Begin by creating a unique setting. It could be an alternate version of Endsville where Brains has become the mayor. Then introduce how Billy and Mandy react to this new situation. You can also consider adding new characters that interact with the main three. This will help to expand the story and make it more interesting.
First, you should think about the relationship between Billy, Mandy and Brains. Decide if you want to focus on their friendship, rivalry or something else. For example, you could start with a situation like Billy accidentally breaking one of Brains' inventions that was important to Mandy.
To start a Billy and Mandy Brains fanfic, it's good to have a clear goal or plot in mind. Maybe it's about Brains creating a time - traveling device and Billy and Mandy getting caught up in different time periods. Outline the main events that will happen in your story, like the problems they face in each time period and how they ultimately solve them. Also, think about the dialogue. Billy's simple - minded yet endearing way of talking and Mandy's sharp retorts are key elements to capture in their conversations.
You can also start by introducing a new character who challenges their relationship. Maybe a new girl has a crush on Billy and Mandy gets jealous. In the heat of an argument to claim Billy as her friend (or more), she kisses him. This would create an interesting starting point for the fanfiction.
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.
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.
First, think about the characters. What makes Billy and Mandy unique? For Billy, it's his silly nature and for Mandy, her dark and serious side. Then, come up with a plot. It could be something simple like a day in their lives or something more complex like a mystery they need to solve. You can also add new characters or settings.
It's quite good. The comic has interesting plots and unique characters that make it enjoyable.
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.
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 popular 'billy and mandy fanfic' could be 'The Adventures of Billy and Mandy in the Enchanted Forest'. It takes the characters on a journey full of magic and mystery. Another one might be 'Billy and Mandy's Friendship Test' which explores their unique relationship 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.
