GLaDOOOOOOSSSS
aka caroline aka tragic evil robot wife </3 aka Genetic Lifeform and Disk Operating SystemBackstory
GLaDOS originated from Caroline, Cave Johnson's assistant, who was put into a computer (likely without her consent) after presumably Cave was too dead to put into one. When she woke up she was imo understably pretty pissed off about all that so killed everyone with neurotoxin.
