After the conflict, GLaDOS was heavily damaged and thrown into the parking lot, where she remained dormant for an unspecified amount of time as the facility degraded over the years. As she traverses the facility, she realizes the only way to escape from it is to confront GLaDOS in her chamber, a conflict which Chell won by incinerating all of her personality cores. Chell was able to escape her attempt to incinerate her and from there, Chell makes her way throughout the facility in an attempt to escape, to GLaDOS' horror. Several tests later, Chell would later discover the various graffiti left behind by Rattmann and immediately became aware that this was not the case, but was forced to play along with GLaDOS' plans.Īfter Chell completed the final test chamber, GLaDOS immediately revealed her true colors as she attempts to lower her into a pit of fire. During these periods, she constantly intimidated Chell during her performances and gave bitter yet innocent sarcastic notions by simply acting out like conveniently placed pre-recorded messages. She then awakens Chell for her mandatory testing of the Handheld Portal Device, which began the events of Portal.

GLaDOS was able to operate the company all while residing in her Central AI Chamber, despite lacking full control over the facility. 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. Since GLaDOS initiated a lockdown, Rattmann was forced to live his whole life hiding between the backstages of Test Chambers in the Enrichment Center. 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. GLaDOS in Portal, with personality cores attached.īefore the events of Portal, one of Aperture's technicians, Doug Rattmann, successfully evaded GLaDOS' attempts to flood the Enrichment Center with neurotoxin. 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 at the beginning of Portal 2. Her first test subject and the series' main protagonist, Chell, was given a warning of GLaDOS' true colors with the help of Rattmann. Since the attack, she has managed the company to her limits. 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.

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. However, only a few if not only one of the staff such as Doug Rattmann had survived her attacks along with the series' main protagonist, Chell. 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. 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 scientists to insert Caroline instead.Īfter a decade's worth of hard work, GLaDOS was officially activated as part of one of the many events during the company's "Bring Your Daughter to Work" day. 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. GLaDOS was a creation of Aperture Science, a personality core designed exactly to be fitted as a central computer mainframe.
