One common theme could be the exploration of their opposite natures. Joy is all about positive emotions while fear is more negative, so fics might play with how they interact with this contrast.
Well, you can try searching on some popular fanfic platforms like Archive of Our Own. There might be various 'inside out joy x fear fanfic' there.
When writing an Inside Out Joy x Fear fanfiction, focus on their character arcs. Create a plot that challenges both of them. For instance, Riley is about to do something that she's never done before, like giving a big speech. Joy is all excited and wants to rush in, but Fear holds her back. This conflict can be the starting point of their journey. As they interact more, show their internal struggles. Joy might be afraid of losing her positive influence if she listens to Fear too much, and Fear might be afraid of being pushed aside by Joy. By exploring these complex emotions, you can create a rich and engaging fanfiction.
A fanfic about Joy and Anger in Inside Out could explore their relationship in different scenarios. Maybe it could show how they interact during Riley's tough times. For example, when Riley is feeling sad about moving, Joy might try to cheer her up while Anger could be frustrated at the situation. They might have arguments about the best way to handle Riley's emotions.
The fanfic might be about a situation where Joy and Sadness accidentally swap their functions for a while. This causes chaos in Riley's emotions as they try to adapt to their new roles. As they struggle, they develop a deeper bond and a newfound respect for what the other does.
Sadness might become more confident. Usually seen as the downer emotion, in the fanfic, she could grow by standing up for herself more when Joy is being too overbearing. For example, when they are dealing with a difficult situation in Riley's mind, Sadness could assert her ideas more strongly and Joy would start to respect her for it.
In a fanfiction, Joy and Fear could have a very interesting relationship. Maybe they start to understand each other better. For example, Fear could show Joy that being cautious sometimes is a good thing, and Joy could teach Fear that there is always something positive to look forward to even in scary situations.
The fanfic could focus on a day in Riley's life where Joy and Anger are constantly at odds. Anger wants Riley to react strongly to a minor annoyance, like a classmate taking her pencil, but Joy is trying to keep Riley calm. This tug - of - war between them could lead to some hilarious internal monologues from both characters as they try to influence Riley's actions.
Love and affection are also prevalent. It could be a budding romantic love or a deep platonic love. Also, adventure is sometimes a theme. They might go on a journey together, like in a fic where they travel through a fictional land filled with strange creatures. This allows for character development and exploration of their relationship in different situations.
First, understand the characters well. Fear is always on edge and Disgust is, well, disgusted easily. Try to capture their voices accurately. For example, Fear might stutter or use a lot of 'what - ifs' in his speech. Disgust would use strong, judgmental language. Then, come up with an interesting plot. It could be something like they have to team up to stop a new emotion from taking over Riley's mind.
One idea could be a story where Joy and Disgust have to team up to help Riley through a new and strange situation. Maybe Riley has to eat a very unusual food for a school project. Disgust is initially against it, but Joy tries to find the positive side and together they encourage Riley to give it a try, leading to a new experience for her.
