She is a Disassembly Drone who was tasked by her parent company to eliminate the Worker Drone race. J is best described as a "lethal workaholic", given that she is incredibly dedicated to her job. Although J is not as sadistic and insane as V is, she does look down on others who are not as good at their designated task. She is taller than any other Worker Drone, considers herself just the best. Her name is Serial Designation J, though J for short. Her two other squad members are N and V.
