For Naruto and Sakura, their relationship would transform significantly. Naruto joining Akatsuki would be a huge shock to Sakura. At first, she might feel betrayed, but as she realizes Naruto's motives, she would start to support him in secret. This would lead to a more clandestine and deeper bond between them. Regarding Naruto's relationships with Akatsuki members, he would have to navigate their different personalities and agendas. Some might become his allies, while others would remain enemies. And Sakura's standing in Konoha might be questioned as she defends Naruto's actions.
The relationship between Naruto and Sakura would become much more strained yet also more intense. Sakura would be constantly worried about Naruto's safety in Akatsuki. Naruto, on the other hand, would be in a difficult position as he's in an enemy organization but still cares about Sakura and Konoha. His relationships with the Akatsuki members would also be complex. Some might see him as an opportunity, while others might be hostile. Sakura's relationship with the rest of Konoha would also be affected as she tries to support Naruto from afar.
Naruto's relationship with his sensei, Kakashi, would be severely strained. Kakashi has always been a guiding figure for Naruto, and Naruto joining the Akatsuki would seem like a betrayal. However, Kakashi might also suspect that Naruto has an ulterior motive. As for his relationships with the other Konoha ninjas, they would be filled with suspicion and mistrust. But Naruto could also form new relationships within the Akatsuki. He might befriend some of the members who have a bit of good in them, like Konan perhaps, and together they could work towards a new future for the Akatsuki.
Naruto's relationship with Kisame might become an interesting one. At first, Kisame would likely be very suspicious of Naruto. But as time goes on, Naruto's determination and strength could earn Kisame's respect. With Itachi there, he might be more open - minded towards Naruto. As for Kakuzu, Naruto would probably constantly clash with him due to Kakuzu's money - loving nature. Naruto would try to convince him that there are more important things than wealth. And with Sasori, Naruto would be horrified by Sasori's use of human puppets and would try to make him see the value of human life.
His relationship with Sasuke would become even more complex. Sasuke might see Naruto's joining of Akatsuki as a betrayal or a sign that Naruto has finally given up on Konoha. Naruto's old friends in Konoha, like Sakura and Kakashi, would be very confused and hurt. They might try to bring him back, but also be wary of his new Akatsuki ties. And within Akatsuki, Naruto would have to navigate relationships with members who have different motives and personalities, some of whom might not trust him at all.
His relationships with his old friends in the Hidden Leaf would become extremely strained. They would see him as a traitor. For example, Sakura might be heartbroken and angry at him. Kakashi would be disappointed. However, within Akatsuki, he could form new relationships. He might become friends with some of the members who have a similar background of being misunderstood. For instance, he could bond with Hidan over their strong beliefs, though their beliefs are very different in nature.
If evil Naruto were to join Akatsuki in fanfiction, the story's moral compass would shift. Akatsuki is already seen as a villainous group, but with Naruto on board, it becomes even more of a gray area. Naruto's relationships with characters like Kakashi and Jiraiya would be completely different. They would probably try to save him from his evil ways, but it would be much more difficult. The power struggles within Akatsuki would intensify as members vie for Naruto's loyalty or try to keep him in check. And the overall plot would likely focus more on Naruto's actions and how they impact the ninja world in this new, dark role.
His relationship with Sasuke would be extremely interesting. Instead of being rivals from different sides, they could become comrades within the Akatsuki. This would change the whole dynamic of their relationship, as they might now work together towards the Akatsuki's goals, at least for a while.
His relationship with Sasuke would be extremely complex. Sasuke, who has his own vendetta against the shinobi world, might initially be suspicious of Naruto's new role. But Naruto, as the Akatsuki leader, would try to convince Sasuke to join him in his new vision for the organization. It could be a love - hate relationship where they constantly butt heads but also understand each other on a deeper level.
His relationship with Sasuke would be drastically different. Instead of being rivals from the Leaf Village, they could be on opposite sides. Sasuke might see Naruto as a traitor to the Leaf and Naruto might see Sasuke as someone who doesn't understand the Akatsuki's motives. With Sakura, Naruto might not have the same protective feelings. He could view her as just another ninja from a village that the Akatsuki has issues with.
Naruto's relationships would shift significantly. In Kirigakure, he'd have to form new friendships with local ninjas. These relationships would be based on different foundations compared to his Konoha friends. He might find it hard to trust at first. And his relationship with Kakashi would also change. Kakashi would probably be concerned about Naruto's new situation but also respect his decision to some extent. Naruto would have to start from scratch in building trust and camaraderie in Kirigakure.
Naruto and Sasuke's relationship might become more complex. On one hand, they are in a new and dangerous environment together, which could strengthen their bond as they rely on each other. But on the other hand, the ideology of Akatsuki might put some strain on their relationship if they have different views on how to handle the situation within the organization. For example, Sasuke might be more inclined to use force while Naruto tries to find a more diplomatic solution.
