Good character development is key. Since it's a crossover, seeing how the FNAF nightmare characters interact and change in the new setting is important. For example, if they cross over with another horror franchise, how do they respond to new threats or allies? Another feature is a unique plot. It shouldn't just be a rehash of the original FNAF nightmare story but something that takes advantage of the crossover concept, like a new mystery or conflict.
One great fnaf nightmare crossover fanfiction is 'The Nightmare's Alliance'. It combines the terrifying elements of FNAF nightmares with other popular horror universes. The characters' interactions are really well - written, making it an exciting read.
One common theme is redemption. Often, the human is portrayed as a catalyst for Nightmare Moon's possible redemption. Another theme is the clash of two different worlds. Since a human comes from a very different reality than Nightmare Moon, the exploration of how these two worlds interact is quite frequent.
One interesting 'Nightmare Moon and Human' fanfiction is 'A Meeting with Nightmare Moon'. It tells the story of a human who accidentally stumbles into the world where Nightmare Moon exists. The human's journey of trying to understand and perhaps even befriend Nightmare Moon is full of unexpected twists.
The nightmare world and the human world mentioned in novels usually referred to fictional worldviews that could be set by the author or editor, or created through imagination or inspiration. In different novels, the settings of these two worlds may be different, but they usually represent different meanings and values.
The Nightmare Realm was usually described as a mysterious and strange world filled with supernatural powers and dangers. In this world, humans were usually unable to sense or control these forces and could only passively face them. The monsters and magical items in the nightmare world were usually supernatural existences that could be extremely threatening and dangerous.
The human world was usually seen as a real world, the human society described in novels. In this world, humans had all kinds of emotions, desires, and conflicts. They also faced all kinds of challenges and difficulties. The characters, plots, and storylines in the human world were usually influenced and limited by the real world, but they could also be imagined and created.
The nightmare world and the human world mentioned in the novel usually represented the meaning and values that the author or editor wanted to express. It could be horror, science fiction, fantasy, romance, and so on.
Definitely Freddy and Bonnie are among the most popular. But also Golden Freddy, when turned human, has an air of mystery around him. People are drawn to his story because in the original FNAF, he had a lot of lore. When human, his backstory can be further explored, like what made him so special as an animatronic and how that affects him as a human. And the same goes for the Puppet. It has a deep and complex backstory in the FNAF world, and as a human, there are many directions a story can take with it.
Freddy is often a popular character. His human animatronic form might be depicted as having a mysterious past, like he was once a normal human who was transformed into an animatronic against his will.
One interesting concept could be the backstories of the human animatronics. For example, how they came to be in the form of animatronics. Maybe they were part of some experiment gone wrong in a spooky pizzeria.
Freddy is often a very popular character. In the human animatronic version, he might be seen as the leader, with his charm and charisma still intact even in his new form. He could be the one making important decisions for the group of human animatronics.
In 'FNAF Turned Human Fanfiction', a great plot idea could be the human - turned - animatronics trying to find a way back to their original forms. They could face challenges like discrimination from humans who remember them as terrifying animatronics. Also, their new physical forms might have some special abilities or weaknesses that add to the story.
