Well, in this fanfiction, Naruto might see himself as Hokage finally achieving all his dreams. He could see his friends and family thriving in a peaceful Konoha. Maybe he'd also see new generations of ninja being trained under his guidance.
Obviously Naruto himself is the most important as he's the one seeing the future. Sasuke would likely be there too, as he's Naruto's closest friend and rival. Sakura would probably also play a role, maybe as a skilled medical ninja in the future Naruto sees. Kakashi might also show up, perhaps as an elder guiding Naruto in his leadership role.
Naruto might meet his future children. He would be able to see what kind of people they are and what their dreams and aspirations are. It would be an emotional moment for him, seeing his family in the future.
Maybe Naruto sees himself as Hokage, with the village prosperous and peaceful. He could see his friends by his side, all having achieved their dreams too.
One common theme is self - discovery. When Naruto sees the future, he often has to re - evaluate who he is and what his purpose is. Another theme is sacrifice. He may see a future where he has to sacrifice something dear to him to save others. And of course, there's the theme of fate. He might struggle with whether the future he sees is set in stone or if he can change it.
Obviously, Naruto himself is the most affected as he has to deal with the knowledge of the future. But his friends like Sasuke, Sakura, and Kakashi would also be deeply affected. If Naruto saw a future where Sasuke was in trouble, he would do everything to change it, which would impact Sasuke's life. Sakura, being Naruto's teammate and also caring about Sasuke, would be involved in any plan Naruto made. And Kakashi, as their sensei, would be there to guide and support them through the changes Naruto tries to make based on his future vision.
One possible plotline could be Naruto seeing a future where his friends are in great danger and he has to find a way to change the course of events. For example, he might see that Sasuke is about to be captured by a powerful enemy, so he starts training extra hard to be able to rescue him.
Well, one possibility could be that Naruto has some sort of visionary ability where he can see snippets of the future during his past adventures. For example, he might see the final battle against Kaguya while he's still on a mission with his team as a genin. This could change his approach to training and how he interacts with his friends, as he tries to prepare them for what's to come.
One possibility is that it could show Draco having a change of heart. Maybe he realizes the error of his ways and sees a future where he and Hermione work together for the greater good of the wizarding world. They could be fighting against dark forces side by side, with Hermione's intelligence and Draco's knowledge of the inner workings of some dark families proving useful.
In such fanfictions, the relationship between Naruto and Kyuubi can be developed in various ways. For example, the Kyuubi could start teaching Naruto about his heritage in a more motherly way, like sharing stories of the Uzumaki clan. Naruto, on the other hand, could show his loyalty and love towards the Kyuubi as he would to a mother. This could also impact his relationships with other characters. His friends might be initially confused but later come to understand and support this new relationship of Naruto's.
