If Naruto was raised by Kakashi in fanfiction, their relationship would be very different from the original. Kakashi could teach Naruto more about the Sharingan and its secrets since he has one. Naruto might also inherit some of Kakashi's reading habits and love for Icha - Icha Paradise, which could lead to some really funny moments.
One possible plot could be that Naruto would grow up with more refined ninja skills. Kakashi could teach him his signature jutsus like the Chidori in a more in - depth way. Kurenai might focus on Naruto's genjutsu skills, which he lacks in the original. With their combined guidance, Naruto could become a more well - rounded ninja at an earlier age.
He'd probably be more reserved. Kakashi is not as boisterous as some others, so Naruto might pick up on that. For instance, he might not shout as much about becoming Hokage right away.
Often, in 'naruto gets trained by kakashi fanfiction', Naruto will face various challenges during the training. These challenges could be physical, like enduring intense sparring sessions with Kakashi. Or they could be mental, such as understanding complex ninja concepts. Through these experiences, Naruto not only becomes more powerful but also gains a deeper understanding of himself and his ninja path. This might also lead to him forging a stronger bond with Kakashi, which could play a significant role in future plot developments.
One possible plot could be a dark turn in the story. Maybe Kakashi is under some kind of mind - control. He could be forced to fight Naruto by a powerful enemy who has taken over his mind. Naruto, being unprepared for such an attack from his mentor, gets killed. This would then lead to a series of events like Sasuke going on a rampage to find out the truth and avenge Naruto, and the whole ninja world being in shock as one of their most promising heroes is gone.
Kakashi would probably focus more on stealth training. In the original, Naruto was more about big, flashy attacks. But Kakashi would teach Naruto how to move quietly and strike unexpectedly. He might also teach Naruto more about chakra control from the very beginning. In the original, Naruto struggled with this for a while. And Kakashi would surely introduce Naruto to some of his own unique jutsu earlier, like the Chidori, but with Naruto's own spin on it.
In such a fanfiction, Naruto might become more strategic from an early age. Kakashi's intelligent and cautious fighting style could influence Naruto. He might teach Naruto more about the Sharingan he got from Obito earlier, which could make Naruto's combat skills more diverse.
In this 'naruto raised by kakashi fanfic', a great plot point might be the relationship development between Naruto and the other characters through Kakashi's influence. Kakashi could introduce Naruto to new friends or allies. For instance, he might take Naruto on missions with his old comrades, like Gai. This would not only expose Naruto to different fighting styles but also help him form new relationships, which is important for his growth as a ninja.
In this fanfiction, a great plot development could be the impact on the story's antagonists. Since Naruto is being raised differently, his growth might be noticed earlier by the likes of Orochimaru or the Akatsuki. This could lead to earlier and more intense confrontations. Moreover, Kakashi's influence on Naruto's moral code could make Naruto more of a grey - area character. He might be more willing to make tough decisions and sacrifices for the greater good, which would completely change the course of many story arcs.
In some fanfictions, it could be due to a special jutsu gone wrong. Maybe a jutsu that Kakashi was using to transfer some of his chakra to Naruto for a mission accidentally transferred his Sharingan power as well.
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.
