Well, there are many possibilities. Naruto could find that his vizard powers allow him to communicate with spirits in a new way, which could help him in his ninja missions. He might also face internal conflicts as the Hollow part of him tries to take over during intense battles. His vizard powers could attract the attention of powerful villains who want to either control him or steal his powers. He may have to train with a new mentor who is familiar with vizard powers to fully master them. And perhaps he uses his new powers to create a new type of jutsu that combines ninja techniques with vizard abilities.
Perhaps in this fanfiction, Naruto is an alpha in terms of his social standing among the ninja villages. He could be the one who always gets the first pick of missions and resources because of his alpha status. Also, in his relationships, he might be more dominant. For example, in his friendship with Sasuke, he could be the one who always makes the final decisions on their joint adventures.
Maybe Naruto gets sent to a far - away land by some mysterious force and has to find his way back. This could involve him facing new enemies and making new allies that are completely different from those in the original Naruto story.
In this fanfiction, it could be that Naruto's village is suddenly shrouded in a yami - like mist that brings out the worst fears of the villagers. Naruto has to find the source of this mist and dispel it. Along the way, he discovers that there is an ancient evil that was once sealed away and is now trying to break free through the use of yami - related magic. Naruto has to use his own skills and the help of his friends to stop this evil from being unleashed.
Maybe Naruto can sense a powerful and hidden enemy approaching the village long before anyone else. He could then start preparing the village for the upcoming threat, which would show his importance as a sensor.
Maybe Naruto would use his charm to persuade his opponents to join his side instead of fighting them. For example, he could use his bright smile and positive attitude in a more flirtatious way to win over enemies.
In a group setting within the fanfiction, Hermione could be the one who follows the group's consensus rather than always being the one to drive the ideas forward. Maybe she's part of a magical society where she has to abide by the rules set by those in more dominant positions, and she's in a submissive role in relation to those power structures. This could lead to her having to navigate her own beliefs and desires within the constraints of this sub role.
Perhaps Percy has to compete in Roman gladiator - like games.
Maybe Bella, as a hybrid, can run faster than normal vampires in the story. She could use this ability to save other characters from danger.
Maybe Hermione has a different magical ability that she didn't have in the original. For instance, she could have the power to control time.
The overall world - building in Naruto can lead to fanfic creation. The different ninja villages, their cultures, and politics are rich sources. A fan might write a fanfic about a diplomatic mission between two villages that wasn't shown in the original. Also, Naruto's dreams and ideals, such as his desire for peace, can inspire fanfic writers to create stories about how Naruto tries to achieve peace in different and more complex ways than in the original plot.
