Jealousy could be a factor in some fanfiction. Maybe there's a new student who is getting all the attention, and Sasuke is being a bit too cocky about his abilities. Kakashi, in a moment of weakness, lashes out at Sasuke to teach him a lesson about humility. However, this would be a very different take on Kakashi's character compared to the original series.
It could be for Sasuke's own good. Kakashi might think that by hurting Sasuke physically in a controlled way, like in a very tough training, he can make Sasuke stronger and more resilient. He could be trying to prepare Sasuke for the harsh realities of the ninja world.
There might be a prophecy or some sort of dark omen. Kakashi might believe that by hurting Sasuke at a certain point, he can prevent a greater evil from befalling Sasuke or the village. So, he takes the difficult decision to cause harm to Sasuke, even though it goes against his normal teachings.
Kakashi would likely be very concerned. He would immediately assess Naruto's injuries. If they were serious, he would use his medical skills to start treating him right away. His first reaction would be to make sure Naruto was stable and out of immediate danger.
It would be very close. Kakashi would be like a father or an older brother to them. Naruto and Sasuke would respect and rely on him. They would probably have a more harmonious relationship with each other too, because Kakashi would be there to mediate any conflicts.
Well, often in Hurt Kakashi fanfiction, there's the theme of his physical injuries and how he copes with them. Given his dangerous line of work as a ninja, he gets hurt a lot. Writers might explore how he deals with long - term or serious injuries that could potentially end his ninja career. Also, his relationships can be a source of pain. For instance, his complex relationship with Obito and how that affects his mental state when they are at odds.
Often, Gai is paired with Kakashi in Hurt Kakashi fanfiction. Gai, with his unwavering belief in friendship and his eternal rivalry with Kakashi, can be a great character to interact with a hurt Kakashi. He might try to pull Kakashi out of his slump through their friendly competition. Also, Rin is sometimes included. Since she has a significant past with Kakashi, her presence in the fanfiction can either be a source of comfort or more pain, depending on how the story is written.
Well, it would be extremely unorthodox. It might involve some sort of magical or alternate - universe element to make the pregnancy possible. Maybe there's a powerful jutsu that messes with biology. The story could then focus on how Kakashi and Sasuke deal with this unexpected situation, their reactions, and how it affects their relationship.
He'd probably be a mix of angry and sad. Angry at whoever or whatever caused Naruto to be in this state, and sad because he cares about Naruto so much. He might clench his fists tightly, trying to control his emotions while he focuses on helping Naruto. He'd also feel a sense of guilt, wondering if he could have prevented this from happening.
Well, in fanfiction, Kakashi might seem to favor Sasuke because Sasuke is extremely talented. He has a natural aptitude for jutsu and a strong drive for power. Kakashi, being a great ninja himself, would recognize this potential and be more drawn to mentoring Sasuke to help him reach his full potential.
The fanfiction would likely show a different side of their development. Since Kakashi is a very experienced ninja, he could expose Naruto and Sasuke to different types of missions earlier. This would accelerate their growth not only in terms of combat skills but also in terms of understanding the ninja world. And with Kakashi as their adoptive father - figure, they would have a stronger emotional support system, which could potentially prevent some of the tragedies that happened in the original story.
Yes, there might be some fanfictions out there with such an unusual plot. However, it may not be a very common or mainstream concept in the fanfiction community. Fanfiction often explores creative and sometimes out - of - the - box ideas, and this would be one of them.
Maybe Naruto is short on money for some delicious ramen and thinks Kakashi might have some spare change. After all, Kakashi always seems to have some mystery about him and Naruto might assume he has some cash hidden away.
