This paper model is a full size Dominator (Dominator Portable Psychological Diagnosis and Suppression System or the 45MW.TRG Dominator), the iconic handgun carried by enlisted Inspection and Enforcement officers, based on the Japanese anime television series Psycho-Pass, the papercraft is created by Wong Hidayat. The size of finished model is about 33 (L) x 3,9 (W) x 15,8 (H) cm.
The gun is able to determine the identity of its holder, and requires authentication and wireless connection to the Sibyl System in order to operate. Also, each individual gun can only be heard by the user currently registered to it.
When the Dominator is aimed at a target, it continuously reads and sends psychological data ‒ Psycho-Pass ‒ about the person on which it is focused to the Sibyl System for calculation. When this value exceeds a certain level ‒ indicating that the target is mentally unstable and more likely to commit a violent crime, the gun will be able to fire. If the level does not exceed fixed levels, the muzzle will not open and a safety device will be activated to prevent the user from pulling the gun's trigger. The gun is unable to work when it is not linked wireless to the Sibyl System in most circumstances.
Before the gun fires, the muzzle opens up to reveal a complicated mechanism inside, part of which is used to read the suspect's criminality. When the gun does fire, it lets out a bullet the color of sky blue. It is voiced by Noriko Hidaka. The gun has three modes: Non-Lethal Paralyzer, Lethal Eliminator, and Destroy Decomposer.
