Often, their interactions start from a place of conflict. Anakin's past actions as Vader create a barrier. However, as the story progresses, they may start to understand each other more. For example, Anakin could reveal his true self to Leia, the self that was once a good Jedi. This could lead to moments of deep connection and mutual respect between them. They might also have to work together against a common enemy, which would force them to communicate and cooperate, leading to a more developed relationship.
In many Star Wars fanfics, the relationship between Leia, Anakin, and the concept of a 'ghost' can be really interesting. Leia is Anakin's daughter, and in some fanfics, Anakin's ghost might play a role in guiding or protecting her. For example, he could appear to her at a crucial moment, sharing some wisdom from the Force that helps her make a difficult decision. This could add a new layer of depth to their family connection that wasn't fully explored in the movies.
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 plot idea could be a story where Anakin somehow survives and has a chance to redeem himself through his relationship with Leia. Maybe he secretly protects her without her knowing it's him at first, and as she discovers the truth, she has to grapple with her feelings towards the man who was once Darth Vader. Another idea is a time - travel plot where Leia goes back in time and meets a younger Anakin. She tries to change his path to the dark side, which creates a whole series of complex interactions and consequences.
To write their character dynamics well, first understand their backgrounds. Anakin has his fall to the dark side and his complex past as a Jedi. Leia is a strong - willed Rebel leader. Show the contrast between Anakin's once - noble self and his dark deeds, and how Leia, who is so committed to the light side, reacts to that. For example, if Anakin tries to help Leia in some way, she might be initially suspicious because of his past.
One common theme is redemption. Anakin, having made many mistakes in his life, sees taking care of Leia as a way to atone. It gives him a chance to do good and protect an innocent life.
One possible fanfic could be about Anakin using time travel to prevent the fall of the Jedi Order and save Padame. He could then ensure a better future for Luke and Leia, guiding them in the ways of the Force without the dark shadow of the Empire looming over them.
There are fanfics where the ghost of Anakin is a catalyst for Leia's growth. Leia, who has always been strong - willed and independent, is faced with the presence of her father's ghost. At first, she might be angry or confused. But as she interacts with the ghost, she starts to understand the power of forgiveness and redemption. Anakin's ghost can represent the cycle of life, death, and rebirth in the Force. His presence can help Leia see that there's more to the Force than just the light and dark sides, and this new understanding can transform her in many ways.
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.
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.
