One interesting plotline could be Anakin's struggle with his past self as Vader. Maybe in the fanfic, Anakin tries to prevent Vader from making the same mistakes he did, leading to intense battles of will and lightsaber duels.
Perhaps a plotline where Anakin and Vader are forced to team up in some strange alternate reality. They have to put aside their differences and work together, which would be full of tension as they both have very different outlooks due to their different states of being.
In some fanfics, there might be a plotline where Palpatine tries to corrupt Anakin even further during the battle, using psychological warfare. Anakin, on the other hand, has to resist this while also fighting for his life. This adds a layer of psychological drama to the physical fight between them.
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.
One interesting plotline could be a battle that takes place in an alternate universe where Anakin and Obi - Wan have different allegiances from the start. Maybe Anakin is a Sith Lord right from the beginning and Obi - Wan has to face his former apprentice in a more cut - throat battle.
Well, obviously Anakin and Vader are the main characters. Anakin is his pre - Darth Vader self, full of potential and hope at one point, and Vader is the dark, powerful Sith Lord he becomes.
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.
A fan fiction could also explore a parallel universe where Anakin and Darth Vader are two separate entities that co - exist. They are forced to fight not because of Anakin's fall, but due to some external force that wants to see the two most powerful Sith - like beings battle it out. This could lead to an exploration of their different fighting styles and the power dynamics between them.
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.
One interesting plot point could be the power struggle between Anakin and Clovis. Anakin is a powerful Jedi, while Clovis is often involved in political and economic affairs. Their clash might involve different ideologies, with Anakin representing the Jedi way and Clovis perhaps having more self - serving motives. Another aspect could be a love triangle situation if there is a female character involved who has connections to both of them, which would add a lot of drama and tension to the story.
Here are some plot ideas. Imagine a fanfic where Padame is resurrected by an ancient Force power. She then disguises herself and infiltrates the Empire to be close to Anakin. As she gets closer to him, she starts to bring back his memories of their love. For Luke and Leia, they could be on a quest to find a powerful Jedi artifact that was once owned by their mother. Along the way, they face many challenges and have to use their combined skills. Another idea is a fanfic set in an alternate universe where Anakin never turned to the dark side. He, Padame, Luke, and Leia all live together as a happy family, and they are on a mission to spread peace and justice across the galaxy.
One interesting plotline could be Deku having to face off against his classmates in a series of challenges that test not only their quirks but also their teamwork and strategic thinking. Maybe there's a misunderstanding that leads to the conflict.
