One popular theme could be Naruto's inner struggle with his darker side. Another might be alternate storylines where Naruto's character takes a more morally ambiguous path. For example, a theme could explore how Naruto deals with power if it starts to corrupt him.
Obviously Naruto is the main focus most of the time. But other characters like Sasuke can also be important. Sasuke's own dark past and his relationship with Naruto can be further explored in a 'dark' context. For example, they might become rivals in a more extreme and less friendly way.
One great 'oto Naruto fanfic' is 'The Legacy of the Uzumaki'. It focuses on Naruto's journey to discover more about his Uzumaki heritage. The story has well - developed characters and exciting plot twists.
Since I haven't actually read this particular fanfic, it's hard to say exactly what it's about. However, given that it's a Naruto fanfic, it could be about any number of things. It might be a story that delves into the backstory of a minor character, giving them more depth and significance. It could also be a story that combines different elements from the Naruto series in an unexpected way, such as mixing different jutsu or having characters from different clans interact in new and interesting ways.
In the context of 'naruto sound of oto fanfic', it could be a story that delves into the history of the Sound Village. It might tell tales of how the village was founded, the significance of sound in their culture and fighting styles. For example, it could explore how the Sound ninjas use sound to enhance their stealth or to detect enemies. It might also show how the village has changed over time and its relationships with other villages in the Naruto world.
An engaging plot is crucial. It could be a new adventure for Naruto and his friends, or a different take on an existing storyline. For instance, a fanfic that changes the outcome of a major battle in the Naruto series can be really interesting. It should also have a good pacing, not too slow or too fast, to keep the readers hooked.
One of the potential allies could be Jiraiya. Even though he has his own ties to Konoha, he might see Naruto's leadership in Oto as a way to bring about a new balance in the ninja world. Also, some of the more open - minded members of Oto itself could become Naruto's allies. They might be impressed by Naruto's leadership skills and his vision for the organization, which could be different from what Orochimaru had in mind.
There could be an old and wise master in the Sound Village in this fanfic. This master has seen the village through many changes and has a deep understanding of the true power of sound.
