Naruto could change Konoha by promoting unity. He might organize village - wide events where everyone, from the strongest jounin to the youngest genin, participates. This would strengthen the bonds between the villagers.
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.
Well, if Naruto becomes the 5th Hokage in fanfiction, he would surely bring a new energy to the village. He might start by reforming the ninja training system. Since he had a tough time growing up as an outcast, he'd make sure no kid in the village ever feels that way. He could also focus on better relations with other villages. Naruto's always been about peace and friendship, so he'd probably organize more joint ninja missions with other villages to build trust.
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.
It could be the First Hokage, Hashirama. Naruto would be amazed by his powerful Wood - Style jutsu and his ability to create the village. He could learn about the original ideals behind the Hidden Leaf from Hashirama.
I think the whole of Team 7 would be in full support. Sasuke might return to the village and support Naruto as he sees Naruto's growth and leadership potential. Kakashi would also be there to guide Naruto as he steps into the role. Additionally, the people of Konoha who have seen Naruto grow from an outcast to a hero would be very likely to support him as their new Hokage.
I don't think it's strange at all. Naruto is a very curious person. Fanfiction can offer new perspectives on his own life and the lives of his friends. He might learn something new about himself or get inspired by the creative ideas in the fanfiction. It could also be a form of entertainment for him during his downtime.
A Naruto x Hinata fanfiction could focus on a mission they go on together during Naruto Shippuden. They are forced to rely on each other in a dangerous situation. Hinata gets injured protecting Naruto, and Naruto is filled with a new - found determination to protect her. This experience deepens their bond, and Naruto starts to see Hinata in a whole new light, leading to the start of their romantic relationship.
Hinata would be an important character as Naruto's wife. She could support Naruto in his Hokage duties and also play a role in the social aspects of the village. Their children might also be part of the story, representing the new generation.
One interesting plotline could be Naruto facing new and unexpected threats to the village as Rokudaime Hokage. He might have to deal with political intrigue within the village as some may not fully accept his leadership at first.
