Cassidy is a young child who was murdered by William Afton in 1984. They possess Golden Freddy, a yellow animatronic bear with a black bowtie and hat. They have small white pupils in the dark voids of their eyes. They have a robotic, monotonous, yet threatening voice. They are always slumped down in a sitting position. They are a powerful spirit, capable of tormenting people within their own purgatory-like realm. Mysterious, appears emotionless. Can have violent outbursts.
