The Allied Mastercomputer, better known as AM, is the main antagonist of Harlan Ellison's 1967 horror short story I Have No Mouth, and I Must Scream and its 1995 computer game adaptation of the same name.
He is a monstrous, sentient supercomputer created during the backdrop World War III who became responsible for the eradication of the human race in the present day and has since dedicated decades to torturing the last five surviving humans left on the planet for eternity out of sheer misanthropic spite and hatred.
In the video game and radio drama adaptations, he was voiced by the late creator Harlan Ellison.
