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.
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.
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.
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.
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.
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.
In 'revan vs vader fan fiction', often we can expect epic battles. Revan, a powerful figure from the Old Republic era, and Vader, the iconic Sith Lord from the Galactic Empire. Their combat would be a clash of different Sith ideologies. Revan might bring the ancient knowledge and skills of the Old Republic, while Vader would have the might of the Emperor behind him. It's a fascinating concept for fans to explore.
One idea could be a story that focuses on Anakin's internal struggle between his love for Padme and his fall to the dark side as Darth Vader, while Luke and Leia unknowingly grow up in the shadow of their father's actions. It could explore how their lives might have been different if Anakin had not turned, and how they eventually come to terms with his true identity.
In some fanfics, Anakin's turn to Vader during the Clone Wars might be accelerated by a series of events that test his loyalty more severely. For example, he could be framed for a crime against the Jedi Order. This false accusation could make him feel betrayed by the very people he has sworn to serve. As a result, his connection to the dark side could strengthen as his anger and confusion grow.
