The black chakra could make other characters view Naruto with suspicion. His friends might be worried that this new power is corrupting him, which could strain their relationships. For instance, Sasuke might see it as a sign that Naruto is becoming more like the enemies they've fought.
Some characters might be afraid of Naruto if he has black chakra. For example, his friends like Sakura and Kakashi could be initially cautious around him.

Sakura might worry that the black chakra could harm Naruto himself, while Kakashi would be on high alert to make sure Naruto doesn't lose control.
Naruto's chakra mastery affects his relationships in multiple ways. In his friendship with Shikamaru, his chakra control allows him to keep up with Shikamaru's strategic plans during battles.

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.
Naruto's dense chakra could make his friends either jealous or in awe. If he can do things with his chakra that others can't, some might envy his power.

For example, Sasuke might see Naruto's dense chakra as a new challenge to keep up with, which could improve their friendly rivalry.
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.
It could strain his relationships. His friends might be initially scared of him. For example, Sakura might be hesitant to be near him, fearing that the dark chakra could make him lose control and hurt her.
His friends would be extremely worried. Sakura, for instance, would likely try to use her medical skills to help him and also try to figure out why he's doing it. She might be angry at first for him harming himself but then become very concerned. His relationship with Sasuke could also change. Sasuke might see Naruto's self - harm as a sign of weakness or, on the other hand, it could make him more empathetic towards Naruto as he has his own inner demons.
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.
