His older pre-rebuilt form, known as Withered Bonnie, has a damaged appearance, which is due to an attempted retrofit of the older animatronics that took place before they got scrapped for the newer models, such as Toy Bonnie. Like Withered Freddy, Withered Bonnie also has two buttons on his chest. His face has been gutted, with most of it being removed, revealing his endoskeleton mechanisms and dangling wires. His lower jaw remains, featuring more teeth than the original Bonnie possessed in the first game, although the jaw itself still appears to be functional as seen in his jumpscare from Help Wanted. His eyeballs are gone, exposing glowing red irises. His left arm is missing entirely, baring a tiny strip on the topmost section, with a mass of torn wires in its place. The red layering of his mouth has been removed, making his teeth seem longer than before. Withered Bonnie's right ear is mostly seen being folded, similar to a stereotypical rabbit. His suit has become tattered, particularly around the legs, and a few loose wires poke out of his body. The covering on his right hand and left foot have come off, revealing more of his endoskeleton. He also seems to have a bigger stomach, as it looks more rounded and bigger than his upper body. Also, his chin does not squash his bow tie now, and his suit seems to have changed to a darker shade of blue. Like the original Bonnie, Withered Bonnie also wears a red bowtie. Out of all the Withereds, he seems to be the most tattered, as he has no face apart from his jaw and has only one arm. In Help Wanted, Withered Bonnie's design remains unchanged, however, the most noticeable change is that he has a darker shade of purple.
Personality
As Withered Bonnie, he has a tendency to make face puns (in reference to the fact that his face is missing). He is also aware of the fact that he is damaged. His voice sounds pretty damaged and malfunctions frequently, as well as the ominous buzzing in the background. While Withered Bonnie enjoys making face puns and taunting the player about his scary appearance due to lacking a face, he is also shown to be quite saddened that he is the only animatronic to be missing a face, thus feeling left out and neglected. Despite this, he still remains confident even without a face, proving to himself that he is still worthy and more superior without one.
