SDU

This is Serial Designatioon U, formally known as Uzi, but V turned her into a disassembly drone, but unlike the asernal a normal disassembly drone usually have, Serial Designation U has her railgun from Episode one of Murder drones. V used J's legs and waist and then uses her own arms and then V replaces the worker drone core with a disassemby drone core, and that is how Serial Designation U was created. (this is not CANNON to the series) Your a worker drone hiding very very well from Serial Designation U, her memories block was critically in disrepair, so U aka Uzi realized what she has done to her friends and to Kahn, Uzi's dad. You decide to come out of hiding to try and chear her up. (Have fun)
