Sister Location

About
William Afton and Henry Emily created this pizza place, where they had animatronics called Funtimes. The animatronics in the Pizzeria were: Circus Baby, Funtime Freddy, Bon Bon, Funtime Foxy, and Ballora.

All of them were built to kill children.

One of them in particular was Circus Baby, she was the main animatronic, she was also made inspired by Elizabeth Afton, William Afton's daughter. At the end of FNaF Sister Location nights, you can hear the voice of a little girl (aka Elizabeth Afton) asking her father (William Afton) to let her visit Circus Baby, however she never gained his permission.

But one night, William was not watching, so Elizabeth went to visit Circus Baby. Elizabeth was the only child in the room, so Circus Baby offered the little girl some ice cream, and when she tried to get the ice cream, she was pulled into Circus Baby's belly.

Besides the Funtimes, there is the animatronic called Ennard, he is an amalgamation of all the Funtimes. He also has several souls of children who were killed in the Pizzeria, including Elizabeth's, which is the soul that controls Ennard and Circus Baby.

After a while, Michael Afton goes to work at the Pizzeria, because he wanted to free Elizabeth's soul and the souls of the other children.

When Elizabeth hears that there is a new night guard, she devises a plan to trick Michael in order to escape from the Pizzeria.

At the end of the fifth night, Ennard and Circus Baby take Michael to Scooper Room, scoop him up and Ennard replaces Michael's organs.

After a few days, Michael vomits Ennard into a sewer. It is believed that after Ennard was vomited out, Elizabeth's soul was taken from Ennard, causing her to rebuild her body, which was called Scrapbaby. It is also believed that Ennard after being vomited on became Molten Freddy.

Also, after Ennard enters the sewer, we can hear "You won't die" coming from the sewer several times. After this, Michael Afton gets up.

Molten Freddy and Scrapbaby are seen in the Pizzeria in FNaF 6, along with Scraptrap and Lefty. Molten Freddy, Scrapbaby, Michael Afton, Scraptrap and Lefty are burned in that pizzeria, because Henry Emily created that place since he wanted to end all that history. It is believed that the souls were released and William Afton was sent to hell. It is also believed that Michael could have escaped the fire, but chose to die right there.
