Well, in this type of fanfic, Fem Naruto might end up changing the history of the ninja world in the Warring Clan Era. She could use her Uzumaki heritage to her advantage. Since the Uzumaki clan was known for their strong life force and sealing techniques, she could teach these skills to other clans in exchange for peace treaties. Also, she might encounter some of the ancestors of her friends in Konoha, and this could create some really interesting character interactions and story arcs as she tries to shape the future (or rather, the past in this case) of the ninja world.
The theme of love and sacrifice also pops up. Fem Naruto may fall in love with someone from a different clan, which adds more complexity to the story. And in some cases, she has to make sacrifices for the greater good, like giving up personal relationships or even her own safety to try and bring peace to the warring clans.
The main conflict could be Naruto's struggle to fit into the very different social and cultural norms of the Warring Clan Era. As a time - traveler, she has modern ideas and values that might clash with the more traditional and clan - centric views of that time.
One popular fem Naruto warring clan era fanfic is 'The Red-Haired Kunoichi'. It has an interesting plot where the female Naruto character navigates the complex politics of the warring clans. The character development is well - done, and it gives a fresh perspective on the era.
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.
The mystery. In the Warring Clan Era, there are so many secrets about the clans, their jutsus, and their grudges. Fanfictions in this era often explore these unknowns.
One great 'Naruto Warring Era Fanfic' is 'The Shinobi's Ascent'. It has a really engaging plot that delves deep into the politics and power struggles of the warring era. The characters are well - developed, and it shows a different side of some of the well - known Naruto characters. Another good one is 'Warring Shadows'. It focuses on the impact of the wars on the common people in the Naruto world, which is a fresh perspective compared to the usual focus on the powerful shinobi.
Perhaps Shikamaru finds himself in the middle of a power struggle between two major warring clans. He has to navigate the complex politics, trying not to take sides directly at first but eventually realizing that one side is more just than the other and uses his skills to help them win. He might use his shadow - based jutsu in creative ways on the battlefield to turn the tide of battles.
One common theme is changing the past. Since Naruto travels back in time, he often tries to prevent the tragedies that led to the long - standing enmities between the clans. Another theme is the clash of values. Naruto comes from a more modern - minded era in the Naruto world, and when he enters the warring clan era, his ideas about peace, cooperation, and power are very different from those of the people there.
One common theme is revenge. If something bad happened to her family or clan, she might be on a path of revenge. There's also the theme of leadership. As a strong female character, she could be taking on leadership roles in her clan. Additionally, friendship can be a theme. She might form deep friendships with other female shinobi or even male shinobi who respect her, which is a contrast to the often - male - only friendships shown in the original context.
