Feature Comics #48 (1941)

Doctor and Martha Roberts fly off to South America, just as some serious Nazi trouble is brewing up down there, and Darrel Dane gets to the airport too late to stop them. He visits the zoo, breaks into an eagle's cage, gets small, steals the eagle, guides it in flight, and overtakes the Roberts's airliner just as it is unexpectedly landing on [https://en.wikipedia.org/wiki/Devil%27s_Island Devil's Island], off the coast of French Guiana in South America. Unable to persuade the eagle to land, Darrel skydives to the island, using two feathers for a parachute. -- On the island, Martha and Doctor Roberts (who seem to be the airliner's only passengers) meet the island's swinish new boss, Ernst Huller of Aryania (in a gray military uniform), who orders his underling Hermann to take them out and kill them. They are marched to the edge of a tall cliff by Hermann and one other creep; then Doll Man shows up and beats down these punks. Doll Man's tactics are distinctly more vicious, and his attitude is much less jolly, during this fight, than has been the norm in earlier episodes; he convincingly threatens to poke out one guy's eye with a big thorn. -- Back at his HQ, Huller belatedly learns that the well-known Doctor Roberts is in his power, and sends his aide to abort the execution and bring back the prisoners and guards; Doll Man hides in Martha's hair and accompanies them; one guard insists that he really did see a tiny man but the aide rudely disbelieves him. Back at the HQ, Huller wants Doctor Roberts to mark some defense plant locations on a big wall map, and has his thugs stick Martha into a large, modified, manual printing press, to enforce compliance. Unseen by the bad guys, Doll Man gets between the plates and lifts until the press is broken, then before the Nazis can even check out the problem with a quick look into the press, they are interrupted: Huller has just now learned that The Leader is arriving at any moment, so the prisoners get whisked away to the dungeon while everybody else leaves for the airfield, leaving Doll Man alone with their radiotelephone. "He flips a lever that is marked 'invasion fleet communications'," then gives misleading spurious orders to the invasion air fleet, and tricks them into landing on a fetid bog. (Two single-engine fighters are visible, but dialogue indicates larger and more aircraft must be arriving with them). -- At the crash site, Huller and at least four of his soldiers arrive, and are ambushed and punched out by Doll Man, who then returns to their HQ and again commandeers their radio, to call the U.S. airdrome, off Trinidad, to send some bombers over to Devil's Island. Outside the building, Huller has revived and caught up and knows Doll Man is inside; his next move is to burn down his own HQ in order to get at the tiny superhero. Inside the building, Doll Man searches until he finds his friends in the dungeon, and he rips apart the iron bars of their cell "like matchsticks." They still can't get out of the house, which is ringed by brushfires, but just then a U.S. 2-engine bomber zooms in and drops two bombs, one of which lands just close enough to snuff the fire on that side of the building but not close enough to smash our three heroes, who then escape from the burning house. Doll Man pursues Huller and punches him out again. U.S.Marines land and convey the Robertses back to U.S. territory, while Doll Man hitches a ride back home aboard a seagull.
