In all of his appearances, Kong mostly resembles a giant silverback gorilla, with either light black or brown fur. Kong varies between knuckle-walking like a real gorilla and walking bipedally and upright like a human, sometimes utilizing both forms of locomotion in the same film.
In the 1976 remake, King Kong's vocalizations were provided by an uncredited Peter Cullen. These roars would go on to become very famous stock roars and were even used for Toto in Gamera: The Brave 30 years later.
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.
In the 1976 remake, and King Kong Lives, Kong is among the last living members of a giant species of ape that lives on the mysterious Skull Island, which is inhabited by other giant creatures as well as a tribe of natives that worship him as a god.
In the early 1970s, Universal Pictures, who owned King Kong's copyright in the United States, planned to produce a remake of the 1933 film entitled The Legend of King Kong. However, Dino De Laurentiis and Paramount Pictures purchased the film rights to King Kong from RKO and produced a remake instead. Paramount's 1976 remake was a modest success, and ten years later De Laurentiis Entertainment Group produced a sequel entitled King Kong Lives, which received very negative reviews.
Kong took Dwan to a waterfall and washed her underneath it, then blew on her to dry her. Dwan was surprised at how gentle Kong actually was, and began to no longer fear him. Meanwhile, Jack Prescott, a primate paleontologist who had stowed away onto the expedition's ship earlier, joined with several members of the crew to look for Kong. En route, they reached a giant fallen log that acted as a bridge over a deep chasm. Kong spotted the men as they crossed the log bridge and grabbed the bridge, twisting it until all of the men except Prescott and another named Boan fell to their deaths. Prescott decided to continue pursuing Kong on his own, and headed deeper into the jungle. Kong took Dwan to his lair and prepared to undress her, but found himself attacked by a gigantic boa constrictor. Kong set Dwan down and battled the snake, just as Prescott caught up and found Dwan. The two escaped and headed back to the village, while Kong tore the giant boa's jaws apart and killed it.
Kong followed Dwan and Prescott back to the village and broke through the wall. However, Wilson and the crew had sprung a trap, which Kong fell into. Kong was then smothered with chloroform and knocked unconscious. With no oil to bring back to New York after the oil deposits on the island were found to be worthless, Wilson decided to bring Kong back instead and use him as a publicity stunt. Kong was loaded into the cargo bay of the ship and fed with tons and tons of fruit. When Kong began to go berserk and smash against the wall of the cargo bay, Dwan fell into it, only for Kong to catch her. Dwan's presence calmed Kong, and he set her down then fell asleep for the remainder of the voyage.
When the expedition returned to New York, Wilson arranged a grand exposition for Kong to promote his company. He imprisoned Kong in a giant metal cage, and placed a giant crown on his head. When Kong was mobbed by hordes of media reporters taking pictures, he became enraged and tore through the metal bars restraining him. Wilson tried to run away but was stepped on and killed by Kong. Kong rampaged through the city, destroying cars, stomping on fleeing citizens, and even destroying a train. Prescott and Dwan escaped over the Queensboro Bridge, expecting that Kong would not be able to swim across the East River. However, Kong merely waded across the river in pursuit of Dwan. Kong found Dwan in an abandoned bar and carried her off. Kong noticed the World Trade Center in the distance, and it reminded him of his lair back on his island. Kong climbed the South Tower with Dwan, while the military pursued him. When Kong reached the top of the tower, he was attacked by a group of soldiers wielding flamethrowers.
Kong jumped across the two towers and landed on the North Tower. Out of options, the military sent helicopters armed with machine guns to take Kong down. Kong set Dwan down and swatted at the helicopters, but was mercilessly blasted by machine gun bullets, causing him to bleed profusely. After destroying two choppers, Kong succumbed to his injuries and fell from the tower, plummeting onto the World Trade Center plaza. As crowds of reporters and spectators gathered around Kong, Dwan approached him and looked at him tearfully just as his heart stopped beating.
Thankfully, a female member of Kong's species dubbed "Lady Kong" was discovered in Borneo by Hank Mitchell and brought back to the Atlantic Institute to provide blood for Kong. The transplant was a success, and Kong was revived. However, Kong and Lady Kong mated while in captivity at the Institute, and escaped together. The United States army relentlessly pursued both apes, and tracked them down in the wilderness. Kong fell from a cliff and presumably died in the resulting battle, and Lady Kong was captured and taken to a military base. At the base, it was discovered that Lady Kong was pregnant with Kong's child.
Meanwhile, Kong survived the fall and rampaged through the countryside in search of Lady Kong, although his artificial heart was slowly failing. As Lady Kong went into labor, King Kong arrived near the military base and was attacked by the military. Kong was gruesomely wounded in the battle, but managed to destroy the military's forces and kill the insane army colonel who tried to kill him and his mate. Kong entered the base and collapsed in front of Lady Kong, who had just given birth to their son, Baby Kong. Gravely injured and with his heart about to shut down, Kong smiled as he looked at his newborn child before finally dying. Following Kong's death, Lady Kong and Baby Kong were transported back to Borneo to live in peace together.
Resistance to bodily harm
In the 1976 film, Kong survives getting shredded by machine gun fire and falling from the top of the South Tower of the World Trade Center before falling into a coma. This speaks volumes about his resistance given that exact same drop killed every other incarnation of King Kong to suffer that fate.
