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.
In this fanfic, perhaps Ahsoka might use their past connection. She could remind Vader of the good in him, of Anakin Skywalker. By showing him that there is still a chance for redemption and by appealing to the remnants of his former self, she starts to turn him good.
Vader is very different from the characters in Pulp Fiction. Vader is a powerful Sith Lord in a science - fiction universe. He has superhuman abilities like using the Force. In contrast, the characters in Pulp Fiction are mostly regular humans involved in the criminal underworld. For example, Vincent Vega and Jules Winnfield are just hitmen with no superpowers. They are more about their street - smartness and their complex relationships in the crime world.
Another way is through a connection with his past. Maybe he discovers something about his family, like an heirloom or a hidden message from Padmé. This rekindles his humanity and makes him want to turn away from the dark side. He then uses his skills and power to fight for the right causes, like protecting the innocent and overthrowing the Emperor.
Typically, Vader's redemption starts with a moment of self - reflection. Maybe he witnesses an act of extreme cruelty by the Empire that makes him question his place. Then he begins to reach out to the Light Side, often through small acts of kindness or defiance against the Emperor.
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.
Prometheus' death in the comic is quite a significant moment. It might come from a battle with a powerful villain or due to a twist in the storyline that leads to his downfall.
Well, Geralt might die as a result of a powerful curse or magic. Maybe he angered a powerful sorcerer or witch who cast a spell on him that he couldn't resist. This could be a slow and agonizing death as the magic takes its toll on his body and mind. Another possibility is that he sacrifices himself for someone he loves or to save the world from a great evil. He might put himself in harm's way knowingly, and in the process, lose his life.
Superman's death in comics is often a result of epic battles or selfless acts. For instance, he might face an opponent whose power is just too overwhelming, or he might give his life to prevent a major catastrophe.
