They would probably be shocked. For example, Naruto might be amazed to see how the village develops further. He could be excited to see new generations of ninjas and the peace that his efforts have led to in the future. Sasuke might be more reserved in his reaction, but he would also be interested in seeing if his own actions had a long - term impact on the ninja world.
Kristoff, in the future he watches, might become more refined and diplomatic. If he sees himself as part of the Arendelle court in the future, he would have to learn to interact with nobles and other royalty. He would start to pick up on social graces and political savvy, which would gradually change his rough - around - the - edges personality in the present as he prepares for that future role.
Naruto might become more determined in his present decisions. If he sees a great future in the fanfiction, he'll strive even harder to achieve that. He'll think that his current actions are even more crucial for that positive future. For example, he might be more eager to train the next generation of ninjas.
The relationship between Ladybug and Chat Noir could deepen into a more mature partnership. They might start to rely on each other not just as superheroes but also as friends who truly understand each other's strengths and weaknesses. Marinette could also become more confident in her relationship with Adrien, and their romantic feelings might become more open in the future setting of the fanfiction.
They might get a glimpse of different possible futures for themselves. It could be a really strange experience for them. For example, if a character from a fantasy world reads a fanfiction about their future, they might see new plotlines that they never expected, like different relationships or new adventures.
Some characters might be shocked. For example, if a heroic character sees a fanfiction where they turn evil in the future, they would be very surprised. They might start to question their own actions and whether there are any signs that could lead to such a change.
Well, the Jedi are obviously main characters. It could be well - known Jedi like Obi - Wan Kenobi or Yoda. They would be the ones using their connection to the Force to watch the 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.
Well, Naruto is most likely still one of the main characters. Since it's a Naruto - related fanfiction, he would be central to the story. Sasuke might also be a main character as their relationship has always been a crucial part of the Naruto universe. Sakura could also be there, as she has been an important part of the original story and would likely play a role in this future - oriented fanfiction.
Naruto's children would likely be main characters. They would inherit his strength and determination. Also, the students of the new generation of ninja academies could play important roles as they strive to make their mark in a world shaped by Naruto and his peers.
