Star Wars R2D2 and Darth Vader Fanfic: How would their relationship develop in a story?

One plot idea could be that R2D2 is captured by Darth Vader. But instead of destroying the little droid, Vader becomes curious about the information it might hold. He tries to hack into R2D2's memory, leading to a series of tense moments as R2D2 tries to protect the secrets within. Maybe R2D2 has some long - lost Jedi knowledge that Vader thinks could help him overthrow the Emperor.

Darth Vader would probably have a complex reaction. He might feel a sense of familiarity that he tries to suppress. His first instinct could be to destroy R2D2 as it represents a part of his old self that he has tried to forget. But at the same time, he might be intrigued by what the droid could tell him about his past or the Rebellion.

In many fanfictions, their relationship develops in a complex way. At first, it's mainly about the enmity. But as the story progresses, there could be moments of understanding. For example, Vader might see some of his old self in Ahsoka. Ahsoka, on the other hand, might start to pity the broken man that Anakin has become. This could lead to a strange sort of respect between them, even though they are on opposite sides.

In an alternate universe, Darth Vader could be exiled from the Empire after a disagreement with the Emperor. He then stumbles upon Leia on a remote planet. At first, they are enemies, but as they are forced to survive together against various threats on the planet, they start to understand each other. Leia realizes that Vader is not all bad, and Vader sees in Leia a determination that he once had. This understanding could lead to a slow transformation of their relationship from hostility to friendship, and eventually, they could work together to try and bring about a new order in the galaxy, one that is not dominated by the Empire or the Rebellion but a more balanced one.

In some fanfiction, their relationship might develop due to shared goals. Let's say they both want to stop a new superweapon being developed by the Empire. Working together towards this common objective forces them to interact more, and they begin to see each other in a new light. Vader might show moments of vulnerability, which Leia starts to pick up on, and she realizes there is more to him than just the menacing Sith Lord. This mutual discovery helps in building a more nuanced relationship between them.

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 interesting scenario is that R2 uses its charm, if you can call it that for a droid, to make Vader question his loyalty to the Emperor. Since R2 was so close to Anakin, it could show Vader a side of himself that he has long forgotten, and this could make him start to doubt the Sith path he's on.

Well, perhaps Darth Vader would recognize R2 from his past with Anakin. He might initially be hostile but then start to have memories resurface. This could lead to an internal conflict within Vader as he battles between his current Sith self and the remnants of his former self that had a connection to R2.

In fanfiction, their relationship could develop more quickly towards mutual understanding. Maybe Luke could convince Vader to turn away from the dark side much earlier, and they could start training together as Jedi. This would be a huge shift from the original story.
