He is the main protagonist of the movie of The Thing 1982

Section heading
A Norwegian helicopter with two Norwegians aboard pursue an Alaskan Malamute to an American Antarctic research station. As the Americans run out, a Norwegian rifleman attempts to throw a thermite charge at the dog, but accidentally drops it- which destroys the helicopter and kills the pilot in the process. The rifleman keeps firing at the dog until he is killed by Lt. Garry, the station commander. Helicopter pilot R.J. MacReady and Dr. Copper fly to the Norwegian camp for answers, but find only a burned ruin, with the body of a man who committed suicide and a large block of ice with a hollowed cavity. Outside they discover the burned remains of a humanoid corpse with two faces. Back at the station, the biologist Blair performs an autopsy on the creature, but finds only a normal set of internal organs.

Clark kennels the Malamute with the station's sled dogs, where it begins to metamorphose and attacks them. MacReady pulls the fire alarm when he hears the commotion, gathers everybody to the kennel, brings a shotgun, and calls for a flamethrower. Childs incinerates half of the creature, but the other half escapes. Blair's analysis leads him to believe it is capable of perfectly imitating other lifeforms, and he withdraws from the others. The Norwegians' records lead the team to a crater containing a flying saucer and a hole left by the block of ice from which they suspect the creature came. Fuchs tells MacReady that according to Blair's journal, the creature's "dead" remains are still active on a cellular level. Blair calculates that if the alien escapes to a civilized area, all life on Earth will be assimilated in three years.

Bennings is killed by the creature but he is caught outside by the team before his metamorphosis is complete, and MacReady burns him before he can escape. Garry realizes Blair was absent. MacReady sees Blair running inside and discovers he has wrecked the helicopter; Childs confirms that Blair also destroyed the other transports and killed the remaining sled dogs. The team corners him as he is destroying the radio, then locks him in the tool shed. Determined to learn who is infected, they discover the blood stores have been sabotaged before they can perform the blood-serum test Copper recommends, and the men begin to turn on each other. MacReady takes charge and orders Fuchs to continue Blair's work, but Fuchs disappears when the power goes out. As a storm closes in, MacReady, Windows, and Nauls continue the search for Fuchs outside where they eventually find his burned body. Windows goes back to tell the others, and MacReady takes Nauls to check out his shack, where the lights have mysteriously come on. On the way back, Nauls cuts MacReady loose from the tow line, assuming he has been assimilated when he finds a torn shirt with MacReady's name on it. As the team debates MacReady's fate, he breaks in and threatens to destroy the station with a bundle of dynamite if they attack him, and Norris suffers a heart attack.

When Copper attempts to revive Norris by defibrillation, his chest gapes open and closes like a giant mouth, biting off Copper's arms, who quickly dies from the injuries. MacReady incinerates the creature and orders Windows to tie up everyone for a new test, killing Clark when he tries to resist. MacReady explains his theory that every piece of the alien is an individual organism with its own survival instinct that will react defensively when threatened. One by one he tests everyone's blood with a heated piece of copper wire. They are all still human except Palmer, who begins to metamorphose and attacks Windows, forcing MacReady to burn them both.

Leaving Childs on guard, the others head out to test Blair, only to find that he has tunneled under the tool shed. They realize that Blair is an alien who has scavenged the equipment he appeared to destroy in order to build a small escape craft. MacReady speculates that the alien intends to freeze itself until a rescue team arrives in the spring. They decide to dynamite the complex hoping to destroy the alien but Garry and Nauls are killed by Blair before they finish setting the explosives underground. Blair transforms into a larger monster and attacks, but MacReady dynamites the monster and the base explodes as he escapes.

Stumbling through the burning ruins, MacReady finds Childs, who claims he got lost in the storm while pursuing Blair. Exhausted, exposed and facing imminent death from the cold, they acknowledge the futility of their distrust, sharing a bottle as the camp burns.
