I think Naruto. Even though he's not one of the original Hokages, as Sarada's father, he has a deep understanding of Sarada. He could give her the most practical advice on how to face challenges, both in terms of strength improvement and mental growth.
Shikamaru is another possibility. He is known for his strategic mind. As Hokage, he could use his intelligence to make wise decisions for the village. He may not have the brute strength of Naruto or Sasuke, but his ability to plan and analyze situations would be invaluable in leading Konoha.
Sure does! Naruto becomes Hokage after going through numerous battles and proving his worth. It's a well-earned title that showcases his dedication and the respect he gains from his peers and the village.
In some fanfictions, Sakura might become Hokage through her exceptional medical skills. She could save the life of an important figure during a major crisis, and as a result, gain the respect and support of the village to take on the role. For example, if she cured a widespread disease that was plaguing the Hidden Leaf.
One possible plot could be Naruto having to prove himself to the village elders. He might start by implementing new training programs for the younger ninjas, inspired by his own journey. He could also focus on improving relations with other villages, using his charisma and unique perspective as someone who was once an outcast.
Well, in such a fanfiction, perhaps there's a political conspiracy behind forcing Naruto to be Hokage. Maybe some hidden group wants to control him through the Hokage position. Naruto then has to not only deal with the responsibilities of being Hokage but also uncover the conspiracy. He'd be constantly at odds with the council who forced him into this role, trying to prove that he can do a good job on his own terms.
There are various types. Some might focus on Naruto's intense training and growth to earn the title. Others could involve unexpected challenges and how he overcomes them to become the Fifth Hokage.
