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.
One common theme is redemption. Since Kakashi can go back in time, he often tries to make up for past mistakes or prevent tragedies that occurred in the original timeline. For example, he might try to save a character who died before. Another theme is the changing of fates. He can change the destiny of not only himself but also of his friends and the whole village. He can use his knowledge of future events to better prepare for threats.
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.
One possibility is that there would be a lot of reminiscing. Team Minato was Kakashi's old team. They might talk about old missions, like the one where they faced the Stone ninjas. Kakashi could share how their teachings influenced his leadership as Hokage.
Emotionally, it would be a powerful encounter. They might share their feelings about the losses they've all faced, like the death of Minato. This could strengthen their relationships and also give Kakashi new insights as Hokage on how to protect the village better.
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.
A cool plot would be Kakashi traveling back to a time during one of the great ninja wars, say the Third Great Ninja War. He could use his knowledge of future jutsu and strategies to turn the tides of battles that were previously lost. He might also be able to save comrades who died in the original timeline, and in the process, change the future of many ninja families.
