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.
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.
Kakashi might immediately offer a comforting presence. He could put his hand on Naruto's shoulder and just be there silently, letting Naruto know he's not alone.
One great fanfiction could be 'The Bond Beyond Teams' which focuses on the complex relationships between Kakashi, Naruto and Sasuke. It delves deep into how their individual growth affects their bond with each other. Another good one is 'Naruto's Unseen Path' where Sasuke and Kakashi play important roles in Naruto's journey to discover a new power. There are also fanfictions that explore alternate universes, like 'Parallel Konoha' where the three characters have different roles and personalities yet still maintain their core essence.
Well, Kakashi's adoption would likely bring more stability to their lives. He could train them more intensively and offer better guidance. Naruto might finally feel like he has a proper family, which could boost his self - confidence. Sasuke, on the other hand, could find a new sense of belonging and might be less likely to go down the dark path he did in the original story.
Well, Kakashi is a complex character. When he discovers Naruto is abused in the fanfiction, he may first feel a deep sense of guilt for not noticing earlier. He'd then use his skills and influence in the village. He could start by reporting it to the proper authorities in Konoha, like the Hokage. And at the same time, he'd be there for Naruto, providing emotional support, talking to him, and helping him through the trauma. Kakashi has his own past traumas, so he'd understand what Naruto is going through on some level.
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.
One possible plot could be that Naruto was on a mission alone and got ambushed by a group of rogue ninjas. Kakashi, while out on his own patrol, stumbles upon the injured Naruto. He quickly takes Naruto to a safe place and uses his medical ninjutsu to stabilize him. Then, he might start to investigate who attacked Naruto and why, leading to a revenge - based sub - plot or uncovering a larger conspiracy against Konoha.
Once Kakashi finds out Naruto is abused in the fanfiction, Naruto's life takes a turn for the better. Kakashi would become a more constant presence in his life. Naruto would no longer have to fear the abuse continuing. He'd be given a chance to focus on his growth as a ninja and as a person. Kakashi would introduce him to positive influences in the village, like wise elders or kind - hearted villagers. Naruto's self - image would improve as he realizes he is worthy of protection and care. His living situation might also change, perhaps moving to a more secure and comfortable place. And his dreams of becoming Hokage would seem more achievable as he overcomes the trauma of the abuse with Kakashi's help.
Power and its limits is another one. In these fanfictions, we see them constantly testing their powers. Naruto might be trying to master new jutsus without losing himself. Sasuke could be grappling with the power of his Sharingan and how far he should go with it. Kakashi, with his Sharingan and his own unique skills, also serves as an example of someone who has learned to control and use his power effectively within certain limits.
