For a Beetlejuice musical fanfic, you could have a plot where the living characters are able to temporarily cross over to the world of the dead in a more controlled way. This could lead to all sorts of chaos and hilarity as they try to navigate the strange rules and customs there. They might have to participate in some sort of death - world competition, like a dance - off against the dead spirits. And Beetlejuice could be their reluctant guide, constantly trying to trick them while also helping them out of his own self - interest.
One idea could be to explore Beetlejuice's backstory in more detail. Maybe show how he became the mischievous spirit he is. Another could be a love story within the Beetlejuice musical universe, like a character falling in love with a ghost. Or perhaps a story where the characters have to deal with a new, even more powerful supernatural threat.
In the fanfiction, a possible plot could be that Beetlejuice has a bet with another character that he can make Adam do something really out of character, like break a major rule in the afterlife. As Beetlejuice tries to get Adam to do this, Adam starts to learn more about himself and his own capabilities. Another idea is that there is a magical object in the musical world that Beetlejuice and Adam both want for different reasons. They start off as rivals for it but then realize they can achieve more by working together. And, there could be a plot where Adam gets lost in a strange part of the afterlife and Beetlejuice has to find him, during which they both grow as characters.
One idea could be to explore what would happen if Anastasia had a secret talent for painting. In the fanfic, she could use this talent to create portraits of the people she meets during her journey, adding a new dimension to her character. Another plot could involve a love triangle between Anastasia, Dmitry, and a new character who enters their lives, perhaps a nobleman from a neighboring kingdom. It would create a lot of drama and tension. Also, a plot where Anastasia discovers a long - lost family heirloom that has special powers or significance could be really engaging.
I think Beetlejuice is the top choice. He has such a unique personality, full of mischief and a desire for chaos. But also, Delia, with her new - age beliefs and her somewhat out - of - touch nature, can be really fun to explore in fanfic. You can put her in all sorts of strange situations in the Beetlejuice world and see how she reacts. Additionally, the sandworm could be an interesting focus. It's this huge, menacing creature, but there could be more to it, like a hidden gentle side or a backstory about how it came to be in the underworld.
Perhaps a plot where Lydia and Beetlejuice accidentally swap personalities. This would lead to all sorts of comical and spooky situations. Beetlejuice in Lydia's body would have to deal with school and her family, while Lydia in Beetlejuice's body would have to handle the chaos of the Netherworld. They then have to find a way to switch back before it's too late.
The relationship between the main human characters and their journey through the strange world of the Beetlejuice musical is also a top story. They have to deal with Beetlejuice's antics while trying to achieve their own goals, like the young girl trying to come to terms with her new situation in the afterlife. It's a story full of humor, spookiness and self - discovery.
A plot could involve Lydia inviting Beetlejuice to a human party as her plus - one. Beetlejuice has no idea how to act at a normal human gathering and causes all sorts of mayhem, from scaring the guests to turning the party food into strange and otherworldly delicacies. Meanwhile, Lydia has to keep him in check while also trying to show her friends that he's not as bad as he seems. Or perhaps there's a new ghostly threat in the afterlife that only Lydia and Beetlejuice can stop together. They have to put aside their differences and work as a team, which is difficult given Beetlejuice's self - centered nature.
One possible plot idea could be that Lydia is initially hesitant about the kiss. Maybe she's conflicted because Beetlejuice is from another world and she's not sure if she should get involved. But as the story progresses, she realizes there's a deeper connection between them that goes beyond the strange and spooky exterior of Beetlejuice. Another idea could be that the kiss is a result of a magical spell gone wrong. They end up kissing to break the spell that has put their world in jeopardy.
You could write a fanfiction where Cal, the grumpy diner owner, has a change of heart after a near - death experience. He starts to be more kind and understanding towards the waitresses. Or, a story where Jenna meets a famous pastry chef who challenges her to create a new and unique pie for a big competition, which could test her skills and creativity.
One idea could be to explore what would happen if Bella was a vampire from the start. She could have her own set of powers and a different dynamic with the Cullens. Another plot could be a musical adaptation of the Volturi's backstory, with dark and dramatic musical numbers.
Well, in 'Avengers the Musical Fanfiction', a great plot idea might be the Avengers facing a new villain who uses music as a weapon. They then have to use their own musical powers or talents to defeat the villain. It could also be interesting to see a plot where the Avengers are transported to a musical dimension and have to find their way back while dealing with the strange rules of that world. They could sing about their homesickness and determination to return.
