One common theme is the development of their friendship. Since they are roommates with very different personalities in the show, fanfics often explore how they get to understand and care for each other more deeply.
One great 'Wednesday x Enid fanfiction' is 'The Unlikely Bond'. It beautifully explores their growing friendship in Nevermore Academy. It has really interesting character interactions that stay true to their personalities from the show.
Friendship is a very common theme. Since they are roommates in the show, many fanfics explore how they become friends despite their very different personalities. For example, how Wednesday's dark and brooding nature contrasts with Enid's more bubbly and colorful personality, yet they find common ground.
An interesting plot. It could be something like a mystery they solve together, or exploring their different backgrounds and how they interact because of it. Maybe a story where they have to work together to overcome a common enemy at Nevermore Academy, which would bring out different aspects of their relationship.
One great 'Wednesday Addams x Enid Fanfiction' is 'A Strange Bond'. It beautifully explores their contrasting personalities. Enid's bubbly nature and Wednesday's dark allure are well - depicted as they navigate their friendship at Nevermore. It has some really touching moments that make you root for their relationship to grow.
You can start by looking on fanfiction platforms like Archive of Our Own (AO3). It has a vast collection of Enid and Wednesday fanfics. Just search for the characters' names, and you'll be presented with numerous options, ranging from friendship - focused stories to ones exploring more complex relationships between them.
Another theme is the idea of finding family in each other. Since they are both at Nevermore Academy, away from their own families to some extent, some fanfictions focus on how they become like a family to each other. For example, in a story I read, they celebrate holidays together in their own special way at the academy, creating new traditions. This theme of building a new family unit between them is really heartwarming.
Another theme is mystery - solving. Since Wednesday has a penchant for the macabre and Enid is always up for an adventure, fanfictions often put them in situations where they have to solve a mystery. It could be something related to the school's dark secrets or a strange occurrence in the town.
I also like 'The Midnight Adventure'. It's a story where Wednesday and Enid embark on an unexpected adventure in the middle of the night. The descriptions of their emotions and interactions are really vivid, and it gives a fresh perspective on their bond outside of the usual school setting.
One great Wednesday and Enid fanfic is 'The Roommate Chronicles'. It focuses on their daily life as roommates in Nevermore Academy, with a lot of humorous exchanges and the development of their friendship. It's really cute and well - written.
