I'm not entirely sure as there could be many interpretations. It might be a fan - made story that involves a unique fighting style or technique related to Naruto, perhaps a new form of the 'ninth fist' that the author has created within the Naruto universe.
I don't know specifically as it depends on the fanfiction. It could be Naruto and his friends if the 'ninth fist' is something they encounter or develop.
A great fanfiction concept would be a crossover where Naruto is taught the art of the fire fist by a character from another anime. This could lead to new and exciting battles as he combines his existing skills with the new fire fist power.
The unique concept of a 'thousand - fist' technique is what makes it interesting. It gives Naruto a fresh and powerful ability that sets these fanfictions apart from the regular Naruto stories.
Sometimes, an original character created specifically for the fanfiction could be a main character. This character could be a mentor - like figure who teaches Naruto about the dragon fist. They might have a deep knowledge of the technique's origin and its true potential, guiding Naruto on his journey to master it.
There could be a fanfiction where the Naruto Fist is combined with other elements not seen in the original series. For example, a story where the Naruto Fist is infused with the power of a long - forgotten spirit, allowing for new and powerful attacks. This could lead to a whole new adventure for the main characters as they face an enemy who can also manipulate such powers.
Naruto himself is often very popular in 'Naruto Fist' fanfiction. Since it's related to a technique named after him, writers like to explore new aspects of his character in relation to this. He might be shown teaching others the Naruto Fist or coming up with new variations of it.
One unique feature is the new combat style. The Shredding Fist offers a different approach to fighting compared to the traditional Naruto jutsu. It can be more brutal and direct.
One common theme is power enhancement. Writers often explore ways to make the Gentle Fist more powerful. Another is legacy, like how the technique is passed down through generations.
Maybe Tsunade. She is known for her love of sake. She could have some hidden knowledge of the Drunken Fist. Since she is also a very powerful ninja, she could train Naruto in both the physical and strategic aspects of the Drunken Fist. She could show him how to use his chakra more effectively while performing the drunken - like maneuvers.
