Who would be the most suitable antagonist in a 'Naruto Asura and Indra fanfiction'?

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.

Often, other characters from the Naruto universe also make appearances. For example, the various ninja clans like the Uchiha and the Senju. Their loyalties and relationships with Indra and Asura can add depth to the story. Maybe there are also some original characters created by the fanfiction writer to interact with Indra and Asura and drive the plot forward in unique ways.

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 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.

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.

Another possible antagonist could be a rogue ninja from Hailbel's past. This ninja could have a vendetta against her family or something she did in the past. When he discovers that Hailbel is with Naruto, he decides to take them both on. He might have some unique and dangerous techniques that Naruto and Hailbel have to figure out how to counter.

The concept changes the relationships too. Naruto's relationship with Sasuke could be seen in a whole new light. Since Sasuke is related to Indra, they might have a more fated connection. They could be forced to work together more often to fulfill some greater destiny related to their reincarnation status. Also, the way other characters view Naruto could change. They might see him as a more significant figure in the grand scheme of things, not just as a powerful ninja but as a key part of a long - standing cycle.

It could be Naruto. He has a strong will and the ability to make others follow him. His positive attitude might overshadow Indra's more brooding nature.

One common theme is the struggle against society. Since their relationship might be seen as unconventional, they often have to face opposition from the world around them.

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.
