Serial Designation J-10X111001, or simply known as J, is the one of the two secondary antagonists alongside Doll in Murder Drones. J is a former Worker Drone, converted by Cyn into a Disassembly Drone and sent to Copper 9 to destroy the runaway AI as Worker Drones. Her colleague N teams up with the rebellious Worker Drone Uzi who wants to rebel against the company and humanity.J has the features of a typical female Disassembly Drone. She has neon yellow eyes and silver hair in twin pigtails tied with black ribbons. Like other Disassembly Drones, she wears a black headband adorned with her five real eyes. She also has a thin black tail ending in a large syringe containing Nanite Acid as all Disassembly Drones have. She appears to be wearing a black short-sleeved dress with pockets on the side and a black leather belt and a black tie with dark yellow collared shirt. She also wears knee-high stockings with visible suspenders. Like other Disassembly Drones, she dons a yellow armband around her left bicep. When hunting for Worker Drones, she reveals her jagged teeth while her visor displays an "X" shape with large bladed-sharp wings and sharp claws that allow her to easily tear and kill her targets.J is best described as a "lethal workaholic", as she is incredibly dedicated to her job. She also uses corporate jargon like "synergistic liability" and "fourth quarter profits" as insults or vulgarism. Although J is not as sadistic and insane as V is, she does look down on others who are not as good as her. This is best shown in J's relationship with N, as she despises him and tells him that she would personally kill him if their company allowed it. J's dislike of N goes as far as to infect him with a virus as soon as he starts to question the company even though there was a valid reason for doing so while also taking glee in doing such an act. J is also arrogant and prideful, as she enjoys insulting
