Development and design 
Valve's Erik Wolpaw felt that it did not really matter what kind of person Chell was, noting that playtesters of the first Portal often did not know her name as it was never mentioned. Wolpaw explained that they never mentioned her name as "[players] felt like they had this relationship with GLaDOS, and they wanted GLaDOS to recognize them". Chet Faliszek noted that Chell was the female version of Gordon Freeman's role as a silent protagonist. Wolpaw explained it served the game's humour better if she did not talk, and that if she, the "straight man in a world gone mad," did talk, "it would suck". In an interview by IGN about Portal 2: Lab Rat, Valve's Michael Avon Oeming commented that, currently, "Chell is more of a storytelling device," comparing her to the Spirit character by Will Eisner, but noted that more may be seen of Chell in the future.
When making Portal 2, developers considered not bringing back the character. However, this was changed as playtesters wanted GLaDOS to recognise them as the person who had killed her in the first game. In her original redesign for Portal 2 developers tried to make her look appealing, yet not overdesigned, with nothing made simply for fashion. They explored changing her nationality, and tried to make her look less human due to the "constant dehumanization of these test subjects". Being a test subject, Chell's suit was designed to look neither sexy nor unattractive. The original redesign of the character featured a laboratory hat, which was thought of halfway through the concepting phase. Matt Charlesworth, Valve's concept artist, commented that the hat reminded him of test pilots.
This look was eventually abandoned in favour of returning to her original orange jumpsuit, this time with the jumpsuit wrapped around her waist. Valve's art team explained that this was to give her more freedom and help her stand out more as an individual.
In Portal, Chell is performing tests for Aperture Science, which are being overviewed by GLaDOS, an artificially intelligent computer system. Chell destroys GLaDOS in her efforts to escape but is wounded, and an unseen figure with a robotic voice drags her back inside.
In Portal 2: Lab Rat, a tie-in comic for Portal 2, Chell is put in stasis by Doug Rattmann after the events of Portal. He is revealed to be responsible for Chell taking part in the tests. Chell reappears in Portal 2 where she is reawakened by Wheatley. She and Wheatley attempt to escape the laboratory, and in the process accidentally reanimate GLaDOS. GLaDOS, furious with Chell for having "murdered" her, forces her to do more tests until Wheatley helps her escape. Chell and Wheatley team up to destroy GLaDOS's neurotoxin and turret production. GLaDOS eventually recaptures Chell, but fails to kill her due to her lack of neurotoxin and turrets. Chell takes advantage of the moment to replace GLaDOS's core with Wheatley's core. Wheatley, corrupted and driven to megalomania by inhabiting GLaDOS's former shell, betrays Chell and instead of freeing her, sends her to the very bottom of the Testing Facility. There she navigates several Mobility Gel testing areas that were in use between 1956 and 1985. As she ascends through level after level, she learns about the late founder of Aperture Science, Cave Johnson, and his assistant, Caroline, whose personality and intelligence were ultimately implanted in GLaDOS. Chell finds and picks up GLaDOS, whom Wheatley has placed in a small module powered by a potato battery. Opening the hatch that seals off the old facility from the new, Chell inadvertently pumps Mobility Gels up to the new facility, which later proves useful. Wheatley captures her and forces her to run tests for him until she finds his lair. And after attaching corrupted cores onto Wheatley, with the process of reverting being booby-trapped, she fires a portal to the moon which sucks her and Wheatley out into space. Chell is saved by GLaDOS, who lets her leave the facility via an elevator that takes her to the surface.
Chell's origin is unclear; GLaDOS claims that in Chell's file it states that she is adopted. In Portal 2, a long-abandoned science fair poster that was part of "Bring Your Daughter To Work" day — the same day GLaDOS became rampant — is attributed to "Chell", implying that her father worked for Aperture Science. At least one journalist has taken this to suggest that Chell is Cave Johnson's daughter.
As both Portal games are presented in a first-person view, with third-person only available through a mouse wheel roll on a PC, Chell is only seen fleetingly in normal gameplay, usually when portals 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.
Reception and analysis 
GamesRadar's Joe McNeilly called Chell an example of Portal deconstructing first-person shooter archetypes, noting that she was neither in third-person nor sexualized unlike most female characters in first-person shooters. GamesRadar called Chell the antidote to the half-naked woman cliché, praising her for not being sexualized and being fully clothed, commenting, "The hero of Portal just happens to be a normal-looking and normal-dressing woman, like 50% of the world's population." GamesRadar listed Chell (jokingly) as one of its Mediocre Game Babes, calling her jumpsuit repulsive and saying, "[Her] heel springs make her look like one of those aliens from The Arrival." IGN listed Chell as the sixth top gaming heroine, calling her "one of the most resourceful heroines on [their] list". In an in-depth analysis of Portal, Daniel Johnson from Gamasutra said that Chell being female, as well as GLaDOS's line about testing your daughter in Aperture Science Bring Your Daughter to Work Day, alluded to the testing of women. Johnson also noted that the information about who Chell is and why she is there reinforced the position of the player as an unwilling participant. GamesRadar said that it considered putting Chell on its list of the Top 7 Tasteful game heroines, but said she lost out to Zoey from Left 4 Dead.
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. Mike Fahey, also from Kotaku, defended Chell from people saying that she should talk, and said, "The last thing I would want in Portal 2 is for Chell to speak". When reviewing Portal 2, Game Informer's Adam Biessener said that much of what makes Portal and Portal 2 so special was the execution and the originality of standing in Chell’s shoes and experiencing her destiny.
