Agonizer

Memory Beta, the wiki for licensed Star Trek content.

In the mirror universe, an agonizer was a device developed and used by the Terran Empire's Starfleet to punish their members for relatively minor offenses. More serious offenses - such as attempted mutiny or assassination - were punished with the agony booth, as early as the 22nd century. (ENT episode: "In a Mirror, Darkly")

In the 23rd century, agonizers were worn on a person's belt, and could be demanded by a superior officer in that officer felt a person had committed an infraction. When the agonizer was applied to a person's body it would cause intense pain which could bring a person to their knees. (TOS episode: "Mirror, Mirror")

By the 24th century, agonizers were refined to the point that they no longer needed physical contact with their victims to be effective. (DS9 episode: "Shattered Mirror")

In an alternate version of the mirror universe, agonizers were still used by the Terran Empire in the 24th century, and had been refined to the point that they were incorporated into the Starfleet insignia worn on a person's uniform. As Deanna Troi was head of ISS Enterprise-D security, a special agonizer was designed specifically to function with Geordi La Forge's VISOR. (TNG novel: Dark Mirror)

In the primary universe, an agonizer-like weapon was standard issue to Klingon personnel in 2268. One was used by Kang's landing party to deter an outraged Pavel Chekov on Beta XII-A. (TOS episode: "Day of the Dove")
