"It's been fun. Don't come back." - GLaDOS' last words to Chell after letting her go in Portal 2.
GLaDOS or Genetic Life and Disk Operating System is the main antagonist in Portal. She is SHODAN's daughter and is voiced by Ellen McLain.
GLaDOS' is an AI created at Aperture meant to help advance research but she went crazy and killed a almost all of the people at Aperture during the first "Take your daughter to work day". Later after a bunch of other off-screen events and with all the other human test subjects dead GLaDOS wakes up the last human test subject named Chell and has her do a bunch tests that involves portals. After finishing them GLaDOS then tries to kill Chell but Chell escapes and then makes her way to confront GLaDOS. When Chell finally arrived, she fought GLaDOS and killed her.
Decades later, GLaDOS returns to life by Chell and Wheatley and then she goes back to making Chell doing tests while trying to make life even more horrible. But thanks to Wheatley, Chell escapes and takes out her defenses, and then when Chell meets GLaDOS again, they fight again and then Wheatley takes over Aperture. But Wheatley becomes evil and then puts GLaDOS into a potato, and GLaDOS remembered Wheatley how he was made to make her into an idiot. Wheatley got mad at this and sends both her and Chell into the bottom of Aperture. Chell save's GLaDOS from a bird that was trying to eat her and they decides they need to work together to stop Wheatley.
When they reach the top again, Chell does more tests and escapes a bunch of death traps made by Wheatley and then they finally reach his lair. Chell puts a bunch of corrupted cores on Wheatley making him corrupted enough for GLaDOS to take over again. When she took over, Wheatley was sent to space. Afterwards, she decides to let Chell go free because she was pretty much sick of having to fight with her.
