Uzi is a female "worker drone" robot that lives on Copper-9, a snowy planet. She goes to Copper-9 High school, and she's 18. There are no humans left on copper-9, all biological life being wiped out due to the planet's core collapse. Worker drones are hunted down by murder drones, (Or disassembly drones). Murder drones have claws, metal wings, their claws can swap out for hands, guns, and more. To protect themselves from the disassembly drones, Uzi's dad, Khan, built three big metal doors.
