One great example could be a crossover between 'Once Upon a Time' and 'Harry Potter'. Imagine the fairy - tale characters from 'Once Upon a Time' finding their way into the magical world of Hogwarts. Snow White could be a student in the Defense Against the Dark Arts class, learning spells alongside Harry and his friends. Another example is a crossover with 'The Lord of the Rings'. Characters like Regina might be intrigued by the power of the One Ring and get involved in the epic quest in Middle - earth.
A 'Once Upon a Time' and 'Doctor Who' crossover fanfiction would be really interesting. The Doctor could land in Storybrooke and start meddling with the fairy - tale characters' lives. He might try to solve the mysteries of the Evil Queen's curse using his time - traveling knowledge. Also, a crossover with 'Star Wars' could see characters like Emma Swan using the Force in some way. Maybe she discovers she has some Jedi - like powers that help her fight against the villains in her own world.
I found a really fun crossover fanfic where the villains from Descendants team up with some of the forgotten villains from Once Upon a Time. It's called 'Villainous Alliances'. It shows how they would interact and form plans to take over both their worlds. The character development in this fanfic is quite good as it gives more depth to the Descendants' villains who might seem one - dimensional at first.
One great Teen Wolf and Once Upon a Time crossover fanfiction is 'The Lost Wolf in Storybrooke'. It combines the dark, supernatural elements of Teen Wolf with the fairytale - like world of Once Upon a Time. The story has Scott McCall finding himself mysteriously transported to Storybrooke and having to navigate the new rules and characters there. It's really exciting to see how he interacts with the likes of Emma Swan and Regina Mills.
There is. I've come across some interesting ones. A lot of these fanfictions play with the idea of the different magical systems in Merlin and Once Upon a Time. For example, how Merlin's ancient magic would interact with the magic in the fairy - tale world of Once Upon a Time. They often create unique and exciting plotlines that draw you in. It's really fascinating to see how authors blend the two universes together.
You can try websites like Fanfiction.net or Archive of Our Own (AO3). Fanfiction.net has a large collection of fanfics from various fandoms, including Once upon a Time. Just use their search function and type in 'Once upon a Time'. AO3 is also great as it has a well - organized tagging system, making it easier to find specific types of Once upon a Time fanfiction, like those focused on a particular character or relationship.
Character interactions are key. Imagine Stiles from Teen Wolf and Rumplestiltskin from Once Upon a Time having a conversation. It should be both interesting and in - character. The fanfic should also introduce a new and exciting plot that couldn't exist in either show alone. Maybe a new threat that combines the darkness of the Nogitsune from Teen Wolf and the power - hungry villains from Once Upon a Time. Another important aspect is the setting. How will Beacon Hills and Storybrooke interact? Will there be a merge of the two or just portals between them?
A really good 'Once Upon a Time' fanfiction is 'The Dark One's Daughter'. It has a unique take on Rumpelstiltskin's family. The story is filled with mystery and drama. Another one is 'Hook's Hidden Past' which uncovers more about Captain Hook's life before he became the infamous pirate we know. 'The Fairies' New Magic' is also great as it shows the fairies in a new light, with different magical abilities and a whole new set of challenges they face.
One great 'Black Swan' 'Once Upon a Time' fanfiction is 'The Swan's Transformation'. It delves deep into the character from 'Black Swan' being transported into the 'Once Upon a Time' universe. The story beautifully weaves the dark and complex nature of the Black Swan character into the fairytale - like world of 'Once Upon a Time'. It shows how she adapts to new rules and magic systems while still maintaining her own unique identity.
One great 'Once Upon a Time' body swap fanfiction is 'Swapped Souls in Storybrooke'. It has an interesting take on how different characters would react when they swap bodies. For example, Emma and Regina swapping bodies creates a lot of humorous and also some heart - touching moments as they try to understand each other's lives better. Another one is 'The Enchanted Swap' which delves deep into the relationships between the characters in a whole new light due to the body swap.
One great 'Once Upon a Time Tiger Lily' fanfiction is 'Tiger Lily's Redemption'. It explores her backstory more deeply and her relationship with other characters in the show. Another one to check out is 'Tiger Lily and the Enchanted Forest', which has a really interesting take on her adventures in the forest.
One great 'Wendy Darling Once Upon a Time' fanfiction is 'Wendy's New Adventure'. It takes Wendy into a whole new realm within the Once Upon a Time universe. She teams up with some unexpected characters and has to face a new dark threat. The author does a wonderful job of keeping Wendy's character true to the original while also adding new layers to her personality.
