A third idea could be a love - triangle situation. A new character enters their lives and there's some confusion about feelings. Jack might start to have feelings for this new person, which makes May jealous, and they have to sort out their relationships while still facing the normal challenges in their world.
Another fanfiction idea could be a time - travel aspect. Maybe Jack and May get sent back in time to when their world was first created. They then have to figure out how to get back to their own time while also dealing with the primitive and often dangerous conditions of the past.
Another idea is that Jack and May are given a special task by an ancient being. They have to find a set of magical artifacts scattered across their land. However, there are other forces that also want these artifacts for evil purposes. Jack and May's journey is filled with challenges, and they also have to deal with their own personal growth and relationship development as they complete the task.
One idea could be a crossover where characters from 'half upon a time' meet characters from another well - known fairy - tale world. This could lead to some really unique and humorous interactions as they try to navigate each other's rules and cultures.
Jack and May are the protagonists. In fanfiction, they could be given different personalities and backstories from the original source (if there is one). They might be best friends, siblings, or lovers, depending on how the author of the fanfiction chooses to portray them.
A powerful sorcerer could be the main antagonist. He might be jealous of Jack and May's emerging powers and see them as a threat to his own plans of ruling the land. So, he tries to stop them at every turn, creating various obstacles and sending his minions after them.
One idea could be exploring the backstories of the lost boys in more detail. Maybe one of them has a hidden connection to a character from the outside world. Another plot could involve a new villain coming to Neverland who has a different kind of magic that challenges Peter Pan. Also, a story about Wendy's granddaughter returning to Neverland to find a lost family heirloom could be interesting.
One idea could be exploring Drizella's backstory before she became so bitter. Maybe she had a true love in her youth that was torn away from her, which led to her descent into jealousy and meanness.
Well, you could create a 'once upon a time parody fanfiction' where the magic in the fairytale world is actually just advanced technology that the characters don't understand. For instance, the fairy godmother's wand could be a high - tech device from a more advanced civilization. Also, you could make the villains into bumbling idiots instead of the menacing figures they usually are. This would add a lot of humor to the story.
I'm not entirely sure as it's not a very common or well - known specific 'fanfiction'. It could potentially be a play on 'Once upon a time' but for a series in the form of fan - created fiction. Maybe it's about a unique take on a beloved series, with its own set of characters and plotlines that are inspired by the original series.
One idea could be a story where in the Once Upon a Time universe, a character gets a magical haircut. Maybe the Evil Queen's hair is cut by a mysterious stranger, and with the loss of her long, flowing locks, she loses some of her power. Her vanity was tied to her hair, and now she has to adapt to a new look and a new level of strength.
One idea could be a new agent arriving at Warehouse 13 with a mysterious past that turns out to be linked to an artifact that was thought to be lost forever. This new agent might unknowingly hold the key to controlling the artifact's power, causing a stir among the existing agents as they try to figure out how to handle the situation.
