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.
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.
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.
He could inherit the power of Force lightning. Darth Sidious was known for his powerful Force lightning attacks. In the Naruto universe, this could translate to some sort of unique chakra - based lightning attack that is far more powerful than the normal lightning - style jutsu. Also, Naruto might inherit some telekinetic abilities, being able to move objects with his mind or chakra, similar to how Sidious could use the Force for telekinesis.
Well, if Naruto were the grandson of Darth Sidious in this fanfiction, it would likely bring a dark and different dynamic to the Naruto universe. Naruto's typically positive and bright nature might be conflicted with the Sith influence from Darth Sidious. His values of friendship and hard work could be challenged as the Sith ways are more about power and domination. It could also change the power balance in the Hidden Leaf Village as Naruto might have access to different, perhaps more sinister powers, which would make his fellow ninjas view him differently.
Well, a great fanfiction idea could be that Darth Sidious discovers the existence of the wizarding world through some dark magic connection. He decides to conquer it, thinking it would be easy prey. But he underestimates the power of the Hogwarts students and their loyalty to each other. Harry Potter would be at the forefront of the resistance, using his skills and the support of his friends like Hermione and Ron.
One idea could be a crossover where Darth Sidious discovers the world of Naruto and tries to manipulate the ninja politics for his own gain. He might see the chakra system as a new source of power to exploit.
One interesting plot twist could be that Darth Vader is actually related to one of the Avengers in some way. Maybe there's a long - lost family connection that changes the whole dynamic of the fight. Another could be that the power source of the Infinity Stones somehow combines with the Force, creating a new and unexpected power that either Darth Vader or an Avenger has to control. It could also be a plot twist where the Avengers think they've defeated Vader, but he actually uses a Sith technique to possess one of them and turn the tables.
