For Anakin, you need to show his internal struggle. Remember his fall to the dark side was due to his fear of loss. So, in fanfiction, show his conflicted nature. For Padme, write about her strong will and her love for Anakin and the galaxy. Luke should be shown as an idealist, always believing in the good in people. And for Leia, emphasize her leadership skills and her fiery spirit.
When writing Anakin, think about his relationship with Obi - Wan. This can add depth to his character. Padme's relationship with her family and her home planet can also be explored to make her more believable. Luke's naivete at the start and his growth into a Jedi should be a key part of his character. For Leia, her interactions with the Rebel Alliance members and how she earns their respect can make her character more real. You also need to consider their dialogue. Anakin might have a more intense and sometimes brooding way of speaking. Padme would be more diplomatic and poised. Luke would be enthusiastic yet a bit inexperienced in his speech at first, and Leia would be assertive and commanding.
To write a believable Anakin, explore his past as a slave and how that shaped his view of power. Padme can be believable by showing her diplomatic side and her ability to make tough decisions. For Luke, his journey in learning the Force should be detailed, from his initial disbelief to his mastery. Leia's character can be made believable by showing how she balances her political duties with her new - found Force abilities.
You could also explore their relationships in a post - apocalyptic Star Wars setting. Suppose there has been a great war that has changed the galaxy. Luke, Leia, Anakin (if redeemed) and Padme (if alive) have to come together and rebuild their family while also trying to restore order to the galaxy. Their relationships would be tested and strengthened in this new and difficult situation.
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.
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.
In a time - travel scenario, Anakin and Luke's relationship could be transformed. Luke could finally understand his father's struggles more intimately by being present in the past. Padme and Leia might form a stronger bond as well, with Padme being able to mentor Leia in ways she couldn't before. Their relationships would be shaped by the new shared experiences in different time periods and the knowledge they gain from those travels.
The fanfic could be set during the Clone Wars. Anakin's dark side starts to emerge due to the stress and manipulation. Padme notices the changes in him. Meanwhile, Luke and Leia are prophesied to be the ones who can save the galaxy from the dark side that Anakin is falling into. It could show how their fates are intertwined even before they are born, with Padme trying to protect the future of her children and Anakin.
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.
Often, Anakin and Padme's love in fanfic is intensified. It might show Anakin's internal struggle with the dark side while still being deeply in love with Padme. Luke's love in fanfic could be about his love for the galaxy, his friends, and his family, which might also translate into a romantic love for someone special. Leia's love could be about her strong love for her people and her planet, and this could be intertwined with her romantic love for Han Solo or other potential love interests in fanfic.
There is a fanfic called 'Padme's Hope'. In this, Padme survives and plays a crucial role in bringing Anakin back from the dark side. It also has great character development for Luke and Leia as they grow up with both their parents. It's a very heart - warming take on the story.
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.
