A good choice could be a young Itachi Uchiha. He was a prodigy even at a young age, and his story during the clan wars era could be really interesting. He was torn between his loyalty to the Uchiha clan and his understanding of the bigger picture in the village.
It could also be a member of the village leadership who has a deep - seated prejudice against the Uchiha. This person is constantly trying to undermine the Uchiha's position and is willing to start and fuel the wars in order to get rid of them. They see the Uchiha as a threat to the stability of the village.
A great plot idea could be to explore the role of the Hyuga clan in the clan wars era. Maybe there was a power struggle within the clan regarding their stance in the wars. Or, you could write about a forbidden love story between a member of the Uchiha clan and a member of an opposing clan during this time. This would add a lot of drama and conflict to the fanfiction.
It could be a young Naruto Uzumaki, exploring his family's past during the clan wars era. He might discover secrets about the Uzumaki clan that have been long forgotten.
Hashirama Senju is a primary figure in Naruto Senju Clan Wars fanfiction. His Wood Style jutsu was not only a powerful weapon in the wars but also a symbol of the Senju Clan's strength. Tobirama, with his sharp mind, was crucial in formulating plans and counter - attacks. And on the opposing side, Madara Uchiha was a force to be reckoned with. His rivalry with Hashirama was central to the story. The interactions between these three, along with the clans they led, were what drove the plot in many fanfictions about the Senju Clan Wars.
One plot idea could be a young Naruto somehow getting transported back in time to the Uchiha Clan Wars Era. He could use his knowledge of future events and his unique skills to try and prevent some of the tragedies that occurred. For example, he might attempt to stop the initial conflict between the Uchiha and the village leadership from escalating.
I recommend 'Warring Clans: A Naruto Tale'. This fanfiction does an amazing job of showing the different fighting styles of each clan. It also has some unique takes on how the relationships between the clans were formed and broken during that time. It's full of action and drama.
There could be many interesting aspects in a fanfiction about the Naruto Badger Clan founders era. Maybe it could explore how the clan first developed their unique jutsu. For example, perhaps they discovered their signature badger - related techniques while trying to survive in their harsh natural environment.
One idea could be focusing on a young shinobi from a minor clan who discovers a long - lost clan technique during the clan wars. This technique could give their clan an edge but also draw the attention of more powerful clans. Another could be a love story between shinobi from opposing clans, with their relationship being tested by the chaos of the clan wars.
Obviously, Naruto is one of the main characters. He is usually at the center of the story, using his skills and determination to navigate the clan wars. Sasuke is also often a main character, as his past and connection to the Uchiha clan play a big role. Sakura might be there too, using her medical ninjutsu to help those injured in the wars. And then there are the clan leaders, like the Nara clan leader or the Hyuga clan leader, who have their own agendas and power dynamics within the story.
