Naruto would grow in his understanding of the ninja way. He's always been a bit of a maverick, but Hagoromo's training could give him a more traditional yet enhanced view. His bonds with others would become even stronger, and he would be more of a leader in the ninja world. Sasuke would start to let go of some of his past grudges. Hagoromo's wisdom could show him that holding onto so much hate is not the way forward. He would become more focused on protecting the ninja world rather than just seeking power for his own reasons. Their characters would evolve to be more rounded and in line with the greater good of the ninja world.
Naruto's character could experience a spiritual awakening. Since Hagoromo is such a powerful and spiritual figure, Naruto would be exposed to new ways of thinking about chakra and life itself. This could make him more empathetic towards his enemies. Sasuke would have a shift in his values. He would no longer see power as the only thing that matters. Hagoromo's training would make him realize that there are other important aspects in the ninja world, like peace and harmony. They would both become more like the ideal ninja that Hagoromo might have envisioned, with Naruto's cheerfulness and Sasuke's intensity being channeled in more positive directions.
In this fanfiction scenario, their teamwork could reach a new height. Hagoromo would likely train them together, so they would understand each other's strengths and weaknesses better. Naruto's optimism and Sasuke's more brooding nature could be balanced out under Hagoromo's guidance. They might also learn new joint - attack techniques. For example, they could combine Naruto's Rasengan and Sasuke's Chidori in a way that is more powerful and versatile than before. Their bond as friends and comrades would be strengthened, and they would be better equipped to face any future threats to the ninja world.
Naruto's character would develop in several ways. He'd become more patient as Hagoromo's teachings are likely profound and require time to absorb. His sense of responsibility would grow even more. Since Hagoromo has a deep connection to the history of the ninja world, Naruto would also gain a greater respect for the past and traditions. This new - found knowledge would make him a more well - rounded leader, not just a powerful fighter.
Naruto would probably become more confident in his abilities. Since he has the Kyuubi inside him, with proper training from it, he could be less impulsive and more strategic in using his power. Sasuke might become more empathetic. He'd understand Naruto's connection to the Kyuubi better and might see that there are other ways to gain power than just through revenge. Overall, their relationship could also deepen as they share this unique training experience.
In a fanfiction where Naruto and Hinata are trained by Hagoromo, their relationship would experience significant growth. The training would be intense, and they would need to trust each other completely. This trust - building process would be crucial for their relationship. Naruto, being the more outgoing one, would encourage Hinata when she faces difficulties. Hinata, with her gentle and supportive nature, would be a great source of comfort for Naruto when he struggles with the new training. As they progress in their training, they would start to share a deeper connection, not just based on their previous feelings but also on the mutual respect and admiration they gain from seeing each other's growth. This would ultimately lead to a more harmonious and loving relationship between them.
In such a fanfiction, Naruto might quickly master powerful jutsus. Hagoromo could teach him the secrets of chakra that no one else knows. Naruto would likely become extremely powerful, maybe even unlocking new forms of Sage Mode or a unique power related to Hagoromo's own abilities.
Naruto's development in this fanfiction could be complex. He would have to balance his own identity with that of Hagoromo. At first, he might struggle with the sudden influx of new powers and the weight of Hagoromo's legacy. But as time goes on, he would grow into it. His relationships with others would also change. For example, his bond with Sakura could shift as he becomes more in tune with Hagoromo's powers. His leadership skills would also improve, as he is now a symbol of a new era in the ninja world, carrying the essence of Hagoromo within him.
In this kind of fanfiction scenario, Naruto and Hinata would likely gain extremely powerful abilities. Naruto already has a connection to Hagoromo through his Sage of Six Paths powers. With direct training, he could master new jutsu and control his power more precisely. Hinata, on the other hand, would be able to enhance her Byakugan skills and maybe even develop new techniques related to the Otsutsuki power that Hagoromo possessed. They could also gain a deeper understanding of the ninja world's history and the true nature of chakra, which would make them even more formidable in battles and in protecting the Hidden Leaf Village.
In many such fanfics, Naruto's character often becomes more vulnerable yet also stronger in a different sense. His pregnancy makes him rely on Sasuke more, but at the same time, he is determined to still be a great ninja. Sasuke, on the other hand, becomes more nurturing. He steps up to protect Naruto and the unborn child, showing a side of him that was not as evident before.
Naruto's character might become more cynical as a missing - nin. He's been rejected by the village he loved, so he could lose some of his naivete. He might also become more of a lone wolf, relying on his own strength rather than the power of friendship like he used to. Sasuke, however, could start to soften. Away from the influence of Orochimaru and his revenge - driven past, he may see the value in Naruto's way of thinking more. For example, he might start to care about the well - being of others outside of his own goals.
His view of the world would expand. Naruto, who was mainly focused on the ninja world, would now be exposed to the magical world through Merlin. This would make him more open - minded and understanding of different cultures and powers. He may also start to use his newfound knowledge to try and bring peace not just between ninja villages, but also between the ninja world and the magical realm Merlin comes from.
