Nat Natnus, also known as Nat the Fur King, was a fur thief and seller. He had light eyes, light hair and a moustache. Dick Tracy first encountered Nat during a minor traffic infraction. Nat's car led Tracy on a brief chase, forcing Nat and his gang to abandoned some furs that he had recently stolen. Finding the stolen furs piqued Tracy's interest, and he began an investigation into Nat's activities.
