His relationships would become very different. With his friends, they would feel like they've lost him. They would constantly be trying to find a way to bring back his emotions. His relationship with his mentor, like Iruka or Kakashi, would also change. Iruka, who has always seen Naruto as a warm - hearted boy, would be heartbroken. And Kakashi would be more determined than ever to find a solution, but the emotionless Naruto would not understand their concerns as he no longer has the ability to empathize.
Well, it would be a huge blow to his friendships. Naruto's friends are drawn to his big heart and strong emotions. An emotionless Naruto would not respond in the same warm way. He might not share in their joys or sorrows. Sakura, for instance, would miss his determination and the way he used to encourage her. His friends would have to work hard to reach out to him, but they may also start to drift apart because the emotional connection is no longer there.
His relationships take a big hit. His friends like Sakura and Shikamaru would find it hard to connect with him. Sakura, who's used to Naruto's warm and often goofy self, would be at a loss. Naruto's lack of emotion means he won't show the same level of care or enthusiasm towards her. With Shikamaru, their conversations would be very different. Shikamaru is used to Naruto's emotional outbursts and quick decisions based on feelings. Now, Naruto would be more reserved and logical, which could strain their friendship.
Well, perhaps a plot where Orochimaru manages to get his hands on Naruto and uses some dark experiments to turn him into an emotionless tool. Naruto then starts to carry out Orochimaru's bidding, like stealing valuable scrolls from other villages. Or maybe in a parallel universe, the Akatsuki capture Naruto and brainwash him into an emotionless tool to use against the Hidden Leaf, and his friends have to find a way to break the spell.
It would have a huge negative impact. Naruto's friends have come to rely on his emotional support and his ability to inspire them. Without his emotions, he might not show the same enthusiasm in helping them. His friendship with Kakashi would also change as Kakashi has guided Naruto in part based on his emotions and his will to protect his friends. Naruto might seem distant and unresponsive, causing his friends to feel rejected.
Well, if Naruto is emotionless in this fanfic, his relationship with Sasuke would be drastically different. There would be no intense rivalry based on emotions like in the original Naruto. In the Bleach world, his relationship with Ichigo might be more of a power - centered one. Since Naruto doesn't feel emotions, he might only see Ichigo as a means to an end, like a source of power or a tool to achieve his goals in this new crossover world.
In Naruto fanfiction, battle scars can have different effects on character relationships. Sometimes, a scar can be a source of pity or admiration. If a character has a visible and prominent scar, some might pity them for what they've been through, while others might admire their strength in surviving the incident that caused the scar. This can lead to new friendships or even romantic interests. Also, scars from battles against a common enemy can bring characters closer together as they share a common memory of struggle.
In Naruto fanfiction with the Kaiju bloodline, it can have a huge impact on relationships. If a character has this bloodline, those who are power - hungry might try to use them or manipulate them for their own gain. This can lead to a lot of mistrust. However, among true friends, it could be a source of admiration. They might see the unique abilities as something that can protect the village and be proud of the character. Also, in romantic relationships, the Kaiju bloodline could be both a draw and a concern. A partner might be attracted to the power but also worried about the danger it brings.
With his Anbu comrades, Naruto's emotionless state would create a sense of distance. They would find it hard to trust someone who doesn't show any emotions. However, some might respect his cold - efficient way of handling missions. In the long run, if he doesn't change, he might be isolated within the Anbu ranks, as relationships in the Anbu are also based on some level of mutual understanding and emotional connection.
In Naruto fanfiction, the mind control bloodline can have a huge impact on character relationships. If a ninja uses the power to make another ninja do their bidding, it can lead to mistrust among their comrades. They might start to question who they can really trust. Moreover, if a character is mind - controlled into betraying their clan, they will face a lot of difficulty in being accepted back. Their family and friends will have to grapple with the fact that the betrayal wasn't entirely their fault, but still, there will be a sense of unease and a need to rebuild the relationship.
His relationship with Sasuke would become very strained. Usually, they have a complex bond based on rivalry and friendship, but as an emotionless killer, Naruto would see Sasuke more as a target or an obstacle. He wouldn't care about Sasuke's own goals or feelings.
