A unique plot could involve a CW character who is a detective trying to solve the mystery of the Beast's curse as if it were a crime. They could interview the servants, gather clues around the enchanted castle, and try to piece together what really happened to the Beast.
One idea could be that the characters from the CW shows end up in the Beauty and the Beast world. For example, a group of CW superheroes might get transported there and have to navigate the magical and dangerous world while also trying to find a way back home. Another idea is that the Beast could be a character from a CW show who is cursed in a similar way and the Beauty character has to come from another CW show to break the curse. It could also be interesting if the two worlds merge and characters from both have to learn to co - exist and deal with the cultural differences between the CW universe and the Beauty and the Beast universe.
To create an engaging Beauty and the Beast Star Wars fanfiction, focus on the characters. Take a character from Star Wars, like Rey, and put her in a Beauty and the Beast - like situation. Maybe she crash - lands on a planet where she has to deal with a powerful, beast - like alien. The key is to keep the essence of both stories. The Star Wars elements like lightsabers and the Force can add an exciting twist to the traditional Beauty and the Beast plot. You could also have a droid be the 'beauty' and a malfunctioning, hulking war machine be the 'beast', and they form an unlikely bond.
Fanfic writers can create a unique alternate ending by changing the catalyst for the spell to be broken. Instead of love, it could be something like a great sacrifice. For instance, the Beast sacrifices his last chance at becoming human to save Belle from a greater danger. This would add a new layer of depth to the story. Another way is to change the aftermath. Maybe they don't live happily ever after in the castle, but they build a new home in the forest where they can be closer to nature and away from the trappings of royalty.
First, you could combine the settings. For example, place Naruto in the world of Beauty and the Beast. Maybe Naruto is the one who gets cursed into a beast - like form, with his chakra being affected in a strange way. His friends in Konoha could be the ones who try to break the curse, similar to how Belle tries to understand and help the Beast in the original story. You can also include some of the Naruto elements like jutsus into the story. For instance, Naruto could use his Rasengan to protect the 'castle' (which could be a transformed place in the Naruto world) from enemies.
A unique plot could involve the T - 3000 being reprogrammed by an unexpected force from the other crossover universe. This new programming could give it a whole new set of goals and morals, which would completely change its role in the story.
Combine different magic systems. For example, if crossing with the Magicians world, mix the Hogwarts magic with Brakebills' magic. The champions could struggle to adapt to new spells and incantations. Another way is to change the nature of the tasks. Instead of the usual tasks, make them more like a detective mystery where the champions have to solve a magical crime to progress in the tournament.
Mix the cultures. For example, if crossing with the Game of Thrones universe, combine the complex politics of Westeros with the four - nation system of the Avatar world. Maybe there's a power struggle over the Iron Throne, but the benders have their own influence due to their powers. Another way is to create a new threat that can only be defeated by the combined powers and knowledge of both universes.
Well, you could start by thinking about the two universes you want to cross. For example, if it's Percy Jackson and Star Wars. Maybe Percy gets transported to the Star Wars universe. He could use his powers in unique ways, like using water manipulation to deal with the desert planets. His demigod abilities would be seen as a strange and new force in that galaxy.
For a more unique plot, consider that the Stranger Things characters are transported to an alternate Hawkins that is completely obsessed with Halloween all year round. The Upside Down has seeped into this version of Hawkins in a different way, and it's all mixed up with the town's extreme Halloween culture. They have to find a way back to their own Hawkins while also uncovering the secrets of this strange, Halloween - infused Upside Down. This could involve meeting alternate versions of themselves and other spooky elements specific to this world.
You can start by thinking about the worlds of the two shows or franchises you want to cross. For example, if crossing with Ben 10, you could have the Beetleborgs' dimension start to merge with Ben's. The Beetleborgs would have to figure out how to stop it while also dealing with the aliens that Ben 10 usually battles. This creates a unique situation where they have to adapt to new enemies and environments.
