Ellen is the deuteragonist of the late Harlan Ellison's short story I Have No Mouth, and I Must Scream. Ellen has been tortured by AM for over 109 years. She displays a great degree of empathy and morality compared to the other survivors; however, as Ellen is the only female survivor, the others use her sexually by AM's design.

Before being captured by AM, Ellen supposedly prized her chastity above all else - a trait AM took great delight in twisting beyond recognition. By the start of the story, Ellen is obsessively promiscuous, driven by the supercomputer's mental distortion to seek out sex from any of the other survivors; however, she never enjoys sex with any of them save for Benny - a fact that Ted, secretly infatuated with Ellen, deeply resents. As the only member of the group she likes to any meaningful degree, seeing Benny harmed is guaranteed to drive Ellen into a hysterical fit.

The rest of the survivors treat her with a mixture of protectiveness and contempt depending on the severity of the torture: during the journey's calmer moments, they happily carry her; conversely, when Ellen is lying on the floor after suffering a breakdown at the sight of Benny's punishment, Gorrister goes so far as to kick her in the side.

However, she is still intelligent enough to recognize Ted's plan to mercy-kill the survivors, and follows suit in killing Nimdok, before Ted kills her as well.
