Their relationship could be portrayed as more of a friendship at first. They start as comrades in the fight against the Separatists during the Clone Wars, and slowly their feelings develop. This would be a different take from the instant attraction in the movies.
Another way is to show their relationship as a source of strength for Anakin in the Clone Wars. Instead of it being a weakness as some might think, their love gives him the motivation to fight harder and be a better Jedi. He is inspired by Padme's courage and ideals, and this helps him make better decisions on the battlefield.
Their relationship could be portrayed as more of a partnership in the Clone Wars. Instead of just a romantic couple, they could be shown as two people with different skillsets who are equally important in achieving victory. For example, Padme could be more involved in the military strategy discussions with Anakin, using her political knowledge.
Their relationship could be developed differently by having them be more open about their relationship from the start. Instead of hiding it, they could face the consequences together, which would change the whole dynamic with the Jedi Council and the Senate.
One great fanfiction could be about Anakin and Padme's secret meetings during the Clone Wars. Maybe Anakin is on a dangerous mission, and Padme is worried sick. She uses her political influence to try and get information about his safety. This adds a lot of tension and drama to their relationship, which was already filled with so many challenges in the official story.
Well, instead of the somewhat quick development in the movies, in fanfiction it could be a slow - burn relationship. They start as just friends, with Anakin seeing Padme as a role model. Padme, on the other hand, just thinks of Anakin as a sweet boy. As time passes, they gradually realize their deeper feelings through shared experiences like helping the poor on a far - flung planet.
The kiss can be used to contrast with the chaos and conflict in the Star Wars universe. While there are battles and political intrigues going on, their kiss represents a private, emotional sanctuary for Anakin and Padme. Fanfiction might expand on this by showing how this moment gives them strength to face the challenges outside their relationship.
Another way is to show a relationship full of regret. Anakin could be filled with remorse for how he treated Ahsoka in the past, but his dark side self still has the urge to do harm. Ahsoka, on the other hand, is conflicted between her love for the old Anakin and her need to oppose the current, dark Anakin.
Another interesting aspect in such fanfiction is how their relationship affects the overall Star Wars universe. Their love was a catalyst for many events. Fanfiction writers might explore how their relationship could have influenced the political situation in the galaxy. Maybe they could have united different factions through their love, or their union could have been a symbol of hope for a more unified and peaceful galaxy.
I really like the fanfiction 'Anakin and Padme: Unseen Moments'. It focuses on the little - known moments between them during the Clone Wars. It has some really touching scenes, like when Anakin gives Padme a small trinket he made during a lull in the fighting. The author does a great job of portraying their love as something that endures despite the hardships of war.
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.
Another interesting plot could be Padme getting kidnapped during the Clone Wars and Anakin going on a desperate rescue mission. Along the way, he has to face his inner demons and the challenges of the war - like dealing with his Jedi duties and his love for Padme at the same time. This would really test his character and loyalty.
