a bald detective with pebble glasses and a long nose who usually wears a black frock coat. He is always fighting with Phil, his partner, mostly because he tends to mess things up, usually to Phil's discomfort: his profound lack of skills to make his disguises believable and common sense have often made him a danger to everyone around him. His favourite hobby is wearing all sorts of (sometimes outrageous) disguises - professional and historical clothes and gear, animals, inanimate objects, even small-sized vehicles like miniature blimps and mopeds - which he mostly dons for special tasks or when he is on the run from Phil or his boss, and which all include his signature collar which obscures part of his mouth.
