A main plotline could be Naruto being trained in ancient ninja arts that Hagoromo knew. These arts could be lost to the modern ninja world. So, Naruto would have an edge in battles. For example, he could learn some unique sealing techniques that were forgotten over time. This would make him a target for those who want to use his skills for their own gain. Another aspect could be Naruto's relationship with the other villages. With Hagoromo's influence, he might try to establish a more equal and peaceful co - existence among all the villages from a very young age. He could also be involved in uncovering secrets about the origin of the ninja world that Hagoromo knew but were long forgotten.
One possible main plotline could be that Naruto and Hinata, under Kyuubi's influence, grow up with a different understanding of power. They might be more in tune with the fox's chakra from a young age, leading to them developing unique ninja techniques. For example, Naruto could combine his natural Uzumaki resilience with Kyuubi - influenced skills earlier. Hinata, too, might gain confidence faster as the Kyuubi could instill a sense of protection in her. This could change the way they interact with their peers and the village as a whole.
The plot could also involve a time - related crisis. Maybe something is threatening the timeline, and the only way to fix it is for future Naruto to raise his younger self in a certain way. So, future Naruto has to make sure that the younger Naruto grows up to be strong enough to face this threat while also maintaining the integrity of the timeline.
Perhaps it could be another entity related to Hagoromo. If Naruto abandons Hagoromo, there might be a counterpart or a follower of Hagoromo who sees Naruto as a threat or a traitor. This person could then become the main antagonist, trying to either bring Naruto back to Hagoromo's side or simply eliminate him.
One possible main plotline could be Naruto growing up with Kakashi's unique training methods. Since Kakashi is known for his strict and strategic training, Naruto might develop different skills compared to the original series. Another plotline could be how Naruto deals with the abandonment issues from his past while having Kakashi as a father figure. He could struggle with trust issues at first but gradually open up as Kakashi shows him unconditional love and support.
One possible plotline could be that Naruto grows up with a different set of values. Mikoto might teach him more about the Uchiha clan's ways, which could influence his fighting style. He may also have a closer relationship with Sasuke from the start as they are both in the same 'family' of sorts.
In a Naruto raised by Yugao fanfiction, perhaps Yugao would instill in Naruto a deeper sense of loyalty to Konoha. Since she is a dedicated shinobi herself, she could raise Naruto with stories of Konoha's heroes and the importance of protecting the village. This might lead to Naruto having an even stronger bond with Konoha from an earlier age.
One possible plotline could be that Iruka instills in Naruto a deeper sense of self - worth from a very young age. Since Naruto has always been starved for recognition, Iruka's positive influence might make Naruto more confident in his abilities earlier. For example, he could start training more seriously and master certain jutsu faster. Another plotline might involve Iruka protecting Naruto from some of the harsher elements in the village that Naruto would have otherwise faced alone. This could lead to a different dynamic between Naruto and the villagers as they might see Naruto in a new light because of Iruka's actions. A third plotline could be that Iruka, being Naruto's main caregiver, helps Naruto understand his parents better. Maybe Iruka discovers some hidden secrets about Naruto's parents and shares them with Naruto at the right time, which gives Naruto a new sense of purpose and connection to his family heritage.
One possible plotline could be her training. Since Kakashi is known for his unique and challenging training methods, he might train her differently from how Naruto was trained in the original. For example, he could focus more on her stealth and precision, which could lead to a new kind of ninja that Naruto becomes. Another aspect could be how she deals with the expectations of being Naruto in a different gender. She might face different kinds of prejudice or support. And also, her relationships with other characters like Sasuke and Sakura would be very different. Sasuke might see her in a different light, and Sakura could have a more sisterly or competitive relationship with her.
One possible plotline could be that Naruto inherits Sakumo's calm and strategic mindset. Since Sakumo was known for his intelligence in battle, Naruto might grow up to be a more cerebral ninja. He could also learn Sakumo's unique jutsu and techniques, which would set him apart from his canon self. Another aspect could be how Naruto's presence affects Sakumo's fate. Maybe Naruto's positive attitude and will to change things could prevent Sakumo from succumbing to the despair that led to his downfall in the original story.
One possible plot could be that Naruto discovers he is a reincarnation of Hagoromo. This leads to him having to deal with newfound powers and responsibilities. He might have to face an ancient evil that only he, as Hagoromo's reincarnation, can defeat.
