Such a situation would likely cause a lot of internal conflict for Naruto. He might become more rebellious or withdrawn, and it could have a domino effect on the entire ninja village and its missions.
Well, it could lead to a major rift in their relationship and affect the dynamics of the team.
In this alternate scenario, it could lead to a lot of tension and conflict within the team. Naruto might be less inclined to follow Kakashi's lead and could even try to train on his own, causing problems for the group's dynamics.
One possible reason could be that Naruto might feel Kakashi is too strict with his training. Maybe Kakashi's methods are too harsh for Naruto, making him frustrated and gradually developing dislike.
Maybe Kakashi is preoccupied with other important missions. He is a highly - skilled and often - needed ninja. There could be some top - secret missions that require his full attention, leaving him no time to train Naruto properly.
If Naruto imitates Kakashi in a fanfiction, one aspect could be his appearance. Naruto could start wearing a mask like Kakashi does. He might also try to copy Kakashi's spiky white hair by using some sort of hair product or a transformation jutsu. In terms of behavior, Naruto might attempt to be as calm and collected as Kakashi in battle. However, Naruto's natural exuberance would likely break through at some point. He could also try to imitate Kakashi's habit of arriving late, which would be quite a change for Naruto who is usually very punctual when it comes to important things like missions or training with his friends.
One possible reason could be that Kakashi might think Naruto is not ready yet. Maybe Naruto hasn't mastered some basic skills that are prerequisites for the more advanced training Kakashi has in mind. Another reason could be that Kakashi is worried about Naruto's recklessness. Naruto has a tendency to rush into things without thinking, and Kakashi might fear that this could lead to Naruto getting seriously injured during the training.
One possible reason could be that in the fanfiction, Kakashi might have made a decision during a mission that Naruto strongly disagreed with. For example, Kakashi could have chosen to sacrifice something important to Naruto in order to achieve the overall mission objective.
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.
Communication is key. If they sit down and talk about their misunderstandings and feelings, it could start to mend their relationship. Naruto could express his frustrations, and Kakashi could explain his actions.
In the fanfiction, Kakashi might train Naruto in teamwork. Even though Naruto is often a solo fighter, Kakashi could show him the importance of working with others. He could arrange mock battles where Naruto has to team up with other characters, like Sakura or Shikamaru, and learn how to coordinate their attacks and defenses.
In many Naruto fanfictions about Kakashi training Naruto, Kakashi might push Naruto to new limits. He could focus on Naruto's Rasengan training, making it more powerful or teaching him new variations. For example, Kakashi might introduce elements to the Rasengan, like wind or lightning, to enhance its destructive power. This kind of training would not only strengthen Naruto physically but also help him understand chakra better.
