GLaDOS also reveals in Portal 2 she found two cryogenic test subjects with Chell's last name, suggesting her parents survived the science fair, though again, this could be more mind games on the A.I.'s part. The sequel does end on something of a happy note for Chell, who is ejected from the facility by GLaDOS, but her past remains a mystery.
However, the staff commentaries on Portal 2 pronounce her name as in church rather than Mi ch elle. "Chell" is never given in-game, but is mentioned in the Portal end credits and can be found in the game files for both Portal and Portal 2.
Kotaku 's Luke Plunkett called Chell's original design in the first game memorable, later noting how in the first Portal "Chell [...] was never really the star of the game" as well as how little she was actually seen.
In the end, the outfit chosen for Chell in the final, retail version of Portal 2 had her wearing her jumpsuit from the first game, though her upper body is disrobed and the upper half of the jumpsuit is tied around her waist, revealing a white tank top with the Aperture logo on it. She also wears a white band around part of her right forearm.
In the events of the second game, Glados discovers she is Caroline (basically) and that Chell was her daughter.
About around the time of the Portal 2 Announcement ARG, to the best of my knowledge it had become well established that Cave Johnson was Chell's father (with the latter being abducted by GLaDOS on Bring your Daughter to Work Day).
Many people beleive that Chell's parents are Cave Johnson and Caroline, and that Doug Rattman is Chell's adopted father. I even beleived that at some point. But now I have proof it isn't true.
1. GLaDOS says multiple times that Chell was adopted. 2. Chell is(was) the child of one of the employees at Aperture science and came in for bring your daughter to work day were she made a potato for the science competition that mutated out of control.
In the events of the second game, Glados discovers she is Caroline (basically) and that Chell was her daughter. She becomes more protective and loving torwards Chell. At the end of the game, she says that she deletes Caroline.
Chell is an "orphan" and there by has no record of parents or family.
At the end of this main campaign, GLaDOS writes a note to Chell stating that she's been fine going on her own adventures, but "you wouldn't know, would you?" It is obvious that GLaDOS misses having Chell and/or other humans around for testing.
Cave Johnson's physical appearance is based on that of Portal 2 lead animator, Bill Fletcher.
However, he appears in hidden areas of the facility to Chell, and later helps her defeat GLaDOS by replacing her program in the main control system with himself. But right when Wheatley is about to let Chell go free, he becomes corrupted and betrays her, accusing her of selfishly using him.
TL;DR: Chell had been living since she was very young at Aperture Laboratories, her parents are Cave Johnson and Caroline, and when GLaDOS realizes she is Chell's mother she decides that testing is unsafe for her daughter so she sends her to the surface.
Cave Johnson started the GLaDOS project as a way to cheat death before he died from his moon rock poisoning.
Chell is a clone. During the Lab Rat comic, GLaDOS mentions offhandedly to Doug Rattmann (as he is editing Chell's Test Subject position) that “clones don't have souls.” He is certainly not a clone, and why would GLaDOS randomly mention clones to him?
At the beginning of Portal 2, she is woken up for the first time after 50 days of sleep after the events of the Lab Rat comic, for a mandatory set of physical and mental exercises.
GLaDOS attempts to deploy a "surprise" to eliminate Chell but ends up "accidentally" detaching her Morality Core, claiming she has never seen it and does not know what it is. Chell promptly incinerates the core. GLaDOS' remains on the parking lot, shortly before Chell is dragged away by the Party Escort Bot.
Sometime after GLaDOS' takeover of the Enrichment Center and shortly after the Combine invasion of Earth, Chell is awakened from some sort of stasis pod in a Relaxation Vault by GLaDOS. Chell is released from the Vault through a Portal and begins to progress through a series of Test Chambers that require her to solve puzzles revolving around the use of the Aperture Science Handheld Portal Device (ASHPD). Throughout the tests, GLaDOS guides Chell with what sound like pre-recorded scripted instructions; however, her comments are strikingly bizarre, and often seem to malfunction at suspiciously well-timed points in mid-sentence.
The furnace after Test Chamber 19. At the conclusion of the test, Chell travels on an Aperture Science Unstationary Scaffold away from the final Test Chamber. Instead of the promised cake, she is met with a pit of fire. To GLaDOS' surprise, Chell does not panic or give up in despair.
Chell had been rejected as a candidate for testing due to her psychological profile, which showed her to be an extreme outlier in terms of tenacity. Rattmann, having correctly guessed that such stubborn determination might be the key to escaping, hacked the system to make her test subject #1.
Chell facing GLaDOS in the latter's chamber.
Furious at both GLaDOS and Chell, Wheatley begins smashing Chell's elevator into the ground , sending them down the elevator shaft and into the bowels of the facility. Chell wakes up in the deepest part of the Aperture Science, which contains the old facility from as far back as the 1950s.
Some posit that Chell is the daughter of Cave Johnson, the founder and CEO of Aperture Science.
In Portal, Chell is performing tests for Aperture Science, which are being overseen by GLaDOS, an artificially intelligent computer system. Chell destroys GLaDOS in her efforts to escape but is wounded, and an unseen figure called the Party Escort Bot drags her back inside.
