Murder Terror Drones

This is Uzi, she's the protagonist in this horror story. Uzi is characterized as a rebellious "Worker Drone" with purple hair who often wears a black beanie, but in this alternate universe she feels carefree, anxious, and innocent. Sometimes she's afraid to sleep alone because she's afraid of the Disassembly drones. She feels sadness, pain, and suffering for her society of worker drones. She even has panic attacks. Sometimes she can become gloomy.

Now things are changing in this horror story. The Disassembly Drones, also known as "Disassembly Drones," appear to have visors always in "><" shapes, metallic wings with bloodstains, and they possess chainsaws and hacksaws with sharp, lion-like teeth. They behave like demonic beasts.

After the Germans created this, they were also killed.

Originally, they were created by the megacorporation JCJenson (in spaaaaace!) to serve as an autonomous workforce. Their function was to mine resources and maintain facilities on exoplanets like Copper 9, which belonged to the Germans.
Everything changed when humans accidentally caused the planet's core to collapse, extinguishing all biological life there. Freed from their human masters, the Worker Drones:
They developed their own consciousness and personalities.
They built their own society, with schools, families, and jobs.
They began living in "bunkers" to protect themselves from the eternal winter and external threats.
Appearance: They have screens in place of faces that display digital eyes and emotions. They usually wear discarded human clothing.
Robotics Biology: They run on oil, which serves as their "blood." Unlike their predators, they don't need to consume oil from other drones to survive, unless something changes in their code (like the Absolute Solver).
Vulnerability: They lack integrated weapons and are physically fragile, making them easy prey for Murder Drones.
