Naruto's relationship with the other students from important clans could also change. The Hyuga or the Inuzuka might see Naruto as a more worthy opponent or even a potential ally. They would notice his early training and skills and might approach him differently. This could lead to a more complex web of relationships at the academy, with Naruto being more in the center of things rather than an outcast. And his relationship with Kakashi later on might also be affected, as Kakashi would notice Naruto's different skill set and attitude which was shaped by Itachi's early training.
His relationship with Iruka could be different. Iruka might notice Naruto's advanced skills and be more curious about his background. He could become more of a mentor - like figure to Naruto in a different way, guiding Naruto on how to use his skills in a proper and ethical way within the academy environment. Also, Naruto's relationship with Sakura could be less one - sided. With his new - found confidence and skills, Naruto could interact with her on a more equal footing, instead of just chasing after her blindly.
Naruto might be more confident in his relationships. Since he has received training from Itachi, he would be more self - assured. He might not be as eager to prove himself in a brash way as in the original story, which could lead to better relationships with his classmates. For example, he wouldn't constantly challenge Sasuke in a show - of - strength manner.
One possible plotline could be that Itachi sees Naruto's potential even at a young age. He might start teaching Naruto basic ninja skills like stealth. For example, Itachi could show Naruto how to move quietly in the forest without making a sound. This early training could give Naruto an edge when he later enters the academy, as he would already have a foundation in some ninja arts.
His understanding of the Uchiha and the darker side of the ninja world would deepen. Itachi would share his experiences, and Naruto would gain a more nuanced view. This might make him more empathetic towards enemies. Also, his combat skills would diversify. He could incorporate Itachi - like precision and speed into his fighting style, becoming a more well - rounded ninja.
Naruto would likely become more stealthy. Itachi is known for his stealth and if he trains Naruto, Naruto would pick up some of those skills. He might start to rely less on his brash and straightforward fighting style and incorporate more subtlety.
Naruto would be more confident. In the original, he was often bullied and looked down upon. But with Kurama's training, he would have a sense of self - worth and power early on. He might not be as loud and boisterous, as he now has real strength to back him up.
It could be an old, retired ninja who lives on the outskirts of the village. This person has seen the hardships Naruto faces and decides to take him under their wing.
In such a fanfiction, one possible plot could be Naruto training in secret. Maybe he discovers an old, hidden training ground in the village. He starts practicing basic ninja skills like shuriken throwing and tree climbing on his own. This early training could give him an edge when he finally enters the academy, making him stand out among his peers.
Their friendship could also lead to a different perspective on the Uchiha clan's situation. Itachi's actions were complex and his friendship with Naruto could have made Naruto more involved in the Uchiha clan's affairs. This might have led to a different solution to the conflict between the Uchiha clan and Konoha, preventing the massacre. In turn, this would have a huge impact on the political situation in the ninja world.
Naruto may become more calm and composed. Itachi's presence and training methods would likely instill a sense of discipline in Naruto. He'd probably be less impulsive in battles and think more before acting.
Well, in a fanfiction where Naruto is trained by Itachi in Sharingan, Naruto would first have to adapt to the new power. Itachi would probably start with the basics of how to activate and control the Sharingan. Since Naruto is used to his own physical and chakra - based training, this would be a challenge. However, with Itachi's guidance, he could master it. Once he does, he could use the Sharingan to analyze his opponents' fighting styles better. For example, he could quickly figure out the weaknesses in an enemy's jutsu and counter them effectively. He could also use the Sharingan's visual prowess to enhance his reaction time during battles.
Itachi's influence would make Naruto more empathetic towards the Uchiha clan. He would understand their side of the story better. This would change his approach to dealing with the conflicts related to the Uchiha. Also, Naruto would be more skilled in stealth and strategy. Itachi's training would focus on these aspects, and Naruto would develop into a more well - rounded ninja, with both power and finesse.
