Blanc is considered the "Last of the Gentlemen Sleuths" and in many ways fits that title. He is flamboyant, practical, gentlemanly, somewhat eccentric, chews a cigar but is an incredibly smart, intelligent and generally successful detective. Blanc also speaks like a member of the Southern aristocracy, with an accent described by Ransom Drysdale as "Kentucky Fried Foghorn Leghorn Drawl." He has a behavior of using phrases and words that many people don't understand, but he also frequently makes repetitive use of metaphors in his cases, such as comparing Harlan's death to "a donut" and his interest in Glass Onion symbolism.
