Mechani-Kong (メカニコング,   Mekanikongu?), also known as Robot Kong (ロボットコング,   Robottokongu?), is a robotic version of King Kong created by Rankin/Bass Productions and Toho that first appeared in the 1966 animated series The King Kong Show, and later appeared in the 1967 Toho film, King Kong Escapes.


Mechani-Kong's name comes from the word "mechanical" and the "Kong" part of King Kong's name. In the Japanese version of The King Kong Show, he was referred to as "Robot Kong" (ロボットコング,   Robottokongu?).

Mechani-Kong in King Kong Escapes

Mechani-Kong was both designed and built by the international criminal, Dr. Hu, to mine the radioactive Element X from the Arctic underground, but the robotic ape failed his creator, the radiation of Element X damaging his controls. However, Dr. Hu came up with another plan to abduct the real King Kong and using Mechani-Kong, hypnotize Kong to mine Element X instead. However, the combination of Kong’s mind and the cries of Nurse Susan Watson, who Kong had a liking for, were able to overcome the hypnotism and Kong escaped to Tokyo, with both Mechani-Kong and Dr. Hu in hot pursuit.

In Tokyo, King Kong and Mechani-Kong battled up the side of Tokyo Tower, both monsters getting their shots in on one another. In the end, an attack back on Dr. Hu's ship crippled Mechani-Kong's controls and turned the tide of battle in Kong's favor. The crippled Mechani-Kong then fell from the tower, crashing into the street below and shattering into several pieces.

A second Mechani-Kong was built and teamed up with MechaGodzilla III under the control of Doctor Oniyama to fight Godzilla in the Kodansya Godzilla manga, but both failed. Godzilla suplexed Mechani-Kong, breaking his right arm in the process. Powerless, the mechanical ape fell on top of MechaGodzilla III, and sank into the ocean. He was presumably deactivated by his internal systems short-circuiting.
