An IT-O interrogation droid
Droids designed for interrogation, also known by the names interrogator droids or torture droids, were droids engineered to extract confidential information from individuals through the application of severe pain. Certain versions, for instance the IT-O interrogation droid, employed mind probes as a method of torturing their subjects. They would frequently inflict torment on other droids. These torture droids often possessed cruel dispositions, seemingly relishing the suffering they inflicted on others.
During the Clone Wars, interrogator droids were a frequent sight within Separatist detention facilities. They could also be located inside Imperial military bases during the period of rule by the Galactic Empire. Furthermore, these droids ended up in the possession of criminal leaders, such as Jabba the Hutt, who maintained a torture chamber deep within his fortress. A torture droid referred to as J0-N0 was employed by the bounty hunter Cad Bane. Approximately three decades (years) following the Battle of Endor, the First Order, under the leadership of Kylo Ren, made use of a new iteration of interrogator droid.
