A third storyline might be that Rikudou Sennin's spirit is trapped in some sort of limbo, and Naruto has to enter that realm to free him. In the process, Naruto gains a deeper understanding of the Sage's teachings and how to use his own power more effectively.
Another could be a time - travel scenario where Naruto goes back in time and meets Rikudou Sennin. They then team up to prevent a great evil from ever arising in the first place. This would allow for a lot of character development and exploration of the Naruto universe's history.
Yes, in some fanfictions, Naruto can be depicted as the Rikudou Sennin. Fanfiction writers often take creative liberties and come up with unique storylines where Naruto might inherit the powers or even be reincarnated as the Rikudou Sennin to explore different plot developments and character arcs.
One implication is that Naruto would have an extraordinary amount of power. He could potentially reshape the ninja world more easily. For instance, he might be able to end all wars and conflicts with a snap of his fingers.
Well, Naruto's chakra control and his ability to use the Nine - Tails' chakra could combine with Rikudou Sennin's more primordial and ancient chakra. Maybe they could create a super - powerful jutsu that no one has ever seen before.
In fanfiction, the idea of Naruto being the son of Rikudou Sennin can be really interesting. It could change so many aspects of the story. For example, his relationship with other characters like Sasuke might be different. His power growth could also be explained in a whole new way. But we have to remember that this is just a fan - created concept and not part of the original Naruto story. The original story has its own well - established plot and character relationships that are different from this fanfiction idea.
One way they could interact is through a power - based scenario. Naruto's chakra and ninja skills, combined with the Six Paths Sage (Rikudou Sennin) powers, could be pitted against the superpowers of the Justice League members. For example, Naruto's speed could be compared to The Flash's. And the Sage's ability to manipulate chakra on a large scale might be equivalent to some of the more powerful Justice League members' energy - based attacks.
One popular plot twist could be the Nidaime Rikudou Sennin having a hidden connection to a current character in Naruto. For example, he might be related to Naruto in a way not previously known. Another could be that his powers were sealed away for a specific reason that gets uncovered in the fanfiction. Maybe he was trying to protect the world from a greater evil by sacrificing his own power and memory.
One interesting storyline could be Naruto using the Sharingan to enhance his combat skills in a new and unexpected way. For example, he might combine his Rasengan with Sharingan - powered genjutsu to create a more powerful and deceptive attack.
One possible storyline is a cross - over where the ninjas in Naruto are exposed to the equivalent exchange principle of alchemy. They might start using it in their training, like instead of just relying on chakra, they think about what they are giving up to gain a new skill. For instance, a ninja might give up some of his speed to gain more strength. In the case of the Fullmetal Alchemist characters in the Naruto world, they could be involved in the battles between the villages. Alphonse could use his armor body to protect the villagers from attacks. And Scar from Fullmetal Alchemist could have an interesting interaction with the shinobi, as his unique form of alchemy might be seen as a very different type of jutsu.
One interesting storyline could be the combination of Naruto's ninjutsu with Final Fantasy 7's materia system. Imagine Naruto using materia - enhanced jutsus. Another could be Cloud and Naruto teaming up to fight a common enemy like Sephiroth and Madara combined. It would be epic to see their different fighting styles blend.
One possible interesting storyline could be a female Naruto ending up in the Bleach universe and learning about the different spiritual powers there. She might try to adapt her ninja skills to the new environment filled with Hollows and Soul Reapers. Another could be a Bleach character getting transported to the Naruto world and being amazed by the chakra system. For example, Ichigo might be curious about how chakra is different from his reiatsu.
