Their relationship could become more of a partnership. With Naruto as Hokage, Sasuke might be more willing to work within the village's framework. They would still have their friendly rivalry, but it would be more focused on making the village better.
Well, Sasuke could initially be a bit resentful. He's always been a bit of a lone wolf. But as Naruto proves to be a great Hokage, Sasuke starts to see the value in what Naruto is doing and becomes more of an ally. He might even start to train the next generation of ninja alongside Naruto, strengthening their bond in the process.
They still have that deep friendship, but it's more official. Naruto as Hokage respects Sasuke's views on matters related to the outside threats. Sasuke, on the other hand, respects Naruto's leadership. They often meet to discuss strategies and how to keep Konoha and the ninja world in peace. For example, they might plan together how to deal with any potential threats from rogue ninjas or other villages.
The dynamic would shift a bit. Naruto would have to balance his friendship with Sasuke and his duties as Hokage. He would probably try to bring Sasuke more into the fold of the village, making him feel like a true part of it. Sasuke, in turn, would start to see the village in a new light, through Naruto's leadership. Their relationship would be a key factor in the stability and growth of the village.
In this fanfiction scenario, Sasuke might be jealous of Naruto's new power at first. He has always been competitive with Naruto, and seeing Naruto become something so powerful as the Kyuubi could trigger that jealousy. However, when they face a common enemy together, Sasuke sees that Naruto is struggling to control the Kyuubi's power and needs his help. This could lead to a new level of understanding and friendship between them, as they work together to help Naruto master his new form.
Naruto's personality might become more reserved in some ways. As Hokage, he has to represent the village in a more solemn and diplomatic manner. He can't be as carefree as he used to be. For example, in international meetings, he has to think carefully about his words and actions.
Naruto could become cold due to disappointment. He might have expected Sasuke to rule in a certain way, but when Sasuke becomes Hokage and starts making decisions that seem contrary to Naruto's ideals, Naruto feels let down. This disappointment could turn him cold towards Sasuke and the village in general.
In many time travel fanfictions, their relationship often becomes more understanding. Since they already know each other well in the future, when they travel back, they can skip the initial hostilities. For example, if they go back to their academy days, Sasuke might not be as cold to Naruto as he was originally because he already knows Naruto's true nature and what they will go through together in the future.
Well, usually it starts with Sasuke realizing his newfound leadership role. He might struggle at first with the political side of being Hokage, which is very different from his combat skills. Naruto would be there to support him, of course. And then they would face some new threats to the village together. The story could also explore how Sasuke changes the way the village is run, maybe bringing in some new ninja training methods inspired by his own experiences.
Naruto could change Konoha by promoting unity. He might organize village - wide events where everyone, from the strongest jounin to the youngest genin, participates. This would strengthen the bonds between the villagers.
Naruto becoming a Jounin might make Sasuke re - evaluate their relationship. He might see Naruto in a new light, as someone who has achieved a lot and is now a respected figure in the village. This could lead to a more stable and understanding relationship between them. Maybe Sasuke would be more open to working with Naruto on things like protecting the village and training the next generation of ninjas.
Naruto's relationship with the older generation like Tsunade would change significantly. Tsunade, being the former Hokage, would now be in an advisory role. Naruto would seek her advice on matters of the village's economy and long - term stability. With his peers like Kiba, Naruto would be more of a guiding figure. Kiba would look up to Naruto as the Hokage and might ask for more challenging missions for his growth. And with Hinata, their relationship could become more official. As Hokage, Naruto would have to balance his personal life with Hinata and his duties towards the village.
