Well, there are several implications. Firstly, from a power - perspective, Naruto being the Rikudo Sennin means he has access to all the powers and knowledge that the Rikudo Sennin had. This could include the ability to control all the tailed beasts more effectively, or perhaps even new jutsu that were previously unknown. In terms of character development, it would be a huge shift. Naruto has always been on a journey to become stronger, but suddenly being the Rikudo Sennin would mean he has reached the pinnacle of power in a very different way. His relationships would also be drastically altered. His friends, who have known him as the underdog Naruto, might struggle to come to terms with this new, all - powerful version of him. His enemies, on the other hand, would be faced with an almost unbeatable foe. And from a story - telling point of view, it opens up a whole new set of story arcs. The fanfiction could explore how Naruto uses his new powers to deal with old and new threats, how he manages the power balance in the ninja world, and how his new status affects his own self - identity.
One implication is the change in power level. Naruto as the Rikudo Sennin would be extremely powerful, which could lead to different battle outcomes. For example, he could easily defeat enemies that were previously tough for him.
Yes, in some fanfictions Naruto is depicted as the Rikudo Sennin. Fanfiction writers often like to create alternate storylines where characters take on different roles or powers, and this is one such example.
The 'naruto heir of the rikudo sennin fanfiction' might be centered around Naruto's growth as the heir. It could include things like Naruto learning the secrets of the Rikudo Sennin, perhaps unlocking some hidden jutsu or knowledge. There could be a focus on the political implications as well, like how different ninja villages react to Naruto being the heir. And it may also involve Naruto's struggle to balance his newfound responsibilities with his own goals and values.
The main character is Naruto as he is the heir of the Rikudo Sennin. However, other characters are likely to be involved too. Jiraiya could be a key figure in this fanfiction, considering his connection to Naruto and his knowledge of the past. Additionally, the antagonists in the Naruto world might also be main characters in a sense, as they would oppose Naruto's rise as the heir, either out of jealousy or a desire for power themselves.
One interesting plot could be that Rikudo Sennin from the Naruto universe gets accidentally transported to another dimension where he meets characters from a different story. He then has to use his powerful jutsu and wisdom to find a way back home while also getting involved in the affairs of that new world, like helping the local heroes fight against a powerful villain.
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.
It could show Naruto trying to master the same level of power as Rikudo Sennin. He might struggle with the moral implications of such great power, as Rikudo Sennin had to make difficult choices in his time.
The main antagonist could be an ancient evil that was sealed away by Rikudo Sennin long ago. But due to some disruption in the fabric of space - time in the crossover, it gets released. This evil being has powers that rival Rikudo Sennin's and it wants to take over both the Naruto world and the world it was sealed in.
Another great plot twist could be related to the memories of the reincarnation. Instead of gradually remembering past lives like in typical reincarnation stories, the reincarnation of Rikudo Sennin has all the memories at once but can't control them. This could lead to some really chaotic and interesting situations where the character is constantly fighting between their current self and the memories of a powerful sage.
A possible plot could involve Rikudo Sennin's spirit being awakened in modern - day Naruto's world. He could possess someone and start causing chaos as his old - fashioned beliefs clash with the current ninja society. Naruto would then have to find a way to stop him without harming the innocent person he's possessing.
One plot idea could be exploring the Nidaime Rikudo Sennin's early days. Maybe he discovers a new power that is different from what Naruto has. For example, a power related to nature spirits.
