He could become a weapons master through some kind of special power-up. For example, a new chakra form that gives him an affinity for weapons. He might be able to infuse his chakra into weapons, making them more powerful. And Naruto is known for his hard work, so he'd surely spend countless hours training with various weapons, from swords to shurikens, until he masters them.
He could start by training intensively with different weapons under the guidance of some old and experienced ninja. They might teach him the proper techniques and stances for using each weapon effectively.
Well, in some fanfictions, Naruto might obtain the Master Sword through a strange portal that connects his world to the world where the Master Sword exists. Maybe he's on a mission and stumbles upon it by accident.
Sasuke could be one. Since they have a long - standing rivalry, Sasuke, with his own powerful skills, would be a great opponent for Naruto now that he's a master swordsman. They could have an epic battle where sword meets sword and their respective powers clash.
In this fanfiction, Naruto could master shurikens in a new way. Instead of just throwing them, he could learn to control their flight path precisely with his chakra. Another weapon he might master is the naginata. It's a long - handled weapon that he could use to keep enemies at a distance while also delivering powerful blows.
In the Naruto world, the concept of a poison master fits in as a unique form of combat specialization. Just as there are ninjas who are experts in taijutsu, genjutsu, or ninjutsu, a poison master uses poisons as their main weapon. They can create poisons that can paralyze, kill, or even disrupt chakra flow. This adds another layer of danger and strategy to the battles in the Naruto universe.
Yes, there are likely fanfictions out there where Naruto is depicted as a poison master. Fanfiction writers often like to take established characters and put them in unique and unexpected roles. They might explore how Naruto's skills and personality could be adapted to the role of a poison master, perhaps using his knowledge of herbs from his time in the forest or his ninja stealth to create and administer poisons in a creative way.
If Naruto were a master of the force in fanfiction, it would change the whole Naruto universe. He might be able to levitate and move objects with ease, which could be a huge advantage in battles. His rasengan could be infused with the force, making it an even more devastating attack. And he could potentially use the force to communicate with others telepathically, adding a new dimension to his relationships with his friends and allies.
Well, it depends on the specific fanfiction. There are countless fanfictions out there, and while many might explore the idea of Naruto as the master of Caster, others may not. Some fanfic authors like to create unique power dynamics and relationships, and this could be one of them. However, not all fanfictions will follow this concept.
