|Voice actor||Maxwell Atoms|
He is a pony-tailed half-Goth, beatnik, and Bohemian child who wears all-black clothes, fashionable sunglasses, a jaunty beret and a distinguishing belt buckle that says "HATE".
He is usually silent, and expresses himself only through his imperious attitude, the occasional raised eyebrow and how he applies his saliva to the situation. His real name is never revealed; "Piff" is the name given to him by Billy when Irwin pointed out that they have to call him by some name, when he does finally talk, he speaks in a very high pitched voice.
