Another idea might be the origin of the hidden blades. It could be that they are an ancient weapon from a lost ninja clan that Naruto discovers. This discovery could lead to a whole new arc in the fanfiction where he has to learn about the history of the blades and their proper use.
Perhaps in this fanfiction, the hidden blades are not just normal weapons. They could be imbued with some sort of special chakra or magic. This would make them more powerful and give Naruto an edge in battles against stronger opponents like Pain or Madara.
One idea could be a story where the main character discovers a hidden blade with special powers that was lost during the Naruto era. This blade could have the ability to control certain elements in a unique way, leading to new battles and alliances.
One could be a story where Naruto discovers an ancient Kiba blade technique and uses it to defeat a powerful enemy. He might train in secret with the blades, surprising his friends during a battle.
It could be Orochimaru. He is always interested in new and powerful weapons. With Naruto having hidden blades, Orochimaru might see it as a threat and try to take the blades for himself, leading to a conflict.
In Naruto fanfiction, some blades might have unique powers. For example, a blade could be enchanted with the ability to cut through chakra barriers. It could also have a hidden power that is only unlocked when the wielder reaches a certain level of skill or emotional state.
One interesting idea could be exploring how the story would change if a major character's gender was different. For example, if Naruto was female, her relationships with Sasuke and Sakura might have different dynamics. Maybe she'd face different challenges in the ninja world as a female, like different expectations in combat or leadership.
Perhaps there's a blade - forging competition in the Hidden Leaf Village. Kiba enters with his own unique design for a blade, and Naruto is there to cheer him on. But then it turns out that there's some foul play involved by an opposing village. They then have to work together to expose the cheaters and prove Kiba's blade - making skills.
One idea could be a story about a new genin who has a unique and powerful bloodline that has been hidden in the village for generations. They struggle to control it while also trying to prove themselves worthy to their team.
Some interesting plot ideas in naruto hidden power fanfiction might include Naruto finding out he has a hidden power that lets him see the past and future of the ninja world. This could help him prevent disasters or find lost secrets. Another idea is that his hidden power is related to chakra absorption and manipulation in a unique way. He could absorb the chakra of his opponents and use it to enhance his own abilities or heal himself. Also, perhaps Naruto has a hidden power that is linked to the spirit world, allowing him to call upon the help of deceased ninja or gain spiritual guidance.
Perhaps a plot where a Hidden Cloud ninja forms an unlikely alliance with a ninja from another village to stop a powerful and evil organization that threatens all the ninja villages. They have to overcome their cultural differences and learn to trust each other in the process. This would involve lots of action scenes as they battle the minions of the evil organization and also some deep emotional moments as they understand each other's motives and values.
A really interesting plot could be a character who discovers they have a bloodline that is a combination of two powerful clans' abilities. This creates a unique set of powers that no one has seen before. The character then has to struggle with learning to control these powers while also facing the jealousy and fear of others in the ninja world who see them as a threat.
