Perhaps there is a scenario where Naruto is framed for a crime he didn't commit. His friends, believing in his innocence wholeheartedly, protect him from the angry villagers and work hard to clear his name. They might use their unique skills, like Sasuke's sharingan to find clues, and Sakura's medical knowledge to keep Naruto in good health during this tough time.
Obviously, Naruto is one of the main characters. His friends like Sasuke, Sakura, Kakashi, and others are also likely to be main characters as they are the ones protecting Naruto.
In some fanfictions, the Kyuubi's protection might lead to Naruto having a special bond with nature. Since the Kyuubi is a powerful force, it could influence Naruto's chakra in a way that makes him more attuned to the natural elements around him. This could give him an edge in battles, like being able to manipulate the environment in ways others can't.
One idea could be to explore the friendships in different time periods. For example, how their friendships might have been different during their academy days compared to when they are on missions as adults. Another could be a 'what if' scenario, like what if Naruto made friends with an outsider to the village early on.
One plot idea could be that Naruto is on a dangerous mission and the strong girls, like Sakura and Hinata, form a protective shield around him. They use their unique skills, Sakura with her medical ninjutsu and combat abilities, and Hinata with her Byakugan and gentle fist. Another idea is that the strong girls protect Naruto from the villagers' scorn and threats, gradually changing the villagers' views on Naruto through their influence.
One interesting 'Friends' fanfiction story could be about what would happen if Chandler and Joey's acting careers took off in a different direction. Maybe they got a big break in a serious drama instead of their usual comedic roles. Another could be a story where Phoebe discovers she has a long - lost relative who is also a bit of a free spirit like her. There are also fanfictions that explore Rachel's life if she had stayed in Paris and how that would have affected her relationships with the rest of the gang.
One interesting story in friends fanfiction could be about Chandler and Joey's adventures after they move out of their apartment. Maybe they travel the world together and get into all sorts of comical situations. Another could be a story that focuses on Phoebe's early life before she met the gang, like how she survived on the streets. And there might be a fanfiction where Ross and Rachel finally have a completely drama - free relationship and just enjoy their time together as a couple.
One interesting plotline could be Naruto and Sasuke going on a journey together outside of the Hidden Leaf Village to explore a new land filled with strange creatures and unique ninja techniques. They could face challenges that force them to rely on their friendship more than ever.
Another plot could be Kyuubi teaching Naruto some ancient and forgotten ninja techniques. As a powerful and ancient being, Kyuubi might know some techniques that have been lost over time. Naruto could then use these new techniques to surprise his opponents in battles and also contribute to the growth of the ninja arts in the village.
There could also be a storyline where Naruto and the Kyuubi team up to face a common enemy that neither of them could defeat alone. They have to rely on each other's strengths, with Naruto's determination and the Kyuubi's raw power. This adventure would bring them closer as friends and show the world that they are a force to be reckoned with.
Another plotline could involve time - travel in the fanfiction. Naruto and his friends could be sent back in time to the era of the First Hokage. There, they would have to adapt to the different ways of the past while also trying to figure out how to get back to their own time, and in the process, they might change the course of ninja history.
