In some fanfictions, the reincarnation can lead to the main character forming unexpected alliances. They might see the potential in a character who was overlooked in the original story and form a strong bond with them. This can change the whole dynamic of the story and how different characters interact with each other.
Well, it can make their relationships quite complex. If the main character has memories of their past life, they might act differently towards their new friends and family. For instance, they could be more guarded or overly protective because they know how cruel the world can be from their past experiences.
As for his relationship with the villagers, some might fear him more because of his connection to Indra. They could see him as a potential threat, like they did in the beginning when they were afraid of the Nine - Tails within him. However, others might see it as a sign of Naruto's importance and start to respect him even more, believing that he is destined for great things because of this reincarnation.
To create a compelling OC (Original Character) for a My Hero Academia reincarnation fanfiction, first consider their quirk. It should be unique yet fit within the world's power system. For example, a quirk like 'Elemental Mimicry' where the character can mimic the properties of different elements. Then, think about their backstory. Maybe they were an ordinary person in their past life who had a strong sense of justice. This could fuel their actions in the new world of heroes and villains. Also, give them flaws. A character who is too perfect is uninteresting. Maybe they're overly impulsive or have a fear of heights which could add depth to their story.
Well, Naruto's relationship with Hinata could be affected in several ways. If Naruto is reincarnated as Kaguya, Hinata might feel a bit distanced from him at first. She would be confused about this new side of Naruto. Also, the other villagers might start to fear Naruto, which could put a strain on his relationship with the whole village. But if Naruto can prove that he's still the same person deep down, he might be able to repair those relationships. His relationship with Kakashi would also change. Kakashi, being a knowledgeable person, would try to guide Naruto through this new development.
For Naruto's friends like Shikamaru and Choji, they would be quite surprised. Naruto might start to act more like Tobirama in some ways, which could be a bit off - putting at first. He could be more strict or more focused on the long - term goals of the village. This might cause some friction in their friendships until they understand what's going on. With the elders of the village, Naruto could gain more respect as Tobirama was a highly respected figure. But it could also make some of them wary, as they might fear Naruto using Tobirama's knowledge in ways they don't like.
Another common trope is the main character having memories of their past life. This often leads to them having a different perspective on the events in the MHA universe. They might use their knowledge of the original story to their advantage, like knowing the weaknesses of certain villains or the secrets of powerful heroes.
You can start by giving them a unique quirk. For example, a quirk that allows them to manipulate time on a small scale, like slowing down time for a few seconds during combat. This would set them apart from the existing characters in the series.
A character's wishes could determine the type of Pokemon they become. If they wish for strength, they might be reincarnated as a powerful and rare Pokemon like Tyranitar. If they wish for speed, perhaps a Pokemon like Electrode would be their new form.
One interesting concept could be the character having prior knowledge from their past life and using it to their advantage in the My Hero Academia world. For example, they might know combat techniques that are not common in that universe and use them to stand out.
One common plot idea is the OC trying to become the top hero. They use their knowledge from their past life to gain an edge. For example, they know the training methods of the best heroes and apply them to their own training. Another idea is the OC changing the fate of certain characters. Maybe in the original story, a side character dies, but the OC intervenes to save them. Or they could be involved in uncovering a conspiracy within the hero society that was hidden in the original story.
A more complex plot could be that the OC reincarnates into a world where the events of 'boku no hero academia' have taken a different turn. Maybe All Might was defeated much earlier and the villains are in almost complete control. The OC has to find a way to gather the remaining heroes, train them in new ways, and inspire hope again. This would involve a lot of character development as the OC has to prove themselves to the jaded heroes and also face the very powerful villains.
