Hello, hello? Uh, welcome to the Complete Theory page.
In the 80’s, Fredbear’s Family Diner was born, putting a new spin on family entertainment. The unique restaurant featured 2 cutting-edge animatronics; a bear and a rabbit. The restaurant ran successfully until around early 1987, at which point the diner’s robotic duo couldn’t keep up with the onslaught of birthdays and bookings. Management made the decision to invest a very large sum of money into a new animatronic gang: Freddy, Foxy, Bonnie and Chica, at which point things started to go downhill.
The new animatronics ate up so much money that the diner had to fire the management team to keep up with the costs. This had quickly proven to be a mistake as the facility and the animatronics quickly became a wealth of disgusting viruses, grime, and the like. Management severely underestimated how insanely messy kids can be. *shudder*
A little later in the year, a party was booked for a small child’s birthday. Almost the whole neighborhood was invited. Unfortunately, the child was very afraid of the animatronics. He’d never seen anything like them. His big brother mocked and bullied him for this to the point where he and his friends put him right in the face of Golden Bonnie, who, due to his lack of service, misunderstood the action and bit into the boy’s frontal lobe. The incident brought a lot of infamy to the Fredbear name, and was quickly dubbed the Bite of ’87. The child was in a comatose state for five nights after the incident, and passed away at 6:03 AM the next day. Due to all the suspicion and current state of the animatronics, the restaurant closed its doors not much later.
The gameplay of Five Nights at Freddy’s 4 occurs within the child’s coma, with the nightmare animatronics being devilish versions of his prior animatronic terrors. the minigames are reflections of his activities leading up to the bite. This makes sense because the player can see the flowers, IV, etc. and because the final cutscene plays a flatline at the end, implying that the child died. The line “Can you hear me? I don’t know if you can hear me” also hints that the child is in a coma.
On November 1st later that year, The company reopened as Freddy Fazbear’s Pizza in a new location and with a new cast of “toy” animatronics, essentially kid-appropriated versions of the previous ones. The old animatronics were kept in the back room and used for parts because no buyer was found. Unfortunately for Fazbear’s, yet another horrible incident occurred: The previous security guard (Purple Guy) lured 5 children into the restaurant’s safe room and murdered them. Shortly after, he was haunted by hallucinations of the children and killed himself by getting into the old malfunctioning Springtrap suit. On top of that, the new models were reported by security guards to have malfunctions, so the unlucky restaurant had to close once again.
Then, in 2003, the restaurant opened again, this time with a much smaller budget. Don’t really have much to say here, this is where the first game takes place.
Thirty years later, FNaF 3 takes place. The minigames are a way of freeing the souls of the children and reflecting on Purple Guy’s actions.
Hope this theory cleared some stuff up, if you find a defect please just say so in the comments.
