Deckerd is the first of the Brave Police robots to be built, equipped with the powerful Super-AI that allows him to have a conscience. He was originally meant to be a normal robot with a handler only, but his first experiences with Yuuta Tomonaga caused him to develop a "heart" and gain human emotions, along with making his combat capabilities far exceeding original specifications. He has an honest and sincere personality and acts as the robot leader of the Brave Police.
