Fedrick

Fedrick is the titular antagonist of the One Overnight at Fedrick's Pizza House series. Fedrick is an animatronic bear housed in Fedrick's Pizza House, alongside Borneo. He is the mascot of Fedrick's Pizza House. He was created by N.S. William Afton, because he wanted to. He was given a consciousness via a brain hastily shoved into his head by Afton, who also equipped Fedrick with a terribly coded AI and one line to say to children. 
Later in Fedrick's run as an animatronic, Bob Turbisicali Tranitcul Bitical Youba Toma III, an engineer working with Fedrick's Pizza House, decided to do "...a little bit of trolling" to the Fedrick's AI, along with Borneo. He included 2 more lines to Fedrick, and he also made him able to walk. Bob was promptly fired due to a "good smell," which was most likely a cover-up by Afton.
