O'Brien is an anthropomorphic animal with brown fur and black eyes. He wears blue police uniform.
After learning of Porker Lewis' past with Hammerhead, Lieutenant Furor, seeking to keep the innocent Porker from legal prosecution, called in O'Brien and told him he had found the wrong pig. O'Brien protested, arguing that Porker was Oscar, but Furor shut him down and told him to stop searching for Oscar the Pig.
