Another interesting plot could be set in an alternate universe where Padme survives. She then devotes her life to raising Luke and Leia, teaching them about their father's true nature before his fall. This could lead to a story of redemption for Anakin through his children, as they strive to bring him back from the Dark Side.
One great storyline could be a 'what if' scenario where Anakin doesn't turn to the Dark Side. In this, he and Padme raise Luke and Leia together. The twins grow up with their father's Jedi training and the family lives in harmony, facing the challenges of the galaxy as a united front.
A more adventurous storyline might involve Luke and Leia discovering a hidden journal of Padme's that reveals secrets about their father and the Force. They then embark on a journey across the galaxy, using the knowledge in the journal to uncover more about their family history and their own destinies in the Force.
Here's another idea. Suppose there's a threat to the galaxy that can only be stopped by using a long - lost technique that Padme knew about. Luke and Leia, with the help of Anakin's spirit, embark on a quest to find out about this technique. They face many challenges, including political intrigue and dark side threats, all while coming to terms with their family's complex history.
I really liked 'The Time - Traveling Skywalkers'. It's a story where all four characters are caught in a time - travel anomaly. They end up in different points in time relative to each other. Padme gets to see a future where her children have grown up strong despite all the hardships. Anakin has to face his past self and tries to guide him away from the dark side. Luke and Leia use their knowledge of the future to try and make the galaxy a better place in the past. It's a really engaging read.
Some fanfics take a different approach to Anakin's fall. Instead of it being a complete turn to the dark side, he may be in a more grey area. And Padme is often written as the one who could have pulled him back completely. Luke and Leia in these stories might be more proactive in trying to understand their father's true nature and not just seeing him as the evil Vader. For instance, there's a fanfic where Luke goes on a journey to find out more about Anakin's past before he became Vader, and Leia joins him later. This gives a whole new dimension to their family dynamic.
One idea could be a time - travel plot where Luke and Leia are sent back in time and meet their parents, Anakin and Padme, before Anakin's fall to the dark side. They try to prevent the events that led to the rise of the Empire.
There are some fanfictions where the time travel is not just about changing the past, but also about learning from it. For instance, Luke travels back to the time of his father's youth. Instead of trying to directly change Anakin's path, he tries to understand the root causes of his fall. He then takes this knowledge back to his own time to better prepare the Jedi order for future threats. And Leia, when she travels back, might focus on building alliances that could have prevented the rise of the Sith in the first place. This kind of plot adds depth to the characters and the overall Star Wars universe.
Perhaps it's a time - travel scenario in the fanfiction. Luke and Leia, having discovered a way to travel back in time, meet their parents. Anakin would be shocked to see his grown - up children, and Padme would be in awe of the strong Jedi and princess they have become. They could exchange stories of their lives, with Luke and Leia learning about their parents' early days.
Perhaps a fanfic that delves into the time when Anakin was on the cusp of turning to the dark side. Padme could sense the change in him and tries to prevent it with the help of Luke and Leia from the future who somehow travel back in time. This would create a complex web of relationships and a race against time to save Anakin from the dark side.
One idea could be a story that focuses on Anakin's internal struggle between his love for Padme and his fall to the dark side as Darth Vader, while Luke and Leia unknowingly grow up in the shadow of their father's actions. It could explore how their lives might have been different if Anakin had not turned, and how they eventually come to terms with his true identity.
A possible plot is a fanfic where Anakin, in his Darth Vader form, has a vision of a different future where he didn't lose Padme. This vision makes him question his loyalty to the dark side. Meanwhile, Luke and Leia are on a mission to rescue their father from the clutches of the Emperor. The story could be filled with emotional reunions and battles between the light and dark forces.
The idea of redemption is a big one. Darth Vader's redemption at the end of Return of the Jedi is a powerful moment, and fanfics often expand on this. They might explore what led to his final choice, or how his family influenced his decision. Additionally, the exploration of the Force and how it connects all these characters is another common theme. It could be about how Luke and Leia develop their Force abilities differently, or how Anakin's relationship with the Force changed over time.
