GLaDOS is the central core designed to control, guide, and oversee the Aperture Science computer-aided Enrichment Center. With the ability to shift and move facilities and various chambers, the Genetic Lifeform and Disk Operating System is able to achieve a seamless and almost infinite testing design whilst residing in the Central AI Chamber.
She is the antagonist of Portal and the first half of the single-player campaign in Portal 2. In the later half, she briefly becomes a deuteragonist. In the latter game's cooperative campaign, GLaDOS is the testing supervisor of Atlas and P-body.
GLaDOS is voiced by opera singer and voice actress Ellen McLain.
Background
GLaDOS was a creation of Aperture Science, a personality core designed exactly to be fitted as a central computer mainframe. The project began under the oversight of Cave Johnson over the company, and was an attempt to create a fully functional, advanced artificial intelligence which was originally intended to be occupied by Johnson as one of his attempts to cheat death. After it became apparent to Johnson that he may die of moon rock poisoning before development on GLaDOS would be completed, Johnson motioned for the personality core to be based on Caroline instead, where she then ultimately became GLaDOS herself.
After a decade's worth of hard work, GLaDOS was officially activated in 1998, as part of one of the many events during the company's "Bring Your Daughter to Work" day. Since she was able to take control of half of the facility's features, GLaDOS began killing most of its inhabitants by flooding the Enrichment Center with neurotoxin. However, only few if not only one of the staff such as Doug Rattmann had survived her attacks. The destruction of the company also coincided with an invasion of Earth, which had occurred two days after at Aperture's rival company, Black Mesa. This ultimately led to the negligence of the outside world from realizing Aperture's fate, as all attention had been diverted to Black Mesa and the aforementioned invasion.
Since the attack, she has managed the company to her limits. Her first test subject and the series' main protagonist, Chell, was given a warning of GLaDOS' true colors with the help of Rattmann. She confronts GLaDOS in her chamber at the end of Portal, which allowed GLaDOS to develop an even deeper hatred for her after she was awakened in the beginning of Portal 2.
Overview
Portal
Prior to the events of Portal, one of Aperture's technicians, Doug Rattmann, successfully evaded her attempts to flood the Enrichment Center with neurotoxin. He then took refuge in several departments throughout the facility and began tampering with the initial test subject roster, rearranging Chell to the top of the list as Test Subject #1 instead. Since GLaDOS initiated a lockdown, Rattmann was forced to live his whole life in hiding between the backstages of Test Chambers in the Enrichment Center. He then left various warnings of GLaDOS through graffiti that could only be found behind several corrupted wall panels in Test Chambers, in hopes that Chell would later stumble upon them. GLaDOS was able to operate the company all while residing in her Central AI Chamber, despite lacking full control over the facility.
She then awakens Chell for her mandatory testing of the Handheld Portal Device, which began the events of Portal. During these time periods, she had constantly intimidated Chell during her performances and given bitter yet innocent sarcastic notions by simply acting out like conveniently placed pre-recorded messages. Several tests later where the Turrets are finally introduced for testing, Chell would later discover the various graffiti left behind by Rattmann and immediately became aware, but was forced to played along with GLaDOS' plans.
After Chell completed the final test chamber, GLaDOS immediately revealed her true colors as she attempts to lower her into a pit of fire. Chell was able to escape her attempt to incinerate her and from there, Chell makes her way throughout the facility to escape. She later had no choice but to confront GLaDOS in her chamber as there was no chance of escaping, a conflict which Chell won. At the conclusion of the conflict, GLaDOS was heavily damaged, and remained in a dormant status for an unspecified amount of time as the facility degraded over the years.
Portal 2
Reawakening era
Beginning the major events of Portal 2, GLaDOS is reactivated through the accidental efforts of both Wheatley and Chell having tried to access an escape lift to the surface in the Central AI Chamber, as both of them were previously trapped in the building following GLaDOS' destruction. She immediately realizes the presence of Chell and Wheatley standing before her upon awakening. Despite her newly profound hatred for Chell having destroyed her, she uses Wheatley as an object for relieving her anger by crushing him.
GLaDOS then decides to return Chell to the facility's science experiments to further her cause of science, but often makes various taunts in hopes to crush her morale.
