One idea could be that the Beast has a secret power that he's been hiding from Belle. Maybe he can communicate with the forest animals in a unique way and they help him in his quest to win Belle's true love. Another could be a backstory for the Enchantress who cursed the Beast, showing her reasons and her own journey. Or perhaps Belle discovers a hidden library in the castle that contains the secrets of breaking the curse not just for the Beast but for the entire enchanted castle and its inhabitants.
Well, here's a plot idea. There could be a rival for Belle's affection in the form of a handsome but devious nobleman from a neighboring kingdom. He tries to win Belle over and convince her that the Beast is truly a monster. Meanwhile, the Beast is trying to prove his worthiness not just to Belle but also to the people of his own kingdom who are also affected by the curse. And perhaps there are magical artifacts in the castle that play a crucial role in either breaking or strengthening the curse depending on how they are used.
A plot idea could be that Belle has a twin sister who was also kidnapped by the Beast. But this sister is very different from Belle, she's more headstrong and less patient. Their different reactions to the Beast and the situation in the castle create a lot of chaos and also new ways of looking at the curse. Also, what if the Beast's appearance changes gradually as he and Belle grow closer in an unexpected way, not just the final transformation into a prince.
Well, a great plot might be that a new character enters the Fairy Tail world who is already under a Beauty and the Beast - like curse. The Fairy Tail members don't initially trust this beast - like person but as time goes on, they discover his good heart. Maybe he has some special power that could help the guild in a future battle, and in the process of working together, the curse is broken.
A great plot twist is when the objects in the castle, instead of just being there to serve as comical relief or side characters, are actually the ones who put the curse on the Beast in the first place, out of some misdirected sense of loyalty or protection. Also, Beauty could turn out to be a long - lost princess from a neighboring kingdom, and her union with the Beast has political implications that add a whole new layer to the story.
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.
An interesting new character could be a half - human, half - fae being. This character could have been trapped in the castle long before Belle arrived. He has knowledge of ancient spells and magic that could potentially help in breaking the curse. Another character could be a friendly giant who lives in the mountains near the castle. He is feared by the local villagers but is actually a gentle soul. He might play a role in protecting the castle from outside threats or helping Belle in her journey to understand the Beast better.
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.
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.
Well, a cool fanfiction concept could be that Belle discovers a hidden part of the castle that holds the secrets of Beast's past. As she uncovers these secrets, it deepens their relationship even more. Or perhaps a story where Beast gets turned human for a short time and he has to adapt to the human world without Belle by his side at first. He then realizes how much he truly depends on her. Another interesting one would be a fanfiction where Belle's father gets lost in the enchanted forest again, and Beast and Belle have to go on a new adventure to find him.
One idea could be that Draco is cursed to be a beast and Hermione stumbles upon his enchanted lair while on a research mission. She initially fears him but then realizes there's more to him than his beastly exterior.
One idea could be a 'what if' scenario where Gaston has a change of heart. Maybe he realizes Belle's kindness towards the Beast makes her truly special and he tries to make amends for his past behavior. He could start by helping the villagers understand the Beast better instead of leading them to attack the castle.
