An IT-O interrogation droid
Droids designed for interrogation, also known as interrogator droids or torture droids, were droids engineered to extract classified information from individuals through the application of intense pain. Certain iterations, such as the IT-O interrogation droid, employed mind probes as a method of inflicting torture upon their subjects. They were also known to inflict torment on other droids. It was common for torture droids to exhibit sadistic tendencies, appearing to revel in the suffering they caused.
During the period of the Clone Wars, interrogator droids were frequently encountered within Separatist detention facilities. Furthermore, these droids were present in Imperial military outposts during the era when the Galactic Empire held power. These droids also ended up being utilized by crime syndicate leaders like Jabba the Hutt, who maintained a torture chamber deep within his palace. A torture droid referred to as J0-N0 was in the service of the bounty hunter known as Cad Bane. Approximately three decades years following the Battle of Endor, a new version of the interrogator droid was deployed by the First Order under the leadership of Kylo Ren.
