Maybe a mysterious traveler from a far - off land. This traveler has mastered many unique jutsus including Dust Release. He crosses paths with Naruto during one of Naruto's solo adventures and takes him under his wing after seeing Naruto's eagerness to learn new techniques.
Yes, in some fanfics Naruto might be depicted using Dust Release. Fanfic writers often take creative liberties and can give Naruto abilities that he doesn't have in the original series, like Dust Release, to make the story more interesting or to explore different plotlines.
There's a possibility that it's a spirit or a deity in the world of bending. This entity is impressed by Naruto's tenacity and chooses to guide him on his journey of learning bending.
A traveling nen master could be Naruto's mentor. This master could be on a journey to spread the knowledge of nen. He crosses paths with Naruto and decides to teach him. The master might have a strict teaching style, pushing Naruto to his limits, but also guiding him carefully through the complex world of nen.
It could be Kakashi. Even though in the original story he doesn't teach Naruto the Rasengan, in a fanfic he might have some hidden knowledge about the technique. Maybe he was secretly studying it himself and saw Naruto's eagerness to learn new jutsu, so he decided to share his knowledge and help Naruto learn the Rasengan earlier.
The implications are quite extensive. Firstly, from a combat perspective, Naruto's fighting style would likely change drastically. He would have to adapt to the unique properties of Dust Release, which could involve different hand signs and chakra control. Secondly, in terms of the overall story, it could shift the focus of the fanfic. Instead of relying on his typical Rasengan or Sage Mode, the plot might revolve more around his new Dust Release ability. This could lead to new alliances and rivalries as other characters react to his newfound power. It also might attract different types of enemies who are interested in either obtaining or countering his Dust Release.
Often, characters like Ohnoki are popular in Naruto Dust Release fanfic. Since he is one of the known users of Dust Release in the original series, fanfic writers like to expand on his story or his abilities related to it. Another could be a new OC (Original Character) that the writer creates specifically to be a master of Dust Release.
One implication is that he becomes even more powerful. Dust Release can be used in various combat situations, so it gives Naruto an edge. For example, he could use it to quickly take out multiple enemies at once.
Kakashi could be a great mentor. Since he was Minato's student, he has first - hand knowledge of Minato's techniques. He could teach Naruto the fundamentals of the Yellow Flash's fighting style, like how to control chakra for high - speed movement.
Maybe he discovers some ancient scrolls that detail the secrets of Dust Release. Naruto, being the determined ninja he is, spends countless hours deciphering the scrolls and practicing the techniques described, until he finally gets a grip on the Dust Release.
Well, one possibility could be that Naruto acquires the Dust Release ability through some sort of encounter. Maybe he meets an old sage who imparts this unique power to him. Then he has to learn to control it, which could be a whole new arc in the story. He might struggle at first, but as Naruto always does, he'd persevere and eventually master it, using it to defeat new and powerful enemies.