However, Wheatley later resurfaces and was still alive despite the critical damage inflicted onto him by GLaDOS. With his help, Chell was able to escape from GLaDOS' testing tracks and went through the facility to sabotage her vital strategy components, such as the production of neurotoxin. Finally reaching her newly redesigned chamber, they were then able to defeat GLaDOS together, replacing her with Wheatley as the facility's overseer. Wheatley, intimidated by GLaDOS' response to how useless he is, traps GLaDOS in a potato battery and throws her into the depths of the Enrichment Center alongside Chell.
After Wheatley became corrupted by his new position and power, GLaDOS and Chell worked together, initially as unwilling partners, to restore control over the facility (which further degraded and corrupted under the influence of Wheatley, to the point where the facility's reactor core will undergo a meltdown). During this time, the duo try to find their way out of the depths of the Enrichment Center where they approach several vintage Test Chambers previously managed by Aperture CEO, Cave Johnson and his secretary Caroline.
As Chell and GLaDOS continue to journey through the pasts of Aperture Science located in the salt mine deep beneath the Enrichment Center, GLaDOS slowly becomes familiar to Johnson and Caroline. As they are finally ready to leave the salt mine, GLaDOS has an epiphany on who Caroline is but remains silent on the matter.
The duo then have made their way back to the modern Enrichment Center, where Chell and GLaDOS were put through Wheatley's testing tracks. When Wheatley later realizes that GLaDOS had built two robot test subjects prior to Chell and Wheatley's sabotage over the facility early on in the game, he finally attempts to dispose both GLaDOS and Chell. When the duo manages to escape from his grasp, they head to the Central AI Chamber to confront him. GLaDOS proposes that Chell is to attach her back into her body to resume her control over the facility. The conflict was then resolved by their conjoint efforts, resulting in the exile of Wheatley to outer space and a reconciliation between each other.
After repairing the entire facility to its state prior to Wheatley's control, GLaDOS begins to become even more affected by her recently acquired morality, emotions and gained her own consciousness after discovering who Caroline was. She realizes that Chell was not an enemy, but could be considered a close friend. Part of her "rogue AI" nature disagreed with this change of heart. GLaDOS was then able to trace Caroline's consciousness in her system, moments before the Announcer reveals that GLaDOS has deleted Caroline from her system. She then expels Chell from the facility in order to avoid further trouble beyond her control. However, Chell is then comforted through her elevated ride to the surface by a Turret Opera which remains unknown as to why the event occurred.
Before Chell could leave the Enrichment Center for good, GLaDOS decides to return Chell's Companion Cube from her tests in Portal by ejecting it from the lift and onto her before the door to the Enrichment Center could shut itself.
From then on, she conducts tests on the two robot test subjects; Atlas and P-body.
Cooperative testing era
Sometime after Chell is freed from the Enrichment Center, GLaDOS has been primarily focusing on her two new android test subjects, Atlas and P-body. Typical to her nature, she would constantly find a way to crush their spirits via sarcasm and rarely having much hope in them.
At the end of the first test course, Team Building, she deploys the bots outside the official testing track, announcing that "this next test is so outside the box that I can't- I mean WON'T even tell you what you're looking for". She leaves the bots to use common sense to figure out what they should be looking for by themselves, as they find a large disc and bright it into a projector room. Despite the clear warning "DO NOT TRUST HER" written on a whiteboard in the room, the bots were loyal to GLaDOS and placed the disc into the projector - in which she begins scanning for files and documents she never disclosed. After she was done, she initiated a self-destruct on the bots and reassembled them back at the hub.
This went unmentioned through the entirety of their second testing track, Mass and Velocity. However, at the end of this course, it became clear that she would send them outside the testing tracks again to handle her secret full takeover on the facility. As Atlas and P-body worked together to get each other past the air circulation maintenance section, they found another disc and installed it into the projector. GLaDOS began scanning for projects and tells them that she did not really need them to do this, and pretended it did not matter after self-destructing them.
