Their relationship could be one of rivalry. The brother might feel overshadowed by Hagoromo and see Naruto as a way to prove himself. So, he initially tries to use Naruto against Hagoromo's ideals but later realizes the error of his ways and becomes an ally to Naruto.
It could be a mentor - mentee relationship. The brother, having great knowledge and power, decides to guide Naruto. He sees in Naruto the potential to be a great leader like Hagoromo. He shares his wisdom about chakra control and ancient ninja arts, and Naruto respects him as a teacher, just like he did with Jiraiya.
In some fanfictions, it might be possible for Naruto to be depicted as Hagoromo's brother, but this is completely a creative and non - canonical concept. Fanfiction allows for such wild and imaginative ideas to explore different relationships and storylines.
Well, in fanfiction, if Naruto is the brother of Hagoromo, it would have far - reaching implications. Firstly, Naruto's status would be elevated to an almost god - like level. His every action would be seen in the context of his relation to Hagoromo. His journey as a ninja would likely be different. He might not face as much opposition or might be expected to fulfill different prophecies. His relationship with Sasuke could also take on a new dimension. Maybe Sasuke would see Naruto in a different light, either as a more powerful rival or as someone who he needs to follow or support more. And in terms of the plot, the story could explore new conflicts, like those arising from Naruto's new - found status and how it affects the balance of power in the ninja world.
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.
Well, in a fanfiction, it's possible. One way to write it could be by creating a whole new backstory for Naruto. Maybe there was some sort of time - travel or alternate dimension thing. Naruto could have been sent back in time and ended up as Hagoromo's brother. It would be really interesting to explore how Naruto's modern - day values and skills would interact with the ancient world Hagoromo was from.
One interesting plot twist could be that Naruto actually has a hidden power that is the key to Hagoromo's own power development. Maybe Hagoromo has been struggling with something in his power growth, and Naruto's presence unlocks it. Another could be that Naruto is from the future, and his knowledge of future events causes a huge shift in the way things are supposed to happen in Hagoromo's time.
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.
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.
Well, it would completely change the Naruto timeline. Hagoromo was the one who started many of the ninja traditions and powers. If Naruto was his father, it would mean Naruto had a much greater impact on the early days of the ninja world than in the original story. Also, Naruto's values like friendship and never giving up would likely be passed down to Hagoromo in a different way, perhaps influencing how Hagoromo developed the ninja way.
They would likely have a very strong bond. Since they are brothers, they would support each other in battles and in their personal growth.
Perhaps Hagoromo's brother was wrongly accused of something in the past and sealed away. Naruto discovers his existence and frees him. In return, the brother tells Naruto the true history of the ninja world, including secrets about the origin of chakra that no one else knows. This knowledge helps Naruto to bring about a new era of peace and understanding among all the ninja clans.
