Without Kakashi's training, Naruto could also turn to the village elders or other jonin for advice. He might stumble upon some ancient ninja scrolls or artifacts that help him in his training. This would lead to a more self - discovery - based journey for Naruto. He would have to figure out things on his own, make mistakes, and learn from them. This would make his character growth more organic and relatable to the readers.
The story could introduce a new character as Naruto's mentor. This character might have a completely different teaching style compared to Kakashi. Maybe this new mentor focuses more on spiritual growth rather than physical combat skills. As a result, Naruto would develop in a new and unexpected direction, which would make the fanfiction more interesting. For instance, Naruto could learn more about the history and philosophy of the ninja world, which would give him a deeper understanding of his role as a ninja.
Another reason could be that in this fanfiction, the plot is set in a way that there is a new training system in the village. And this system doesn't involve Kakashi in Naruto's training. There could be new mentors or a completely different approach to training young ninjas like Naruto, which excludes Kakashi from the equation.
Naruto might also try to find alternative ways to gain strength. He could explore the forest around the village to find new training areas or discover new chakra - related phenomena. He has a curious nature, and this could lead him to stumble upon something that gives him an edge in his training, like a hidden hot spring that has special chakra - enhancing properties.
In this fanfiction, Kakashi could help Naruto in his training through mental conditioning as well. Naruto is often impulsive, so Kakashi may work on his patience and decision - making skills. He could use his Sharingan (if applicable in the fanfiction) to analyze Naruto's movements during training and give him detailed feedback. Moreover, Kakashi could introduce Naruto to different types of enemies and battle scenarios in a controlled training environment, which would broaden Naruto's understanding of combat and make him a more versatile ninja.
Well, Kakashi could train Naruto in combat skills specific to ANBU missions. This would include more lethal and precise attacks. He might also teach Naruto how to use different types of weapons that are common in ANBU operations. Maybe Kakashi would set up mock battles where Naruto has to face multiple opponents at once, just like in real ANBU scenarios.
Kakashi may become more empathetic. By constantly watching over Naruto, he gets to understand Naruto's struggles better, which could make him more in tune with his own emotions and those of others.
Kakashi's training style, which is often strict and methodical, would likely make Naruto more disciplined. Naruto is usually a bit of a wild card, but under Kakashi's tutelage, he would have to follow a set routine and be more precise in his actions.
It might lead to Kakashi taking on a more intensive training role for Naruto later. This could fast - track Naruto's growth in skills and power, changing the power dynamics in the story.
In some fanfictions, Kakashi might train Naruto by creating extremely challenging survival scenarios. For example, he could drop Naruto in a mock battlefield filled with various traps and enemies that Naruto has to overcome using his skills and wits. This forces Naruto to think on his feet and improve his combat abilities quickly.
When Naruto saves Kakashi, it often shows his growth in terms of leadership. He has to take charge of the situation, which is different from his earlier, more impulsive self. For example, if he has to organize a rescue mission, he learns to plan and delegate tasks to others.
Kakashi may become more fatherly. He starts to show more emotions and care, different from his usually aloof self in the original series.
