Another theme could be their emotional bond without the sexual aspect. How they supported each other through difficult times, like Anakin's struggles with his Jedi training and Padme's role in the Senate. Their relationship was about more than just physical attraction, and fanfiction could delve deeper into their emotional connection and how it affected their decisions in the story.
Another theme is 'what - if' scenarios. Such as what if Anakin didn't turn to the Dark Side? How would their relationship have developed? This allows for a lot of creative storytelling.
One popular theme is the challenges they face as a couple expecting a child in a time of political unrest. Their relationship is already complex, and the pregnancy adds another layer of drama. For example, they might worry about the safety of their unborn child given the turmoil in the galaxy. Another theme could be how they prepare for the baby's arrival, like finding a safe place to raise the child away from the prying eyes of the Jedi Council or the Sith. It could also explore their hopes and dreams for their family's future.
One common theme is the struggle between love and duty. Anakin has his Jedi duties and Padme has her political responsibilities, and their love often conflicts with these. For example, they have to keep their relationship a secret which adds a lot of tension.
The theme of sacrifice also pops up often. Padme is often put in situations where she has to sacrifice her own happiness or safety for Anakin or for the greater good of the galaxy. And Anakin too may have to sacrifice his power or desires to be with Padme in a more positive way.
Guilt is a big theme as well. After hurting Padme, Anakin would likely be consumed by guilt, which could drive his character development in different directions. This guilt can also be a catalyst for him to either fully embrace the Dark Side or try to find a way back to the Light, depending on the direction of the fanfiction.
In some fanfiction set in a more peaceful time, they might interact with a lot of tender moments. They could have picnics and long walks, just enjoying each other's company and having deep conversations about their future.
There might be a fanfiction that delves into an alternate universe where Anakin doesn't turn to the Dark Side. In this story, Anakin and Padme could work together to bring peace to the galaxy in a more diplomatic way. They would use their influence and love for each other to unite different planets and species, facing challenges like political intrigue and cultural differences.
One good storyline could be exploring their relationship before Anakin's fall to the Dark Side. Maybe Padme and Anakin go on a secret mission together, away from the prying eyes of the Jedi Council and the Senate. They face various challenges that test their love and loyalty to each other and the Republic.
One interesting Anakin - Padmé fanfiction could be about their secret meetings on Naboo. In this story, they might share their hopes and fears for the future of the galaxy while surrounded by the beautiful landscapes of Padmé's homeworld.
Obi - Wan Kenobi would be one. He's Anakin's master, and in the fanfiction, he might suspect something about their relationship and have to decide whether to support them or uphold the Jedi Code.
