Another aspect of fanfictions with these two could be centered around competition. Since they are both animatronics in the same pizzeria, they might compete for the attention of the children or for who gets to be the star of the show. This could lead to some humorous situations, like a dance - off or a race through the pizzeria to see who can reach a certain area first.
Another theme is adventure. Fanfic writers like to take them out of their usual pizzeria setting and send them on exciting adventures. This could be exploring new areas in the FNAF world or even going to places outside of it. It gives the characters a chance to grow and develop in different situations.
Common themes in 'toy bonnie x foxy fanfic' often include cooperation. Since they are both characters in the same universe, they may team up to face challenges. Also, discovery can be a theme, like they discover new things about each other or their world together. It's also possible that there are themes of rivalry that turn into respect over time.
One idea could be that Foxy and Toy Bonnie are from different 'groups' in the animatronic world. They initially have misunderstandings but gradually discover they have a shared love for music. They start to secretly meet and create their own unique tunes together, which then leads to a newfound friendship and they have to face the reactions of the other animatronics.
A more emotional plotline could be about acceptance. Toy Bonnie might initially be a bit snobbish towards Foxy because he is an older model. But as they go through various situations together, they learn to accept each other's differences and become good friends. This could involve moments of conflict and then resolution as they grow to understand one another.
Their relationship could develop through a shared mystery. For example, they find a strange object in the pizzeria that seems to have some sort of power. They team up to figure out what it is and where it came from. This shared goal brings them closer as they exchange ideas and theories.
The settings in foxy x bonnie fanfiction also vary. It could be set in the familiar, spooky pizzeria we know from the game, or the author might take them to new, uncharted areas.
