* EthnicScrappy: Joe Jitsu and Go-Go Gomez are drawn with exaggerated stereotypical features. Gomez could move very fast, although he did so with lots of "Arriba! Arriba! Yeeha! Yeeha!" yells that turned him into a human Speedy Gonzales. (Mel Blanc actually voiced Gomez in the Mr. Magoo cartoons in which he appeared.)
* FairForItsDay:
** Joe and Gomez may be ethnic stereotypes, but they're also intelligent and capable heroes, as opposed to Hemlock and Heap, who tend to solve their cases through dumb luck more than anything else.
** Executive producer Henry Saperstein would comment that Joe Jitsu was created as a good guy to help soothe any ill feeling to the Japanese after the end of World War II. It was impressive to have a Japanese good guy, even a stereotypical one, once you realize this wasn't too long after Pearl Harbor and World War II.
* SoBadItsGood: It was standard low-budget fare for kids' TV programming, but it was often so cockeyed one couldn't help but laugh. Even with Everett Sloane's earnest voicing of Tracy.
