Berellian

When Lieutenant Commander Data takes temporary command of the USS Sutherland during the Klingon Civil War, his first officer on the Sutherland, Lieutenant Commander Thomas Hobson, argues that, as an android, Data is out of place commanding a Federation starship. Hobson compares the presumed incompatibility of Data's nature, and his assigned duty (or function) as a Starfleet commander, to that presented by a hypothesized Klingon counselor or Berellian engineer; "they're just not suited for those positions."
