There's a fanfic titled 'Vader's Redemption'. In this story, Vader starts to question his loyalty to the Emperor much sooner, especially after some profound encounters with Luke. It's a great read as it shows the internal struggle of Vader while also exploring the bond between father and son in a new light. It's full of action-packed scenes and deep emotional moments.
This would be a huge twist. It might mean Luke is seduced by the dark side's power or has some ulterior motive for joining Vader. It could change the course of the entire story.
One reason could be that Vader represents the dark side which has brought so much destruction in the galaxy. Luke, being on the side of the Jedi and good, would naturally despise the evil deeds associated with Vader.
Often through his internal thoughts. The fanfiction might describe Luke seething with anger whenever he thinks of Vader. For example, in some stories, when Luke is meditating, his thoughts are constantly interrupted by visions of Vader and his past actions, and he can't focus because of his hatred.
In some fanfiction, if Luke and Darth Vader teamed up, they could be an unstoppable force for good. They could use their combined Force abilities to fight against a greater evil in the galaxy. Maybe they would start by taking on the Emperor together, using Vader's knowledge of the Sith and Luke's purity in the Force.
The relationship could develop in a complex way. Since Vader has captured Luke, there's a power imbalance. However, as they interact, Luke might try to reach out to the good in Vader. Vader, in turn, might be conflicted. He could start to protect Luke from the Emperor's harsher plans, leading to a strange alliance within the captivity.
Vader might initially be shocked. His son reaching out to him is unexpected. He could respond with a moment of silence, trying to process what is happening.
One great fanfic could be 'The Redemption of Vader and the Ascent of Luke'. It delves deep into the relationship between the two. It shows how Luke's unwavering belief in the good in Vader starts to chip away at Vader's dark side. It's filled with intense lightsaber battles and emotional dialogues that really capture the essence of their connection in the Star Wars universe.
Another good one is 'Luke and Vader: The Untold Adventures'. This fanfiction takes the two on a series of adventures that were not part of the main Star Wars story. They face new enemies and challenges, and in the process, their relationship evolves in ways that are both unexpected and exciting. It really shows the potential of their relationship outside of the main plot.
One key theme is redemption. Darth Vader's journey from the dark side back towards the light is often explored. For example, in many fanfics, Luke plays a crucial role in bringing out the good in his father. Another theme is family. Despite the dark and light divide, they are still father and son, and this complex family dynamic is a major part of the stories.
