One idea could be a character from the Naruto universe obtaining the Kage Kage no Mi. They could use its powers to create shadow clones with unique abilities that are different from the normal shadow clones in Naruto. For example, these clones could have the power to manipulate shadows in ways not seen before, like using them to create illusions or even solidify shadows into weapons.
The Kage Kage no Mi's power can be used to disrupt the normal combat styles in Naruto. For instance, most ninjas rely on hand - to - hand combat, ninjutsu, and genjutsu. But with the ability to create and control shadows, a character can bypass these traditional defenses. They can use shadows to immobilize opponents or even drain their chakra, which would completely change how battles are fought and thus the power dynamics in the Naruto fanfiction world.
There are many great Kage Naruto fanfictions out there. Some might explore Naruto's relationships with other Kages from different villages in a more in - depth way. For instance, his interactions with Gaara, who is also a Kage. In these fanfictions, they could be working together on some grand project for the betterment of all the ninja villages. Additionally, some fanfictions might show Naruto's struggle to maintain his ideals as a Kage in a world that still has a lot of underlying tensions and power struggles.
One idea could be exploring the backstories of the kages in more depth. For example, how did the Third Hokage really come to power? Another could be a what - if scenario where a different ninja becomes a kage earlier than in the original story. Maybe Rock Lee could become a kage through his sheer determination and unique fighting style.
In such a fanfic, the plot might involve Naruto getting special and intense training from one of the Kage. For example, if trained by the Hokage, he could learn unique jutsu that are only known to the village leader. This would significantly boost his power and make him a more formidable ninja in a short time.
