I remember this show. Tho I was 15, I always enjoyed cartoons, still do today. I was scoffing at it then, and, as usual, now I do find some aspects enjoyable about it (mainly Rex Ruthless, who I liked then and now).
As others note, this is NOT the Shazam segments, tho they all aired together in the same program 30 years ago. This clearly was supposed to be the comedy heroes compared to Shazam (Captain Marvel) who was the 'serious' hero (fighting Sivana and a caterpillar?)
I guess now the interesting part to me is that this was proposed as superhero Archies and that deal fell thru. Yes, the show and characters are clearly set up as the Riverdale gang (can't quite picture Veronica as Dirty Trixie. Jughead as Punk Rock?)
Another aspect I have always pondered over the years was how none of the performers went on to other programs. Maylo McCaslin, who was Trixie, married Willie Aames of 8 is Enough, but I'm really surprised none of them were drawn into soap operas, especially the two blondes.
I guess what always intrigued me, even as a teen, was the live performers clearly enjoyed doing the corny jokes and songs, so they were devoted to the program (always a plus)
