If Naruto was Kakashi's age, he'd likely be a more jaded character. He'd have seen more of the cruel side of the ninja world, like Kakashi did. His skills would be more refined, and he might not have the same naive charm. His relationship with Sakura could be more of a comradeship based on mutual respect for their abilities rather than the one - sided crush situation in the original story. And his attitude towards the Hokage title might be different too, perhaps more cynical considering the politics and hardships he would have faced by that age.
Well, if Naruto were Kakashi's age, the story would be very different. Naruto would be much more experienced and perhaps less impulsive. He would have already gone through a lot of the traumas and growth that Kakashi had at his age. His relationships would also change. For example, his bond with Iruka might be more of an equal friendship rather than a student - teacher like relationship. Also, his rivalry with Sasuke would be on a different level, as they would both be more mature and their reasons for competing might be more complex.
If Naruto was the same age as Kakashi, his character development would take a different path. He would have likely faced different traumas and challenges growing up. For example, he might have been more directly involved in the Third Hokage's reign and the events that led to his death. This would have made him more politically aware and perhaps more cynical. Also, his relationships with his peers would be different. He might not have had the same close - knit group of friends as he does in the original story, as his age difference would put him in a different social circle.
Since Kakashi has his own set of friends and allies, Naruto would be exposed to a different social circle. This could lead to different relationships and interactions that shape his character. For example, he might have a closer relationship with Gai or Asuma in this fanfiction. Their influence, combined with Kakashi's parenting, would make Naruto more well - rounded and perhaps more in - tune with the overall shinobi community.
In this fanfiction, Naruto's character development would change significantly. With Kakashi as his adoptive father, Naruto would be exposed to different values. He would learn about teamwork in a different way. Kakashi's own experiences with his team could influence how Naruto views his comrades. Also, Naruto might be more introverted in some ways as he would spend a lot of time with Kakashi, who is not as outgoing as some other characters. His ninja skills would progress faster in some areas like stealth and intelligence - gathering because of Kakashi's expertise.
One possible plot could be that Naruto is already a respected ninja in the village. He's assigned to a special mission to deal with a new threat that's related to an old enemy of Kakashi's. Since he's at Kakashi's age, he has the skills and knowledge to handle complex situations. Along the way, he discovers secrets about his own past that are linked to this new threat. He has to use his experience and the bonds he's made over the years to overcome the challenges.
Well, for one, Kakashi's childhood might have been different. Naruto could have been there to support him after his father's death. Also, Naruto might have influenced Kakashi's attitude towards the Sharingan. He could have been more cautious about Kakashi using it, given its toll on the user.
Well, Naruto's character would be different in many ways. Firstly, he'd have a stronger sense of discipline. Kakashi would instill in him the importance of following rules and regulations in the shinobi world. His view of friendship might also be different. While he'd still value his friends, he might be more guarded initially, as Kakashi might teach him to be cautious. His relationship with the Hokage and the village elders would also be distinct. He might have more respect for their authority due to Kakashi's influence, but at the same time, he could be more critical of their decisions if he felt they were not in the best interest of the village, based on the knowledge and values Kakashi has imparted to him.
Naruto's character would likely be more reserved in some ways. Kakashi is a rather stoic and composed person, and his influence might make Naruto less brash. Instead of always charging headfirst into situations, he would think more. For example, in battles, he might analyze the situation like Kakashi does before acting.
His training would be more diverse. Kakashi would introduce him to advanced chakra control techniques and some of his secret jutsu training methods. Kurenai would focus on Naruto's mental strength in relation to genjutsu. So instead of just focusing on brute strength like in the original, Naruto would have a more balanced training regime.
However, Naruto also has a big heart. In the long run, he would probably try to find a way to save Kakashi or bring him back to the right side. He wouldn't give up on Kakashi easily, believing that there must be some underlying reason for his actions and that he can be redeemed.
Her fighting style might be more refined. Kakashi is a very technical fighter, so he would likely instill in her a sense of precision. Unlike the male Naruto who often relied on brute force in the beginning, she might start with more calculated moves. For example, she could be better at using kunai and shuriken with deadly accuracy from the start.
