Picador
this was the term used to describe the caste of wingless Geonosian drones who were employed as prison guards and animal controllers. Picadors were revered in that they maintained the collection of unusual beasts used in gladiator-style executions, such as acklays and nexu. The picador caste was unique in that a Geonosian from any other caste could become a picador if they could prove themselves in the battle arena.
