Yes, there are many. Some fanfictions focus on their relationship in a platonic or alternate - universe way where a kiss might be a sign of deep affection within the context of their family - like bond or a moment of extreme emotion in a non - romantic sense.
Well, in some fanfictions, the kiss might be a dream sequence. It could represent Leia's subconscious thoughts about Luke as a protector or a very important person in her life. It doesn't have to be romantic, but rather a symbol of their intertwined destinies. And then there are those fanfictions where the kiss is a way to break a curse or a dark spell that has been cast upon them, showing their combined power.
Perhaps a fan fiction where Luke and Leia travel back in time to the days before the Clone Wars. They could use their knowledge of the future to try and prevent the events that led to the rise of the Empire, all while trying to keep their identities a secret.
Yes, there are many great ones. You can find them on various fanfiction websites. Some explore their relationship in alternate universes, like a universe where they face different threats together and their bond deepens in unique ways.
Imagine a plot twist where Luke turns to the dark side, and it's up to Leia to bring him back. This would be a complete reversal of their expected roles and would add a lot of drama and tension to the fan fiction. It could also explore the idea of how strong Leia's love for her brother really is and what she's willing to do to save him.
Another option is Wattpad. Although it has a wide variety of content, you can find some interesting Luke Skywalker x Princess Leia fanfiction there. However, the quality may vary, so you might need to do some sifting through the stories.
Perhaps they have to team up to convince a group of war - torn planets to join the Rebel Alliance. They use their unique abilities, Luke's connection to the Force and Leia's diplomatic skills, to sway the planets. Along the way, they also learn more about their family's history and how it can help in their mission.
Their relationship can be explored by showing their training sessions together. Since Luke is more trained in the Force, he could teach Leia some advanced techniques, and in the process, they could have deep conversations about their future roles in the galaxy.
Leia and Luke could find themselves in a situation where they have to deal with a new Sith Lord. This Sith Lord has a unique power that they have never encountered before. They would have to quickly figure out how to counter it, perhaps by combining their own powers in an unexpected way.
One possible fanfiction could be about Leia and Luke going on a secret mission together. Maybe they are trying to uncover an ancient Sith artifact that could potentially destroy the galaxy if it falls into the wrong hands. They would use their unique Force abilities, Leia's diplomatic skills and Luke's Jedi training to outwit their enemies.
