Billy (Saw)

Billy is a puppet that has appeared in the Saw franchise. It was used by John Kramer (a.k.a. Jigsaw) to communicate with his test subjects by delivering recorded messages, often appearing on a television screen or occasionally in person to describe the details of the traps and the means by which the test subjects could survive. In the film series, before becoming the Jigsaw Killer, Kramer was believed to have created Billy to be given as a toy to his unborn child. However, Jill is shown to lose the baby inside her after being hit in the stomach by a swinging hospital door due to someone rushing past without looking. The unresolved anger caused to Kramer by this loss may have been a motive for making the puppet a vehicle for his instructions to his victims in the traps. The traps he created can be seen a manifestation of his anger with people who he feels don't appreciate having their life when his unborn baby was killed before having a life of its own.
