The impact on the ninja world. Their roles as Indra and Ashura are not just about themselves. It should have an impact on the whole ninja world. You could write about how the other ninja clans react to their connection. Some might see them as saviors, while others might fear their combined power and try to undermine them.
The power dynamics between them. Since Indra was known for his power and Sasuke has always been a strong character, and Naruto as Ashura is also very powerful. Their battles and how they balance each other's powers would be important. For example, when they fight side by side, how they combine their different chakra natures and jutsu.
A fanfic could explore what if Naruto and Sasuke were fully aware of their Indra and Ashura identities from the start. Maybe they are born with memories of their past lives. This would completely change their relationship dynamic. They could be more united from the beginning, working together to reform the ninja world according to the will of their predecessors. They might introduce new jutsu and ninja teachings based on the ancient knowledge of Indra and Ashura, which would face opposition from the traditional ninja clans who are resistant to change.
A great Naruto Sasuke Ashura Indra fanfiction might focus on the powers they possess. Ashura and Indra had unique abilities, and imagining how Naruto and Sasuke could inherit or be influenced by these in new ways can be exciting. For instance, Sasuke could gain a deeper understanding of Indra's power and use it to create a new jutsu that combines both his own skills and the ancient power, which would make him even more formidable in battles against new threats.
Some fanfictions might explore how Ashura and Indra's past actions could have different impacts on Naruto and Sasuke. Maybe in a fan - made story, Indra's actions in the past were misinterpreted, and Sasuke has to figure out the truth. This could change his entire perception of his own power and destiny.
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 common theme is the struggle between power and peace. Indra was often power - hungry while Ashura was more about peace. Another theme is the idea of destiny and reincarnation. Since they are reincarnations in the Naruto lore. And family ties also play a big role as they are brothers.
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.
The relationship between Sasuke and Naruto could be developed by having them actually communicate as the reincarnations of Indra and Ashura. They could have deep discussions about the burden of their pasts and how to break free from the cycle of hatred. For example, Naruto could share his experiences of always trying to find the good in people, which might make Sasuke re - evaluate his own views.
Indra and Ashura were the sons of the Sage of Six Paths. Indra was extremely talented in ninjutsu from a young age. He was strong - willed but also grew jealous of Ashura. Ashura, on the other hand, didn't have as much natural talent as Indra in ninjutsu but was very kind - hearted and had strong bonds with people. Their different paths led to a feud. Indra believed in power through strength alone, while Ashura thought power came from the people around you and their support. Eventually, their conflict passed down through generations in the ninja world, and it was a big part of the backstory in Naruto that influenced many events and characters like Sasuke and Naruto who were seen as the reincarnations of Indra and Ashura respectively.
The plot could involve a tournament. Sakura, Ashura, and Indra could all be participants. They would have to use their unique skills to compete. Sakura's strength and intelligence, Ashura's connection to nature and his people - loving nature, and Indra's powerful jutsu would all be put to the test.
One popular 'naruto indra ashura fanfic' is 'The Legacy of Indra and Ashura'. It delves deep into their relationship and how it shaped the ninja world. Another great one could be 'Indra and Ashura: Reborn'. It has an interesting take on their reincarnation concept in the Naruto universe. And 'Indra's Path to Redemption' is also quite good, which shows Indra's journey towards a different path than his previous one.
