One of the great fanfictions might be those that explore their unique relationship within the horror - filled world of FNAF SL. It could be about how they interact during the 'nightshifts' in the game. Maybe there's a fanfic where they team up against some common threat in the animatronic world.
The male OC might be an inventor in the fanfiction. He could try to upgrade FunTime Foxy, which would lead to some interesting interactions. FunTime Foxy might be initially skeptical but then come to trust the male OC.
It could be about Foxy and Chica providing comfort to each other in the spooky world of FNAF. Maybe they're facing some sort of threat, like the night guard, and they find solace in their friendship. Foxy might be scared of the new security measures, and Chica could be there to cheer him up, telling him not to worry.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of FNAF - related fanfictions, and you're likely to find some good ones about Funtime Freddy and Funtime Foxy there. Just use the search function and type in their names.
One thing that makes it interesting is the setting of the FNAF world. It's a dark and spooky place full of mystery. Foxy and Chica's comfort story against this backdrop can be really engaging. For example, they might be trying to comfort each other during a power outage, which is a very tense situation in the FNAF lore. Also, the exploration of their personalities beyond their basic traits in the context of providing comfort can add depth to the fanfic.
In FNAF fanfiction, FunTime Foxy and a male OC can create really interesting stories. The male OC could be a new night guard, for example. He might start off being scared of FunTime Foxy but then gradually understand the animatronic's true nature. This could lead to a unique friendship or an adventure where they face other threats in the spooky world of Freddy Fazbear's Pizza together.
The plot could be a love story in a really unique way. Withered Bonnie, with his worn - out appearance, might be initially shunned by Toy Chica. But as time goes on, she sees his kind 'heart' (if animatronics can have such a thing). They could then have a relationship that defies the expectations of the other animatronics. For example, they might share secret hiding places in the pizzeria and have little 'dates' where they just sit together and exchange their experiences.
The Male OC could interact through trying to communicate with FunTime Freddy. For instance, if the OC is a curious person, he might start by asking Freddy simple questions, even if Freddy only responds with his pre - programmed phrases at first. This could lead to a sort of one - sided conversation that gradually evolves.
Good characterization of Funtime Freddy is key. He should have the right mix of his creepy and somewhat endearing traits. The story could explore his motives and how he interacts with the reader. Maybe he has a hidden side that only the reader gets to see. Also, a well - developed plot that keeps you on your toes. It could involve mystery, like something strange going on in the pizzeria that the reader and Funtime Freddy have to figure out together, which can be really exciting and engaging.
At first, it might be a reluctant partnership. Maybe they are forced to work together to survive some kind of threat in the pizzeria. During this time, they start to see the good in each other. Toy Chica might notice how Withered Bonnie is protective, and Withered Bonnie might see Toy Chica's intelligence. This mutual admiration could then turn into a deeper relationship over time as they continue to interact and support each other.
