Nurse Ratchet is a robot nurse who works at the Hal Institute for Criminally Insane Robots. She has a kind personality, but is forceful in her work, utilizing the net-like strait-jacket which she is able to shoot from a compartment in her chest.
- Nurse Ratchet is a reference to Nurse Ratched from the book and film, One Flew Over the Cuckoo's Nest. Nurse Ratchet even looks like a robotic version of regular Nurse Ratched.
