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.
Maybe Itachi trains Naruto in chakra control. He could teach Naruto how to climb trees using chakra, which is a fundamental skill. This would make Naruto more confident and advanced compared to his peers when he starts at the academy. Also, Itachi might pass on some of his knowledge about the Sharingan, not the ability to use it, but how to recognize and counter it. This would be very useful for Naruto in future battles against Uchiha opponents.
Itachi could also train Naruto in terms of mental strength. He might tell Naruto stories about the harshness of the ninja world and how to face difficulties. This would shape Naruto's mindset early on. For instance, Naruto would learn not to be afraid of strong opponents but rather see them as challenges to overcome. In the fanfiction, this early training by Itachi could lead to Naruto being a more well - rounded ninja by the time he enters the academy, and it could also change the way some of his classmates and teachers perceive him.
The plot could involve Kurama teaching Naruto how to use his own chakra more efficiently. Since Kurama is a powerful source of chakra, he can guide Naruto on how to tap into his inner strength. Maybe Naruto starts to show extraordinary abilities in front of the villagers even before the academy, which causes both fear and admiration. This early training could also lead to Naruto having a different attitude towards his studies at the academy as he already has some skills.
One possible plotline could be that they become closer friends early on. Since they are the same age, they might train together more often. They could also share secrets that in the original story they wouldn't due to the age gap. For example, they might both have dreams about the future of the village that they can discuss on an equal level.
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.
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 Naruto is forced into a situation where he has to kill Itachi to protect the Hidden Leaf. Maybe Itachi is being controlled by some dark force and Naruto, with great reluctance, has to end his life to save the village and his friends.
Well, perhaps Itachi is under the influence of a genjutsu himself when he captures Sakura. He could be acting against his own will. Sakura, in this situation, might try to break the genjutsu on Itachi while also trying to free herself. And during this time, she could discover some secrets about Itachi's past or his true motives that were hidden before. This could lead to a complex relationship between them where Sakura has a new perspective on Itachi, not just as an enemy but as a victim too.
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.
One possible plotline could be that Naruto is somehow tricked into leaving with Kisami and Itachi. Maybe they convince him that there is a greater threat that only they can help him face. Along the way, Naruto might start to learn more about their motives and the secrets of their pasts. He could also be in a position where he has to use his own skills and values to influence them.
In this fanfiction, Itachi might also train Naruto in the ways of the Sharingan. Even though Naruto doesn't have the Sharingan naturally, Itachi could find ways to make Naruto understand the principles behind it, like how to read an opponent's movements more accurately. This could lead to Naruto having an edge in battles against opponents who rely on speed and deception.
One possible plot could be that Itachi, seeing Naruto's potential and his importance for the future of the Hidden Leaf, decides to secretly train him. Itachi might teach Naruto advanced jutsu, especially those related to chakra control and unique Sharingan - inspired techniques. Naruto, under Itachi's tutelage, would grow not only in power but also in his understanding of the ninja world's complex politics and the Uchiha clan's history.
