If Naruto were part of the Akatsuki in fanfiction, his character would transform in multiple ways. His jovial and upbeat nature might be subdued as he's in a more somber and serious environment. He'd have to adapt to the Akatsuki's hierarchy and rules, which could make him more disciplined but also more withdrawn. His relationships would be strained as he'd be on the 'opposite side' from his friends in Konoha. He might develop a new set of values, as the Akatsuki's goals, though extreme, could seem appealing in some ways. For instance, their idea of creating a new world order might make Naruto re - evaluate what true peace really means, and he may try to find a way to combine the Akatsuki's vision with Konoha's values to create a more inclusive and sustainable peace.
Naruto's character would change significantly. Firstly, he would be more secretive. In Konoha, he was an open book, but in the Akatsuki, he'd have to keep his true intentions hidden. His sense of loyalty would be tested as he'd be in a group that opposes his former home. He may also become more calculating. For example, he'd need to figure out how to use the Akatsuki's resources to his advantage while also trying to protect Konoha in the long run. He would no longer be the naive boy who always rushed into battle; instead, he'd have to think several steps ahead.
His character would become more conflicted. He'd have to balance his own beliefs with the Akatsuki's motives.
Naruto joining Akatsuki in fanfiction would turn his relationships upside down. His friends in the Leaf would initially feel betrayed. However, some might start to question if there's more to Naruto's decision. His relationship with Akatsuki members would be a mix. He'd be constantly in a tug - of - war with Itachi, who has his own plans regarding Naruto. And his interactions with Pain would be intense, as Pain represents a very different ideology from Naruto's. Naruto would have to struggle to find common ground or at least a way to coexist with these new 'comrades' while still holding onto his own values.
His relationship with Sasuke would become even more complex. Sasuke might be suspicious of Naruto's motives for joining Akatsuki, thinking he has truly turned to the 'dark side'. Or, they could end up on opposite sides of a conflict within Akatsuki itself if their goals within the organization differ.
If Naruto was trained by the Akatsuki in fanfiction, his relationships would be completely transformed. For starters, his relationship with Kakashi would be strained. Kakashi has always been Naruto's mentor in a way, and seeing Naruto side with the Akatsuki would be a shock. His friends like Sakura and Shikamaru would also be confused and probably try to bring him back to the 'right side'. And his relationship with the villagers of Konoha would turn sour as they would fear his new - found Akatsuki - related powers.
His personality might become more guarded. He'd be surrounded by people who are mostly out for themselves or have very different values from him. So, he'd need to be more cautious in showing his true self.
If Naruto joined the Akatsuki, his relationship with the other Akatsuki members would be diverse. Some, like Hidan, might see him as an enemy no matter what. But others, like Konan, might be more open to him. She has a more complex view of things compared to some of the more blood - thirsty members. Naruto would also have to deal with the Akatsuki's leader, Pein. Their relationship could range from mutual respect to outright hostility depending on Naruto's actions and goals within the organization.
If Naruto is trained by Akatsuki in fanfiction, his skills would be transformed in multiple ways. His chakra control could be refined to a much higher level. Akatsuki members are experienced in dealing with large amounts of chakra, and they could teach Naruto how to better manage his own vast reserves. His combat strategy would shift from the more straightforward and honorable style of Konoha to a more cunning and adaptable approach. He might also gain knowledge about sealing techniques that the Akatsuki has used to capture tailed beasts. This new knowledge could not only enhance his fighting abilities but also give him an edge in dealing with other threats in the ninja world. His ability to sense and counter opponents would be sharpened as well, as the Akatsuki often deals with dangerous and powerful foes.
Naruto's relationships would change drastically. His friends might be in awe of him or even a bit afraid. He would no longer be just the goofy ninja they knew. He would have a new level of power and responsibility. And his enemies would be much more cautious around him, knowing that he has the might of a Greek god behind him. His entire personality would shift to adapt to this new status, while still retaining some of his core ninja values.
His relationships would be completely turned upside down. His friends in the Leaf Village would be confused and hurt. Meanwhile, in Akatsuki, he'd have to build new relationships. Some members might be hostile at first, but others could potentially become comrades. For example, he might form an unlikely bond with Hidan, who is very different from Naruto in beliefs but they could learn from each other in a strange way.
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.
