The Dominator Portable Psychological Diagnosis and Suppression System (Japanese: 携帯型心理診断鎮圧執行システム、ドミネーター) or 45MW.TRG Dominator is the iconic firearm carried by enlisted Inspection and Enforcement officers of the MWPSB. This weapon is able to determine the identity of its holder, requiring authentication and wireless connection to The Sibyl System in order to operate, with each individual gun only heard by the user to which it is registered.
When the Dominator is aimed at a target, it continuously reads and sends psychological data ‒ the individual's Psycho-Pass ‒ which it sends to The Sibyl System for calculation of their Crime Coefficient. When this value exceeds a certain level, one indicating that the target is mentally unstable and likely to commit a violent crime, the gun will be operable. If the level does not exceed such 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 wirelessly to The Sibyl System in most circumstances.


Direct contact with the 45MW.TRG pulsed electromagnetic round is not advisable, and can result in death or severe injury. Following impact on a human target, the affected part will swell rapidly, culminating in total annihilation. What remains from a shot from a Dominator is a spray of blood and fragments of the corpse, possibly showing an eighteen-inch or more entry wound.
