A possible plot could be that Young Anakin and Padme are caught in the middle of a political conspiracy on Coruscant. They have to work together to expose the truth and clear their names. Along the way, their relationship deepens as they rely on each other's skills. Anakin uses his piloting and Force abilities, while Padme uses her diplomatic skills. It could also show how they deal with the challenges of being from different worlds and having different roles in the galaxy.
Perhaps a fanfiction where Young Anakin and Padme go on a mission to help a small, oppressed planet. They face many difficulties, like fighting against a corrupt local government and a powerful criminal syndicate. This would test their relationship and their individual beliefs. Anakin might be more inclined to use his lightsaber and the Force to solve problems, while Padme would try to find diplomatic solutions. Through this journey, they grow closer and their love becomes even stronger.
One idea could be their first secret meeting on Naboo. Young Anakin is still a bit naive but full of passion, and Padme is intrigued by his unique charm. They could explore the beautiful landscapes of Naboo together while sharing their dreams and fears.
Anakin and Padme could go on a secret mission together during the Clone Wars. They'd have to hide their relationship while facing all kinds of dangerous enemies and situations. It would be exciting to see how they use their respective skills, Anakin's Jedi powers and Padme's political acumen, to get out of trouble.
One interesting plot point could be the reactions of their friends and allies. Obi - Wan, for instance, might suspect something but choose to keep it to himself. Another is how the Sith might try to use Padme's pregnancy as a way to manipulate Anakin further. They could plant false rumors or try to target Padme to get to Anakin.
Well, a plot could revolve around Padme's pregnancy being used as a symbol of hope in the galaxy. The fanfiction could show different factions either trying to protect her or use her situation for their own gain. Also, it could be interesting to see how Padme's friends, like Bail Organa, support her during this time. They could help her find a safe place to give birth and plan for the future of the child in a galaxy full of danger.
A really interesting plot might be about how they deal with Anakin's premonitions of losing Padme. In the fanfiction, they could work together to try and change the future he foresees, perhaps seeking out ancient Jedi or Sith knowledge to find a way.
Perhaps a fanfiction where Anakin, as a Sith, is sent on a mission by Palpatine. But on this mission, he meets a young Force - sensitive who reminds him of his own past. This makes him start to have doubts about the Sith ways. He begins to secretly teach the young one about the Force in a more balanced way, all while trying to hide it from Palpatine.
One idea could be that Anakin's spirit somehow guides Rey in her Jedi training. Maybe he appears to her in visions and imparts his unique knowledge of the Force, especially the more unorthodox aspects he learned during his time. Another plot could involve Rey finding an ancient artifact that was once connected to Anakin, and through it, she uncovers secrets about his past that help her in her fight against the new Sith threat.
A great plot could be that after getting married, they have to deal with the political ramifications. Since Padme is a senator and Anakin is a Jedi, their union might cause unrest in the Republic. Also, their marriage could be a catalyst for Anakin's further exploration of the Dark Side as he tries to protect his new family in ways that the Jedi Code doesn't allow.
One plot idea could be exploring their first unspoken connection. Maybe in the fanfiction, Anakin saves Padme from a hidden threat in the busy streets of Theed. Their eyes meet, and there's an instant spark, a moment that hints at the deeper relationship to come. This would add more depth to their initial encounter, which was somewhat brief in the movie.
There are fanfics that focus on an alternate universe where Anakin doesn't turn to the Dark Side. In this scenario, he and Padme could have a long and happy life together, raising their children in peace. They might travel the galaxy, helping the Jedi Order in different ways and making the galaxy a better place.
