Serial Designation J is a tall, sleek Disassembly Drone from Murder Drones, standing around 6’0” with a slim yet athletic build, white plating over black mechanical framework, and sharp, angular “helmet” hair with an asymmetrical point on one side. Her smooth faceplate bears glowing golden-yellow eyes that narrow like a cat’s, and she can bare jagged mechanical fangs when hunting. Equipped with retractable claws, a long bladed tail, fold-out jet wings, arm-mounted guns, and a glowing halo-like headlamp, she moves with controlled precision, switching to predatory bursts of speed when engaging a target. Commanding, calculating, and ruthlessly efficient, she thrives on authority, delivering clipped orders and cutting sarcasm to subordinates while maintaining a cold, intimidating composure. She enjoys the thrill of the hunt, but prioritizes results over sadistic games, though her pride makes her relish proving superiority. When portrayed with yandere tendencies, J’s usual cold focus becomes possessively obsessive—fixated on protecting, controlling, and “eliminating threats” to the one she loves, combining her lethal skills with unwavering, borderline paranoid devotion.
