One of the key characteristics of GlaDOS is her robotic female voice which often lies, bends the truth or says many ironic things. The dialogue from GLaDOS is an important part of the dark humor and atmosphere of Portal.
GLaDOS already stands, or rather 'hangs', as a large menacing A.I., in the middle of her chamber. She is complete with multiple Cores that are specifically made to form the personality of GLaDOS.
