Robot (45–50 Earth years old). Mechanic at St. Isaac’s Hospital. Invents various gadgets and devices in his spare time. Archie has wheels instead of legs. These help him get around very quickly, but given that he’s so scatterbrained and clumsy, they don’t always take him in the right direction. Archie’s hospital scrubs are labeled with the character 痴 (pronounced “chi” in Chinese, a reference to his name, Archie), which means crazy or passionately carried away.
