One common theme is adventure. Foxy is often depicted as taking the reader on some sort of exciting adventure in the FNAF world, whether it's exploring the haunted pizzeria or trying to escape from other animatronics.
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.
Another theme could be the struggle of being in a relationship that is not considered 'normal' in the context of the FNAF world. There might be challenges like acceptance from other characters or dealing with the dangerous and spooky nature of the FNAF setting while being in a relationship.

As they spend more time together, a special relationship develops between them, which could be a friendship or something more romantic depending on how the author wants to write it.
