To start writing an Emmerdale OC fanfiction, it's essential to have a plot in mind. It could be a simple plot like your OC trying to make friends in the village or a more complex one such as uncovering a long - hidden mystery in Emmerdale. Write a rough outline first, including the main events and how your OC will be involved in them. Don't be afraid to let your OC have their own unique voice and perspective, as this will make your fanfiction stand out.
First, you need to develop your OC. Decide on their appearance, personality, and backstory. Are they kind - hearted or a bit of a troublemaker? Where are they from? Once you have a clear picture of your OC, think about how they will fit into the Emmerdale world. You can start by introducing them in a familiar setting in the village, like at the local shop.
