It could be Naruto himself. Since he has a connection to all the villages in some way, he could play a crucial role in the fanfic, perhaps as a mediator or someone who uncovers a hidden conspiracy during the summit.
Perhaps in the fanfic, a young shinobi manages to infiltrate the Five Kage Summit and has a significant impact on the discussions. This shinobi could bring new ideas or warnings that change the course of the kages' decisions. For example, he might have uncovered a plot by a rogue ninja group to take advantage of the kages being gathered in one place. This would not only create tension between the kages and the external threat but also among the kages themselves as they debate how to handle this unexpected situation.
In this fanfiction, Naruto might be pushed to attack the Five Kage Summit due to some misinformation or a threat he perceives to Konoha. Maybe he thinks the Kages are planning something against his village.
It could be a rogue ninja who has a vendetta against all the villages represented at the summit. He might have been wronged in the past by the combined actions of the five great villages and now seeks revenge. He could use the chaos of the summit to launch attacks and try to undermine the stability of the shinobi world.
In a 'naruto five kage summit fanfiction', a great plot could be that the Mizukage reveals she has evidence of a traitor among the other Kages' entourages. This leads to a tense investigation during the summit, with accusations flying and old grudges resurfacing. The story could explore how the Kages balance their trust in their own people and the need to maintain diplomatic relations during such a crisis.
In fanfiction, if Naruto ate the Kage Kage no Mi, he would gain the power to control shadows. This could make his combat abilities extremely powerful. He could use shadows to trap enemies, create illusions using shadows, or even use the shadows to enhance his speed and stealth in battles. For example, he could send his shadow to scout ahead unnoticed.
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.
