One interesting storyline could be a Kage - level ninja from a minor village rising to prominence. For example, a ninja from the Hidden Rain Village who has unique water - based jutsu that no one has seen before. He could start by taking on small missions within his village but then gets noticed by other Kages during a joint mission. This ninja then has to navigate the politics among the different villages while also trying to prove himself as a worthy Kage - level combatant.
Definitely Naruto Uzumaki. Since he becomes the Hokage in the original series, he is often a central figure in fanfiction. His growth from a young, mischievous ninja to a powerful Hokage gives a lot of room for creative storylines in fanfiction. Writers can explore his relationships with other villages' leaders, his family life, and his new jutsu development as a Kage - level ninja.
One interesting 'kage level naruto fanfiction' could be about Naruto facing a new and powerful enemy that even the kage struggle to defeat. It might involve him having to use his kage - level skills in new and creative ways. For example, he could combine his shadow clone jutsu with some new space - time ninjutsu he discovers. Another could be a story where all the kage from different villages team up with Naruto to take on a common threat that endangers the entire ninja world. This would show a great display of different kage - level powers working together.
Some fanfictions might explore the personal lives of Kage - level shinobi. For instance, a story about a Kage - level shinobi who is also a single parent trying to balance their duties towards the village and raising their child. Or it could be about the love life of a Kage - level shinobi, how they deal with relationships while being in such a high - profile and dangerous position in the ninja world.
An interesting aspect could be the interaction between the genin and the kages during the exams. The kages could be seen as both mentors and intimidating figures. They might give the genin cryptic advice that the genin have to figure out in order to progress in the exams. And the genin, in turn, could surprise the kages with their creativity and determination. This back - and - forth relationship would make for a very engaging fanfiction.
One possible scenario in this fanfiction could be that the Chunin Exams are made even more challenging with kage - level tasks. For example, instead of just fighting among genin, they might have to face off against kage - level illusions or strategize against kage - level opponents' battle plans. This would test the genin's ability to think on a much higher level.
One idea could be a story where a new, unknown shinobi suddenly shows kage - level skills and challenges the existing kage system. This shinobi might have a unique power that the current kage have to figure out how to deal with.
One idea could be a Kage - level character like Naruto traveling back in time to the founding of the Hidden Villages. He could use his knowledge of the future to prevent some of the early conflicts and shape the villages in a more positive way. For example, he might stop the Uchiha - Senju feud from escalating as it did in the original timeline.
A plot could be that the genin is an experiment of Orochimaru. Orochimaru has been secretly working on a project to create a genin with kage - level abilities. The genin manages to break free from Orochimaru's control but still has these extraordinary powers. The genin then has to find a way to use these powers for good while also dealing with the fact that Orochimaru might be after them again to either get them back or eliminate them to cover up his experiment.
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.
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.
