Well, in such fanfiction, a great idea could be the relationships. The Indra transmigrant might have a unique bond with other characters. Maybe they form an unexpected alliance with a former enemy because of their shared understanding of power and destiny. This can add a whole new layer of complexity to the story.
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.
Obviously, the Indra transmigrant is a main character. Naruto himself might also be involved as he has a connection to the whole Indra - Asura cycle. Sasuke could be another key character as he is also related to this cycle in the Naruto lore.
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 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.
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 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 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.
A fascinating plotline could be that Indra and Asura are sent on a journey through different dimensions by some ancient jutsu. In these dimensions, they see different versions of themselves and their story. They learn from these experiences and come back to their world with a new perspective, which could potentially change the course of the Naruto universe.
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.
