His distancing could also have an impact on the younger generation of ninjas. They look up to Naruto as a role model. If he distances himself, they might feel lost or confused, and some might even try to imitate his behavior in a wrong way, thinking that being alone is a sign of strength.
It could make his friends worry a great deal. For example, Sasuke might be concerned about Naruto's well - being and try to reach out to him. This could lead to a new dynamic in their relationship, with Sasuke being more proactive in their friendship.
In such a fanfiction, Naruto keeping to himself might make others initially find it hard to approach him. For example, his friends like Sasuke and Sakura might be a bit confused at first. Sasuke, who is also a bit of a loner in his own way, might not know how to deal with this new Naruto. Sakura, on the other hand, might try harder to break through his shell. This could lead to some strained relationships at the start, but as the story progresses, those who truly care about Naruto would try to understand him better and build deeper, more meaningful relationships with him.
If Naruto becomes unstable, Sasuke might be one of the first to be affected. Since they have a deep bond, Sasuke would feel responsible to bring Naruto back to his normal state. Sakura, too, would be worried. She might try to use her medical ninjutsu skills to see if there's a physical cause for Naruto's instability and then try to find a solution.
It can make characters like Kakashi feel a bit annoyed. Kakashi might think Kurenai is being too overbearing and it could disrupt the normal team dynamics if he also has a role in Naruto's development.
His friends would be worried. Sakura, for instance, might try to reach out to him and get him to open up. She could be constantly checking on him, bringing him food or just sitting with him in silence, hoping he'll start talking again.
The village elders would be in a state of panic. Naruto was seen as a symbol of hope and power for the village. His departure would mean a significant loss of strength and morale. The younger generation of ninja who looked up to Naruto would also be greatly affected. They might lose their motivation and start to question the values of the village.
His relationship with the village would also change. The villagers, who have come to rely on Naruto as a hero, would be confused and perhaps a bit scared. Some might feel betrayed that he has isolated himself. But there could also be those who understand his need for solitude and wait patiently for his return.
If Naruto has a physical disability like a broken arm that doesn't heal properly in fanfiction, his friends like Sasuke and Sakura would need to step in and help him more. Sasuke might be more protective, which could change their dynamic from a competitive one to a more collaborative one. Sakura could use her medical skills to try and find a way to heal him, which would bring them closer. His relationship with his teachers, like Kakashi, would also change as they'd have to adjust their training methods.
His friends would be hurt. They are used to the warm - hearted Naruto, and his coldness would make them feel rejected and confused. They might try to reach out to him but be constantly rebuffed.
It could make some characters more sympathetic towards him. For example, if Harry Potter were to find out in the fanfiction, he might start to see Snape in a different light, realizing that Snape has his own deep - seated problems. This could potentially lead to a more complex and nuanced relationship between them.
His relationship with his sensei, like Kakashi, could become more complex. Kakashi would feel guilty for not being able to protect Naruto from the experiments. And Naruto might start to question Kakashi's ability to keep him safe. This could lead to a strain in their relationship at first, but later they could grow closer as Kakashi helps Naruto recover from the trauma of the experiments.
