One possible interesting plotline could be the exploration of the Nidaime Otokage's relationships with other Hidden Villages. Maybe he had secret alliances or rivalries that are not fully explored in the original Naruto series.
Sometimes, characters from other villages might also be involved. Maybe a ninja from Konoha who has a special encounter with the Nidaime Otokage. This could lead to an interesting exchange of ideas or a conflict that drives the story forward.
I'm not entirely sure if there is a specific, well - known fanfiction with Naruto as the Nidaime Hokage. However, given the vastness of the Naruto fanfiction community, it's very possible. Some fanfictions focus on rewriting history in the Naruto world, and this could be one of those concepts. You might have to dig around in various fanfiction websites to find one if it exists.
One idea could be exploring the Nidaime Hokage's relationships before he became Hokage. Maybe his friendships with other ninja that influenced his leadership style.
One unique part of 'naruto nidaime fanfiction' is that it can show the evolution of ninjutsu. The Nidaime was known for his powerful water - based jutsu. Fanfictions might explore how he developed those techniques and how they could have been passed down or modified over time. For example, a fanfiction could show a young ninja in the present day discovering a lost scroll related to the Nidaime's jutsu and trying to master it. This not only gives a connection to the past but also shows the growth and change in the ninja arts. Another aspect is the political intrigue. The Nidaime had to deal with a lot of political situations in the village's formation. Fanfictions can explore these complex relationships and how they shaped the village we see in Naruto's time.
One plot idea could be exploring the Nidaime Rikudo Sennin's early days. Maybe he discovers a new power that is different from what Naruto has. For example, a power related to nature spirits.
Perhaps a plot point could be centered around the Nidaime training a young ninja with potential in water - based jutsu. He could pass on his knowledge and experiences related to his water affinity. This relationship between the mentor (Nidaime) and the mentee could be filled with lessons, challenges, and growth for both characters. For example, the young ninja might struggle with a particular aspect of water control, and the Nidaime has to find a unique way to help them overcome it.
One interesting plot idea could be Naruto discovering ancient techniques that were passed down from the Nidaime. For example, he might find a hidden scroll with a unique water - style jutsu that the Nidaime was known for. Another idea is that Naruto has to face an enemy who is also related to the Nidaime's past and in order to defeat them, he has to understand his own heritage better. He could also go on a journey to the Nidaime's birthplace to learn more about his ancestor and the secrets that lie there.
A great fanfiction idea could revolve around the Nidaime's water affinity being passed down through generations. It could show how his descendants in the Hidden Leaf Village also had an inclination towards water - based techniques. The story could detail their struggles and triumphs in learning and mastering these jutsu, inspired by the Nidaime's legacy.
The story could involve Naruto facing internal resistance in the Sound Village at first. Since he's an outsider becoming Otokage, some of the traditionalist ninja in the village might oppose him. But Naruto, with his charisma and strength, gradually wins them over. He could start by solving some long - standing problems in the village, such as food shortages or issues with the local ninja academy.
One good storyline could be Naruto time - traveling and meeting the Nidaime Hokage. He could learn some long - lost jutsu from him. Another could be a story where the Nidaime Hokage is brought back to life and he has to train Naruto to face a new, powerful enemy. Maybe a story where Naruto discovers a hidden connection between his family and the Nidaime Hokage, like they were part of a secret organization in the past.
