If Naruto was the same age as Kakashi, the power dynamics would be very different. Naruto might be more skilled and mature from the start. He could have been part of the earlier battles against the Akatsuki. Also, his relationship with Sasuke might have a different flavor as they would be closer in age and experience. For example, they might be more like equals in their rivalry, rather than Naruto constantly chasing Sasuke's level of skill.
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.
If the protagonist of Naruto was the same age as Kakashi, they might have met when they were young and attended the ninja school training together. As time passed, they might grow up together and meet under some opportunity to start a thrilling story.
In a more light - hearted plot, Fem Naruto and Kakashi could start a friendly prank war in the village. Since they are the same age, they might have a similar sense of humor. This could lead to some hilarious situations where they constantly try to out - prank each other, but also learn important lessons about friendship and respect in the process.
A great fanfic concept could be a story where Fem Naruto and Kakashi are rivals instead of comrades. With their equal age, they might compete for recognition, for example, in the academy. This could lead to some intense battles and also a slow - burn realization of their mutual respect for each other's skills.
One possible scenario could be that Naruto and Mikoto grow up together in a different Konoha. They might become friends and train together. Naruto could learn a lot from Mikoto, who is from the Uchiha clan and has her own unique skills. Maybe they would be in the same class at the ninja academy, and Naruto's positive attitude would influence Mikoto as well.
Well, they could become rivals. Since Naruto is always striving to be the best and Mikoto, being from the Uchiha clan, would also be highly competitive. They might compete in various ninja tasks and exams, constantly pushing each other to improve.
One possible plot could be a story where Naruto and Kushina grow up together in a different timeline. They could face the challenges of the ninja world side by side. Maybe they'd train together under Minato and form a unique bond that's different from the usual mother - son relationship. This could lead to them having adventures and making friends together, and their combined skills might change the course of some of the events in the Naruto universe.
The story would be transformed in many ways. Naruto, being as old as Itachi, would have had different training experiences. He might have been trained by different people or in different ways. This would lead to different jutsu and abilities. In the political arena, Naruto could have played a more active role in preventing the Uchiha - Leaf Village rift. His relationship with characters like Kakashi and Jiraiya would also be different. For instance, he might have been more of an equal to Kakashi, and Jiraiya might have had different expectations of him. All these changes would create a whole new narrative for the Naruto story.
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.
