- Shout-Out: The Powerpuff Girls gave a huge one to this show with Mojo Jojo.
- U.S. version: The English-dubbed adaptation of Spectreman was produced and aired in the U.S. in 1978, a full 7 years after the original Japanese version. (Compare to the two years it took for Mighty Morphin' Power Rangers to be created from Zyuranger.) As such, the dubbed Spectreman has multiple unintentional anachronisms where early Seventies cars, hair, and fashion stand out. This adaptation featured a brand new "Spectreman" opening theme song with prominent use of synthesizer, which would not have been TV theme instrumentation in 1971. Also, to contemporary audiences of 1978 the costumed Spectreman would have somewhat resembled a lame knock-off of C-3PO from Star Wars, a 1977 release.
