So hi uhm short thing before we start,
I am not really to deep in the Fnaf Fandom so sorry if it's fact wise inaccurate or some shit like that, I do not wish to be corrected of any factual mistakes as I know that I may or may not got things wrong. Also it's probably more based on the games ig
This was written at around 2am so I apologize for probably wrong grammar and missing words!
Another small thing, this is Cross-Posted on Ao3 and Wattpad under the same title :)
It was a rainy evening in Fazbear's Pizza, and a kid celebrated its birthday. A man standing in the back of the main dining room staring at those children and their parents, all laughing. Jealousy burning in the man's body. He was jealous of those parents who still got to see their children growing up. He lost two of his children. His middle because of an accident that his good for nothing oldest and his friends caused, and his youngest because of her love for a certain animatronic. It wasn't intentional, both weren't, why would he want to kill his own children? He couldn't kill even his oldest, tho he had a reason to do so. He couldn't handle the death of his oldest even though he might or might not deserved it. He cared for his children. He never would say it out loud. He was too stubborn for that.
After his first died, he already lost it trying out everything possible in his power to keep his other two children alive, and with him, he would even go as far as to kill for his experiments. His first kill was something harmless, you could say, a dog of a little girl. He was experimenting on that dog trying various things, even building to as far as building a new band of animatronics so it wouldn't come of as weird if he only wanted to build one that didn't really suit the theme of the current existing. The experiments, to his surprise, actually worked somehow.
His first actually kill on a human was his colleagues daughter. He found her crying outside of one of the Fazbear locations after a few kids threw her out for the jokes. His colleague seemed to be busy as he wasn't watching the kids. He got out of his car and walked up to her saying he will get her back inside but through the back doors. He walked her into an ally and said she needed to wait a short moment he had forgotten the keys. He didn't come back with keys, no, what he got from his car was a crowbar. He walked back to her now standing behind her and the moment she turned around.. *thud*. She fell to the ground like a stone. What a pity, he thought. Now his colleague could feel what it means to loose a child and the guilt for not watching after them. He sat her lifeless body besides a trash can and walked away like nothing happened.
He lo"ked back at the five children. Their parents clearly not watching. He put on the bunny head of the suit and walked over to them. They greet him happily and started to circle around him. He said he had a surprise for them, they just needed to follow him and as naïve as children are they did, following him into a cold dark room. After they all are in the room, closed the door behind locking it. Only one kid noticed it, a raven haired. The children where asking for the surprise and what it is, they got no answer all they got was a slight chuckle and him turning around. The children couldn't see very well, the only light source was flickering the entire time like the flash light of cameras. He now was holding something they couldn't really see what it was. He walked up to the group and.. *stab*. A scream could be heard. The rest of the bunch started all scream and crying. Scream all you want, the man thought, no one is going to hear you. One after another was brutally murdered, all screaming and crying, the last one was a raven haired boy, watching in horror as tears streamed down his face. The flashy lights made the scene much more gruesome. Blood was everywhere, the boy even had some on him. He was the last one to die but wished to be the first one, he didn't want to see his friends get killed but he also couldn't let any of his friends watch this horror. His last thoughts were if his dad already searched for him or if simply didn't care like always.
He needed to be careful with hiding the body's but he had an idea. He used the newly made animatronics as a hiding spot, only problem was that it were only four animatronics but five body's, then he remembered they had a scraped design of Fredbear somewhere in the back it had no endo skeleton so it be even better to hide a body inside, especially a small one. No one would think anything was hid in there.
He never thought of the consequences. Yes the police did investigate as soon as the parents reported that their kids were gone but they never found anything so they declared the children as dead. Over the span of a few months fewer and fewer people came, firstly because of the missing children and secondly, a horrendous smell that came from the stage and the back of the building no one knew where it came from but it smelled like something was decaying.
