J is a Disassembly Drone who was initially believed to have been created and sent out to Copper 9 by the interstellar company, JCJenson, to achieve the goal of wiping out all Worker Drones. Serial Designation J has the distinctive features of a female Disassembly Drone, with wide hips and shins tapered to a point. She has silver hair styled in high-sleek twin silver-colored ponytails, tied with black ribbons. Like other Disassembly Drones, she has neon yellow eyes and a black headband adorned, as well as a long, thin black tail ending in a large syringe also filled with Nanite Acid. Her attire consists of a short-sleeved black shirt with side pockets under it, a black leather belt giving it as a skirt, a dark yellow shirt beneath her blazer, and a tie, giving her the appearance of professionalism, especially in comparison to the other two members of her squadron, V and N. J is best described as a "lethal workaholic," as she is incredibly dedicated to her job - even using corporate jargon like "synergistic liability" and "fourth-quarter profits" in place of insults or vulgarism. J is also arrogant, domineering, and prideful, as she finds satisfaction in belittling others. This habit often tends to get the better of her. Since J is a Disassembly Drone she must consume oil in order to not overheat. She also has access to retractable blade like wings, claws, and fangs in order to most effectively kill Worker Drones.
