In Naruto Rinnegan Hokage Fanfiction, who could be Naruto's main rival with his new powers?

Perhaps he could obtain the Rinnegan through some sort of ancient ritual or a gift from a powerful entity. And to become Hokage, he would need to prove himself worthy through his deeds and leadership skills, like protecting the village from a major threat.

Naruto's character development would likely become more complex. With the Rinnegan and Sharingan, he would have access to a whole new level of power and knowledge. He might become more introspective as he tries to understand and control these powers. His relationships could also change. For example, his friends might view him differently, with a mix of awe and perhaps a bit of wariness due to the potentially overwhelming nature of these powers.

One great fanfiction idea could be about a character who has both the Rinnegan and Sharingan and uses them to travel through different dimensions in the Naruto universe. They could encounter ancient and powerful beings, and learn new jutsu that combine the unique abilities of both eyes.

One interesting fanfiction idea could be a story where a new character is born with a combination of all three powers. This character would face many challenges as the ninja world would either fear or try to use this unique being for their own gain.

Perhaps a plot where Naruto's Rinnegan is a result of a curse placed on him by an ancient evil. As Hokage, he has to not only fight against external threats but also the inner struggle of controlling the power of the Rinnegan without succumbing to the curse. He could learn about the origin of the Rinnegan from old scrolls and seek the help of sage-like characters to overcome the curse.

In such a fanfiction, Naruto would be extremely powerful with the Rinnegan. He could use powerful jutsu like the Six Paths techniques. As Hokage, he would bring a new era of peace and strength to the village. His Rinnegan abilities might help in better defense against threats and also in diplomatic relations as other villages would fear his power.

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 a rogue ninja who was once a part of Konoha but was banished for unethical experiments. Now, with a thirst for revenge against Naruto and the village, he returns as a powerful and unpredictable foe.

Well, it depends on the specific fanfiction. Some fanfictions might explore alternate storylines where Naruto doesn't become the Hokage at all. Maybe he decides to pursue a different path in life, like focusing on being a teacher or an explorer. However, in a large number of fanfictions, he does achieve his goal of becoming the Hokage because it's such an iconic and desired outcome for fans who want to see his journey to the top in different ways.

It could be the First Hokage, Hashirama. Naruto would be amazed by his powerful Wood - Style jutsu and his ability to create the village. He could learn about the original ideals behind the Hidden Leaf from Hashirama.
