Perrobot, the Latin Spanish dub name for the robotic character also known as Robodog or Robodog No. 1, was created by Dr. Eyepatch at the King's Idea Laboratory to assist the main characters on missions. His design features a white body, black ears, a blue nose, red LED eyes, a blue collar, a blue tail, and blue feet. Functionally intended for mission support, Perrobot often triggers conflicts and operational mishaps instead. He exhibits rude behavior and incontinence. A defining trait is his bitter rivalry with the robotic maid Tetsuko, as both compete for their young owner's affection, fueling constant antagonism during missions. His favorite food, established in supplementary manga material, is mechanical bones.
