Some characters might be afraid of the wasp hive and avoid Naruto because of it. This could cause a bit of a rift in his friendships at first.
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 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.
When Naruto snaps at Konoha in fanfiction, it has a complex impact on his relationships. With his closest friends like Sakura, she might initially be confused and try to talk some sense into him. But if Naruto is resolute, it could create a divide. His relationship with the village leaders would turn sour, as they see him as a threat to the village's stability. However, some outcast ninja in Konoha might see Naruto as a kindred spirit and side with him, which could also lead to new alliances and friendships.
Well, when Naruto has multiple affinities in fanfiction, it really shakes up his relationships. Imagine if he has lightning affinity. Lightning - style ninjas may see him as a kindred spirit and form closer bonds with him. On the other hand, some characters who are used to Naruto having a more limited set of abilities may feel threatened. This can lead to some characters trying to undermine him, while others will be drawn to his new - found potential and seek to be his friend or mentor.
If Naruto can shapeshift, it might make some characters more distrustful at first. They would be unsure if it's really him or an imposter. For example, Sakura might be more cautious around him until she can confirm it's the real Naruto.
Well, in such fanfictions, Naruto's stupidity might make some characters more protective of him. For example, Sasuke could be more annoyed at first but gradually become more concerned as he realizes Naruto's good heart beneath the 'stupid' actions. And Sakura might scold him more often, but still care for him in a sisterly way. It can create some interesting dynamics in their friendships.
It could make some characters more respectful. For example, those who previously underestimated him might see his new ability as a sign of great power and start to treat him differently.
His relationship with clan members might become strained. They may side with their clan heads, causing Naruto to be at odds with them even if he was friends with some of them before. For instance, if a clan member is loyal to their head's views that Naruto opposes.
It could improve his relationship with Sasuke. Since Chidori was Sasuke's signature move for a long time, Naruto learning it might show Sasuke that Naruto respects his skills and is willing to incorporate them into his own fighting style. This could lead to a more positive and equal relationship between them. Also, Kakashi might see Naruto in a new light. He trained Sasuke in Chidori, and seeing Naruto master it too could make him realize Naruto's determination and growth even more.
It could also affect his friendships. Some friends might try to convince him to let go of his hatred, which could cause friction. On the other hand, some friends might support his stance, which could lead to them being at odds with the clan. For example, Sasuke, who has his own issues with his clan, might react in different ways depending on Naruto's situation.
