What are some interesting plot ideas for a 'beauty and gasser fanfic'?

The 'beauty' could be a young woman named Lily. She is kind - hearted, brave, and has a great sense of curiosity. The 'gasser' could be a strange creature named Zog. Zog has the ability to emit a special gas that can either heal or harm, depending on how it's used. Lily stumbles upon Zog in the forest and their story begins.

One idea could be that the Beast has a secret power that he reveals to Beauty during a dangerous situation. For example, he can control the elements to protect their castle from an invading force. Another plot could involve Beauty having a hidden past where she was once a princess from a far - off land and her family is searching for her. Or perhaps there could be a new character introduced, like a mischievous fairy who tries to create chaos between Beauty and the Beast by causing misunderstandings.

One idea could be that the Queen of Love and Beauty has to prove her worthiness to keep her title. Maybe there are challenges set by the gods that she must overcome, like taming a wild magical beast. Another could be a love triangle where she is caught between a noble knight and a mysterious wizard, both vying for her heart. And perhaps she has to use her powers of love and beauty to heal a broken land that has been ravaged by war.

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.

One idea could be that the sister of Beauty is a healer. She secretly tries to find a cure for the Beast's curse while also getting to know him in a different way than Beauty does. This could add a new layer of relationship and mystery to the story.

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 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.

Perhaps Beauty discovers a hidden room in the castle that holds the past memories of the Beast in human form. This could lead to a deeper understanding between them and a new twist in their relationship. There could be old portraits, diaries, etc., that show his true self before the curse.

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.
