Bonnie from FNAF could be a great crossover character with Foxy. They already have a connection in the FNAF universe, and in a crossover, they could have new adventures together, perhaps in a different time or place.
Obviously, Foxy and the reader are the main characters. Foxy is the animatronic character with its own personality and backstory within the FNAF universe. And the reader is the character through whose perspective the story is often told.
Baby, on the other hand, is usually seen as more calculating and intelligent. She can be very manipulative when she wants to be. In the fanfiction, she might use her intelligence to plan things for herself and Funtime Foxy, like how to get access to certain areas or resources.
Even the kids who visit the pizzeria could be main characters. They might be the first to notice that Foxy is acting strange. One of the kids could be really attached to Foxy and be very worried about him. This kid could try to get the staff's attention to help Foxy or even try to comfort Foxy on their own.
Well, 'funtime foxy x foxy fanfic' could potentially be a fanfiction that focuses on the interactions between Funtime Foxy and another Foxy - like character. It could involve elements like their personalities, how they meet, and what they do together in the fictional world created by the author. Maybe it's set in the Five Nights at Freddy's universe, where they face challenges or have some unique experiences.
Foxy in these fanfictions is frequently portrayed with a sense of loyalty. He might be the type to stay by the Reader's side through various dangerous situations in the FNAF world. His broken - down appearance in some versions of the game also adds to the pathos in the fanfictions. Writers often play on his 'outcast' status among the other animatronics, which can make for some interesting relationship dynamics with the Reader.
One possible scenario could be that in the fanfic, Foxy runs away because he's scared of something in the pizzeria. Maybe he's afraid of the new security measures that are being put in place which he doesn't understand. As for the Foxy x Reader part, perhaps the reader is the only one who can understand Foxy's distress and tries to find him.
Adventure is also a frequent theme. Many fanfictions put them in different situations where they have to go on quests or overcome obstacles. For instance, they might be exploring an old, abandoned place full of secrets. This not only tests their skills but also strengthens their bond. And in some stories, they might encounter other characters that are either helpful or a hindrance to their adventure.
