A plot could involve Naruto being sent on a special mission where he has no backup and has to rely solely on his own skills. Along the way, he meets different challenges that force him to innovate and combine his skills in new ways. He could also meet some strange creatures or characters that help him to further develop his 'one man band' abilities.
Perhaps Naruto discovers a hidden power within himself that allows him to perform all the functions of a team alone. He uses this power to take on a powerful enemy single - handedly and prove his worth. For example, he might be able to create clones that can perform different types of jutsu simultaneously, like one clone for taijutsu, one for ninjutsu and one for genjutsu.
One idea could be exploring the backstories of each member of the Band of Seven in more detail. For example, how they came together and what their individual motives were before joining the group.
Maybe the boy band is formed as a way to promote peace between the different ninja villages. Each member from a different village, like Sasuke from Konoha, Gaara from Suna, etc. They travel around performing and sharing their stories of how they overcame differences, which helps in building better relations among the villages.
One idea could be that Naruto and Hinata form a band together with their friends. They start off small, playing at local events in Konoha. As they gain popularity, they face challenges like rival bands trying to undermine them. Another plot could involve Hinata writing lyrics inspired by her feelings for Naruto, which adds a deeper emotional aspect to their music.
In the fanfiction, the cell could be a source of great power but also a curse. It slowly starts to take over Naruto's mind. He has to fight against its influence while also dealing with the Akatsuki who want to capture him and use the power of the cell for their own evil purposes. Naruto would have to rely on his friends and his inner strength to overcome both the threat of the Akatsuki and the cell's dark influence.
One idea could be that Naruto somehow gets transported to the One Punch Man universe. He teams up with Saitama to fight a common enemy that has the ability to absorb chakra and is also super strong physically. They start off not understanding each other's powers but gradually learn to work together.
Maybe an OC who is a sniper. The plot could revolve around their training, how they hone their skills, and the intense pressure they face during missions. They might have a personal vendetta against a particular enemy sniper, leading to a tense cat - and - mouse game throughout the story.
One interesting plot idea could be a story where only male characters from Naruto have to survive in a post - apocalyptic Konoha. They would have to rely on their ninja skills in new and extreme ways. Another could be a story about a group of male ninja forming an all - male secret society within the village with their own unique code and goals. And a third could be a tale where male Naruto characters are transported to a different dimension and have to find their way back home while facing strange new enemies.
Well, for the 'naruto the masked man fanfiction', you could have a plot where the masked man has a secret ability that only Naruto can help him control. This could lead to a unique bond between them. Or perhaps the masked man is from a different dimension and got stuck in Naruto's world, and his actions are a result of trying to get back home. Also, a story where the masked man is a time - traveler and is trying to prevent a future disaster in Naruto's world could be really interesting.
Well, a really cool plot might be that Orochimaru, always interested in new powers, somehow gets his hands on the 'All for One' concept. He could start using it to assimilate the powers of different beasts, like the tailed beasts, in a new and different way than just sealing them. Or perhaps a young genin discovers they have the 'All for One' ability. They initially use it to help their friends by taking on some of their weaknesses, but then it attracts the wrong kind of attention from the Akatsuki, who see it as a powerful tool for their own goals. Also, a time - travel plot where a character from the future with the 'All for One' ability comes back to the Naruto world to change the course of history, either for good or bad.
One idea could be exploring the relationship between Naruto and the One Tail's spirit. Maybe they can communicate in a dream - like state, and the One Tail gives Naruto some unique insights about his power and his role in the ninja world.
