Sasuke could be a great addition. He could be a rival to Naruto even at a young age, and Kakashi would have to deal with their constant bickering. His brooding nature would add an interesting dynamic to the story.
One common theme is mentorship. Kakashi being the experienced ninja guiding Naruto in his growth. Another theme is friendship. Despite the age and experience gap, they form a strong bond. For instance, they might have heart - to - heart conversations where Kakashi gives Naruto life lessons.
One popular 'kakashi and little naruto fanfiction' could be about Kakashi training Naruto in some unique ways. For example, Kakashi takes Naruto to a special place in the forest for a new type of chakra control training. They face some challenges during the process, like dealing with some tricky genjutsu that Naruto accidentally triggers. This type of fanfiction often focuses on the bond between them as teacher and student, and how Naruto grows under Kakashi's guidance.
One idea could be that little Naruto gets lost in the forest and Kakashi has to find him. Along the way, Kakashi discovers Naruto's secret hiding place filled with his dreams and wishes written on little scrolls.
Well, there could be. Fanfiction writers love to explore unique and unexpected relationships. Since Naruto and Kakashi are both popular characters in the Naruto universe, some writers might come up with such a plot for the sake of creativity and exploring different storylines. But it's not a part of the official Naruto story.
One major plot point is the adjustment of their relationship. Naruto might initially be shocked or overjoyed to find out Kakashi is his brother. Then they have to figure out how to act around each other. Another plot point could be the impact on their respective goals. Naruto's goal of becoming Hokage might be influenced by having Kakashi as his brother, and Kakashi's role in the village and his own personal missions could also change due to this new family connection.
Sasuke could be a popular character. He might be involved in the story in a way that either helps or hinders the situation where Naruto hurts Kakashi. For example, if Sasuke tries to stop Naruto from doing something stupid that would hurt Kakashi.
Another reason could be related to Kakashi's past actions. If there are some secrets or things Kakashi did in the past that come to light and Naruto doesn't like them, he could snap at Kakashi. Naruto has a strong sense of justice and loyalty, so if he feels betrayed or misled by Kakashi, his reaction could be to snap.
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.
One possible reason could be that Kakashi is preoccupied with other important matters in the village. Maybe he has some top - secret missions or tasks assigned by the Hokage that demand his full attention, leaving him with little time to focus on Naruto.
