When Luke witnesses Vader's fall, his view of Vader could shift towards a more nuanced understanding. He might think about how Vader was once Anakin Skywalker, a Jedi with great potential. The fall could be a symbol for Luke of how easily one can be corrupted. He may also feel a sense of responsibility to make sure that such a thing doesn't happen again in the galaxy, and perhaps be more vigilant about the spread of the dark side.
His view could become more complex. Before, Vader was mainly an enemy. But seeing his fall, Luke might start to see him more as a tragic figure, a victim of the dark side's power.
Luke may see Vader in a more sympathetic light. The fall could make Luke realize that Vader was not just a powerful Sith but also a broken man. He might understand that Vader's actions were not entirely his own, influenced as he was by the Emperor and the dark side. This could lead Luke to re - evaluate his own understanding of good and evil in the Star Wars universe.
In certain fanfictions, Luke sees Darth Vader's fall symbolically. For example, he might see the destruction that Vader has caused on a planet or to a group of people. This destruction represents Vader's fall from grace. It could be that Vader has ordered the massacre of innocents, and Luke witnesses the aftermath. This makes Luke realize the true nature of the dark side that Vader has embraced and how far he has fallen from being a Jedi.
Luke might be initially shocked. He has always seen Vader as this powerful and menacing figure. So, seeing him fall could bring a sense of disbelief. It could also stir mixed emotions in Luke, like a strange form of pity despite all the bad things Vader has done.
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.
One theme could be redemption. Seeing Vader's fall can symbolize his redemption from the dark side, and Luke witnessing it can be about the power of forgiveness and the possibility of change in the Star Wars universe.
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.
A good fanfic about Luke and Darth Vader should first and foremost have a strong understanding of the characters. They need to stay true to their personalities as seen in the movies. For example, Vader's internal struggle between the light and dark side should be well - represented. Also, a great plot that ties into the existing Star Wars mythology is important. Maybe it could involve a new threat that forces Luke and Vader to work together, or explore their relationship in a different time period.
In many such fanfictions, their relationship becomes more positive. Vader starts to see Luke as a chance for true redemption. He may become more of a mentor to Luke, sharing his knowledge of the Force.
Luke could react with a newfound sense of responsibility. Seeing Vader's fall, he might feel that it is his duty to help any other fallen Jedi or those who are on the brink of falling to the dark side. He might also have a moment of self - reflection, wondering if he could ever be tempted by the dark side in the same way Vader was.
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.
His presence could change the power balance. If he sides with the Jedi, the Sith would be at a disadvantage. The Sith rely on secrecy and manipulation, but with Darth Vader knowing their plans, they would be exposed more easily.
