What are some interesting plot ideas for a 'Beauty and the Beast' sister fanfic?

One idea could be exploring the Beast's past more in - depth. Maybe show his life before the curse and how it affected his personality. Another could be a modern - day retelling where Belle is a scientist trying to find a cure for the Beast's curse.

One idea could be that Belle discovers she's pregnant shortly after the curse on the castle is fully broken. This could bring a new sense of joy and anticipation to the castle. The Beast, now a prince again, might be both excited and a bit nervous about becoming a father. He could start making preparations like renovating a special nursery in the castle. Another idea is that during Belle's pregnancy, some of the enchanted objects in the castle could take on new roles as babysitters or helpers, adding a touch of magic to the pregnancy journey.

In a genderbend fanfic, the female Beast could be a sorceress who was betrayed and cursed. The male Beauty could be a traveling minstrel. His music has the power to soothe her and as he stays in her enchanted castle, they start to understand each other. The Beast begins to let down her guard and the Beauty discovers her true self beneath the curse.

One idea could be that the little sister has a special gift that helps break the curse in a different way. For example, she might be able to communicate with the enchanted objects in a more profound way and they guide her to find a solution. Another idea is that she gets lost in the forest on her own adventure and stumbles upon the Beast's castle before her sister does. She could form an unlikely friendship with some of the castle's inhabitants which then sets the stage for when her sister arrives.

One idea could be exploring the Beast's past more deeply. Maybe a story about his life before the curse, his relationship with his family and how it all led to his current situation.

One idea could be that Belle discovers a hidden garden in the Beast's castle that has magical plants which can talk and offer her advice. Another could be a backstory for the Beast, like how he got cursed in a more detailed and different way than in the original story. For example, he was tricked by a jealous wizard who wanted the castle for himself.

A great idea for a 'Beauty and the Beast II' fanfic is to focus on the side characters. For example, Lumière and Cogsworth. You could write a story from their perspective, perhaps about their efforts to keep the castle running smoothly during Belle and the Beast's courtship. Or you could create a new character, like a lost traveler who stumbles upon the castle and has a unique reaction to the Beast and his servants. This new character could bring in new plot twists, like having a special power or knowledge that could either help or hinder the Beast and Belle's relationship.

A great fanfic idea is that in a post - happily - ever - after world for Cinderella, she hears about the Beast's plight. She decides to use her new - found status as a princess to help him. Maybe she brings some of her own magic items, like her glass slippers, to try and break the curse. Another could be that the Beast, while still in his cursed form, stumbles upon Cinderella's village. He is initially feared, but Cinderella sees past his exterior and offers him shelter. This starts a friendship that could develop into something more as the story progresses. And a different approach could be a fanfic where the story is told from the perspective of the servants in the Beast's castle as they watch Cinderella and the Beast fall in love.

A great plot idea could be to introduce a new character, perhaps a wizard who is trying to either break the curse in a different way or make it worse. This new character could bring a whole new level of conflict and mystery to the story. Also, you could write about Belle and the Beast traveling to different magical lands together, facing new challenges and learning more about each other along the way.

Maybe the Dark Beauty is not truly human but a being from another dimension. She and the Beast have a connection that transcends their different forms. They must figure out how to break the curse on the Beast's castle while also dealing with her other - dimensional nature.