When the bots had unlocked the third course, Hard Light Surfaces, GLaDOS' utter disappointment in the duo was becoming more clear. With their deaths never bringing the satisfaction she had with the death of humans, as the bots could just easily be rebuilt again each time they are destroyed - she secretly worked on an attempt to replace Atlas and P-body. At the end of this course, the bots install a disc which contains the Enrichment Center's current overall security code, which she tried to block out from their range of hearing by uttering "blah blah blah" repeatedly as the Announcer relays the codes.
In the fourth course, Excursion Funnels, GLaDOS builds slight hope in keeping Atlas and P-body still as predicted by her sudden change of mood from the previous course. She now wants the bots to feel conflicted against each other - hoping to enhance a more "competitive" and bitter testing run, simply by manipulating them into thinking that one of them has been "reporting" to her behind the other's back, or how P-body was not Atlas' first cooperative testing partner. No matter how many times she tried to stir the two apart, the bots would brush her lies aside, where GLaDOS' disappointment in the two had returned again in her tone of voice. At the end of the test, she convinces them to install the final disc to her full control over the facility - telling them it was a clerical error on how it was not done any earlier. After the bots installed it, overview maps of every section of the facility was shown in the screen, followed by her mischievous yet anticipated tone of voice when revealing that "[she] can see everything now".
Reassembled back at the hub, GLaDOS tells the bots that they have just one more testing course to complete - Mobility Gels. She deploys the entrance to this course into the hub, and sends them deep beneath the Enrichment Center to the Aperture Science Innovators era, a bottom section of the salt mine. GLaDOS convinces them to rescue the "dying, trapped, crying" live human test subjects preserved in a cryogenic vault that were preserved since the 20th century. Once they finally reach to this vault at the end of the course, GLaDOS reveals a great deal of anticipation and obsession over "rescuing" them. In attempt to unlock the vault, the bots had to perform gestures like any human would - as the vault was an anti-robot section. Despite how sinister she sounded after the bots observed the hundreds of humans in cryogenic stasis, they disregarded it and began dancing in triumph. Now extracting all of the human test subjects, she begins processing their files - which apparently turned out to be only one person's file.
As she no longer needed Atlas and P-body as her test subjects, she began testing the humans in an attempt to develop them into her cold minions. Her ultimate plan failed as the humans were unable to withstand her extreme testing courses and all of the hundreds of test subjects that were found died within just a week of testing. It became apparent that she absolutely needed Atlas and P-body back as her facility began to malfunction quickly, in addition to her lack of test subjects.
When the bots are rebuilt again, she sends them to a new testing course dubbed as Art Therapy, constantly treating the test course as if it were an art museum despite the malfunctioning environment such as her lack of control in putting the test chambers together properly, and a flood arising around a section of the facility during testing. And later, the reassembly machines have finally malfunctioned - causing her to wait three days before the robots could be reassembled to deliver the duo to their next test chamber. After the problems became clear, she confesses that she does need their help and that someone has been tampering with the facility via control of an old prototype chassis of the central core. To resolve this problem, she trains the bots into becoming her "killing machines" by sending them through even more excessive training during their test course. GLaDOS then finally sends them closer to the location of the chamber housing her chassis, in which she jokingly dubs them as her "Special Team Falling Into Acid Force". When the bots reached the chamber, they discover it was never a person controlling the chassis, but a bird nesting above the keyboard on the machine. As GLaDOS observes it, she panics and yells at them to abort their mission, before P-body closes a hatch that the bird flew out from. As the bots stare at the machine, GLaDOS observes the eggs on the bird's nest and panics that the bird had been "gestating clones" and forces them to destroy the eggs. As the bots were hesitant, she conjures a better idea and houses the birds in the Central AI Chamber, where she could talk with them directly.
After several insults on how the birds were "abandoned" for how worthless she deemed them, she immediately saw potential in them when one of the birds cracked the glass casing housing them with its beak. GLaDOS begins to show compassion toward the birds as she realizes their ability to use hostility and makes use of them as test subjects, as she reveals a more motherly bonding with the birds than she ever did with the bots. The fate of the birds will remain unknown until further test courses are added.
