Well, in this fanfiction, Naruto might attack the Kage Summit because he feels the Kages are making decisions that are unfair to the ninja world as a whole. For example, if they are planning something that could harm the smaller villages or his friends. The different Kages would then have to decide how to deal with Naruto. Some might want to capture him, while others might try to understand his motives first.
One possible plot point could be Naruto's reasons for attacking the Kage Summit. Maybe he's been misinformed or is trying to prove a point. Another could be the reactions of the various Kages, like how Tsunade might be conflicted because she knows Naruto.
Sasuke could be one to stop Naruto. They have a complex relationship and Sasuke might understand Naruto's motives and be able to talk him down.
Obviously Naruto would be one of the main characters as the title implies he's the one attacking. And the Kages, like Gaara, Tsunade, and the other village leaders would also be main characters since they are at the summit that Naruto is attacking.
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.
One idea could be a secret alliance formed during the Kage Summit that was not in the original story. Maybe a Kage has a hidden agenda and is secretly working with an enemy of the village. For example, the Mizukage could be in cahoots with a rogue ninja group to gain power over the other villages.
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 some naruto kage summit fanfiction, there might be a plot where a Kage is actually a spy for another village. This could lead to a lot of drama and political intrigue during the summit as secrets are revealed and trust is broken.
A plot could revolve around a mysterious threat that targets the Kages during the summit. It could be a long - forgotten enemy or a new dark force. The Kages have to put aside their differences and work together to face this threat. They might also discover some secrets about their own villages in the process of fighting this common enemy.
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.
The fanfiction might explore Dark Naruto's motives during the Kage Summit. He could be on a mission to expose the secrets that the Kages have been hiding from the shinobi world. His actions at the summit could be a way of shaking up the established order. For example, he might reveal a conspiracy among the Kages that has been affecting the balance of power in the ninja villages. This would not only put the Kages in a difficult position but also force the other shinobi present to re - evaluate their loyalty.
In this fanfiction, perhaps Naruto becoming a Kage before the summit means he has to face political challenges early on. He might have to deal with other villages' representatives who are skeptical of his young age and inexperience. He could use his unique ninja way and his strong bonds with his friends to win them over.
