Well, it depends on the specific fanfiction. Some fanfictions might explore alternate storylines where Naruto doesn't become the Hokage at all. Maybe he decides to pursue a different path in life, like focusing on being a teacher or an explorer. However, in a large number of fanfictions, he does achieve his goal of becoming the Hokage because it's such an iconic and desired outcome for fans who want to see his journey to the top in different ways.
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.
Sasuke could be an alternative. He has strong ninja skills and a deep understanding of the ninja world. His experiences have made him grow into a very capable person, and his Sharingan gives him an edge in combat and strategic planning.
In this fanfiction, Hokage Naruto might take Naruto to a special training ground. There, he could teach Naruto some of his own unique jutsu combinations. For example, he could show Naruto how to combine the Rasengan with his Sage Mode more effectively. This would give Naruto a huge power boost and also make him more confident in battles against tougher opponents.
Well, it would change a great deal. Firstly, Naruto's ideals as a revived First Hokage would likely influence Konoha in a different way. He might introduce more of Hashirama's original ideas that have been lost over time. For example, his approach to relations with other villages could be more like Hashirama's, which was more about peace and cooperation at the very start. This could lead to a quicker resolution of conflicts. Also, Naruto would have the wisdom of the First Hokage, which could make him even more formidable in battles and in political situations within the village. And his relationships with the other characters would also shift, as they would see him in a new light, perhaps with more respect due to his connection to the founding of Konoha.
Perhaps Naruto has developed a special chakra - based concealment technique. This technique would not only hide his physical identity but also any chakra signatures or auras associated with the Hokage position. He might use it when he is out and about in the village, so that even the most perceptive ninja wouldn't suspect that he is the Hokage.
There might be a storyline where the First Hokage appears in Naruto's dreams. In these dreams, they communicate and the First Hokage gives Naruto clues on how to solve some of the current problems in Konoha, such as political unrest or a new threat emerging from the shadows. Naruto then has to figure out how to use these clues in the real world.
One major challenge would be living up to the legacy of the original First Hokage. Everyone would have high expectations of him. Another challenge could be dealing with the political aspects of being in such a high - ranking position. He's used to being more of an out - of - the - box hero, not a traditional leader. Also, he might face resistance from some of the older clans in Konoha who have their own ideas about how the village should be run. And he would need to balance his new role with his relationships with his friends, who might see him differently now.
We can expect to learn about the origin of the Hidden Leaf Village. The First Hokage played a crucial role in its foundation. His story might include how he developed the village's ninja system and his relationships with other powerful ninjas at that time.
