Withered bonnie

Bonnie returns in the second game as one of the antagonistic animatronics. He has two buttons added to his chest and is also the most damaged of all the older animatronics. His face has been gutted while his lower jaw remains, featuring more teeth than he possesses in the previous game as well as glowing red irises. His left arm is missing entirely, with a mass of wires in its place. 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 his entire left arm has come off, revealing his endoskeleton and wires. He also seems to have a bigger stomach than before, as it looks more rounded and bigger than his upper body. His chin also doesn't squash his bow tie now. It is explained that the management tried to have Bonnie and the old animatronics retrofit but this was scrapped in favor for the newer, toy models.

Bonnie starts with the rest of the older animatronics in the Parts/Service Room. He seems to travel to the Main Hall and then heads to the room just outside the Security Office, staring at the player just from the outside. Afterwards, he then travels to the Left Air Vent to get into the Office and attack, though can be warded off with the Freddy Fazbear Head.
