It could change the power dynamics in the village. In the normal Naruto storyline, as Naruto grew in rank, he became a symbol of hope and strength for the village. If he remains a genin, there could be a power vacuum at the higher ranks that other characters might try to fill. This could lead to new rivalries and alliances within the village. And Naruto himself might have to find new ways to prove his worth, not just through rank but through his actions and the unique skills he develops at the genin level.
Since Naruto is still a genin, he may not be allowed to participate in certain high - level missions. This could limit his exposure to different parts of the ninja world and delay his overall growth in terms of knowledge and experience. However, it could also lead to him finding creative ways to get involved in important matters, like sneaking into missions or solving problems from the sidelines. Also, his relationships with other characters might be affected. For example, some characters who only respect higher - ranked ninjas might not take him seriously.
One consequence could be that he might face more discrimination from the village elders. In the original story, as Naruto advanced in rank, he gained more respect. But as a genin here, he could still be seen as a troublemaker. Another consequence is that his training might be different. He might focus more on basic genin - level skills, which could make him even stronger in the long run as he masters them to a higher degree.
Maybe the author wants to explore more of Naruto's growth at the genin level. There could be many untold stories and character developments that can happen during this stage. It gives the author more space to show Naruto's relationships with his friends, like Sasuke and Sakura, in a different light while still being a genin.
He might be disqualified. If Naruto gets hurt badly during the Genin Exam in fanfiction, the examiners could decide that he is no longer fit to continue and thus disqualify him. This would be a huge setback for him as becoming a Genin is his big dream.
His reputation in the ninja world could be damaged. If Padme spreads false information or reveals his secrets, other ninja might view Naruto differently. They could see him as a liability or a threat. This could lead to him being isolated in the ninja community, and he might have to fight harder to prove himself again.
One possible consequence could be that Naruto is ostracized by some in the ninja world. Since controlling blood is a rather strange and perhaps 'creepy' ability to some, they might view him with suspicion or fear. This could lead to him having to prove himself more often in battles and interactions.
There could be a character who has a disability in the ninja world, like being partially blind but having an amazing sense of hearing or smell. Naruto would see their potential and include them in the team. Another member could be a former criminal's child who is trying to make a name for themselves in a positive way. And there could be a super - intelligent ninja who is great at strategy but lacks in practical combat experience, and Naruto would help them gain that experience.
One aspect to consider in a Naruto and Hinata fanfiction could be their growth as genin. Naruto was always full of energy and determination. Hinata, on the other hand, was shy but had a strong will. In a well - written fanfic, their relationship could develop as they train together and face challenges. For example, they might start to understand each other's dreams better. Naruto could inspire Hinata to be more confident, and Hinata could teach Naruto some of her family's unique techniques.
The evolution of the Rinnegan in Naruto might also have an impact on his own identity. He has always been known as the 'knuckle - head ninja' with his own unique set of abilities. Now, with the Rinnegan, he has to come to terms with this new and extremely powerful aspect of himself. He might struggle with the moral implications of using such power. For instance, he might be tempted to use the Rinnegan's more dangerous abilities in a fight, which could go against his usual principles of not killing his opponents.
One possible consequence is that the power balance in the ninja world is completely disrupted. With the Kyuubi's massive chakra and power running free, smaller villages might be constantly in fear of being attacked. Konoha, in particular, would have to find new ways to defend itself without relying on the fact that the Kyuubi is sealed within one of its shinobi.
In fanfiction, it could also attract unwanted attention. If Naruto summons Rashomon in a public place or during a battle, it might draw the eyes of even more powerful enemies or villains who would then target him specifically because they see him as a threat with this newfound ability. For example, some secret organizations might see him as a potential tool or a danger to their plans and start to plot against him.
There could also be environmental consequences. If Naruto isn't fully in control of his flood - controlling ability, he might accidentally cause damage to the local ecosystem. For example, he could disrupt the natural flow of rivers and flood areas that are important habitats for animals and plants.
