Let's say he gets a weapon that can transform. For example, it can change from a small dagger to a large spear. This would make his combat style more versatile. He could start a fight with the dagger form for quick, sneaky attacks, and then transform it into a spear when he needs more power and reach. This new weapon would force him to learn new fighting techniques and adapt his style to make the best use of its abilities.
Well, he might get a chakra - enhanced katana. It could be really cool as it can cut through almost anything with the added chakra power.
In some Wave - related fanfictions, Naruto might find a unique sword. It could be a sword with special powers like being able to cut through almost anything. Maybe it has some sort of chakra - enhancing property.
The scythe might make Naruto's combat style more aggressive. He could use it for long - range attacks and quick slashes, adding a new dimension to his fighting. For example, he could combine his shadow clone jutsu with scythe attacks, having clones distract the enemy while he swoops in with the scythe.
Yes, sometimes he finds a rare dagger. This dagger might have a special symbol on it that gives it a connection to an ancient clan in the Wave region. It could hold secrets or powers related to that clan.
Perhaps it was a weapon created by a rogue ninja with unique powers. And for some reason, it found its way to Naruto in Wave. It might also be a weapon that was enchanted by a sorcerer long ago and has special abilities that Naruto will discover as he uses it.
If Naruto got a new bloodline in the fanfiction, it could strengthen his relationship with Sasuke. Sasuke, always interested in power, might be intrigued by Naruto's new abilities and see him in a new light. They could start training together again to understand and master the bloodline, which would bring them closer as friends and rivals.
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.
In this fanfiction, Naruto might also create a shield. This shield could be made from a combination of rare materials he discovers during his adventures. It has the ability to not only block physical attacks but also absorb and redirect chakra - based attacks back at the enemy.
His relationship with Sasuke would be greatly affected. Sasuke might see Naruto as more of an equal in terms of their eye powers. They could have a new level of understanding or even rivalry. It might also make Sasuke more protective of Naruto in a strange way, since the Sharingan is precious to the Uchiha.
One way is to base the weapons on existing ninja tools in the Naruto universe. For example, you could create a modified version of the kunai, like a kunai with a hidden blade that can extend for surprise attacks. Another idea is to draw inspiration from nature. Maybe a weapon made from a special tree in the Hidden Leaf Village that has unique properties, such as being able to absorb chakra.
