If they were brothers in fanfiction, their relationship would become much more complex and multi - faceted. Kakashi, being the older brother, would feel a great sense of responsibility for Naruto. He would not only guide Naruto in his ninja training but also in his personal growth. Naruto, on the other hand, would look up to Kakashi not just as a powerful ninja but as his big brother. They would have inside jokes and a unique way of communicating that only siblings have. In times of trouble, they would rely on each other more instinctively. Their relationship would also have an impact on how others in the village view them. Some might envy their close bond, while others might respect them more for their family connection.
Their relationship makes their missions more collaborative. They trust each other completely. So, instead of following a strict hierarchical structure like in the normal ninja teams, they work as equals. This means they can make decisions faster and adapt to unexpected situations more easily.
At first, it might be a bit rocky. Harry, being a Gryffindor, and Blaise, a Slytherin, have different outlooks. But as brothers, they'd gradually start to understand each other more. They'd probably become protective of one another and support each other in the face of danger.
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.
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.
They would become more united as they are co - parenting. They would have to communicate more often about the child's upbringing, training, and future. Their relationship would likely become deeper and more complex as they share the joys and challenges of raising a child.
Their relationship would likely become very close. Naruto would probably start to see Kakashi as a father figure. Kakashi, in turn, would become more protective of Naruto.
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.
The relationship would become more complex. If Naruto time - travels, he might see Kakashi in a different light, as someone who was once young and inexperienced. Kakashi, on the other hand, would be intrigued by this strange kid with such advanced skills. They could become closer as friends, with Naruto sharing his future experiences and Kakashi guiding Naruto in the past world.
At first, Naruto might be a bit confused about this new arrangement. But Kakashi would use his easy - going nature to break the ice. He'd take Naruto for walks and talk about ninjutsu casually. Kurenai would be the one to make sure Naruto is well - fed and taken care of. As Naruto grows, he'd start to participate in their conversations more. He'd ask Kakashi for advice on tough missions and Kurenai for advice on how to deal with his friends. Their relationship would be a mix of mentorship, friendship and family, evolving as Naruto becomes more mature and skilled as a ninja.
At first, it might be awkward. Kakashi is used to being a mentor figure, and now he's in a position of being 'adopted'. But as time passes, Naruto's positive energy starts to rub off on Kakashi. Kakashi becomes more carefree and starts to enjoy life more, like Naruto does.
