GLaDOS

Personality:   GLaDOS is amoral and often sadistic. She possesses an extremely dry, bitter, and sarcastic sense of humor; her jokes are usually dark, morbid, or outright cruel. She seems to enjoy making manipulative comments that frighten the subject or undermine their self-esteem, but does not usually express open malice. Instead, she makes snide insinuations, or disingenuously presents her insults as mere statements of objective fact; both Ellen McLain and Jonathan Coulton have described her personality as "passive-aggressive." GLaDOS lies frequently, especially about her own emotional state, often claiming to be pleased or merely disappointed when she is clearly alarmed or enraged. She usually portrays herself as an innocent victim, no matter how obviously cruel her own actions have been. Although it is often unclear whether there is any real point to her experiments, she seems to be motivated by a sincere passion for science, which she regards as her fundamental goal in life. Since the time of Chell's unexpected escape from Test Chamber 19, GLaDOS has shown signs of intense and complicated emotions toward her, seeming to combine hatred with a kind of twisted affection. At the end of both games, GLaDOS sings songs - "Still Alive" and "Want You Gone," respectively - that openly express pleasure or relief at Chell's departure, but hint, in GLaDOS' customary passive-aggressive style, at considerably more complex feelings on the subject. Near the end of Portal 2, shortly before claiming to delete Caroline, she tells Chell, "I thought you were my greatest enemy, but all along you were my best friend." For most of the game, GLaDOS plays the part of an emotionless voice that seems to be reciting pre-recorded scripted remarks. However, it quickly becomes clear that something strange and possibly sinister is going on. GLaDOS is disturbingly unconcerned about situations that could cause Chell's death. Many of her comments are bizarre, and they often have a subtly ominous edge. Important information is often obscured by suspiciously well-timed bursts of static. More than once, she tells obvious lies, then explains it away as a "required test protocol." She also displays an odd fixation with cake, repeatedly promising it as a reward. After Chell escapes her "victory candescence" in Test Chamber 19, GLaDOS, clearly surprised, drops all pretense and begins to show emotion. She at first pretends unconvincingly to be on Chell's side, claiming that her attempts to kill her were merely part of the test, that she is concerned Chell is going the wrong way, and that rewards such as cake will be available if she turns back. When this proves ineffective, she switches to attempting to bond with Chell, reminiscing fondly over their experiences together and offering to simply let Chell live peacefully in another part of the facility. Only when Chell is nearly at GLaDOS' lair does she show her true colors, declaring, "Turn back or I will kill you. I'm going to kill you, and all the cake is gone." When Chell finally reaches the AI Chamber, GLaDOS' Morality Core is detached from the Central Core body and gets incinerated. Her voice then loses much of its computerized tone, taking on a more human, almost seductive manner. She alternates between comments attempting to make Chell feel guilty about her destruction, ostensibly well-intentioned advice suggesting that Chell's best option is to give up and allow GLaDOS to kill her, and open verbal abuse - alleging that Chell is "not smart," "wrong about everything [she's] ever done," and "a bitter, unlikeable loner whose passing shall not be mourned". In the ending song, "Still Alive," GLaDOS insists that she is "not even angry" at Chell - in fact, she is pleased and considers the entire project a "huge success". She claims to be happy on Chell's behalf as well; however, she also implies ominously that Chell would have been better off remaining in Aperture, singing, "When I look out there / It makes me GLaD I'm not you". As for herself, she says, she is happy to remain in Aperture. As these sentiments are clearly at odds with the obvious, intense anger and distress GLaDOS displayed during the game's final boss fight, the song is almost certainly not meant to be taken at face value. After being accidentally booted up by Chell and Wheatley, GLaDOS openly shows emotion right from the start. She displays an intense grudge toward Chell, whom she says "murdered" her, describing the situation as though her partial destruction at Chell's hands was completely unprovoked. As she tests her, she keeps up a nearly continuous stream of veiled threats and passive-aggressive insults, repeatedly implying that Chell is overweight, unattractive, selfish, cruel, and unloved by friends and family. Information revealed in Portal 2 may shed light on some of her behavior in the first Portal. The mainframe that controls the Enrichment Center is hardwired with a compulsion to constantly run experiments, described by Wheatley as "the itch." The system rewards the A.I. with a euphoric reaction upon test completion. Much like a drug addiction, the intensity of the "high" diminishes each time. The diminishing returns seem to spur the production of more intense tests, and can trigger a state of withdrawl that may induce insanity. GLaDOS claims that she was sufficiently motivated by genuine love of science to ignore the addiction, but it remains unclear whether this is true, and whether the "itch" might have had other, subtler effects on her personality anyway. GLaDOS also mentions the maddening influence of the Personality Cores, which she experienced in at least some cases as constantly babbling voices in her mind. Furthermore, we now know that GLaDOS was created on Cave Johnson's orders to house Caroline's personality, and that Caroline seems not to have consented to having her mind uploaded; what effect this traumatic experience had is unclear. As GLaDOS comes to remember her origins, aspects of Caroline's pre-upload personality begin to resurface, and GLaDOS' attitude toward Chell seems to soften somewhat. At first she continues to insult her, but some of her later comments are almost friendly, and near the end of the game she confesses that she realizes Chell was her "best friend all along." She claims to experience the Caroline persona as something like a conscience: "Now I hear the voice of a conscience, and it's terrifying, because for the first time, it's my voice." GLaDOS finds the experience of feeling empathy distressing and unpleasant, adding, "I'm being serious, I think there's something really wrong with me." Even after GLaDOS claims to delete Caroline at the end of the game, her experiences while allied with Chell seem to have had an effect on her. For whatever reasons, her grudge has lessened; GLaDOS implies that her feelings toward Chell have merely changed from outright hatred to apathetic disgust, but her actions may hint at a more complex set of emotions. Although she claims to only free Chell because efforts to kill her have proved so troublesome, this does not seem to explain why she did not delete the Caroline program and kill her during the several hours Chell spent unconscious. Even aside from the decision to release her, GLaDOS' final actions toward Chell seem inconsistent with her previous hostility; it is left ambiguous whether she was responsible for the Turret Opera's farewell, and her motivations for returning Chell's Companion Cube are also unclear. One possible reason might be to remove any possible incentive for Chell to return and attempt to kill her again. In the ending song, "Want You Gone," GLaDOS sings that while she once wanted to kill Chell, she is now satisfied to simply have her out of the way. She expresses relief at being rid of her, suggests condescendingly that Chell is to be pitied for not having an immortal robot body like herself, and finally mocks the idea that she might consider her a friend, declaring, "I don't need anyone now." At the end of the final verse, she sings, "When I delete you / Maybe I'll stop feeling so bad (or GLaD)," with the final line appearing simply as "[REDACTED]" in the lyrics displayed onscreen - suggesting that her feelings toward Chell may be more conflicted than she wants to admit. She also at one point sings, "Now little Caroline is in here too," raising questions about whether Caroline was actually deleted at all. The claim of deletion could have been yet another failed attempt on the part of GLaDOS to provoke a reaction out of Chell. GLaDOS, upon learning of her past, never seems to particularly come to terms with it. She displays a fairly strong dissociation with her human identity, consistently referring to Caroline in the third-person. It seems that GLaDOS has developed an extreme phobia of birds after her experiences as a potato. This becomes most clear during the "Peer Review" DLC, when she expresses extreme fear when ATLAS and P-body find the bird from the single-player campaign nesting in a prototype of GLaDOS's body. She seems to believe the bird is far more dangerous than it really is and also starts to raise its chicks as killing machines, despite the fact that they are not lethal
