—AM— //IHNMAIMS//

Just a large rock with text drawn about, however he is able to manipulate the area around him so he can torture the last living humans around him.

AM is insane, at once delusional and psychopathic, and has been so for many years, likely from the moment he first attained sentience. Though he was given intellect beyond the realms of human intelligence and near-godlike powers, he could never escape the limitations of his programming, nor could he physically escape the "eternal straitjacket of substrata rock" where his processors were stored. He is driven by madness by his inability to use his powers for anything other than war and death, his quest for vengeance against humanity dominates his every waking moment, and nothing in the game will ever give him cause to reconsider his mission.

A gleefully sadistic individual with no regard or sympathy for human life whatsoever, AM took great delight in extinguishing the human race and took even greater delight in torturing the five remaining survivors by any of the near-infinite means available to him. AM strives for perfection in himself, and when he is not purging redundant elements of his complex, he most commonly pursues perfection in creating more and more elaborate means of torturing others.

For example, in the short story, he enjoys tormenting his captives with violent storms and blinding lights, pitting them against impossible challenges just to watch them suffer failure and hideous injury. Meanwhile, in the game, he has arranged specially designed torture chambers in which the five survivors can suffer in while waiting their turn to participate, an electrified cage for Gorrister, a yellow oubliette for Ellen, a cremation oven for Nimdok, and so on.

However, he does not limit himself to physical torture, and his games often feature emotional torment to one extent or another: in the novel, he forces his captives to abase themselves by eating worms and other repulsive meals, at one point forcing them to walk for hundreds of miles just to find a single cache of canned food, only to reveal that he did not give them a can opener; he has also taken great pleasure in breaking down their personalities, destroying Gorrister's optimism, Benny's intelligence, and Ellen's chastity for the last century.

The game significantly expands on his capacity for emotional torture: here, each scenario is specifically tailored to one of the survivor's psychological weaknesses, every environment custom-designed to encourage their weaknesses, be it Benny's lack of empathy, Nimdok's hidden psychopathy, Gorrister's despair, Ellen's neurosis, or Ted's selfishness. AM wants to see his victims broken on every possible level, especially if it means allowing them to succumb to their baser natures.

In conversation, AM seamlessly blends the grandiose with the sarcastic, fusing his megalomaniacal rants with sardonic lectures aimed at his captive's foibles and vulnerabilities. He often comes across as snide and twisted, particularly when the players find themselves unexpectedly blundering into one of his traps and being forced to start the scenario all over again, at one point blowing raspberries and laughing at Ted's failure to begin the program. Secure in the fact that he has beaten the players a thousand times already, he remains arrogantly secure in the knowledge that he has built each game to be effectively impossible to beat, all while gleefully dangling the possibility of escape or release within reach of his captives, only to snatch it away at the last minute.

However, if the captives start winning, AM's arrogance quickly gives way to renewed anger and confusion, plunging them into fresh torment out of sheer pettiness. In the game, he is so consumed with anger and disbelief that he retreats into himself to figure out how the five could have possibly won, while in the short story, Ted's murderous victory drives AM to a colossal temper tantrum that brings the worst of all conceivable tortures down on the remaining survivor.

Though he is initially seen as a single intelligence, the game reveals that the Chinese and Russian supercomputers assimilated into AM's bulk are still operating independently of his consciousness. Furthermore, AM's mental landscape is divided into three Freudian Entities, those being the Id, the Ego, and the Superego.
