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.
Perhaps a fanfic where Indra and Asura are reborn into different clans but still retain their memories. They could try to find each other while also being influenced by the ideals of their new clans. Indra might be in a more aggressive clan and Asura in a more diplomatic one. Their reunion would then be a turning point where they either bring their clans together or cause a great conflict depending on how they handle their different upbringings.
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 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.
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, 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.
Kaguya could be a great antagonist. Even though she was defeated in the main Naruto story, she could be resurrected or have some lingering influence. Her power - hungry nature and her desire to control everything could put her at odds with Indra and Asura, who are symbols of two different paths in the ninja world. She might try to manipulate them to further her own goals or eliminate them as threats to her reign.
One idea could be exploring how Naruto's Asura reincarnation affects his relationships differently. For example, his bond with Sasuke might take on a new spiritual dimension. Maybe he starts having visions of past Asura incarnations' relationships and uses that knowledge to better understand his friends and foes.
One idea could be exploring how the reincarnation affects Naruto's relationships differently. Maybe his bond with Sasuke takes on a new dimension as they are linked in a more profound way through the Asura reincarnation. Another could be Naruto having to deal with new powers that come with the reincarnation and struggling to control them at first.
A possible plot could be that there is a cult that worships Asura and they believe Naruto is the key to bringing back Asura in his full form. They try to manipulate Naruto into doing their bidding. Naruto has to figure out their true intentions while also dealing with the fact that he might actually have the power to bring Asura back. This creates a moral dilemma for him as he doesn't know if bringing Asura back is a good or bad thing for the ninja world.
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 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.
