Another plot could be a time - travel fanfic where Naruto and his friends are sent back in time to the events that led to the Land of Waves' situation in the first place. They then have to figure out how to change things for the better without changing the future too much.
You could also write a fanfic about the lives of the ordinary people in the Land of Waves during and after Naruto's visit. How did their lives change? What impact did Naruto's heroics have on the day - to - day existence of the villagers? This could explore the more human and social side of the story.
Perhaps a fanfiction could focus on how the events in the Land of Waves affected the economy and the daily lives of the people there. Naruto could witness the struggles of the villagers and come up with a plan to help them, using his unique perspective as an outsider. This would not only show his growth as a character but also give a different view of the Land of Waves.
One idea could be Naruto getting lost in the Land of Snow and having to team up with local shinobi to find his way back. He could learn about their unique ice - based jutsus during the adventure.
A plot could revolve around a new villain emerging from the Land of Demons. This villain has a special connection to Naruto's past, and Naruto must face his own inner demons as well as the external threat to save the Land of Demons and his own world. The story could explore themes of redemption and self - discovery.
One idea could be exploring the lost history and secrets of the Land of Whirlpool. Maybe the main character discovers an ancient jutsu that was once unique to the land. Another could be a story about a character trying to revive the glory of the Land of Whirlpool after it has been in decline.
An interesting plot idea for Naruto fanfic might be to focus on the life of a minor character. For instance, what if we told the story of a genin who never made it to be a chunin but still had a significant impact on the village in some other way? Or a story where all the ninja abilities are suddenly switched among the characters, and they have to adapt to these new powers while still facing their usual enemies. This could lead to some really fun and unexpected character interactions.
The feudal lord could be secretly training as a ninja himself. He wants to better understand the world of the ninja and be able to protect himself without relying solely on his guards. This would add an element of mystery as he has to keep it a secret from his court.
A young girl who is an expert in water - based ninjutsu but was self - taught because she had no proper teacher in the Land of Waves. She could join Naruto's team temporarily and teach them some unique water - related techniques.
You could write about how the relationships between characters change in this new land. For example, Naruto and Sasuke might have a different dynamic as they face new challenges together. Also, new characters native to the New Land could be introduced, with their own unique cultures and abilities that interact with the existing Naruto world in interesting ways.
Perhaps a fanfiction where a group of humans from our world accidentally get transported to the land of the giants. They have to quickly learn how to survive and communicate with the giants, while also trying to find a way back home. They could form alliances with some of the more friendly giants and face off against the hostile ones.
One idea could be that Naruto discovers a hidden power within Shenron. For example, instead of just granting wishes in the traditional way, Shenron could offer Naruto a special training regime that enhances his already powerful jutsu. This could lead to Naruto facing new and even stronger enemies.
