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.
Some great fanfiction ideas for Belle and Beast are as follows. There could be a story where Belle starts a library in the castle and invites neighboring villages to come and read. Beast is initially hesitant but then sees how it brings joy to everyone. Another is a fanfiction where Belle has a nightmare about losing Beast, and it makes them both realize how precious their relationship is. And a really unique idea could be a story where Beast can transform into different animals at will, and Belle has to help him control this new power while also dealing with the reactions of the castle's inhabitants.
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.
One interesting plot might be that Gaston somehow gets transported into the enchanted castle with Belle. He then has to learn to live with the enchanted objects and the Beast. This could lead to humorous situations as Gaston tries to assert his dominance in a place where his usual tactics don't work. At the same time, Belle could see a different side of Gaston as he struggles to adapt, and it could change her perception of him too.
One idea could be Belle exploring the castle gardens barefoot and discovers a hidden part of the garden that has magical plants. Another could be Belle having a barefoot dance with the Beast in a moonlit ballroom. Or perhaps she goes on a barefoot adventure outside the castle and meets some friendly forest creatures who help her understand the Beast better.
A possible plot is that the tavern Belle works in is frequented by hunters who often talk about the Beast. Belle, being the curious and intelligent girl she is, starts to question their motives and the truth behind their tales. Meanwhile, the Beast, in his loneliness, sends his servants in disguise to the tavern to observe Belle. As the story progresses, Belle might get into trouble with the hunters when she defends the Beast, and the Beast has to come to her rescue, starting their relationship in a more action - packed way.
An interesting OC for a Beauty and the Beast fanfiction could be a talking animal servant in the castle who has their own unique perspective on the curse. They could befriend the Beast in a way that no human has before and help him see things from a different angle. Or perhaps an OC who is a forest spirit that is drawn to the magic of the castle. This spirit could interact with both Belle and the Beast, guiding them towards true love. A third idea is an OC who is a young inventor like Belle's father. This character could bring new inventions to the castle that either help or hinder the situation with the curse.
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 the characters from Glee perform a musical version of Beauty and the Beast within the Glee club setting. They could assign roles like Rachel as Belle and Finn as the Beast. Another could be a crossover where the Beast from the fairy tale somehow ends up in the Glee universe and has to learn about music and friendship from the Glee kids. And a third idea might be that the Glee club does a fundraiser by putting on a modern - day retelling of Beauty and the Beast, with unique twists on the characters and their relationships.
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.
One idea could be that Belle's transformation into a beast is a result of a curse placed on her by an envious witch. As a beast, she has to learn to control her newfound strength and anger. Another plot could involve Belle finding other cursed creatures in the forest and forming a sort of 'beast community' where they all support each other in trying to break their curses. Maybe Belle's journey as a beast also makes her understand the Beast from the original story on a deeper level, and she uses that knowledge to find a way to reverse the curse not just for herself but for all the cursed beings.
One idea could be exploring the backstory of the beast in more detail. Maybe he had a different life before the curse and his past relationships or adventures could add depth to the fanfiction. Another plot could involve the belle teaching the beast about a new culture or skill she has, like a unique form of art or a different language.
