“I hold supreme power of life and death... Surrender, Zarkon—or die!”

Knickerbocker City was paralyzed with fear. Two banks had been disintegrated by fiendishly targeted earthquakes. And the latest message from Lucifer, arch-villain and criminal mastermind, who had escaped from prison with his nefarious henchmen, was clearly a challenge to the city’s last hope of rescue, Prince Zarkon and his Omega Men. But what good are their atomic submarines, scanner probes, and fantastical, foe-flattening firearms if they can’t locate the malignant genius behind the plot? It is a dark hour for Knickerbocker and all mankind.

This is Prince Zarkon adventure #4. Zarkon is a man of mystery, a superhero who fights crime everywhere.
