One interesting fanfiction could be 'Naruto's Vision of Tomorrow'. In this story, Naruto starts having strange dreams that turn out to be visions of the future. It shows how he struggles to understand and change the events he foresees. Another great one is 'Future Sight: Naruto's New Path' where his ability to see the future makes him question his every decision in the present. And there's also 'Naruto and the Prophecy of the Future' which delves into how Naruto uses his new - found power to protect the village from threats that he anticipates.
There's also 'Harry Potter and the Future's Secrets'. Here, Harry starts seeing the future after a strange encounter in the Forbidden Forest. The story focuses on how he uses these future - seeing moments to protect his friends and outwit his enemies. It has some great plot twists and really delves into the relationships between the characters in the face of this new power.
One possibility could be that in the fanfiction, Kushina and Minato see Naruto becoming a great Hokage, respected far and wide. They might see him bringing peace to the village and forging strong alliances with other nations. This would make them extremely proud as they watch from whatever afterlife or special visionary state they are in.
One possible plot twist could be that Naruto sees a future where his friends turn against him. This would shatter his world as he values his friendships deeply. He might then struggle to figure out what went wrong in the future and try to prevent it in the present.
Seeing the future can create a sense of dread or hope, depending on what they see. If they see Camelot's downfall, they'll be filled with dread and work hard to prevent it. But if they see a prosperous future, they might become overconfident. Also, it can change their relationships. A character who was once carefree might become overly cautious if they see a dangerous future.
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.
In fanfic, the Naruto Orb's future - seeing ability can be portrayed in various ways. It could show hazy visions that are open to interpretation, like a blurry image of a battle with only a few recognizable elements. This makes the characters have to work hard to figure out what the vision means.
Power and responsibility is also a big theme. With the ability to see the future, Harry has a new form of power. Fanfictions may show him using this power wisely to save the wizarding world, or sometimes misusing it accidentally and facing the consequences. Additionally, the theme of self - discovery is common. As he sees the future, Harry learns more about himself, his potential, and his place in the grand scheme of things.
If Naruto sees the future, his relationship with Sasuke could change drastically. For example, if he sees Sasuke in danger in the future, he might become overly protective in the present, which could annoy Sasuke at first but also strengthen their bond in the long run.
