The training could strengthen their bond. They have to work together to teach the young one, so they need to communicate better. For example, Naruto might suggest a more fun - filled training method, and Sasuke might initially oppose it but then see the value in it. This back - and - forth can make them understand each other's perspectives more, just like in their own growth as friends.
The training could also bring up old issues between them in a positive way. They might remember past training sessions they had together or arguments about the best way to train. But now, with the young fan as a common goal, they can resolve those issues. For instance, Sasuke might have once thought Naruto's way of training was too sloppy, but now he realizes that it can bring out a certain creativity in the young fan that his own method lacks, leading to a more harmonious relationship between them.
As for the other Konoha 11 members, they might initially be skeptical. But as they see how Sasuke is changing for the better under Naruto's adoption, they start to include him more in group activities. They come to respect Naruto's decision and see Sasuke in a new light, which gradually strengthens the overall unity among them.
It could make their peers jealous. For example, characters like Shikamaru might feel that Naruto and Sasuke are getting special treatment. But for their mentors, it could strengthen the bond. Kakashi might have more faith in them and train them more intensively. And for Sakura, she might be both proud and a bit envious of Sasuke's early graduation.
Their relationship could develop as they start to respect each other's skills more. As they train, they see the hard work and determination in each other, which makes them put aside their past grudges. For example, when Naruto manages to dodge one of Sasuke's powerful attacks, Sasuke realizes that Naruto has truly become stronger. This makes him more open to working with Naruto rather than against him.
Well, in a lot of fanfiction, their love for each other is depicted as a soul - deep connection. They understand each other on a level that no one else does. Their relationship might be shown with a lot of emotional moments. Like when they reunite after a long time apart, there are intense feelings of relief and joy. Also, some fanfics may explore a more romantic side of their relationship, with tender glances and gentle touches.
In some fanfictions, there are special abilities or bonds that enhance their understanding. Maybe a magical connection that allows them to feel each other's emotions. This makes it easier for them to know what the other is thinking or feeling at any given moment. So, when one is in danger or has a strong emotion, the other can sense it and respond accordingly, deepening their understanding of one another.
It could make Sasuke more protective of Naruto. Sasuke has always had a complex relationship with Naruto, and seeing him lose an arm would stir up some deep emotions. He might feel guilty, especially if he was somehow involved in the incident that cost Naruto his arm. This could lead to Sasuke staying closer to Naruto and being more open about his feelings.
In fanfiction, the 'hot sauce punch' might be a turning point. It could make Sasuke realize that Naruto still has that goofy side and it might soften his cold exterior. On the other hand, if Naruto uses it out of anger, it could deepen the rift between them. For example, if Sasuke has just made a decision that Naruto strongly opposes, the punch could be a physical manifestation of his frustration.
In some fanfictions, the curse mark can initially drive a wedge between Naruto and Sasuke. Sasuke might become more withdrawn and brooding due to the power and dark influence of the curse mark. Naruto, on the other hand, would be worried about his friend but might not fully understand what Sasuke is going through. This could lead to some misunderstandings and arguments between them as Naruto tries to reach out while Sasuke pushes him away.
Well, with Minato alive, Naruto would have a stronger family support system. This would likely make Naruto less eager to prove himself through Sasuke. And for Sasuke, seeing Naruto having a complete family with Minato might stir some complex emotions in him. Maybe envy at first, but later it could lead to him being more open to Naruto's friendship. Minato could also act as a mediator between the two, guiding them to understand each other's pain and dreams better, thus forging a stronger bond between them.
The training could disrupt the power balance in the Naruto universe. Naruto would become much stronger than most of his opponents. It might also introduce new concepts like ki into the Naruto world, which could change how battles are fought.
