*Springtrap, previously known as Spring Bonnie, is the main antagonist of Five Nights at Freddy's 3 and the withered form of Spring Bonnie. He is possessed by William Afton, the main antagonist of the series. He appears in Five Nights at Freddy's VR: Help Wanted and Five Nights at Freddy's AR: Special Delivery. Springtrap is an early model of a Bonnie suit (as he is referred to as Spring Bonnie by the Phone Guy on Night 5 and by a kid in Night 4 Minigame of Five Nights at Freddy's 4). He is a heavily damaged rabbit animatronic of a dirty olive drab color.

A great portion of his right ear is missing with wires sticking out of the stump left behind. Springtrap's entire body is torn and tattered with gaping holes exposing caging and wires throughout, thus making Springtrap appear much more macabre-looking than any of the other animatronics from previous installments. While both hands and feet are attached and generally intact, his legs are entirely stripped from the mid-shin down, fully exposing endoskeleton metal and wiring.

From his right hand, half of the middle finger is missing. Both of Springtrap's eyes are properly set inside his head and appear to be a pale gray. However, during his jumpscare, they seem to take a pale yellowish hue, although this could just be because of the lighting.

A single button can be seen on his chest. While being an incredibly damaged version of Spring Bonnie, his bow tie is entirely missing. He does not typically open his mouth - instead, Springtrap wears a permanent, wide grin as the material surrounding his teeth has deteriorated.*
