To write a fanfic focusing on their friendship, start with a simple moment like them sharing a meal together and reminiscing about their adventures. You can then add some conflict, maybe Flynn has to go on a dangerous mission alone but Rapunzel doesn't want him to go. Show how they communicate and work through their differences. For example, Rapunzel might use her charm and wisdom to convince Flynn to let her come along or at least to be more careful. They could also have inside jokes that you sprinkle throughout the story to show the depth of their bond.
Flynn in fanfic is often shown as intelligent. He uses his wits to get out of tricky situations. In a fanfic about a mystery in the castle, Flynn figures out the clues and solves the mystery before anyone else, showing his sharp mind.
One common theme is adventure. Flynn is often depicted going on new and exciting adventures. Another is love, especially his relationship with Rapunzel. And his past and how it shaped him is also a popular theme.
A fanfiction could explore a backstory where Flynn Rider and the Stabbington Brothers were once friends or at least allies. They could have had some sort of falling out over a big heist gone wrong. The story could then focus on how they might overcome their differences and work together again. For example, Flynn discovers that the Stabbington Brothers were set up in the previous heist and he decides to help them clear their names.
The Tangled the Series builds on the foundation of the movie. It deepens the relationships, introduces new plotlines, and keeps the charm of the original. There are callbacks to familiar elements, but also fresh surprises.
There are fan fictions where Flynn Rider gets transported to a different realm. In this new world, he has to use his charm and thieving skills in unexpected ways to survive and find a way back to his own world. It often involves him making new allies and facing new foes.
