* EarWorm: That big band theme is as catchy today as it was in 1964.
* EnsembleDarkhorse: Jade, who only appears in two episodes, became very popular precisely because of how little we knew about her. She also offers a tantalizing glimpse at Race's past.
* EthnicScrappy: Charlie, the Chinese cook in "The Sea Haunt", comes uncomfortably close.
* FairForItsDay: Nearly all the characters from more "exotic" countries - including villains - are little more than ethnic stereotypes of varying degrees by today's standards. This includes one of the ''main characters'', Hadji (though, despite this, Hadji was treated as an equal by Johnny, Race Bannon, and Dr. Quest). This leads to UnfortunateImplications in the case of some of the Asian villains, who clearly show shades of YellowPeril in their characterization.
** Speaking specifically of Dr. Zin, he is very much one of the trope codifiers for the Yellow Peril stereotype. In later productions Zin still maintains these elements but also is allowed to be a bit more funny than he was in the original series. Even still in 2015 his appearance in Spy Quest is very similar to how he was depicted in the 80s and 90s. Despite uproar over another Yellow Peril characters marketability, Dr Zin seems to have not caused any detectable ruckus.
* FirstInstallmentWins: The remakes and sequel series are generally not as favored as this original series.
* {{Narm}}: One episode features an Indian chief who is ''very'' obviously voiced by the same actor as Race, to the point that it's genuinely surprising it never turns out he's Race in disguise.
* [[ValuesDissonance/WesternAnimation Values Dissonance]]: Multiple TOS episodes are, these days, considered racist and sexist
* [[WhatDoYouMeanItsForKids/WesternAnimation What Do You Mean It's For Kids?]]: This for it's day was one of Hanna Barbera's major steps into the action genre. While marketing wise this show aired in primetime, so it's plan was more likely to be engaging enough adults would want to watch but still nice enough for the kids to watch too. As a result this show was easily able to survive on Saturday Morning for decades. While today some might wonder why a show with some of the FairForItsDay material is seen as a "kids" show. But then again sometimes marketing is not in the prowess of some of these such conversations.
