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 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.
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.
As Padme is pregnant, Anakin may start to think more about his future and his place in the galaxy. This could lead to deeper conversations between them about their values and what they want for their family. Their relationship will grow as they both adjust to the idea of becoming parents and all the responsibilities that come with it. They'll have to support each other through the physical and emotional changes that Padme is going through, and also deal with the external threats to their family.
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.
One plot idea could be Anakin and Padme having to work together secretly during a Clone Wars mission. Maybe they are on a planet where they need to negotiate with a local leader who is sympathetic to the Separatists. Anakin has to use his Jedi skills and Padme her diplomatic skills to turn the situation around.
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.
There are also some Star Wars fan communities on social media platforms. For example, on Reddit, there are subreddits dedicated to Star Wars fanfiction. You can post a request for Anakin, Padme and Clone Wars fanfictions there, and the community might be able to point you in the right direction. Additionally, some Star Wars fan forums may have sections for fanfiction sharing and discussion.
One great fanfiction could be about Anakin and Padme's secret meetings during the Clone Wars. Maybe it focuses on how they struggle to keep their relationship hidden while Anakin is constantly on the front lines. Another could be a story where Padme gets involved in a Clone Wars battle in an unexpected way, with Anakin having to protect her and fight at the same time.
