In this fanfiction, Naruto could use a scythe that has a transformation ability. It could start out as a small, easily - concealable weapon and then transform into a large, menacing scythe when he's ready to fight. The scythe might also be decorated with symbols of his village or his family, like the Uzumaki swirl, to give it a personal touch.
He might use a scythe with a chakra - infused blade. This would give it an extra edge (literally) in combat, allowing it to cut through tougher materials. The scythe could also have some sort of sealing mechanism on it, similar to his kunai, so he could store small items or even chakra - based attacks within it for surprise strikes.
Perhaps Naruto would use a scythe that has some unique abilities related to his own powers. For example, it could have the ability to absorb and then release chakra in a different form, like converting his normal chakra into a more destructive or healing energy. The scythe could also be made of a special material that is resistant to certain types of attacks, such as genjutsu - based attacks, so that it doesn't get affected when he's in the middle of a fight.
Well, he might incorporate more acrobatic moves. The scythe is a large and unwieldy weapon compared to his usual ninja tools. So he'd probably have to be more fluid in his motions, using spins and wide arcs to attack. He could also use his ninja skills like chakra control to enhance the power of his scythe strikes, for example, coating the blade with chakra for a stronger cut.
One potential character could be Sasuke. Imagine in a dark, alternate universe fanfic where Sasuke, instead of using his sword, wields a scythe. It could be a symbol of his more menacing and reclusive nature. He might use it with his Sharingan abilities, making his strikes not only powerful but also unpredictable as he can anticipate his opponents' moves.
One possible plot could be that Naruto discovers an ancient scythe during one of his adventures. This scythe could be imbued with some sort of special power, like the ability to cut through any chakra - based defense. Naruto then has to train to master using this scythe, which is a completely different weapon from his usual ninja tools. He might face challenges as his friends and the village elders are skeptical about him using such an unorthodox weapon.
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.
I'm not sure of a specific fanfiction where Naruto uses a scythe off the top of my head. But you could try searching on fanfiction - specific websites like Archive of Our Own or FanFiction.net. Use keywords like 'Naruto' 'scythe' in the search bar to find relevant stories.
It would likely add a new dimension of reach. Naruto could use the scythe's long handle to keep opponents at a distance. And since it's sentient, it might be able to anticipate an opponent's moves and guide Naruto's strikes more effectively.
The origin could be some ancient, long - forgotten magic. Maybe it was created by a powerful and now - extinct clan. They might have imbued it with a spirit or some form of intelligence for a specific purpose, like protecting a hidden treasure or an important location.
It could be really cool. Naruto might use the death scythe in combat, slicing through enemies with ease. The scythe could have some unique abilities, like draining the chakra of those it cuts. It would change the dynamics of his battles.
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.
One possibility is that the scythe is a key element in a prophecy. Naruto, as the main character, is fated to find it. With this scythe, he could gain new allies who are also interested in its power. However, he would also face new enemies who want to take the scythe from him. This would create a lot of tension and action in the fanfiction.
