Yes, in some fanfictions, Naruto is depicted as the First Hokage's reincarnation. This often adds an interesting twist to the story, as it can bring in new relationships and powers related to the First Hokage's legacy.
I'm not sure specifically as there could be many interpretations. It might be a story where the character Harry from the Harry Potter universe is somehow related to being the first Hokage from Naruto. Maybe it's a crossover fic that combines the magic of Harry Potter with the ninja world of Naruto in a really unique way.
Obviously, Harry would be one of the main characters as the title implies he is the first Hokage. There might also be characters from the Naruto world like some of the original ninja clans' leaders who would interact with Harry. Maybe Naruto's ancestors could be in the story as well.
Naruto would probably first assess the damage to the village. He would send out teams to check on the injured and start the process of getting the necessary supplies for the repairs. Then, he would call a meeting with the village council to discuss security measures to prevent future attacks like Pain's. He'd want to make sure that the village is well - defended and that they have a proper warning system in place.
Well, Naruto would probably become extremely powerful. The First Hokage had some unique abilities like his Wood Style. Naruto could learn a whole new set of skills and jutsus. He might also gain a different perspective on leadership and the history of the Hidden Leaf. It could change the way he approaches battles and his relationships with other villages too.
A major consequence is how other characters react. The village elders might treat him differently, perhaps with more reverence or more suspicion. Also, his enemies might see him as an even greater threat. Naruto himself might also feel a greater sense of responsibility towards the village, as he is now connected to its founder in a very special way. This could lead to him making different decisions in battles and in the overall story arc.
In this fanfiction, Naruto might learn a lot from the First Hokage. Maybe the First Hokage would teach Naruto some long - lost jutsu. For example, he could show Naruto how to use some ancient earth - style techniques that were powerful but forgotten over time. And Naruto could also ask the First Hokage about the origin of the village, getting a first - hand account of how Konoha was founded.
The First Hokage is obviously the main character. But we may also see other important figures like his contemporaries, who were also involved in the establishment of the Hidden Leaf Village.
In such a fanfiction scenario, it could be really exciting. Maybe they would be proud of Naruto. The First Hokage, Hashirama, might be impressed by Naruto's tenacity and his ability to bring people together like he did with the villages. Tobirama could see Naruto's growth in ninja skills and give him some tough - love advice. Hiruzen would be glad to see how Naruto overcame all the hardships he faced in the village. And Minato would finally have a proper father - son reunion and share his own experiences and wisdom with Naruto.
Perhaps a perk is the ability to shape the future of the ninja world. As Hokage, one can inspire the younger generation of ninjas. They can create new ninja academies or training programs. They also have the power to pardon or punish ninjas according to their deeds, which helps in maintaining law and order in the village.
