Inspector Detector

Inspector Detector (六郷警部, Rokugō-keibu, "Detective Rokugo") is a recurring character in Speed Racer's adventures.

Character traits
Inspector Detector is always doing whatever is necessary to bring about justice. He is an affable person and is always willing to thank and reward those who help him solve crimes.

He also seems at times to be working in cooperation with Racer X, who is a secret agent (Agent 9) with Interpol. It is not clear if they actually work for the same organization. Inspector Detector also seems to know about Racer X's real identity as Rex Racer, though again it is unclear if this knowledge is mutually shared through the relationship or whether the Inspector has seen a dossier on Racer X.

Differences
In the original series, Inspector Detector was a senior law enforcement officer with the local police. In the movie, his role was investigating corporate crimes for the CIB, and he was a "handler" of sorts for Racer X.

Relationships
Inspector Detector is a good friend of the Racer family, especially Speed.

Behind the scenes
A similar character appears in the 1969 Tatsunoko series Kurenai Sanshiro (released in certain territories as Judo Boy).
