Another plot could involve Naruto struggling to control these new powers at first. Since they are so powerful and different from his normal chakra abilities. He might accidentally cause some chaos in the village, but then with the help of his friends, he learns to master them and use them for good. For example, he could use the Rinnegan's ability to revive the dead in a limited way to bring back some of the ninjas who sacrificed themselves in previous battles, but this also comes with a cost or consequence that he has to face.
One possible plotline could be Naruto using the EMS and Rinnegan powers to finally bring true peace to the ninja world. He might use the enhanced visual abilities of the EMS and the god - like powers of the Rinnegan to defeat a new, extremely powerful enemy that no one else could handle.
In fanfiction, one way to combine EMS (Eternal Mangekyou Sharingan) and Rinnegan powers could be through a powerful jutsu. For example, a character might create a new form of ninjutsu that draws on the unique abilities of both. The EMS could provide enhanced visual perception and the ability to cast powerful genjutsu, while the Rinnegan could offer control over different elements and the six paths techniques. They could be combined in a way that allows for teleportation between different dimensions, using the space - time manipulation aspects of both powers.
It could be interesting to see Naruto with both EMS and Rinnegan in fanfiction. Naruto is known for his Uzumaki vitality and his ability to master new powers quickly. Having EMS and Rinnegan would give him an entirely different set of skills. He could combine the Rasengan with Rinnegan - based techniques and use the EMS - enhanced perception to dodge attacks even better. His positive attitude and never - give - up spirit would make for an exciting exploration of these powers.
One idea could be that Naruto somehow gains the EMS (Eternal Mangekyou Sharingan) and Rinnegan powers simultaneously. Maybe through some ancient jutsu experiment gone wrong/right. He then has to learn to control these new powers while facing an old enemy who has also gained a new and dangerous power. This would lead to epic battles and Naruto exploring new ways to use these combined powers, like using EMS - enhanced speed with Rinnegan - based space - time ninjutsu.
In some 'naruto of the rinnegan fanfiction', there might be a plotline where Naruto uses the Rinnegan to bring back characters from the dead. This could lead to all sorts of emotional reunions and new challenges as the balance of the world is disrupted.
A third plot idea is that Naruto is given the Rinnegan as a last resort to save the ninja world. An old sage or some kind of divine being bestows it upon him. But with the Rinnegan comes a prophecy that he will either save or destroy the world. Naruto then has to battle his inner demons as well as external foes, all while trying to understand the true nature of the Rinnegan and its place in his destiny.
Another plot could be that the Rinnegan was secretly implanted in Naruto by an enemy as part of a long - term plan to turn him evil. Naruto then has to struggle not only with the new power but also with the dark influence it tries to exert on him. His friends initially suspect him, but he has to prove that he's still the same Naruto while also trying to figure out how to get rid of the Rinnegan's negative effects.
One plot idea could be that Naruto discovers the Tomoe Rinnegan during a new and powerful enemy encounter. With this new eye power, he gains abilities like enhanced space - time manipulation and can see the chakra flow in a more detailed way. This changes his fighting style and makes his enemies struggle to adapt.
A possible plot could be that Naruto, with his Rinnegan and Mokuton, is seen as a threat by some of the more traditional ninja clans. They form an alliance against him, but Naruto uses his powers in creative ways to show them that he only wants to use them for good. For example, he uses the Mokuton to create a beautiful forest in the middle of a desolate area, and uses the Rinnegan to heal some of the injured ninjas from the clans that oppose him, winning them over in the end.
One possible plotline could be Naruto forming a unique bond with Chomei. Maybe Chomei helps Naruto in a difficult battle by using its special abilities, like its ability to manipulate the nano - sized insects. This could give Naruto an edge against a powerful enemy.
Another plotline could involve a young and unknown ninja from a minor clan who suddenly awakens the Rinnegan. This causes a stir as the major clans see this as a threat to their dominance. The story could then follow this ninja's journey as he tries to master the power while fending off attacks from the other clans.
