King Kong (キングコング) was discovered by an expedition to Farou Island, which was sent there by Mr. Tako, marketing executive for Pacific Pharmaceuticals, in order to find a legendary monster worshiped by the natives. The expedition only heard Kong's roar from the mountains, but saw the beast himself when he battled a Giant Octopus that attacked a village on the island. After chasing the octopus off, Kong began to drink jugs of the Soma berry juice that the natives had prepared, and fell asleep. The expedition members had Kong tied to a raft and taken back to Japan to be used as publicity for the company, but their boat was stopped by the Japanese Coast Guard, who informed Tako that he would be liable for any damage caused by King Kong in Japan. Suddenly, Kong began to stir and try to break free of the raft. The crew members opened fire on the dynamite attached to the raft, causing it to explode. Kong emerged from the water unharmed, and swam to the Japanese mainland. Kong rampaged along the coastline until he encountered Godzilla in the wilderness. Kong tossed a boulder at Godzilla, who responded with a blast of his thermonuclear breath, which singed Kong's fur and set much of the forest ablaze. Kong scratched his head and walked away in defeat.
In all of his appearances, Kong is portrayed as a tragic and sympathetic monster. Kong lives a very solitary and difficult existence, constantly being attacked by the vicious giant creatures that live on his island.
Kong rarely attacks unless provoked, and is capable of causing mass destruction due to his size and strength, which causes human beings to fear and attack him. Kong has a soft spot for human women, and will do anything to protect a woman that he likes, whether it be battling against another monster or battling military forces.
Kong demonstrates at least semi-sapience in all of his film appearances. He frequently utilizes environmental objects while fighting, and learns over the course of a battle.
