Deckerd was the first robot programmed with Super A.I., which was intended to make him a semi-interactive police officer. However, after six months of contact with Yuuta Tomonaga he became sentient. All of the later sentient robots' Super A.I. were copied from Deckerd's. He usually keeps a serious demeanor as the leader of the Brave Police robots and acts as a peace keeper during conflicts within the team. His closest loyalty lies with Yuuta. He transforms into a police car.

Grade schooler Yuuta Tominaga stumbles upon Deckerd, a humanoid robot under construction by the Japanese police, built to fight advanced forms of crime. Yuuta's constant contact with Deckerd gives the robot a "heart", or personality; when Yuuta is recruited as the "boss" of the "Brave Police" as a result, a true human/robot partnership occurs. <br><br>
