One interesting plot could be Naruto having a secret power that he discovers during a new and dangerous mission outside the Hidden Leaf. This power might be related to an ancient jutsu that only he can unlock due to his unique chakra nature.
Perhaps a plot where the 'monster of the leaf' is actually a misunderstood being. It could start as an outcast but then as the story unfolds, it turns out to be a key figure in saving the leaf village from a great threat. Maybe it has some hidden knowledge or power that only gets revealed in the most crucial moments.
Obviously, Naruto himself is always a popular character. His determination and growth throughout the story are always interesting to explore further in fanfiction.
One idea could be exploring the backstory of the demon more in - depth. Maybe it has a connection to an ancient clan in the Hidden Leaf. Another could be the demon possessing Naruto and how he struggles to control it while his friends try to save him.
In some naruto hero water fanfiction, there could be a plot where the water has a connection to an ancient prophecy. The hero, unknowingly, is the one fated to either master the power of this water or destroy it to prevent it from falling into the wrong hands. This can lead to a journey of self - discovery for the hero as they learn about their role in the grand scheme of things.
Well, one interesting plot could be how the main character manages to balance his relationships with different members of the harem while also dealing with the challenges in the Naruto world. For example, he might have to protect his harem from enemy ninja attacks.
A cool plot twist could be that the Hidden Leaf Village is not actually in danger in the way it seems. It's all a big illusion created by a powerful enemy to make Naruto use up all his strength. Once Naruto realizes this, he has to find a way to break the illusion for everyone in the village and then face the real enemy, who is waiting for Naruto to be weakened.
One interesting plot could be that Naruto discovers his hidden bloodline gives him the ability to control time in small increments. This allows him to dodge attacks more easily and plan his counter - attacks more effectively.
There might be a fanfiction where Naruto discovers a long - hidden secret within the Leaf Village that leads to a bloody internal conflict. This could involve different ninja clans having opposing views and Naruto being caught in the middle, trying to restore peace while facing his own friends and comrades as adversaries. It would be a story full of drama, action, and moral dilemmas.
Well, it could be interesting in terms of the writing style. If leaf is good at descriptive writing, then the fanfiction might vividly bring to life the ninja world of Naruto. For example, the battles could be described in great detail, making the readers feel as if they are right there in the action. Also, it might explore the backstories of minor characters more deeply, adding more depth to the Naruto universe.
One interesting plot could be the emergence of a new and powerful villain. This villain has unique powers that the heroes in the academy have never faced before, forcing them to develop new strategies and teamwork skills.
