King Kong first appeared on Farou Island, and he was worshiped by the natives as a god. A TV station, called TTV, wanted the monster to get their rating up. They went to the mountains to look for Kong, but they only heard him. Later that night, a Giant Octopus attacked the village, and Kong came to fight it. He managed to drive the octopus away, and the natives helped put him to sleep. He was transported to Japan, but he broke loose of his chains and swam towards the shores. He met Godzilla on the mainland, and tried to fight him. The fight did not last long, because one shot from Godzilla's nuclear breath sent him running. King Kong later attacked Tokyo, and destroyed most of it. A special chemical was poured on Kong, and the native's song put him to sleep again. The military attached balloons to King Kong to transport him to Godzilla so that the military could destroy the both at the same time. The two monsters fought, but Godzilla was more powerful. Had threw Kong on the ground, but he harnessed the power of lightning. Kong and Godzilla fought on the side of Mt. Fuji, eventually tumbling off it and into the ocean. Kong emerged victorious, and swam back to Farou Island.
(ゴリラ?) due to the rights of the character for use by Toho being lost, also appears in episode 38 of the series Go! Greenman titled Greenman vs. Gorilla. In the episode, Gorilla was a creation of GoriraCretin, created for the sole purpose of retrieving the blood of children in order for Maoh to escape the Underworld. The King Kong suit is from 1967's King Kong Escapes. In the series, he was the thirty-ninth monster to battle Greenman.
In both of his Toho incarnations, King Kong is a extremely capable melee combatant, using his large arms, powerful muscles, and mighty fists to strike fear in foes such as the Gorosaurus, the Giant Octopus, and even Godzilla himself. In his first incarnation in King Kong vs. Godzilla, the mighty primate cannot be harmed by electrical currents, and instead, feeds on their power in order to revitalize or awaken him from a state of unconsciousness. He can also use those same electrical currents, whether they are man-made or natural, to allow him to release surges of electricity from his hands, a powerful tool against Godzilla. The second incarnation of the Toho Kong who appeared in King Kong Escapes lacked these abilities but instead was immune to the radioactive Element X.
King Kong appears to be particularly resistant to Godzilla's atomic breath. He is hit by it multiple times throughout the King Kong vs. Godzilla, and usually suffers little more than having some of his fur singed.
