Luke Skywalker could be another key character. Since he is Vader's son, his presence could add an interesting dynamic. He might be the one who somehow triggers the battle between Anakin and Vader, or he could be in a position to influence the outcome of their fight, perhaps by appealing to the remaining good in Anakin or by facing off against Vader himself in a three - way struggle.
Darth Vader could encounter advanced droids that have developed personalities and even some form of Force - like abilities in this future. These droids might be a new challenge for him as they are not like the droids he is used to dealing with in his own time. He may also meet future versions of his former allies or enemies, who have been reincarnated or cloned in some strange new way, with different personalities but still with a connection to their past selves.
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.
A possible fanfiction could involve a fusion of their powers. For example, Naruto discovers a way to combine his chakra with the strange energy that Darth Nihilus wields. This new power could be used to either save the world from a greater threat or to bridge the gap between the two universes. Or perhaps Darth Nihilus, in his search for power, tries to steal Naruto's chakra, but Naruto's bond with his friends and the Nine - Tails gives him the strength to resist and turn the tables on Darth Nihilus.
In such a fanfic, the Avengers' diverse powers would clash with Darth Vader's formidable Force abilities. Iron Man could use his high - tech suits to try and outmaneuver Vader's lightsaber attacks. Captain America might lead the charge with his shield against Vader's dark side - enhanced combat skills. It would be an epic battle of good from different universes against Vader's Sith - influenced evil.
It really depends on how you write it. If it's Anakin at his peak before turning to the dark side, he has a lot of raw power and potential. But Vader has years of experience as a Sith Lord. So, it could go either way.
In fanfiction, we can also see how an OC might change the power balance between Vader and Sidious. If the OC is a powerful ally to Vader, it could lead to a split in the Sith order. Or if the OC is a double - agent working for both, it can create a complex web of lies and deceptions that make for a very engaging read.
One great aspect of fanfiction involving Darth Vader, Darth Sidious and an Original Character (OC) is the potential for new storylines. For example, an OC could be a Jedi who manages to infiltrate the Sith ranks, interacting with Vader and Sidious in unexpected ways. This could lead to intense power struggles and moral dilemmas within the story.
Darth Vader could meet advanced droids that have personalities and abilities far beyond what he's used to. These droids might see him as a relic from a bygone era. He could also meet future scientists who are intrigued by his cybernetic enhancements and try to study him. Additionally, there's a chance he meets descendants of his former allies or enemies, which would create a complex web of relationships and interactions.
