Charlie is quite interesting. She has a connection to the animatronics that is central to the story. Then there's John, who is constantly trying to uncover the truth. His determination makes him stand out.
One interesting aspect is the character mash - up. Seeing RWBY characters interact with FNAF animatronics is quite unique. For example, Ruby's energetic and positive personality against the spooky, menacing nature of the animatronics.
There are several interesting characters in the fnaf books novel. Charlie stands out as she is constantly exploring the secrets related to the animatronics. Her character development is intertwined with the overall mystery of the story. The Phone Guy is another one. His messages are full of mystery and seem to hold the key to understanding some of the more sinister aspects of the story. The kids, whose spirits are trapped in the animatronics, add a layer of tragedy and mystery. Their backstories and how they are connected to the events are very engaging.
The most interesting part is the backstory. It's a complex web of events that led to the current state of the animatronics. There are secrets about the past owners, the murders that took place in the pizzeria, and how the animatronics came to be haunted. All these elements combine to create a very engaging story.
Chica is also quite terrifying. With her beak and those strange movements. She seems so unpredictable. Sometimes she just stands there staring, and other times she charges at you without warning. And Bonnie, with his purple fur and those red eyes. He has this menacing look that can send shivers down your spine. He's often seen lurking in the shadows before making his move.
The Purple Guy is a really well - known character in fnaf fan fiction. His mystery and his actions in the lore of the original game make him a prime target for fan - created stories. He's often the source of a lot of the horror and intrigue in these fictions. Also, the Crying Child from the game's backstory is a popular character as well, as his story is quite tragic and lends itself well to exploration in fan fiction.
Well, aside from the main animatronics like Freddy, Bonnie, Chica, and Foxy, some of the human characters can be really popular in FNAF Stories Fanfiction. For example, Mike Schmidt from the games is often a central character in fanfictions. His experiences working at the haunted pizzeria can be elaborated on in many different ways. Also, the Phone Guy, with his cryptic messages in the games, can be a really interesting character to develop in fanfiction. And of course, any new original characters created by fanfiction writers themselves can also gain popularity if they are well - written and add something unique to the FNAF Stories Fanfiction universe.
