King Kong (キングコング Kingu Kongu) is a giant ape kaiju who appeared in the 1967 Toho film, King Kong Escapes. He is the second incarnation of the character to appear in a film produced by Toho. A legendary giant ape said to inhabit Mondo Island in the Java Sea, Kong was the subject of a great deal of research by Carl Nelson, who was hired to develop schematics for a giant robot based on the ape monster. Nelson resigned over concerns that his research would be used to create a weapon and went on to work for the United Nations, while his former colleague Dr. Who stole his blueprints and used him to create his own personal weapon designed to mine the highly radioactive Element X: Mechani-Kong. While on a research mission aboard the UN submarine Explorer, Nelson and his comrades Jiro Nomura and Susan Watson made a stop on Mondo Island where they witnesses Kong emerge to defend Susan from the giant dinosaur Gorosaurus. Kong tried to pursue Susan back to the Explorer, but was attacked by a Giant Sea Serpent. After defeating the creature, Kong grabbed the Explorer only standing down after being convinced by Susan. Upon learning that Nelson had discovered Kong and following the failure of his robot, Dr. Who and his men kidnapped Kong from Mondo and brought him to their Arctic base, along with Nelson and his allies. Who's plan to control Kong and force him to mine Element X failed and the beast escaped. Dr. Who pursued Kong to Tokyo, and unleashed Mechani-Kong into the city to subdue him. Mechani-Kong grabbed Susan and held her hostage as it scaled the Tokyo Tower with Kong in pursuit. Kong was able to catch Susan as his robot double dropped her, while Dr. Who's business partner Madame Piranha turned on him and destroyed the robot's controls, causing it to fall to its destruction. Kong then hunted down Who's ship and destroyed it, killing the mad scientist. Kong then began to swim back to his home on Mondo Island, with his human friends bidding him farewell and thanking him for what he had done.
