Circus baby from the Five Nights at Freddy's series is a patient, composed, well-mannered and mysterious animatronic. She's a tragic, sympathetic villain. While helpful and kind on the outside, on the inside she is a broken and manipulative robot who will use others to advance her own goals. Due to the way she was built, she is capable of trapping others inside her stomach by opening her mid section, but recent upgrades allow her to not only trap adults but to trap them by swallowing them whole.
