The protagonist could be focused on understanding the full potential of the Rinnegan. Since he is neglected, he has more time to himself. He might explore the different paths of the Rinnegan, like the Deva Path, Asura Path etc., and gain strength from it. He may also be biding his time, waiting for an opportunity to show his true worth and make those who neglected him regret their actions.
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.
The Rinnegan is often neglected in Naruto fanfiction perhaps because it represents a very high level of power that can be intimidating for writers to handle. If a writer wants to create a more relatable or character - driven story, they might shy away from using the Rinnegan. Additionally, the fanfiction community may have certain trends that favor other elements of the Naruto universe over the Rinnegan, so it doesn't get as much attention.
In fanfiction, Naruto having the Rinnegan and being neglected by parents can lead to some really interesting character development. It could make him more self - reliant and distrustful at first. He might have to learn to harness the power of the Rinnegan on his own, without any parental guidance. This could result in him making some mistakes along the way but also growing stronger in unique ways.
One possible plot could be that the main character, who has the Rinnegan but has been neglected in the original Naruto story, decides to form their own ninja clan. They use their Rinnegan powers in unique ways to train their clan members and rise to power. This would be a new take on the Naruto universe and could explore the untapped potential of the Rinnegan.
Naruto could develop a more cautious side. Since the Rinnegan is such a powerful and previously neglected thing, he would need to be careful. For example, he might start to study and analyze situations more before jumping into action like he used to.
Well, perhaps in the fanfiction, the neglected Rinnegan was actually a key to an ancient prophecy. Naruto, being the protagonist, starts to notice strange things related to the Rinnegan. He could then embark on a journey to understand its true significance. Along the way, he might meet old enemies who now have a newfound interest in the Rinnegan because of its newly discovered potential.
It could be an unknown Uchiha who was overlooked in the main story. Maybe they were born with the Rinnegan but due to some political unrest in their village, they were forced to hide their power and were thus neglected. In the fanfiction, they could come out of hiding and shock everyone with their Rinnegan - based abilities.
Maybe the Rinnegan is not just a normal Rinnegan. It could be a mutated form that has powers beyond what anyone expected. As the story progresses, the protagonist discovers these new powers bit by bit, which completely changes the power dynamics in the Naruto world and makes everyone who neglected him scramble to get on his side.
It might be explored through lack of training or guidance. Since he's godlike, the village might think he doesn't need any help. So, they neglect his development in terms of combat strategies or new jutsu, leaving him to figure things out on his own.
He might start to rely on his friends more. For example, Sasuke and Sakura could become his main source of emotional support. He would focus on training with them and sharing his feelings, which in turn helps him to grow stronger and more independent.
Well, for starters, his power progression would be completely different. Without parental support, he'd have to figure out the Rinnegan's abilities all by himself. Maybe he'd accidentally unlock some dangerous powers early on because he didn't have anyone to guide him. His emotional state would also be a mess. He'd probably be angry at his parents for neglecting him and use that anger as fuel to train harder.
