The Boy King was an exile from the Nazi-threatened land of Swisslakia who came to America to gather support and aid America in the fight against Hitler. Boy King fought spies and saboteurs that threatened America’s security, using his wits, royal fortune and a skyscraper-sized Golem that only he could command. Strangely, the Boy King and American officials never considered using the Golem to step on and squish all the Nazis. Hitler and his cronies were not so innocent though and considered the Golem a potent obstacle in their goal of conquering the world. In order to defeat the Boy King and his statue the German High Command orders the construction of a similarly-sized weapon that would attack and defeat the Boy King before moving on to crush all American resistance. What they came up with was the obvious response: a Giant Nazi Dinosaur Robot.
In the Golden Age there was a whole lot of pulse-pounding content jam-packed in about 30 pages of art and story. In those days, decompression meant that was what the artist did in a bar after a long day of trying to get paid by a cheap publisher. There is plenty of non-stop action in this story. In Clue Comics #4 and #5, the heroic Boy King defends American shores from a giant robot, battles his arch-nemesis (a Nazi officer with extending prosthetics for hands who comes off kind of like one of the Robonic Stooges) not once but several times, fights an octopus, meets a cute girl and there is even a slow-moving death trap thrown in for good measure!
Be prepared to freak out.
