How would Naruto's character develop in a fanfic where he has the Rinnegan?

Naruto's character would likely become more confident. Having the Rinnegan, a powerful and rare dojutsu, would give him an edge in combat and in understanding the world around him. His skills in sealing would also make him more versatile. He might become more of a thinker, as he has to combine the two abilities effectively. For example, when facing a difficult situation, he would first analyze it with the Rinnegan and then come up with a sealing solution.

Naruto would likely become more introspective. The power of the Tomoe Rinnegan is not just physical but also mental. He might start to question his place in the world more deeply, as this new power sets him apart from others. He could become more cautious in his actions as he realizes the potential destruction his new power could cause if misused.

Naruto's character would develop in multiple ways if he got the Rinnegan. Firstly, he would become more cautious. The Rinnegan is a powerful and dangerous ability, and one wrong move could have disastrous consequences. So he would think twice before acting. Secondly, he would gain a new sense of purpose. He might see himself as a guardian of a greater balance in the ninja world, not just the Hidden Leaf. His leadership skills would also be enhanced. He could use the Rinnegan to analyze battle situations more accurately and lead his comrades more effectively. Additionally, his view of the ninja world's history would expand, as the Rinnegan has connections to ancient powers and events. This would make him more of a sage - like figure, guiding the younger generation with his new - found wisdom and power.

Naruto's character would become more complex. With the Rinnegan and Jiraiya's training, he'd be more confident. He might become more of a strategist, using the Rinnegan's insights and Jiraiya's wisdom. His sense of justice could also evolve, as he'd have more power to enforce it.

Naruto would likely become more introspective. The Sharingan often comes with a lot of emotional baggage in the Naruto universe.

He could also become more cautious in battle, as he now has a power that can be both a great asset and a great danger if misused.

Naruto would likely become more confident in battle. With the Rinnegan, he has access to new and powerful techniques. This would change his fighting style and make him bolder in combat situations.

Moreover, his relationships with some characters might change. Some who were once his equals in power might now look up to him more, which could create new dynamics in his friendships and alliances.

Naruto would likely become more complex. His initial naivete might be tempered by the new power. He'd have to be more cautious as the hollow powers could be dangerous. He might also develop a darker side that he has to constantly fight against. For example, the hollow powers could bring out some of his repressed anger in a more violent way.

Naruto's character development would take a whole new turn. As a kid with the Rinnegan, he'd be seen as a prodigy. This would attract different kinds of attention, both positive and negative. He might develop a more complex view of the ninja world earlier. He would no longer be just the underdog trying to prove himself. Instead, he'd be a force to be reckoned with. His relationships with Sasuke and Sakura would also be affected. He might become more of a leader figure among them, guiding them with his newfound power, and his journey to become Hokage would have a different flavor as he would already have such a significant power advantage.

He would become more introspective. The Rinnegan has a lot of history and power, and Naruto would have to understand its origin and how to use it properly.
