GLaDOS from Portal
The artificial intelligence antagonist of the Portal series is an incredible shit-talker. GLaDOS initially presents herself as a simple AI that observes your actions all under the guise of monitoring “tests.” But once her mask comes off and you know she’s a vindictive fuck who wants you dead, she starts spitting some of the meanest, pettiest shit she can. Her begrudging partnership with you in Portal 2 is peppered with constant dunks on your character, personality, looks, and the fact that your mother left you on a doorstep, allegedly. She is always looking for a reason to tell you that she wants you dead, and if she can’t find one, she’ll make one up.
