Freddy Fazbear's Pizzeria was initially called Fredbear's Family Diner, as per Phone Guy in Five Nights At Freddy's 2. He also states that the original restaurant, this so-called diner was a local family restaurant till it was branded and franchised as a pizza chain.

One of the hidden altered posters in the game also gives further insight into the history of the first restaurant. Apparently, a man dressed in an animatronic suit lured a few children in the back of the eatery and murdered them. While the suspect was apprehended, none of the children's bodies could be recovered. The game later points to antagonist William Afton being the serial killer.
