Some fanfics introduce an original villain who specifically targets Naruto during his training. This villain has a personal vendetta against Naruto or the idea of him becoming Hokage. They might have a new and dangerous jutsu that Naruto has to figure out how to counter. These villains often have complex backstories that make them more than just a one - dimensional bad guy and add depth to the fanfic.
One common plot twist could be that Naruto discovers a new and powerful chakra source during his training. For example, he might find an ancient scroll that reveals a unique form of chakra that no one has seen before. This new power could either help him greatly in his journey to become Hokage or bring unexpected challenges as others may try to steal it from him. Another plot twist could be that a former enemy turns out to be an ally and offers to train Naruto in a special technique. This changes the dynamics of his training and relationships in the story.
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.
There could be a focus on Naruto learning new forms of the Rasengan. Hokage Naruto, with his vast experience, could teach Naruto different ways to infuse the Rasengan with other elements more easily. Maybe Naruto would learn how to quickly switch between a Fire - Rasengan and a Wind - Rasengan during combat.
One possible thing that could happen is that Naruto could teach his younger self some advanced jutsu. For example, he might show the younger Naruto how to better control the Nine - Tails' chakra earlier. This would give the younger Naruto a significant power boost and change the way he approaches battles in his early days.
Perhaps he would focus on his training and become a master of a new, unique form of jutsu. He might then open a dojo to teach the younger generation his skills, rather than aiming for the Hokage position. This way, he could still have a great influence on the ninja world.
The training could speed up the younger Naruto's growth. He would become stronger and more skilled faster, which might lead to different outcomes in battles. For instance, he could defeat enemies more quickly and with less damage to himself and the village.
In some fanfictions, the Hokage trains Naruto in the art of sealing techniques. Since Naruto has the Nine - Tails, learning about sealing could be crucial for him to better manage its power or even use it in new ways. For instance, the Hokage could teach Naruto how to create seals that can store and release chakra in a more efficient way. Another aspect could be the Hokage training Naruto in espionage. Naruto would learn how to gather information secretly, which is an important skill for a ninja. This could involve disguises, infiltration techniques, and how to read body language to detect lies.
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.
