One common theme could be self - discovery. Henry might be exploring his identity in a world full of magic and different relationships. Another theme could be forbidden love, as in the original 'Once Upon a Time' there are many complex relationship dynamics that could be adapted to a gay relationship involving Henry.
One popular trope is the 'Enemies to Lovers'. For example, a hero and a villain character from 'Once Upon a Time' might start off hating each other but gradually fall in love. Another is the 'Soulmate' trope, where two characters are fated to be together, which adds a touch of magic and destiny to the story. And of course, the 'Hidden Relationship' trope is also common, as characters may have to keep their relationship a secret due to the circumstances in the 'Once Upon a Time' universe.
Family relationships are a big theme. Some fanfics focus on the family dynamics between characters like the Charmings and their descendants. There are also fanfictions that revolve around the theme of identity. Characters in 'Once upon a time' often have complex identities, and fan writers like to dig deeper into how these identities are formed and how they can change over time.
A 'found family' trope is quite common. Characters who were alone or estranged in the show form a close - knit family in fanfiction. For instance, Henry might bring together different characters who then become his new family. Also, the 'hurt/comfort' trope, where a character is hurt (physically or emotionally) and another character comforts them, is frequently used in Once upon a Time fanfics.
Begin by choosing your favorite characters from 'Once upon a time'. Decide if you want to focus on one character's story or a group of them. After that, plan out the plot. You can make a simple outline of the beginning, middle and end. Consider the setting, whether it's the Enchanted Forest or Storybrooke. Also, think about the tone of your fanfic. Do you want it to be light - hearted, dark, or something in between? Once you have these elements in place, just start writing. Don't worry too much about making it perfect at first, you can always edit later.
A prevalent trope is the 'reincarnation' trope. Fans might write about how the characters are reincarnated in different time periods or worlds and how their relationships are rekindled. 'Power - swapping' is another interesting one, where characters exchange their powers and how that affects their relationships and the story. There are also 'secret relationship' tropes, especially for characters who had a lot of chemistry on the show but never got together officially, like Belle and Will Scarlet. Writers create scenarios where they have a secret relationship and all the drama that comes with it.
