As Withered Freddy, he is the older, withered incarnation and the first engineered model. He, along with the four other older animatronics have all fallen into severe disrepair, and he is replaced by his newer counterpart for the "improved" Freddy Fazbear's Pizza, Toy Freddy. It is explained that he has gone through an attempted retrofit, but was left unfinished after the management chose to make Toy Freddy (much like the other original animatronics being replaced by their respective counterparts). Out of all of the original animatronics, Withered Freddy seems to be the least damaged, with only a few tears through his body. This version of Freddy is later retrofitted and redesigned into the classic Freddy for the events of the first game.
Withered Freddy's overall appearance is unchanged, but small differences are visible - mainly the buttons added to his chest, and a more visible stitching on the underside of his arms. Most notably, however, is the damage on his arms similar to that of Foxy's, showing parts of his endoskeleton. He also seems to be lacking kneecaps. Additionally, both of his knees are damaged; with visible wires poking out of his left knee. His body segment is also smaller and his hat is removable, as it is seen sitting on the floor next to him in the Parts/Service room. It should be noted that he still holds a microphone. This time around, Withered Freddy has an upper set of teeth, while his head appears far blockier. In addition to this, part of Freddy's endoskeleton teeth are also slightly visible. His freckles are gone, his eyebrows are thinner, and he has embossed inner ears. His eyes are in a slightly different position, meaning one of his eyes go up and down, and also seem to have been placed deeper within the mask. Also, his muzzle appears to be smaller and much rounder. The reason for his disrepair is due to neglect by the company and the fact that he is simply used as spare parts for the newer animatronics. Withered Freddy's pupils can sometimes be seen illuminating white glows. In Help Wanted, Withered Freddy's design remains unchanged, however, the most noticeable change is that he has a darker shade of brown.
Personality
As Withered Freddy, nothing much is known about his personality, however, Withered Freddy shows that Freddy has a benevolent side as it's shown in Five Nights at Freddy's 2 that he appeared to be protective of children as he tried to save them from his killer, William Afton, in the SAVETHEM minigame, however, he was too late.
