Well, in such a fanfiction, the oc reborn as Anakin could have different relationships. They might not be as easily influenced by Palpatine as the original Anakin was. Since they are a different person inside Anakin's body, they could form new alliances and rivalries. They could also have a different approach to their relationship with Padmé, perhaps being more cautious or open, depending on the nature of the oc.
One way is by focusing on the character development. Since it's an oc in Anakin's shoes, really exploring how they grow and change in the Star Wars universe. Show how they struggle with Anakin's pre - existing relationships and how they make them their own.
In fanfiction, Anakin's character can be expanded through alternate timelines. Let's say a fanfic has him not turning to the dark side. We can then see how his character would have developed as a powerful Jedi without the influence of the Sith. It also allows for exploring his relationships with other characters like the clones in ways that the movies didn't fully cover. Writers can create scenarios where Anakin has to lead the clones in different battles and how that shapes his leadership skills and his view of the war.
One great Anakin Skywalker fanfiction is 'The Chosen One's Redemption'. It delves into Anakin's journey towards redemption after his fall to the dark side. It shows his internal struggles and how he tries to make amends for his past actions. Another is 'Anakin in Exile' which imagines Anakin living in seclusion and reflecting on his life. It gives a deeper look into his character outside of the main Star Wars narrative.
One common plot twist could be Anakin having memories of his previous life right from the start. Instead of slowly realizing his destiny, he is immediately aware of the mistakes he made in his past life as Vader. This could lead to him making different choices much earlier, like not getting involved with Palpatine at all. He might also use his knowledge of the future to prevent certain tragedies, such as the death of his mother in a more direct way than in the original story.
One idea could be a story where Anakin and Ahsoka are reunited after a long time apart. Maybe Anakin has been on a secret mission and Ahsoka has been exploring new parts of the galaxy. When they meet again, they have to work together to face a new threat that is endangering the Jedi Order.
In such a fanfiction, perhaps they could engage in a lightsaber duel to test each other's skills. The female Skywalker might be from an alternate timeline or a previously unknown part of the Skywalker family. They could also exchange stories about their experiences with the Force.
The plot could involve the female Skywalker being a time - traveler who comes to Anakin's era to change his fate. She might try to stop him from turning to the Dark Side by showing him a different future.
Often, it would be depicted as a very emotional moment. Luke might be filled with a mix of awe, anger (for Anakin's past as Vader), and longing for a true father - son bond. Anakin could be shown as a figure full of remorse, reaching out to Luke in a desperate attempt to make amends.
In fanfiction, when Luke meets Anakin, they might have an intense emotional reunion. Luke could finally get the father - son relationship he always desired. Anakin might impart some long - lost Jedi wisdom to Luke,弥补 the time they lost when Anakin was Darth Vader.
