Well, Naruto's determination could be seen as a Sith - like trait. The Sith value power and Naruto is always striving for power to protect his village. He could be a Sith who uses his shadow clones in a more menacing way, like sending them out to do his dark bidding instead of for good deeds.
He would likely become more ruthless. As a Sith Emperor, Naruto would have to make tough decisions that go against his usually kind - hearted nature. For example, he might have to sacrifice some of his friends or allies for the greater good of his empire.
Well, Naruto building the Sith Empire is a wild concept. He might be influenced by a powerful Sith artifact. Imagine he finds a Sith Holocron that shows him visions of great power. His own desire to protect his friends could be twisted. He might think that by ruling through the Sith Empire, he could ensure their safety. He'd then use his charisma, which he had in his own world, to gather people to his cause in the Star Wars universe.
Well, one possible plot could be that Naruto somehow discovers the existence of the Sith in his world. Maybe through a strange portal or some ancient magic. And because the Sith represent such a dark and dangerous force, the village elders or some powerful entity decides to banish anyone associated with them. So Naruto, who might be wrongly accused of having Sith - like powers or being in league with them, is banished. He then has to prove his innocence and fight against the real threat of the Sith - like force that is actually lurking in the shadows.
Well, one possibility could be that Naruto is somehow transported to the Star Wars universe and is neglected by the Sith. Maybe they see him as a weakling at first. He then starts to learn their ways in secret and eventually uses his Naruto - like determination to rise above their neglect and become a powerful force against them.
In a fanfiction scenario where Naruto becomes a Dark Lord of the Sith, he could form his own group of followers. He might use his charisma, which was always a part of his character in the Naruto series, to attract those who are disillusioned with the current ninja system. His Sith powers could give him an edge in combat, making him a formidable adversary. His lightsaber, if he has one in this fanfiction, could be a unique weapon, perhaps modeled after a kunai or shuriken. And he would likely have a new, darker look, with black robes and a menacing presence.
A Naruto character would first have to understand the concept of the Force. For example, Naruto himself might initially struggle as he's used to chakra. But his determination could help him adapt. He might use his skills in combat, like his shadow clones, in a new way within the Sith Warrior framework.
The plot could involve a Sith lord from the Star Wars universe arriving in the Naruto world. This Sith lord sees potential in Naruto and begins to train him in the ways of the Sith. Naruto, initially reluctant, starts to embrace the power as he realizes it can help him protect his village in a different way. But he soon struggles with the moral implications of using dark side powers.
The main antagonist could be a powerful Sith - like figure who has infiltrated the ninja world. This character might be manipulating events from the shadows, causing the village to suspect Naruto and leading to his banishment. They could have their own motives for wanting to take over the ninja world, like using its chakra for their own dark purposes.
The main antagonist could be the Sith Lord who oversees Naruto's neglect. This Sith Lord might be so blinded by the traditional Sith ways that he fails to see Naruto's potential, which in turn makes him the main obstacle for Naruto to overcome.
Naruto's ninjutsu skills could be translated into unique Force abilities for the Jedi and Sith. For example, his Shadow Clone Jutsu could be like a Force - based ability to create multiple illusions or semi - physical clones. This would give the Jedi an edge in combat and deception, while the Sith could use it for more devious purposes like confusing their enemies.
