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.
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.
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.
Well, the story could develop in many ways. Maybe Naruto could be an orphan found by someone else in the village, like an old ninja who decides to train him in secret. This would change Naruto's backstory completely. He might not have the same kind of pressure or expectations that come with being the son of a famous Hokage. His character could grow in a different direction, perhaps being more independent from the start as he has to create his own identity without the shadow of his 'father' Minato.
I like 'The Day Naruto Found Minato'. In this fanfic, it starts with Naruto accidentally stumbling upon a time - travel jutsu that takes him to meet Minato in the past. It's really interesting to see how Naruto interacts with his father in that different time period. There's also 'Naruto and Minato: A New Bond' which explores the psychological aspects of their relationship, like how Naruto overcomes his initial disbelief and then starts to build a strong bond with Minato.
Yes, there are some 'naruto is kakashi's son' fanfictions out there. The Naruto fandom is quite creative and has various out - of - the - box ideas for fanfictions. These types of fanfictions often explore unique relationships and character developments that deviate from the original storyline.
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 reason could be that Naruto is feeling lonely. Despite having friends, there are times when his past as an orphan and the years of being shunned by the villagers resurfaces, making him feel isolated. Kakashi finding him in such a state might then lead to a heart - to - heart conversation about Naruto's inner struggles.
