Luke's meeting with Vader in the comics occurs when Luke stumbles upon a secret operation by Vader. Their interaction leads to a showdown that has significant implications for the story.
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.
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.
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.
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.
I'm not sure exactly, but you can check on dedicated comic book websites or forums for the most accurate count.
It's hard to give an exact number as new Vader comics might be released over time. But as of now, there are quite a few series and issues.
One reason could be to control him. Vader wants Luke on his side, and by locking him up, he can limit Luke's actions and try to influence his decisions.
In this fanfiction scenario, Tatooine's environment is a major player. The deserts are so vast that it's like looking for a needle in a haystack. The sandstorms are not only a hindrance to Vader's search but also a potential cover for Luke. The planet's unique energy fields, which are affected by the binary suns, could distort Vader's ability to sense Luke through the Force. Additionally, the local wildlife and the settlements scattered across the deserts all add to the complexity of the search environment for Darth Vader.
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.
Yes, Luke Skywalker does die in some comic storylines.
