This mecha paper model is the Mechani-Kong's head, based on the film The Revenge of King Kong of the King Kong series, the papercraft is created by godzillu. Mechani-Kong is a remote-controlled robot double of King Kong introduced in the 1966 animated television series The King Kong Show and featured again in the 1967 film King Kong Escapes. The robot was created by Dr. Hu to kill the giant ape King Kong.
Mechani-Kong was built by Dr. Hu to dig for Element X, a large core containing a natural abundance of nuclear power. However Mechani-Kong was not strong enough to dig out the element, as the robot's circuits were destroyed by magnetic waves. Dr. Hu then kidnaps the real Kong to dig for the element, placing him in a hypnotic trance. Kong eventually breaks out of his trance and swims to Tokyo, where he and Mechani-Kong fight atop Tokyo Tower. After a long battle, in which both of them nearly fall off the tower, Dr. Hu's associate Madame X rips out the robot's control cords, causing Mechani-Kong to malfunction. The robot falls to its destruction from the top of the tower, mirroring Kong's demise in the original film.
Aside from its great strength, Mechani-Kong possesses a dome on the top of its head which features a flashing light that can be used to blind or hypnotize its foes. Although not as agile as the real Kong, Mechani-Kong possesses greater endurance. It is later modified with attachments on its waist which it uses to carry multiple grenade-like explosives. He can also fire beams from his eyes.
