Naruto Senjutsu Crossover Fanfiction: What are some interesting plot ideas?

Perhaps a plot where Naruto has to teach the Sage of Six Paths Senjutsu to a new generation of ninjas. This could involve dealing with their different learning abilities and personalities, and also facing threats from those who want to misuse this powerful technique. It could also show how Naruto has grown as a teacher and a leader.

One interesting plot idea could be Naruto exploring the full potential of the Six Paths Senjutsu in a new, uncharted dimension. He could discover hidden abilities that were previously unknown, like the power to manipulate time on a small scale while in that state. Another idea is that Naruto uses the Six Paths Senjutsu to communicate with past Hokages in a more profound way, learning ancient secrets that help him defeat a new, powerful enemy threatening the ninja world.

One plot idea could be that Naruto characters end up in Ikebukuro. For example, Naruto himself could be searching for a new type of ninja tool that he heard can only be found in Ikebukuro. Meanwhile, the gangs in Durarara start to notice this strange, orange - clad boy with strange powers. Another idea is a character swap where some of the Durarara characters gain ninja abilities and get involved in Naruto - style battles in their own world. Maybe Celty could use her shadow powers in a more ninja - like way, like stealth and quick attacks.

One idea could be that Naruto characters are transported into the Splatoon world. They might initially be confused by the ink-based battles and the unique species. For example, Naruto could mistake an Inkling for a strange ninja from another land and challenge them to a friendly spar, only to find out about the ink shooting mechanism. Another plot could involve the Akatsuki from Naruto trying to steal the valuable ink resources in the Splatoon world for their own purposes. They would face off against the Splatoon heroes who are determined to protect their world's resources.

A cool plot could be that there's a tournament across different anime worlds, and Inuyasha and Naruto are chosen to represent their respective worlds. Along the way, they discover similarities in their pasts, like both having some form of demon - related heritage (Naruto with the Nine - Tails and Inuyasha being a half - demon). They also exchange combat techniques. Naruto teaches Inuyasha how to better use chakra control in his attacks, and Inuyasha shows Naruto some unique sword - fighting skills.

One interesting plot idea could be that Kaguya is reborn in the modern Naruto world. She has no memories of her past at first. Naruto discovers her and senses a strange power within her. As she starts to regain her memories, she struggles between her old self and the new world she's in. Naruto has to decide whether to trust her or not.

Perhaps the nine - tailed fox in Naruto and the Avatar state could have some sort of connection. In the fanfiction, the two powers could interact in unexpected ways. For example, when Naruto enters his nine - tailed fox mode, Aang's Avatar state could be affected, or vice versa. They might have to learn to control these interactions to save both their worlds from a dark force that wants to use this power connection for evil.

One idea could be that Naruto gets a gamer power that allows him to level up his ninja skills like in a game. For example, he can see his progress in learning new jutsus as leveling up. Another could be a crossover with a popular game world where Naruto has to fight game bosses using his ninja abilities.

A plot could involve a villain who wants to steal the Vocaloid's voices to use as a weapon in the Naruto world. The voices could be used to control people or summon powerful creatures. Naruto and his friends would have to team up with the Vocaloid characters to stop this villain. They would need to figure out how to protect the voices and use the Vocaloid's musical powers against the villain.

One plot idea could be Naruto being banished to the world of One Piece. He could join the Straw Hat Pirates and use his ninja skills in new and exciting ways. For example, his shadow clone jutsu could be used for various tasks on the ship. Another idea is that he gets banished to the Bleach universe. He might learn about Soul Reapers and Hollows, and his chakra could be seen as a unique form of spiritual energy there. Maybe he could even train with the Soul Society to become stronger.
