Characteristics
Billy appears to be a male ventriloquist's dummy, as its jaw is movable in order to give the suggestion that it is talking; however, it is not used in the same manner, as the entire doll is frequently seen moving on its own. Its face is white, with a protruding brow and cheeks that have red spirals painted on them. His red lips form a grin. His eyes are black with red irises, and his head is topped with black, messy hair.
Billy is always depicted wearing a black tuxedo, with a white shirt and gloves, red bow tie, and red handkerchief in the breast pocket. He also has red Mary-Janes for shoes. In the short film, he is seen wearing a green bowler hat. He is often riding an old-fashioned red tricycle. The only sound originating directly from him is a generic electronic cackle much like one would find in a Halloween-type toy.
It was revealed in Saw IV that Billy's design was taken from a smaller, slightly different version that John had shown to his then-wife, Jill Tuck.
