One possibility is that Naruto has a spiritual journey with Rikudou Sennin. They could travel through different time periods related to the history of the ninja world. Naruto would see first - hand how the world came to be the way it is. And through this journey, Naruto's understanding of his own purpose and the ninja way could be deepened. Rikudou Sennin might also reveal some hidden prophecies or destinies that Naruto has to fulfill.
It could be an ancient evil that Rikudou Sennin once sealed away. With Naruto and Rikudou Sennin meeting, this evil might sense an opportunity to break free and becomes the antagonist.
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.
One interesting plot could be that Rikudou Sennin is reborn into a time when the ninja world is on the verge of a new, unknown threat. He has to quickly regain his powers and knowledge to guide the new generation of ninjas, like Naruto and his friends, to face this threat. Maybe he has lost some of his memories in the rebirth process, adding an element of mystery and self - discovery to the story.
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.
It could be a powerful dark ninja who has discovered a way to tap into an ancient and evil power source. This ninja wants to use this power to rule the ninja world and sees Rikudou Sennin's rebirth as a threat to his plans.
One possible plot could be that Rikudou Sennin somehow gets transported to the world of Highschool DxD. Maybe his powers disrupt the balance there. For example, his chakra could be mistaken for some kind of new and strange power in the DxD world. The characters in DxD might initially be wary of him but then start to see the potential of his abilities and try to recruit him for their own purposes.
If Naruto were the son of Rikudou Sennin in fanfiction, it would have far - reaching consequences. His place in the ninja world would be completely redefined. He might be seen as a sort of messiah figure, especially among those who revere the Sage of Six Paths. His training and development would likely take on a whole new dimension. Instead of struggling to gain power and recognition as in the original story, he might start with a much higher status. This could also lead to new rivalries or alliances. For example, some clans might try to curry favor with him, while others might see him as a threat to the existing power balance. And his relationship with the tailed beasts could be even more profound, as he would have a closer connection to the origin of chakra through his supposed father, Rikudou Sennin.
One interesting story could be about Rikudou Sennin's early days and how he discovered his powers. Maybe it shows his first encounters with the chakra beasts.
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.
