It would change a lot. Firstly, the whole dynamic between Naruto and Kakashi would be completely different. Instead of a mentor - student bond, it would be a father - son one. Naruto's influence on Kakashi's upbringing would have to be reimagined. Also, the backstories related to Kakashi's family, like his relationship with his father Sakumo, would need to be adjusted to fit this new family tree. It would be a huge rewrite of the character relationships.
In some fanfictions, yes, Kakashi can be written as Naruto's dad. Fanfiction allows for creative and often non - canonical interpretations of relationships. Writers might create this relationship to explore different character dynamics and storylines that deviate from the original Naruto plot.
One reason could be to create a new and unexpected dynamic. It shakes up the familiar relationships from the original Naruto story. Another reason might be to explore how Kakashi's character would develop in a fatherly role, which is very different from his role as a mentor in the original.
The story would change a great deal. Naruto's presence in Kakashi's generation could mean an earlier end to the Third Great Ninja War. His ability to inspire and his combat skills could turn the tides of battles. For instance, if he was there during the Kannabi Bridge mission, things might have gone very differently. He could have kept Obito from getting crushed and perhaps changed the fates of many.
The story would change significantly. Naruto might grow up with a different set of values. Kakashi's influence could make Naruto more strategic in his battles from a young age. Instead of the wild and often improvised fighting style, he might have a more calculated approach. Also, Naruto's social status could be different. With Kakashi as his father, he might be more respected in the village earlier on, but also face higher expectations.
Naruto's training would be more personalized. Instead of the general training he received in the academy, Kakashi would tailor his training to Naruto's strengths and weaknesses. Given Kakashi's knowledge of different ninja arts, he could expose Naruto to elements of different clans' techniques. This would make Naruto a more versatile ninja. Kakashi would also likely push Naruto to think more analytically during combat, rather than relying solely on brute force. This would help Naruto become a more well - rounded and formidable ninja in the long run.
Since Naruto has more knowledge of the future, Kakashi might start to rely on him more, which could shift their relationship. Naruto could also see a different side of Kakashi from the past, and this new understanding could deepen their connection. For example, they might have to face some challenges together that make them trust each other more than before.
Kakashi's training style, which is often strict and methodical, would likely make Naruto more disciplined. Naruto is usually a bit of a wild card, but under Kakashi's tutelage, he would have to follow a set routine and be more precise in his actions.
It could become strained. Naruto snapping at Kakashi would create an initial rift between them. Kakashi might be taken aback by Naruto's outburst and Naruto, after snapping, might feel a bit guilty but also stubborn about his feelings, which would make the relationship tense for a while.
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.
He might become more patient. As a dad, he has to deal with his kids' tantrums and mistakes, so patience is key.
