In a Batman and Beauty and the Beast fanfiction, the city of Gotham could be the enchanted castle. Batman, with his secrets and his 'monstrous' vigilantism, is the Beast. The Beauty could be a young artist who is inspired by the city's dark beauty. She gets caught up in Batman's world and through her art and her positive outlook, she starts to change Batman for the better, making him more open and less of a lone wolf.
One way to blend Batman and Beauty and the Beast fanfiction could be to set the story in Gotham. Batman could be the 'Beast' in a sense, isolated in his dark cave - the Batcave. A new character, like a female journalist, could be the 'Beauty' who stumbles upon his world. She might initially be afraid but then start to see the good in him, much like in the original Beauty and the Beast story.
The idea of the outsider is present in both. Belle was an outsider in her village, and Harry was an outsider in the wizarding world at first. In a fanfiction, a new character could be introduced who is an outsider in both the Beauty and the Beast world and the Harry Potter world. This character could be the link between the two stories, trying to find their place and in the process, bringing the two worlds closer together.
In fanfiction, their worlds can also be blended. For example, imagine the Batcave in the Hidden Leaf Village. The advanced technology of Batman's cave combined with the ninja - like secrecy of the village would create a really interesting setting for the story. And the characters would have to interact within this new, merged environment.
A plot could be that Batman is cursed by a new villain in Gotham who has magic powers. This curse makes him look more menacing and animal - like. A girl, who is an expert in ancient magic, comes to Gotham to study. She meets Batman and decides to help him break the curse. As they work together, they fall in love.
One way to blend the Batman and Pokemon universes in fanfiction could be by having Batman encounter Pokemon in Gotham. Maybe some villain has found a way to bring Pokemon into his world and is using them for evil deeds. Batman would then have to figure out the nature of these strange creatures while also dealing with the chaos they cause.
Well, in some fanfictions, it might involve a magical or fantastical element that enables the impregnation in a unique way specific to that story's plot.
Often, the Beast courts Belle in fanfiction by sharing his vulnerabilities and slowly opening up to her. This could involve heartfelt conversations or special gifts to win her heart.
In some fanfictions, it might be depicted as a passionate and romantic connection that develops gradually over time.
To adapt it, you could start with a character from Glee having a dream or a vision of the Beauty and the Beast world. Let's say Santana has this vision. She then decides to bring it to the Glee club. They start to incorporate the story into their own lives and relationships. The characters could take on the personalities of the Beauty and the Beast characters in different ways. For example, Brittany could be the innocent and kind - hearted Belle, and Artie could be the Beast who is initially grumpy but has a heart of gold. They could then perform songs from the Beauty and the Beast musical within the Glee club, adding their own Glee - style choreography.
The trailer can inspire fanfiction by showing new visuals. For example, if the trailer has a new look for the Beast's castle, a writer might create a fanfic where the castle has secret passages not shown in the movie. This adds an element of mystery to the story.
To modernize it, you could focus on themes like social media influence, mental health awareness, or gender equality. Also, change the style of the characters' clothing and the way they communicate to fit today's norms.
