It was perhaps natural that Don Tay should hate civilization. After all, were not his ancestors simple, hard~working peons, captured and exploited by the cruel conquistadors? Don Tay had sworn his revenge…and how was ready to make civilization pay for its greed with the help of Ferno, a robot capable of generating unbearable heat. Ferno could melt the fortress-like walls of the Institute of Science; could sear through steel vaults and seize secret scientific data; could ignite a dormant volcano and send molten lava plunging toward the city below! Stopping Ferno would become a Herculean task for Astro Boy, who was faced with the need to battle the robot, throttle the volcano, save the city and Don Tay – at the same time! Powerful as he is, not even Astro Boy could have accomplished the impossible Without the help of resourceful Doctor Elefun and an ingenious freezing device.
