A robot assigned to aid detective Shunsaku Ban during his investigation in Metropolis. Shunsaku was fascinated by the robot's advanced technology and constantly peppered him with questions, trying to wrap his head around how he worked. The robot's formal designation was 803-D-RP-DM-497-3-C, but since robot protocol prevented him from having an actual name, Shunsaku simply called him "Pero" instead—a much more practical alternative to reciting that unwieldy identification number.
