Another problem is that seeing the future doesn't always mean he can change it easily. He might see a friend die in the future, but despite his efforts, the events still unfold as he saw them. This could be really frustrating and might even make him doubt his ability. Also, if too many people find out about his ability, some might try to use him or control him for their own purposes.
Naruto might also face the challenge of misinterpreting what he sees. The future isn't always clear - cut. He could see a blurry vision of an event and misunderstand it. For instance, he might see a building on fire and think it's an attack, but in reality, it could be a planned demolition. This wrong interpretation could lead to him making wrong decisions and causing chaos instead of preventing problems.
If Naruto sees a future where he and Sakura are not as close as they are in the present, he might start to distance himself from her, thinking it's for the best. Or on the other hand, he could try to change the future by being more open and communicative with her. Also, with Sasuke, if he sees a future where Sasuke is in more danger than he thought, he would redouble his efforts to keep Sasuke safe and this would likely deepen their complex relationship.
One challenge could be dealing with over - emotional Pokemon. If he senses a Pokemon that is extremely angry or sad all the time, it might be draining for him. For instance, a Pokemon that has been abandoned and is full of sorrow might be hard for Naruto to be around without getting affected himself.
Naruto's future - seeing ability could completely shift the power balance in the story. He could use it to find out where all the powerful artifacts or secret techniques are hidden in the future. For instance, if he saw the location of the Sage of Six Paths' hidden power, he could get there first and gain that power. This would put him in a much stronger position than his opponents, and might even change the political situation in the ninja world as different villages would react to his new - found strength.
Naruto's ability to see the future in fanfiction can really mess with his relationships. He could see a future where his friends die because of his actions. This would make him question his place among them and might lead to him isolating himself. With his family, like if he has a future vision about his kids, he might be overly strict or try to control their lives too much to prevent the bad things he saw from happening. And with his teacher, like Kakashi, if he sees a future where Kakashi is in danger, he may act impulsively to save him, which could cause problems in their normal teacher - student dynamic.
This ability would make Naruto more cautious. Normally, he's quite impulsive, but seeing the future would force him to think before he acts. For example, if he sees that a rash decision leads to bad consequences in the future, he'll learn to hold back.
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.
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.
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.
Communication could be a big issue. Naruto has his own way of expressing himself in his world, with his ninja jargon and unique gestures. Kim, with her own lingo from her action - packed life, might find it hard to fully understand Naruto at times. Also, they both have their own sets of friends and allies. Naruto's friends like Sasuke and Sakura might not immediately get along with Kim's friends like Ron and Rufus. This could cause some tension in their married life.
In a married fanfiction, Naruto and Kurotsuchi may face challenges in terms of their busy schedules. Naruto, as Hokage, has a lot of responsibilities in Konoha, and Kurotsuchi also has important duties in Iwagakure. They might struggle to find time for each other. Also, there could be political pressures. Their marriage is not just a personal union but also a connection between two powerful villages. Political factions in both villages might try to use their marriage for their own gains, putting stress on their relationship.
