Well, it might have a plot where Naruto has to break a cycle related to Samsara. For example, a cycle of past mistakes or events that keep repeating in the ninja world. He could use his determination and newfound understanding to change things.
One interesting plotline could be about Naruto exploring an alternate universe within the Samsara concept. Maybe he discovers new powers or meets different versions of his friends.
There are also fanfictions that involve the Samsara in relation to the tailed beasts. Maybe a story where the tailed beasts are actually ancient beings trapped in a cycle of samsara and Naruto has to find a way to break that cycle for them. This could lead to some really interesting character development for Naruto as he tries to free these powerful creatures from their eternal loop.
A possible plotline is a gender - bent Naruto having to prove herself in a male - dominated ninja society. She could form an all - female ninja team and take on missions that are typically thought to be for male - only teams. This would show her strength and determination in a different light compared to the original Naruto story.
One interesting plotline could be about Naruto unlocking a new and extremely powerful form in the 'naruto fury fanfic'. This form might be a result of his intense fury and determination, allowing him to face off against enemies he couldn't before.
One interesting plotline could be Naruto coming back reanimated and having to face new enemies that his old friends can't handle alone. His reanimated state might give him unique powers or abilities that change the course of battles.
One interesting plotline could be the exploration of Onikage's backstory within the Naruto universe. Maybe he has a hidden connection to a powerful clan that was long forgotten.
One interesting plotline could be the exploration of the unique culture and history of the Mist Village within the fanfic. Maybe it delves into the training methods of Mist ninjas that are different from other villages.
One interesting plotline could be Naruto's discovery of new and powerful sealing techniques. He might use these to defeat enemies in unique ways, like sealing away their chakra sources. For example, he could develop a seal that can nullify the effects of a powerful jutsu by sealing the energy that fuels it.
Perhaps Naruto controls Zetsu to help him in battles. Zetsu could act as a distraction while Naruto sets up his more powerful jutsu. For example, Zetsu could split into multiple forms and confuse the opponents, giving Naruto an opening to attack.
One interesting plotline could be Naruto adjusting to civilian life after retiring. He might struggle with the boredom of not having the constant action and purpose he had as a shinobi. Another could be him mentoring the next generation in a more laid - back way, passing on his wisdom without the pressure of active duty.
Perhaps there's a plotline where the other Jinchuuriki are in danger and Naruto has to rescue them. Since Naruto has a strong sense of justice, he would not hesitate to step in. This could lead to some intense battles and also show Naruto's growth as a character. He might use new jutsu or strategies he has learned along the way.
