In fanfiction, how would Godlike Naruto with Rinnegan impact the existing Naruto characters?

He would likely become more brooding. With the dark and godlike Rinnegan, Naruto might start to question his previous beliefs. He could be more isolated as he tries to figure out his new power, which is different from the chakra he's used to. His usual sunny and optimistic personality might be overshadowed by a more serious and cautious side.

The descendant would likely be in awe of Naruto at first. Since Naruto is a great hero in the Naruto universe, the descendant might look up to him and seek his guidance. With Sasuke, there could be initial mistrust as Sasuke is often cautious around new and powerful individuals. But over time, they could form an alliance to face common threats.

If Naruto got the Rinnegan, he might become more cautious. The power of the Rinnegan is so great that he would realize he needs to be more careful with it. He wouldn't be as brash as before.

The banished seal master could disrupt the power balance significantly. If they have knowledge of powerful sealing techniques, they could use it to gain an advantage over other ninja clans or villages. For example, they could seal away important resources or weapons of a village, weakening it.

They could fit in as a new type of pirate. The Rinnegan's powers would give them an edge in combat and exploration. For instance, they could use the Preta Path to absorb attacks from devil fruit users, like Logia types. This would make them a feared opponent on the high seas.

Well, perhaps the protagonist uses the powers of the Rinnegan in secret. He might train alone and develop unique abilities that others are unaware of, so that when the time is right, he can surprise everyone who has neglected him.

Well, at first it might cause some strain. His sister may feel overshadowed by Naruto's new power. But as time goes on, Naruto could use the Rinnegan to help his sister discover her own latent abilities. This would transform their relationship into one of mutual growth and support. He could use the powers of the Rinnegan to train her in unique ways, and she could in turn offer him emotional support, making their bond even deeper than before.

She would interact with Sasuke in an interesting way. Maybe she initially sees his thirst for revenge as a dangerous path similar to how kitsunes can be lured by dark desires. So she tries to steer him away from it.

Naruto himself is often included as he has a central role in the Naruto universe. Also, characters like Hinata, Sakura might be part of the harem. And Sasuke could also be involved in some way, either as a rival or an ally to the main character with the Godlike Rinnegan.

She might be initially shocked. Ino is used to Naruto's regular abilities, and the sudden appearance of the Rinnegan would be a huge change. But then she would probably be curious and eager to learn more about how it affects Naruto and what new capabilities he has.
