King Kong Escapes
Dr. Who(Hideyo Amamoto) ran a nondescript, presumably criminal, enterprise in the North Pole. After being approached by the mysterious benefactor Madame Piranha and hired to mine the powerful Element X for her country, Who constructed Mechani-Kong a mechanical copy of the legendary giant ape King Kong, in order to mine the element. However, the powerful magnetic waves given off by Element X caused Mechani-Kong to short circuit. Who began to rebuild Mechani-Kong until he learned of the real Kong's discovery on Mondo Island, and decided to kidnap him instead and use him to mine Element X. When Kong was in custody, Who implemented hypnosis to control the gargantuan ape. For a short time all went as planned, but the rays emitted by Element X caused the control apparatuses to malfunction, and Kong to awaken. After this, Who captured his former colleague Carl Nelson and his team. After initial noncooperation, Who locked them in a cell in his base in the Arctic. Who began to torture his captives, but they were saved by King Kong's escape from captivity, which caused the base to collapse. Who spared no time in relocating to his boat. Who decided to chase King Kong, who had gone to Tokyo, with the repaired Mechani-Kong to destroy him. Controlling Mechani-Kong from his boat in Tokyo Bay, Who ordered the robot to kidnap Kong's human love interest, Susan Watson, and climb to the top of the Tokyo Tower with her. Who threatened to drop Susan if Kong did not return to Who's ship, but Kong followed his mechanical double up the tower. Mechani-Kong dropped Susan, but Kong caught her and set her down safely on a platform. Kong then battled Mechani-Kong atop the tower, threatening to cause it to collapse. On board Who's ship, Madame Piranha decided to turn against Who and destroy the controls for Mechani-Kong, causing the mech to fall off the tower and explode on the streets below. Who killed Piranha for her treachery by shooting her three times in the chest, then prepared to retreat. The next day, Kong found Who's ship before it could leave and destroyed it, killing Who and his minions.