Abilities and Traits
As the overseer and operator of the facility, GLaDOS is seemingly omnipotent, able to reconfigure rooms and carry out actions at her will. She monitors the facility and its test chambers through cameras mounted on walls. She also mentions that she cannot resist thinking of paradoxes if one would happen to be brought up. GLaDOS had displayed little to no emotion within her voice tone in the first half of Portal, due to being bound by the consciousness of other personality cores attached onto her for the sole purpose of restricting her control. She then becomes increasingly more agitated and is portrayed as intimidating near the end of the game. In Portal 2, she becomes extremely bitter after the events of Portal, frequently insulting Chell until the very end - where she realizes that Chell was "all along [her] best friend".
GLaDOS' consciousness had been controlled by personality cores throughout the events of Portal. If the cores are removed, the traits and morals which the cores contain would be permanently detached from GLaDOS as well, causing her to fall back to her more human and intimidating voice tone, resembling to that of her Genetic Lifeform component Caroline.
It was eventually revealed in Portal 2 that GLaDOS was also able to reconstruct the components on her own body as well, now without the cores restricting her thoughts. She had replaced most of the broken and or missing components on her body since her awakening in the chapter, The Courtesy Call. Her newer components are sleek and black, and is of little resemblance to the original ones from her body during the awakening and Portal.
Development and Acting
During Anime Midwest 2011, voice actress Ellen McLain revealed that the concept of GLaDOS had always been a robotic voice that would pretentiously guide someone and often intimidates them. At this time, the developers had used copyrighted voice samples as a placeholder (temporary placement). As Ellen McLain had voiced the radio communications dispatcher of the Combine Overwatch throughout the Half-Life 2 saga, the developers had chosen her for the role of GLaDOS. During this time, developers had kept the project a secret and had left Ellen unaware what game it is that she is voicing for. Ellen was later made aware of her work and success when Portal was finally released.
In Portal, GLaDOS' initial designs prior to the game's release vary greatly. The earliest known design of GLaDOS was a large disc with a red eyeball in the center, with the disc surrounding it and welded onto the eyeball. This concept of GLaDOS appears to be the most favorable version towards several community members and was then recreated for use by a new character entirely for the community-made machinima series, The Underground. Later on in development, the design of the large eyeball was then scrapped into a robotic body hanging upsidedown from the ceiling, with four discs surrounding above it this time. This concept has since been kept for the release of Portal, with minor adjustments such as the addition of personality cores.
The earliest known concept of GLaDOS in Portal 2 demonstrates that her body's plating was completely torn and scrapped, leaving only her head the most intact - nearing the design of her spherical-cylinder shaped head in the game's release. She had also been given a red eye color in this concept rather than her trademark yellow that was given to her in Portal. Not much else is known of her design changes for the sequel, except that the developers established that the current design of GLaDOS in Portal 2 was to signify a more antagonistic appearance and shape.
In addition, a reskin of GLaDOS' design from Portal can be found in the game files of Portal 2, presenting rust stains and scratches possibly to be used for her components scattered around in her chamber.

Trivia
- The acronym "GLaDOS" is a pun of the name "Gladdys" and the term DOS (Disc Operating System).
- Ellen McLain, the actress that voices GLaDOS, also provides the voice for the Administrator in Team Fortress 2 and the Combine Overwatch in the Half-Life series. This makes Ellen McLain the only voice present in every game included in the The Orange Box.
- The most favored character that Ellen McLain has voiced is none other than GLaDOS. She reveals that despite the hard effort in pulling off the voice of the Administrator from Team Fortress 2 and her unique way of ordering things, GLaDOS' character had a greater impact on her through her popular passive-aggressive behavior and subtle insults.
- During the development of Portal 2, playtesters were uncomfortable with GLaDOS as she was far too vindictive in the single-player campaign, and the developers concluded that some of her dialogue was too extreme. Due to this, elements of her dialogue were reworked, which resulted in the creation of a more amicable, passive-aggressive personality for GLaDOS.
- The acronym "GLaDOS" was never pronounced or spoken in full in the entire series. The only instances of her name are through in-game captions during Portal 2, and one of her disc generators from which the acronym was only present in Portal. During dialogue in Portal 2, Wheatley would only refer to GLaDOS as "her" or "she".
- When in her potato battery form, she is commonly referred to by the community as "PotatOS;" this nickname is derived from the word "potato" and her name, GlaDOS.
