Some characters might be in awe. For example, Naruto himself would probably be excited to meet the reborn Rikudou Sennin, hoping to learn more about the origin of chakra and how to further peace in the ninja world. However, characters like Sasuke might be more cautious. He would be wary of the power the reborn Sennin holds and might suspect his intentions, especially if the reborn Sennin shows any signs of disrupting the current balance of power.
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.
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.
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.
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.
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 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.
His powers could be integrated in a really cool way. For example, the Rikudou Sennin's ability to control all the chakra natures might translate into some sort of unique magic control in the DxD universe. Maybe he could use his Sage Mode to enhance his perception of the supernatural elements in DxD. Since he has the power of the Ten - Tails, it could be something like a super - powerful familiar or a source of immense energy that he could draw from in battles against devils, angels, and fallen angels.
He might interact with them in a very interesting way. He could be a mentor figure to some of the younger characters, like Issei. Given his vast knowledge and power, he could teach them about different forms of energy and combat techniques. He might also be a bit of an enigma to the devils, angels, and fallen angels, as his powers are so different from what they're used to.
Rikudou Sennin's chakra could be seen as a unique power source by the DxD characters. For example, devils might try to make pacts with him to gain access to his chakra. His ability to manipulate the Six Paths powers could also give him an edge in battles against the various beings in the DxD world. He could potentially use his power to nullify some of the abilities of the angels or fallen angels.
For Naruto, if Rikudou Sennin travels back in time, he could potentially train Naruto earlier. This would make Naruto much more powerful at a younger age and might change the way he faces his enemies like Sasuke. Naruto could also learn some ancient jutsu directly from the Rikudou Sennin.
