The Operators are designed to handle various tasks within the government agency Public Security Section 9, such as operating computers, carrying equipment within the agency's building, and even crewing aircraft. Physically they are gynoids, seen wearing office lady-style suits. In one episode, additional Operators are seen coming out of the walls to replace disabled units during a particularly strenuous task, suggesting that Section 9 has many in backup and that the units are switched regularly.
Their physical appearance is of a female wearing an office lady's suit. They have brown hair tied in a pony tail with brown eyes. It should be noted that they happen to be some of the most advanced Operators in the series besides Proto who is a prototype bioroid.
