Well, a plot could involve Naruto's connection to Indra leading him to unlock ancient jutsu. Since Indra was a powerful figure, Naruto might have to learn to control the immense power within him. He could also be involved in a prophecy related to his father's legacy, which would set him on a path to save the ninja world in a new and unexpected way.
One interesting plot could be exploring what would happen if Ashura and Indra were reincarnated in the modern era of the Naruto world. How would they adapt to the new technology and social changes while still having their ancient feud?
Well, perhaps a plot where Asura and Indra are given a chance to rewrite their history. They start to understand each other's viewpoints better and try to create a new future for the ninja world. They could also meet their descendants, like Naruto and Sasuke, in a different dimension and exchange knowledge and power.
One interesting idea could be exploring how the Indra transmigrant copes with the memories and powers. For example, they might struggle to control the immense power which could lead to some internal conflicts.
One idea could be exploring their relationship in a modern AU. Imagine Indra and Asura as two brothers in a modern city, dealing with normal life problems while still having their spiritual connection. They could struggle with family expectations, like Indra being the over - achieving older brother and Asura the more laid - back one, but they have to come together to face a common threat that has a connection to their past lives.
Well, a plot could be that Sakura is a healer in a war - torn land and Indra is a powerful warrior. Indra gets seriously injured and Sakura has to use her skills to heal him. During his recovery, they start to have deep conversations about life, power, and the purpose of war. This could lead to a change in Indra's perspective on things and a budding relationship between them. It could also create conflict as some in Indra's clan might not approve of his new - found friendship with Sakura.
One plot idea could be that Ashura and Indra are reincarnated in a modern world where Naruto and Sasuke have to figure out how to deal with their past memories and powers. Another could be a story where they team up to fight a new, powerful enemy that is threatening the ninja world and they have to overcome their differences, just like Naruto and Sasuke did in the original story.
One interesting idea could be the exploration of how the reincarnation affects Naruto's relationships. For example, how it changes his bond with Sasuke, as Sasuke is often linked to Indra. Maybe it could lead to a deeper understanding between them, beyond their normal rivalry.
One idea could be Indra Otsutsuki crossing over into a modern-day world. He could struggle to adapt to the new technology and social norms while still having his powerful ninja abilities. Maybe he meets a group of people who initially fear him but then come to understand his situation and help him navigate this strange new world.
A fanfic could focus on a time - travel plot. For example, Asura or Indra gets sent to a different era and has to adapt while also finding a way back. Along the way, they encounter versions of themselves or each other from that time and have to deal with the consequences of interfering with the timeline.
One idea could be a story where Naruto, as a mediator, tries to bridge the gap between Sasuke, representing Indra, and someone who has the spirit of Ashura. Maybe they have to work together to stop a new, powerful threat that only their combined powers can defeat. For example, a dark force that is trying to break the cycle of reincarnation between Indra and Ashura.
