A more complex storyline could involve Anakin and Padme trying to broker peace between two warring planets in the Clone Wars. They face opposition from both sides, including some within the Republic who don't want peace for their own greedy reasons. It would show their struggle to do what's right in a time of chaos and war.
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.
A popular fanfiction idea is Anakin and Padme getting married in a more elaborate and secret ceremony. They invite a few close friends like Obi - Wan (who has mixed feelings but respects their love). This storyline could explore their domestic life and how they try to keep their relationship hidden from the Jedi Council.
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.
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.
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.
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 storyline could be about a clone who discovers a hidden power within himself that is somehow related to Anakin. Maybe he starts having visions similar to Anakin's premonitions of the future. This could lead to him trying to find Anakin to figure out what's going on and how they might be connected in a way that was previously unknown.
One popular storyline is Anakin's relationship with his Padawan, Ahsoka Tano. Fanfictions often explore their adventures during the Clone Wars, like facing a new and powerful Sith threat together. Another is Anakin's inner struggle with the dark side. Writers might depict his temptations and how he tries to resist them in different situations. Some fanfictions also focus on Anakin's friendships with other Jedi, like Obi - Wan Kenobi, and how they support or conflict with each other during the chaotic times of the Clone Wars.
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 great storyline could be a 'what if' scenario where Anakin doesn't turn to the Dark Side. In this, he and Padme raise Luke and Leia together. The twins grow up with their father's Jedi training and the family lives in harmony, facing the challenges of the galaxy as a united front.
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.
