The fanfic might start with Ahsoka learning of Vader's continued existence and her decision to try and turn him. This is an important plot point as it drives the whole story. Then, as she gets closer to Vader, there could be a series of confrontations where she chips away at his dark side. These encounters are key plot points. Finally, the climax would be Vader fully embracing the good again, which is the ultimate plot point that the whole story has been building towards.
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.
One key point is the young smuggler arriving on Mustafar. Another is facing Vader directly. Also, the exploration of Vader's experiments with the Force.
One plot idea could be a time - travel scenario where Ahsoka is sent back in time and has to face Darth Vader before he fully became the Sith Lord she knew. She could try to prevent his fall. Another idea is a story set in an alternate universe where Ahsoka and Vader team up against a greater threat, forcing them to put aside their differences. Maybe a plot where Ahsoka is captured by Vader and he has an internal struggle about what to do with her, given their past relationship.
She might start by becoming disillusioned with the Jedi Order. Maybe she discovers some secrets that make her question their ways. Then, she could be lured by the power the Dark Side offers, like Darth Vader was. She'd likely start using more aggressive and unethical tactics in combat and in her relationships.
One possible plot could be a story where Darth Vader, in his full potential, has a moment of self - realization during a battle against Ahsoka. He might start to question his dark path and Ahsoka, seeing this glimmer of Anakin in him, tries to pull him back to the light. It could be a complex emotional journey for both characters as they grapple with their past relationship as master and apprentice.
A plot could involve Ahsoka trying to redeem Darth Vader. She might attempt to reach out to the Anakin Skywalker she once knew, and through a series of encounters, Vader starts to question his path in the dark side. For example, they could be forced to team up against a common enemy, like a new Sith Lord who wants to destroy them both. This situation would put Vader in a position where he has to choose between the Sith teachings and his old friendship with Ahsoka.
One great 'Ahsoka Vader fanfic' is 'The Meeting'. It delves into a possible encounter between them, filled with tension and unspoken history. Another good one could be 'Ahsoka's Choice' which explores how Ahsoka might react to facing Vader, her former master in a new, dark form.
Yes, there are likely some fanfics with this concept. Fanfic writers often explore unique and alternative storylines. They might be interested in exploring what would happen if Ahsoka, who was Anakin Skywalker's apprentice, ended up in a situation where she worked for Darth Vader (Anakin's Sith persona). It could involve complex character dynamics and a re - imagining of the Star Wars universe.
One good 'Vader protects Ahsoka' fanfiction could be where Vader has a moment of clarity about his past with Ahsoka and decides to shield her from the Emperor's wrath. Maybe he secretly diverts Imperial forces that are after her.
Well, in this kind of fanfiction, a major plot point is often the moment of transformation itself. Alucard might use his powers in a particular way to turn Seras. Also, the way other characters react to Seras becoming a vampire can be important. Some might be afraid, while others might see it as an opportunity. And of course, Seras's own internal conflict about her new state is a central plot point.
