A plot could also revolve around Naruto using his Kyuubi - sage powers to bring about peace between the different ninja clans. He could use his unique powers to show that they can all co - exist and work together. By demonstrating the strength that comes from his combination of abilities, he convinces the clans to put aside their differences and collaborate for the betterment of the ninja world.
One idea could be exploring the bond between Naruto and the Kyuubi in a new way. For example, they could have a shared dream where they are in a strange, alternate world and have to work together to find a way back. Another plot could involve Naruto using the Kyuubi's power to save a village from a new, powerful enemy that no one else can defeat. And a third could be about the Kyuubi revealing a long - lost secret about Naruto's family that changes his perspective on his own powers.
One interesting plot could be the main character exploring the unique abilities of Mokuton Sage Mode in new and unexpected ways. For example, they might discover how to combine it with other ninja techniques to create powerful new jutsus.
One idea could be the exploration of new chakra sage abilities that Naruto discovers. Maybe he can use chakra sage mode to communicate with long - dead sages and gain ancient knowledge.
A cool plot could be that the Star Sage's power was sealed away long ago because it was too dangerous. However, an evil force is now trying to unseal it. The hero of the fanfiction has to stop this while also dealing with the internal struggle of whether they should use the Star Sage's power for good, if they manage to get hold of it.
A possible plot idea for a Naruto Lightning Sage Fanfiction is that the protagonist, as a lightning sage, travels to different dimensions to gather fragments of a powerful lightning - based artifact. In each dimension, they face unique challenges and enemies. They might also encounter alternate versions of known Naruto characters. Along the way, they learn more about the true nature of the lightning sage power and how it can be used not just for combat, but also for restoration and peace - building in the Naruto universe.
One idea could be exploring Naruto's new abilities as the Sage of 6 Paths in more detail. Maybe he discovers a hidden power within the Sage mode that no one knew about before.
Perhaps a plot where the female Kyuubi has to take on a human form to protect Naruto from a new, powerful enemy. In the process, they develop feelings for each other while fighting side by side.
Another plot could involve the Kyuubi having a more sentient and family - like relationship with Naruto's family. It could communicate with them in dreams and offer advice or warnings. For example, it might warn them about upcoming threats to the village that Naruto alone might not be able to handle. This would create a unique dynamic where the family has to work with the Kyuubi for the greater good.
One idea could be that the Kyuubi's power somehow interacts with Itachi's Sharingan in a unique way. Maybe Itachi is able to use the Kyuubi's chakra to enhance his genjutsu even further. Another plot could involve Naruto, with the Kyuubi inside him, teaming up with Itachi to face a common enemy that neither could defeat alone. For example, a new powerful Otsutsuki clan member arrives, and their combined skills are needed to save the village.
One idea could be Dark Naruto forming an uneasy alliance with the Kyuubi. They might decide to take on the Hidden Leaf Village together, believing it has wronged Naruto in some way. Naruto could use the Kyuubi's power in a more sinister way than ever before.
