Mechani-Kong is the creation of the villainous Dr. Who, a mad scientist bent on world domination and the sworn enemy of King Kong. In The King Kong Show and its tie-in media, Mechani-Kong is frequently deployed by Dr. Who to destroy Kong or menace his human allies. In King Kong Escapes, Mechani-Kong was instead built by Dr. Who for the purpose of mining the highly radioactive Element X. When the radiation damaged the machine, Who resorted to kidnapping the real Kong from his home of Mondo Island to force him to dig for the element instead. However, Kong was able to resist the madman's mind control and escaped Who's Arctic base. Dr. Who repaired Mechani-Kong and sent it to Tokyo to capture Kong in order to make him continue his task. After a pitched battle atop the Tokyo Tower, Kong defeated his robot double and sent the machine plummeting to its doom on the streets below. Toho planned to revive Mechani-Kong for several Godzilla film projects in the Heisei series, but legal concerns regarding the use of the character caused these films to be scrapped. Nonetheless, the robot appeared in The Godzilla Comic and Kodansha's Godzilla, King of the Monsters manga in the early 1990s.
