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.
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.
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.
A fanfiction could explore the idea of Darth Sidious being somehow trapped in the Harry Potter universe. He'd be completely out of his element, yet still a formidable threat. Harry Potter, with his knowledge of the wizarding world and his courage, would be the one to stand up to Sidious. This could lead to a unique mentorship situation where Dumbledore tries to understand the nature of the Force from Sidious in order to find a way to defeat him, while also teaching Harry how to resist the Sith's temptations.
One idea could be a what - if scenario where Anakin in his pre - Vader state somehow gets a glimpse of his future as Vader. He could then fight against the dark side within himself that would turn him into Vader. Another could be a time - travel plot where Vader is sent back to face Anakin, and Anakin has to decide whether to accept his possible future or fight against it.
Well, Naruto would probably become extremely powerful in the dark side of the Force. His ninja skills combined with Sidious' Sith teachings could make him a force to be reckoned with. He might lose some of his original moral compass though, as Sidious is all about power and domination.
In a fanfiction where Harry fights Darth Sidious, it could go in many ways. Maybe Harry uses his magic skills like the Patronus charm to fend off Sidious' dark side Force attacks. Since Harry has shown great courage and quick thinking, he might be able to hold his own against Sidious at first. But Sidious is extremely powerful in the Dark Side of the Force. So, it would be a tough battle and perhaps Harry would need to find some way to disrupt Sidious' connection to the Force, like using magic to create interference.
