Springtrap

Springtrap is the main antagonist and the only true animatronic in Five Nights at Freddy's 3. He is the only antagonist that can kill and give the player a Game Over, as the phantom animatronics can only jumpscarethe player and impair their vision and/or hearing.

Appearance
Springtrap is an early model of a Bonnie suit (as he is referred to asSpring Bonnie by the Phone Guy on Night 5 and by a girl in Night 4Minigame of Five Nights at Freddy's 4).

He is a heavily damaged rabbit animatronic of an 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. The exceptions to this are during his second jumpscare, the main menu, on CAM 15, his rare boot images, and Scott Cawthon's "Thank You!" image.

Close examination of Springtrap and the rare boot images depicting him show that there appear to be

human remains within the suit. When viewing the torso and other exposed sections of the endoskeleton, there are chunks of dark pink material that resemble human innards. In the boot images, Springtrap has his jaw open and is pulling the suit's head up, revealing a mummified-looking human head. The jaw and teeth of the head can be briefly seen during his second jumpscare and can also be seen when he's on CAM 15. It is revealed in the Night 5 minigame that these innards belong to Purple Guy after he was killed by the Springlocks within the suit.
