A possible fanfic could involve a fusion of the Force and chakra. Vader discovers the existence of chakra in the Naruto world and tries to combine it with the Force for his own purposes. Naruto and his allies must stop him while also being intrigued by the similarities and differences between the two powers.
There could be. Fanfiction often features unique and unexpected crossovers. Given the popularity of both Naruto and Star Wars, it's not surprising that someone might write a story where Naruto is a fan of Darth Vader. This could lead to some really interesting plotlines, like Naruto being inspired by Darth Vader's power or his complex character and trying to incorporate some of those aspects into his own ninja world.
Yes, there might be. Fanfic websites like FanFiction.net or Archive of Our Own could potentially have such a fanfic. You can search for it using the relevant tags and keywords on these platforms.
One possible plot could be Naruto finding an ancient scroll that tells of a powerful being from another world like Darth Vader. He becomes obsessed with learning more about Vader's power and starts to train in a more aggressive way inspired by Vader.
In a fanfic, perhaps Darth Vader is reborn in the Naruto world as a ninja. He has no memory of his past as Vader at first. As he grows up, he discovers he has strange powers that are different from normal chakra. Eventually, he starts to regain his memories bit by bit and has to decide whether to embrace his Sith past or fully embrace the ninja way of the Naruto world.
In the 'naruto is like darth vader fanfiction', their journey of self - discovery could be seen as similar. Naruto has to constantly figure out his place in the ninja world and how to control his power. Darth Vader is on a journey of self - discovery too, as he grapples with his identity as Anakin Skywalker and his role as Darth Vader. They also have a sense of isolation in some ways. Naruto often feels alone in his struggles, and Darth Vader is isolated in his dark armor, cut off from his former self and many human connections.
The most interesting plot could be that Vader's dark side is slowly purged by Naruto's positive energy. As they interact more, Naruto's belief in the goodness of people starts to chip away at Vader's Sith - like nature. This would be a long and complex journey of transformation for Vader, filled with many internal and external battles as he struggles between his old self and the new person Naruto is trying to help him become.
One way this could happen is through some sort of interdimensional rift. Maybe a powerful jutsu in the Naruto universe accidentally tears open a portal to the Star Wars galaxy. Naruto, being the curious and brave ninja he is, gets sucked into it. Once in the Star Wars universe, he's exposed to the dark side of the Force, which gradually corrupts him and he starts to take on the persona of Darth Vader. He might even learn some of the Sith ways from Vader's own teachings if he somehow travels back in time to Vader's era.
Maybe Naruto gets transported to the Star Wars universe and somehow becomes like Darth Vader. He could start using the dark side of the Force while still having his ninja skills.
Naruto's ability to use chakra and Darth Vader's connection to the Force could potentially create a very powerful combination. For example, Naruto could use his chakra to enhance Vader's lightsaber strikes, making them even more deadly. Or Vader could use the Force to help Naruto better control his Nine - Tails chakra.
