Well, in fanfiction, when Darth Vader meets Yoda, it could lead to a battle of ideologies. Vader, having turned to the dark side, represents power and control through the Sith ways. Yoda stands for the Jedi's connection with the Force in a more harmonious and selfless way. They could engage in a Force - powered duel where Vader tries to overpower Yoda with his dark side strength, but Yoda uses his wisdom and experience to counter.
In a 'Ahsoka meets Darth Vader' fanfiction, there could be an intense battle. Ahsoka, with her Jedi skills, would be a formidable opponent to Vader. Maybe she tries to redeem him, recalling the Anakin she once knew. Or perhaps Vader sees her as a threat to the Empire and attempts to eliminate her quickly.
Perhaps Vader would start with 'You cannot stop me, old one.' Yoda would then calmly say 'Not so, young Skywalker. The Force is with me.' This shows the contrast between Vader's arrogance in the dark side and Yoda's confidence in the light side of the Force. There could also be a moment where Vader asks Yoda why he should return to the light, and Yoda gives a long speech about the true nature of the Force and how the dark side is a path to self - destruction.
Well, in such a fanfiction, R2D2 could use his beeps and whistles to communicate something unexpected to Darth Vader. It could be some long - forgotten information about Anakin Skywalker that makes Vader question his path. And Vader might find himself hesitating to harm the little droid because of this new - found knowledge.
In such a fanfiction, one possibility is that Anakin Skywalker might initially be in shock upon seeing Darth Vader. He could struggle to come to terms with what he has become. Maybe there would be a battle of wills as Anakin tries to fight against the dark side within Vader.
In fanfiction, when Darth Vader meets his grandchildren, there could be a moment of shock and confusion. His dark past might contrast sharply with the innocence of his grandchildren. Maybe he would initially be feared by them, but as time passes, he could show a side of him that was long buried under the Vader persona, a side that is capable of love and protection.
He might try to change his own fate. For example, he could prevent himself from turning to the dark side in the first place. Maybe he would warn his younger self about Palpatine's true intentions.
Well, one possibility is that Ahsoka tries to redeem Vader. She might see a glimmer of Anakin still in him and strive to bring him back to the light side. It would be a very emotional encounter, full of memories of their past as master and apprentice.
Well, it could be a really wild story. Harry's magic might interact in strange ways with Darth Vader's Force powers. Maybe Harry would try to use his spells to resist Vader's dark side influence.
He might be interrogated by the captors. They could try to extract information about the Sith, the Empire's secrets, or his own powers. Maybe they would attempt to turn him against the Emperor, using various means like appealing to his remaining humanity or threatening him with things he values.
Well, in this fanfiction scenario, Grogu and Yoda's meeting could be filled with wisdom - sharing. Yoda might teach Grogu some advanced Force techniques. Maybe he'd show Grogu how to better control his levitation skills or how to communicate more clearly with other Force - sensitive beings. Grogu, on the other hand, could show Yoda his unique way of using the Force that he has developed during his time with Din Djarin.
