Though Blue Beetle is not explained as having superpowers until next issue, he may display them here for the first time when he defeats 20 mobsters in one fistfight, when previously he could take two or three mobsters at a time.

This is the last appearance for this character, who is called "Moth Man" on the cover. The plot of this story just had to have been taken from Mary Shelley's novel, "Frankenstein." NOTE: The strip carries the by-line of "Norman Kingsley", which may have been an editorial alteration of the by-line "Norton Kingsley", which was the pen-name of Chuck A. Winter, who drew The Lynx for Fox in 1941. The editors may have just stuck this by-line on the strip [not unusual in those days]. The Men of Mystery reprint ID's Pierce Rice with the art, but Rice only penciled the strip circa 1941, while Mooney did full art from 1940 into 1941. This information added by Craig Delich 2010-6-1.
