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 some fanfictions, Naruto might face unique challenges right after becoming Hokage. For example, he could have to deal with a new, powerful enemy that targets the village because of his new position.
One reason could be that there are political forces against him. Maybe some of the elders in the village don't trust his unorthodox ways and fear he'll bring too much change. Another could be that there are other candidates who seem more suitable on the surface, perhaps someone with a more traditional shinobi background who doesn't have Naruto's wild streak.
Sakura is often a common side character. She could be helping Naruto in medical aspects, as she is a skilled medical ninja. Her relationship with Naruto might also be explored further, perhaps as a close friend and advisor.
Another plot might involve Naruto's relationships as Hokage. He could be mentoring a new generation of ninjas, like teaching them the true meaning of being a ninja. His own experiences as an outcast turned hero could shape his mentorship style. Also, his relationships with his old friends might change as he takes on the responsibilities of the Hokage, adding an interesting dynamic to the story.
Obviously Naruto himself is the central character. His friends like Sasuke often play important roles too. Sasuke might be there to support Naruto or sometimes challenge his decisions as Hokage.
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.
His friends like Sakura and Shikamaru would surely support him. Sakura, with her medical skills, could be an important part of his regime, providing healthcare for the ninjas. Shikamaru, being intelligent, could offer strategic advice. Also, the younger generation of ninjas who have been inspired by Naruto would be his strong supporters, as they believe in his leadership and the new direction he could take the village in.
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.
