What are the common themes in 'nightmare x nightmare fredbear fanfiction'?

One common theme is the exploration of darkness. Since both characters have rather menacing aspects, fanfictions often delve into the darker sides of their existence and how they interact within that realm of darkness.

I also know 'Fredbear and Nightmare: A Forbidden Alliance'. This one explores the idea of an alliance between them which is quite unexpected. It really plays with the characters' personalities and the overall atmosphere of the FNAF universe.

Maybe Killer wants to break free from his more violent tendencies, and Nightmare plays a role in that journey. It's an interesting way to explore their characters' depth.
