Give it a unique appearance. For example, instead of the typical fire - breathing red dragon, make it a blue - scaled dragon that breathes ice. Also, give it a distinct personality. It could be a shy dragon that is afraid of its own power.
Some common themes include the dragon's quest for a place in a world that fears it. Dragons are often powerful and misunderstood, so they might be on a journey to prove they can co - exist with other beings. Another theme is the dragon - rider bond, which can be a deep and spiritual connection where they fight together and protect one another.
One popular 'Once a upon a time story' is 'Cinderella'. It's about a kind - hearted girl who is mistreated by her stepmother and stepsisters but eventually finds true love with the help of her fairy godmother. Another is 'Snow White', a beautiful princess who has to flee from her evil stepmother and finds refuge with the seven dwarfs. And 'Sleeping Beauty' is also well - known, where a princess is put into a deep sleep by a curse and is awakened by a prince's kiss.
One common theme is power and its corrupting influence. The Dragon Queen is a powerful character, and many fanfictions explore how she deals with power, whether she succumbs to its dark side or uses it for good. For example, some stories might show her struggling to control her dragon - like powers in a new situation.
The relationship between the dragon and the swan queen could be one of friendship. The dragon, being a fierce but lonely creature, finds solace in the company of the swan queen. She, with her kind and empathetic nature, accepts the dragon as it is. They might share stories under the moonlight, with the dragon's tales of far - off lands and the swan queen's stories of the local forest.
The moral could be about the power of courage. In many dragon stories, the hero has to face the fearsome dragon. By showing courage, like the knight in shining armor, they can overcome great challenges. This teaches us that in real life, we should also be brave when facing difficulties.
It could be about the letters exchanged during war within the context of the 'Once Upon a Time' universe. Maybe the fanfic focuses on how these letters affect the relationships between characters, like how a letter from a soldier might change the way a character in the story feels or acts.
A great idea for an Once Upon a Time fanfic is to give a happily - ever - after to a character who didn't get one in the show. Take Neal Cassidy, for instance. You could write a story where he somehow comes back to life and reunites with his son Henry in a more complete way. Or you could do a time - travel fanfic where a character goes back in time to change a crucial event. This could lead to a whole new chain of events and relationships in the Once Upon a Time universe.
A possible plot could be about a lemon that has magical powers. It might live in a world where fruits have their own society. The lemon could go on an adventure to find a special ingredient to save its ill friend in the orchard.
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.
