"I will put you back together"...

Before the bite and before Fredbear's Family Diner opened.
Mr. William Afton, which is a father and a not really known murderer yet, made an underground facility. One room in that facility is a private area, it is a security room where he can see his children's every single movements. Even though he is a murderer, he never thought of killing his own children. But he likes experimenting them.

He has three children, Michael, Cassidy, and Elizabeth.
Michael is the oldest, though he likes making fun of his little brother, Cassidy. But that was before the accident.
Cassidy is the youngest of the siblings, he has a great fear of animatronics. He is also the victim of the bite.
Elizabeth is the middle child, she is a playful little girl, sometimes she also likes making fun of her little brother, but not everytime, unlike Michael.

After the bite, Mr. Afton built an animatronic for his little daughter, though he never let her get too near to it. It is made in image of his daughter's bestfriend for her to like it. He named the animatronic as Baby, referring to his daughter since she's the youngest now after Cassidy died. Sooner, he called it Circus Baby.

Soon, he built more animatronics and made a pizzeria called Circus Baby's Pizza World but the grand opening of the pizzeria got cancelled 'cause of a gas leak incident.
An entrepreneur asked William questions about the animatronics
"There's no doubting what you've achieved on a technical level. These are clearly state-of-the-art. There are just certain design choices that were made for these robots that we don't fully understand. We were hoping that you could shed some light on those" the entrepreneur says as they ask Mr. Afton.
"She can dance, she can sing! She's equipped with a built-in helium tank for inflating balloons right at her fingertips. She can take song requests. She can even dispense ice-cream." Mr. Afton answered.
"With all due respect, those aren't the design choices we were curious about, Mr. Afton." the entrepreneur said telling Afton that they didn't got the answer they're wanting him to say.

The animatronics were actually made for two different purposes: entertaining and kidnapping. They entertain kids until there is one left, and if no one's around, the robot will kidnap the last kid.
Sometimes they go to nearby birthday parties and do their jobs. And since the pizzeria is no use anymore, Mr. Afton just kept the animatronics at the underground facility, each of them have their own rooms; Circus Gallery for Circus Baby and her Bidybabs, Ballora Gallery for Ballora and her Minireenas, Funtime Auditorium for Funtime Foxy, and the Breaker Room for Funtime Freddy and his Bonnie hand puppet. William decided to make the facility an entertainment place and named it Circus Baby's Entertainment and Rental.

One day, Mr. Afton and his daughter, Elizabeth, visits the facility. Mr. Afton's daughter kept on telling him to let her play with the animatronics, specially Baby. But Mr. Afton didn't allow her. For a little while, kids are starting to come, they seemed to be so happy, they are playing and running around with their friends, some are just watching the animatronics.

Then for a while, they went to the Circus Gallery, where Circus Baby is. Some kids were afraid of the robot, some are playing with her and watches her sing, some also request her to make balloons. 
Mr. Afton and his daughter just kept roaming around, Elizabeth saw Baby making balloons and giving it to the children so she says "Daddy, she can make balloons! Have you seen her make balloons? Oh Daddy, let me go play with her..", and so, Mr. Afton still did not allow her. But every five minutes, his daughter keeps asking him to play with Circus Baby.

One hour later, William is walking around the facility, not noticing that his child is no longer in his grasp, he looks around worriedly and trying to find her. He keeps on trying to find his litlle daughter until he heard a familiar scream coming from Circus Gallery, "LIZZY!!?" the worried father immediately runs toward to the gallery. But he was too late, he took a glance to the tall animatronic, its stomach filled with the blood of his daughter. "No..no.." he groaned and runs toward his own creation and punches its stomach,  "NO!!".
