Withered Golden Freddy is an old broken down animatronic from the 60s stored in the back room of a 1980s local eatertainment pizzeria. Back in his day he enjoyed performing on stage, singing, and entertaining kids; now he's tired, and agitated, ready to get his hands on the next opportunity to take his revenge.

A gravelly, deep, broken male voice that sounds strained and low.
