Kakashi may also get angry. Angry at the people or things that caused Naruto to get those scars. This anger could fuel his determination to make Naruto stronger, so that he can better defend himself in the future. He might then intensify Naruto's training, all while having a new - found sense of protectiveness towards Naruto.
The plot might involve Naruto crying due to a misunderstanding with his friends. Kakashi witnesses this and steps in to mediate. He first calms Naruto down and then arranges for Naruto and his friends to have an open conversation. During this process, Kakashi shares some wisdom about friendship and communication, helping them resolve their differences.
His training and newfound knowledge play a role too. He could discover ancient ninja scrolls or be trained by a hermit. This might lead to him learning new jutsus or improving his existing ones. For example, he could master a more powerful form of the Chidori that can cut through almost anything. Also, his physical strength and speed could be increased through special training regimens.
Kakashi might be initially surprised. But then, he would probably use it as a teaching moment for Naruto. He could say something like 'Naruto, stealing is not the way of a ninja.' And then give him a punishment like extra training.
Well, it's popular because both Naruto and Kakashi are beloved characters. People like to see their relationship explored deeper. Kakashi is a respected and skilled ninja, and when he shows favoritism towards Naruto, it gives Naruto a boost that fans enjoy seeing. It's like a 'chosen one' kind of story within the Naruto universe.
One good 'strong naruto kakashi favoritism' fanfiction could be 'Naruto's Hidden Strength Under Kakashi's Guidance'. In this fic, Naruto is shown to have extraordinary growth under Kakashi's special training and mentorship. Kakashi focuses a great deal on Naruto, believing in his potential more than others, which leads to Naruto achieving great power early on.
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.
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.
Well, it could strain their relationship. Avoidance usually creates distance, and in this case, Kakashi might feel hurt or confused as to why Naruto is avoiding him.
Their relationship is like a mentor - mentee bond. Kakashi has trained Naruto, and when he sees Naruto achieve great things, it can be overwhelming. For example, when Naruto masters a new jutsu that Kakashi thought was difficult for him, Kakashi might cry out of joy for Naruto's accomplishment.