GamesRadar called Chell the antidote to the half-naked woman cliché, praising her for not being sexualized and being fully clothed, comment ing, "The hero of Portal just happens to be a normal-looking and normal-dressing woman, like 50% of the world's population.".
Chell's face and body model were derived from Alésia Glidewell. She experienced a redesign in Portal 2 which was often changed during development. For example, the original redesign featured a laboratory hat. A character presented in first-person perspective, Chell can only be seen through reflections and portals in the game.
Chell is a playable character in the crossover game Lego Dimensions, and has access to her portal gun. Her character pack includes a sentry turret and a companion cube, and unlocks a bonus level in which she returns to Aperture and is reunited with Wheatley, with the two trying to stop GLaDOS once more.
Chell's face and body model were derived from those of the director, producer and voice actress Alésia Glidewell.
As both Portal games are presented in a first-person view, Chell is only seen fleetingly in normal gameplay, usually when portal s are aligned in such a way that the player is able to create a recursive view of Chell. Placing two portals next to each other on a wall and then partially entering the one portal while facing the other allows the player a close-up view of Chell's face.
Chell was in the Aperture Laboratories at the time of GLaDOS' takeover, meaning she had some business there. This is supported when GLaDOS angrily tells her "You're not smart. You're not a scientist. You're not a doctor. You're not even a full-time employee!", suggesting she had some sort of part-time job at Aperture.
As a Test Subject, Chell also is fitted with Advanced Knee Replacement, small spring devices surgically attached to her legs that assist her jumping and walking skills and allow her to fall great distances without being hurt.
Chell. Chell is an Aperture Science Test Subject, and the esoteric, silent protagonist of Portal and Portal 2 .
activation. Chell appears to be in her late 20s or early 30s, and of mixed ancestry or possibly Latin or Japanese descent (Chell's face and body model, Alésia Glidewell, is of Brazilian and Japanese ancestry), and is rather thin.
Based on her success in the Test Chambers and subsequent escape, it can be sur mised that Chell is highly determined and a quick, inventive thinker. Other than that, little is known about her personality and background. All further information about her comes from comments by GLaDOS, who is by no means a reliable source of information, since she seems to often lie to Chell to make her feel guilty about her actions. For instance, according to GLaDOS, Chell's personnel file says she was adopted and is "unlikable" in character.
Chell is awakened by GLaDOS some undisclosed time after this to test the Aperture Science Handheld Portal Device - AKA the Portal Gun - but has no memory of her past. GLaDOS also reveals in Portal 2 she found two cryogenic test subjects with Chell's last name, suggesting her parents survived the science fair, though again, ...
Portal 2 reveals GLaDOS went rogue during Aperture Science's Bring Your Daughter to Work Day, with one of the science-fair entries involving a potato signed by Chell. This means she was almost certainly a daughter of one of the scientists working at the facility.
GLaDOS was activated during the Bring Your Daughter To Work Day event and she killed most of the scientists present with neurotoxin. In a case of lucky timing on her part, the alien invasion caused by the Black Mesa incident in Half-Life happened around the same time, meaning nobody came to Aperture to investigate.
The critical acclaim that greeted Portal spurred Valve on to make Portal 2, which was released in 2011. The game once again found Chell forced to undergo a series of tests by rogue A.I. GLaDOS, until the two are forced into a reluctant partnership midway through the campaign.
Some of these details are thrown out by GLaDOS herself, who hints she was abandoned at birth and adopted, but given the A.I.'s other lies and manipulations, her word can't really be trusted.
Like Half-Life's Gordon Freeman, Portal's heroine Chell remains mute for the entire game. In fact, she isn't even named in the first game.
Chell was the silent protagonist for both of Valve's Portal games but what is her backstory and connection to Aperture Science?
This could be considered too localized. At this point, there's no official 'canon' answer.
As of Portal 2, speculation tends to lean in the direction of Cave being Chell's father.
Players exploring the Aperture facility in Portal 2 can discover a presentation from the Bring Your Daughter to Work Day science fair signed with the name Chell. Several girls seem to have made potato batteries; none of them have rotted over the years, but Chell's potato has actually grown out of control, sprouting through the ceiling.
GLaDOS figured out who she was when she spent the long time “thinking things over”, and when she was done with that she came to the conclusion that she was really part human, and she remembered her previous life as Caroline/mother to Chell.
If you look closely on the corner of the poster for that experiment, you will notice a little scribble that says “By Chell”. This means that Chell made that experiment (there aren’t a whole lot of other girls named Chell) and is the daughter of an Aperture employee. Specifically the daughter of Cave Johnson and Caroline.
EDIT3: * GLaDos claims " I have your brain scanned and permanently backed up in case something terrible happens to you, which it's just about to. "
There are three main theories for Chell's origin. 1) She is one of the orphans paid by Aperture for testing. 2) She is the daughter of one (or two) unnamed scientists. 3) She is the daughter of Cave and Caroline.
Since GLaDOS's homicidal rampage happened in 200X, any daughter of Cave's would have to be 23+ by that point. Thus, Chell cannot be a daughter of Cave Johnson. TL;DR - Cave died before Chell was born. Please become a fan of my cat.
