Most Billy x Mandy fanfic often has a spooky or supernatural element, just like the original show. It usually centers around the odd couple - Billy, the dim - witted but good - hearted boy, and Mandy, the cynical and somewhat menacing girl.
Granny from the series could be a great addition. She could act as a sort of wise advisor to Mandy and Billy, providing them with valuable advice based on her own experiences. Her no - nonsense attitude could also add some humor to the story, especially when she scolds Billy for his silly mistakes or when she encourages Mandy to be more open - hearted.
Perhaps they could be in a modern - day high school setting where Mandy is the cool, mysterious girl and Billy is the nerdy but kind - hearted boy. They get paired for a school project and at first they clash because of their different personalities. But as they spend more time together, they find common interests like a love for old horror movies and start to develop feelings for each other.
One common theme is friendship. Despite their differences, Billy and Mandy's friendship is always a central part of the fanfics. Another theme is adventure. They often go on various adventures together in the fan stories.
One common theme is the exploration of their unique relationship. Given their different personalities in the show, fanfictions often play with how they interact and grow closer. Another theme could be adventure, where they go on some crazy quests together.
Well, I've heard of a fanfic titled 'The Unlikely Bond of Billy and Mandy'. This one focuses on how their relationship has developed over time, from their initial meeting to becoming inseparable friends. It also has some really cool sub - plots involving the other characters from the show. It shows how Billy's naivete and Mandy's cold - heartedness play off each other in different situations.
One common theme is the clash of different personalities. Billy and Mandy have very distinct personalities compared to the RWBY characters. So, there's often a theme of how they adjust to each other. Another theme is the exploration of new powers. Since they are in a new universe, they might discover new abilities or ways to use their existing ones.
Well, obviously Billy and Mandy are the main characters. Billy is often the goofy and naive one, while Mandy is more cynical and in control.
One idea could be to explore what would happen if Billy's stupidity was magically transferred to Mandy for a day. It would completely disrupt their usual dynamic. Mandy is used to being in control and smart, and suddenly having Billy's lack of understanding would put her in all kinds of comical and difficult situations.
A possible plot is that the kiss was part of a bet. Billy lost a bet to Grim and as a result had to kiss Mandy. But then, unexpectedly, Mandy didn't mind as much as she thought she would and it led to a series of comical and heart - warming events in their little group.
There could be various stories about Billy and Mandy. Maybe they go on an adventure in a magical forest where they meet strange creatures and have to solve puzzles to find their way back home.
