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.
Naruto's character would likely be more reserved in some ways. Kakashi is a rather stoic and composed person, and his influence might make Naruto less brash. Instead of always charging headfirst into situations, he would think more. For example, in battles, he might analyze the situation like Kakashi does before acting.
Well, Naruto's character would be different in many ways. Firstly, he'd have a stronger sense of discipline. Kakashi would instill in him the importance of following rules and regulations in the shinobi world. His view of friendship might also be different. While he'd still value his friends, he might be more guarded initially, as Kakashi might teach him to be cautious. His relationship with the Hokage and the village elders would also be distinct. He might have more respect for their authority due to Kakashi's influence, but at the same time, he could be more critical of their decisions if he felt they were not in the best interest of the village, based on the knowledge and values Kakashi has imparted to him.
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.
It could be due to a misunderstanding. Kakashi might think that Naruto is getting involved with something dangerous or has some potential that he can't handle. So, in his warped way of thinking, he abandons Naruto to protect him from himself or from some unknown danger.
Naruto could initially feel a great sense of loss and sadness. But as time goes on, he might start to look for new mentors or friends who can support him. For example, he could turn to Iruka-sensei more often or form closer bonds with his fellow classmates like Shikamaru or Choji. He'd rely on his inner strength and the relationships he already has to get through this tough time.
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.
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.
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.
