This time, it is foes of Vigilante, Doctor Fate, Hawkman, Green Lantern and Kid Eternity....all from the Golden Age, with villains of the Dummy, Nyarl-Amen, the Human Fly Bandits, Solomon Grundy and Master Man.
The Little Men Who Were There
The Dummy was a small man, with a big evil intellect, who after finishing a train robbery, sent a message to Vigilante about his next robbery....he was going to heist a flying plane!
The Dummy was the only villain from the third issue who appeared outside the tale reprinted, featuring in issues of Leading Comics with the Seven Soldiers of Victory, as well as facing Vigilante in other issues of Action Comics (sadly no other Vigilante/Dummy stories were reprinted).
The Fish-Men Of Nyarl-Amen
Here, the Doctor faced the ancient foe of Nyarl-Amen!
The Human Fly Bandits
The flying duo faced The Human Fly Bandits!
Fighters Never Quit
Cyrus Gold was an old thief who died in Slaughter Swamp 50 years before this story. Escaping hoods wandering the depths of Slaughter Swamp outside of Gotham found a reanimating corpse...who could articulate enough to say he was born on Monday (which gave them the idea to name him Solomon Grundy).
Only this and Grundy's JSA appearance from the Golden Age have been reprinted, but his Silver Age appearances (against Dr. Fate and Hourman, and two battles against the JLA and JSA have been). Grundy would soon become very popular, facing Superman in his title and becoming a member of the Legion of Doom on the Super Friends cartoon.
....featuring the debut of Master Man, evil foe of Kid Eternity and his helper, Mr. Keeper!
As Kid Eternity could summon dead heroes to help him by saying "Eternity", Master Man was empowered by the devil to bring up dead villains for more dastardly deeds by saying "Stygia".
Master Man would later return with other Satanically influenced villains to face the Marvel Family and Kid Eternity in two digest issues of Adventure Comics (the Marvel Family's last solo tales before the Crisis On Infinite Earths).
Vigilante and Kid Eternity would have their Secret Origins featured in a soon to debut new reprint title that he edited, and the Hawkman and Dr. Fate stories were more for the heroes (though Green Lantern was a big thing). The letters' pages promised if there was enough demand, new stories would be possible, but later issues didn't prove that out (but, unlike the first two issues, these were all Golden Age stories!).
