With the new characters introduced in the fanfic, if there are any, Naruto's lack of feeling could create an interesting dynamic. They might either be intrigued and want to help, or they might take advantage of his situation. And for Naruto, he would have to rely on others in a different way than before, which could either strengthen or strain his relationships depending on how others react.
His relationship with Sasuke would be greatly affected. Initially, Sasuke might not care much as he's so focused on his own path. But later, he might realize that Naruto was an important part of the team dynamic. Without Naruto, Sasuke may find that he misses the competition and the unique bond they had, which could lead to some self - reflection for him.
Well, it might make his relationships more complex. His friends could be both curious and a bit wary at first. For example, Sasuke might see him as even more of an oddity, which could either drive them further apart or make Sasuke more protective in a strange way. Sakura might be more motherly towards him, trying to take care of him because of his new features.
Well, if Naruto has no emotions in the fanfic, his relationships would become very strange. For example, his bond with Sasuke might not be as intense. Normally, their relationship is full of passion, rivalry, and a deep sense of friendship. But without emotions, Naruto might just see Sasuke as another ninja, not someone he has a strong emotional connection with. His interactions with Sakura would also be different. Instead of having his unrequited love for her, he'd be indifferent, which would change the whole dynamic of their trio.
His relationships with his friends would likely be severely strained. For instance, Sakura and Sasuke, who know Naruto as a kind - hearted person, would be horrified and confused. They might try to find a way to cure him or bring him back to his normal self.
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.
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.
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.
On the other hand, it could also strengthen his relationships with some characters. For instance, Kakashi, as his teacher, could be more proud of Naruto's growth in harnessing such a powerful force. And Naruto might also become a more respected figure among the younger ninja, who look up to him for his new - found power.
It could strengthen his bond with Sasuke. Since Naruto is getting more powerful, Sasuke might see him as a more worthy rival. This could lead to more intense and meaningful battles between them, but also a deeper understanding of each other.
Naruto's relationship with Sasuke could be really affected. Sasuke, having his own experiences with dark powers, might see Naruto in a new light. They could either become more competitive as they both struggle with different forms of dark power, or they could bond over their shared experiences of having something that sets them apart from others.
