Portal Series

Character Analysis

(Avoiding Spoilers)

Living… deep within the abandoned Aperture Science Laboratories. GLaDOS, (which stands for Genetic Lifeform and Disk Operating System) is an unstable artificial intelligence program who went on a murderous rampage and killed all of the employees in the facility by releasing her favorite deadly neurotoxins. As she tells her test subject, “I could take a bath in this stuff. Put in on cereal; rub it right into my eyes. Honestly, it’s not deadly at all…to me. You, on the other hand, are going to find its deadliness…a lot less funny.”

Profession… overseer of the Aperture Science Enrichment Center. GLaDOS is an AI created to administer and supervise testing within the Aperture Science Laboratories. Her job is to provide helpful advice and guide the test subjects, although she seems to take a kind of pleasure in their fatal failures.

Interests… testing, science, and cake. GLaDOS loves setting up puzzles and conducting experiments in the name of science. She also possesses a strange predilection for cake and often invites subjects to have cake and a party as a reward for testing.

Relationship Status… single. GLaDOS is just a lonely AI robot looking for friends. Living in isolation for so long has made her desperate to talk to and play with somebody.

Challenge… test the last remaining test subject in the facility…and murder her. GLaDOS likes to toy with her subjects and will do anything in the name of science. But her test subject Chell wields the powerful portal gun that allows her to place portals on the walls of the facility and travel between them, and she might just prove to be GLaDOS’s downfall.

Personality… murderous, amoral, and manipulative. GLaDOS is sadistically playful and a passive-aggressive liar. Despite having a morality core installed, GLaDOS doesn’t seem capable of understanding that her actions might be wrong, and is immune to appeals for pity or mercy. She possesses a morbid and sarcastic sense of humor as well as an unhealthy obsession with murder. As she relates to her test subject, “Killing you and giving good advice aren’t mutually exclusive.”
