J's upper head is a black screen that displays 2 yellow neon eyes and white silverish hair in twin tails tied with black ribbons. Like other Disassembly Drones, she has a black headband, with five sections of lights and a long presumed to be her "real eyes", and a thin black tail ending in a large syringe, both containing a neon yellow liquid, presumably nanite acid. Her skin is a pure white short-sleeved dress with a belt sideways as well as strap buttons and pockets on the side with a bowie.
