techniques. Since he's traveling to the future, he could see how bending has evolved over time. Maybe there are new forms of bending that combine different elements in ways he never thought possible.
Sasuke traveling to the future in the fanfiction would be full of possibilities. He could find that the traditional ninja clans have evolved into something completely different. For example, the Uchiha clan may have developed new and unique powers that are a combination of their Sharingan heritage and future technology. He may also meet versions of himself from different timelines, which would create a very complex and mind - boggling situation as he tries to figure out his place in this new future.
If Naruto was watching future fanfiction, he'd probably have a mixed reaction. On one hand, he might be amused by the creative ideas. For example, seeing himself in outlandish adventures or having new jutsu that are really far - fetched. On the other hand, he could be a bit offended if the fanfiction portrays him in a negative light, like being a bad leader or something. But overall, it would be a very strange experience for him to see how others imagine his future.
They might be shocked. For example, Naruto himself, if he reads about future threats to the village in the fanfiction, he would probably start preparing immediately to protect his friends and the Hidden Leaf. It could change their present actions as they try to avoid bad futures or work towards good ones.
