I always thought "The Guardians" felt much more like The Outer Limits than TZ, but Dell had the rights to the former show, so we got it as a TZ entry, albeit reassigned to TOM. There must be an interesting story behind that.
At any rate, the story is wonderfully illogical, with the intrepid reporter instantly recognizing the three brain-zapped scientists now wandering the alleys as bums ("Of course! Dr. Stroller, the Nobel Prize winner in biochemistry!"). Highly fun, and with plenty of space (twelve pages) in which to tell it. Here's the cover, title page, and two sample panels:
The Grand Comics Database credits pencils and inks to Sal Trapani, but the pencils sure look like Bill Molno to me. This is one of those instances in which my level of certainty is complete. Below I've positioned "Guardian" panels above and/or next to Charlton Molno panels, to hopefully demonstrate that we're looking at the same penciller:

At the moment, I'm looking at three other Tales of Mystery stories that I suspect to be Molno/Trapani combos. Stay tuned!
