Other than "GLaDOS" being printed on one of the rings above her cores in Portal (not even sure if it appears in Portal 2 due to the reskin), is "GLaDOS" ever spoken in either game? Wheatley simply refers to her as "her"

Wheatley: In order to escape, we're going to have to go through HER chamber. And she will probably kill us if, um, she's awake.

Further, does Wheatley ever introduce himself? The loading screen in later chapters reads "Wheatley Laboratories", but does that printing show up in-game at all? GLaDOS just says "him", "you", etc.

GLaDOS: He's not just a regular moron. He's the product of the greatest minds of a generation working together with the express purpose of building the dumbest moron who ever lived.

And finally, is Chell being called Chell purely Word of God or is there something in-game that mentions her name?

  • IIRC 'Chell' was written on her outfit/nametag but I could be wrong

  • When you put subtitles the characters are effectively Wheatley and GLaDOS, appart from that, severals elements in the lore thend to prove it but I don't think its specifically stated in the game. Gotta check that

Well, other than that unused GLaDOS voice line saying Chell, there is one other time where a name is mentioned: When Wheatley has just replaced GLaDOS.

"I did this! Tiny little Wheatley did this!"


Also in the Turret Opera, the fat turret (also known as the Opera Turret) sings right at the beginning:

Cara bella, cara mia bella! Mia bambina, o ciel!

"Ciel" means "heavens" in Italian, but it sounds a lot like "Chell"...

And in the subtitles it says "GLaDOS" and "Wheatley" beside the text.

  • Turret opera, sais ciel (heavens) or Chell. I believe that wheatley said glados in The beginning of portal 2. Not sure.

  • Good catch with the Wheatley quote!

Names are very rarely used in the Portal series (aside from Cave Johnson and his narcissism complex, and Caroline), and you are correct in none of the names referenced being spoken in-game (Per the Half Life Wikia):

Interestingly, neither the full name of GLaDOS or her acronym has ever been pronounced by any characters in the games. (Except for Cave Johnson in the DLC Perpetual Testing Initiative, where he says "we are cancelling the Genetic Lifeform and Disc Operating System initiative.") The only instances of her name's presence was through her captions, the acronym spotted on her disc generators in Portal, and the door within the trap leading to the Central AI Chamber in Portal 2.

However, GLaDOS says "Chell" exactly one time...in an audioclip never used in the final version of Portal 2:

Additionally, in the credits song of Portal 1, GLaDOS clearly sings "I'm so GLaD I'm not you" with the lyrics having that exact capitalization, also hinting towards the name GLaDOS.

The names are probably simply not mentioned for immersion reasons--the player is simply supposed to be Chell, and how often do friends call you by your name in one-on-one conversation? It's less clear why GLaDOS and Wheatley never speak their names (and they sure don't), but if you leave subtitles on it's quite clear what the character's canon names are.

  • Well... Wheatley is scared of "her".

Just to add to the existing answers, the credits in Portal and Portal 2 do actually give explicit names.

From Portal:



From Portal 2:

GlaDOS Wheatley


In Portal 2, when you're in the employee day care, the mutant potato science project has "by Chell" written on it. Whether this is the same Chell is up for debate, but this points to the possibility that Chell is the daughter of an Aperture employee.


In one of the Perpetual Testing Initiative tests, Cave says "the Genetic Lifeform and Disk Operating System" (GLaDOS), but other than that, GLaDOS' name is not spoken in either the shortened acronym form or in full (by characters in the game). Her name can, however be found in the second game on the fake door in Chapter 5 that you see just before entering GLaDOS' chamber and in an information icon if you wait long enough before picking her up at the end of Chapter 6. Wheatley says his name once, and Chell's name can be found in the corner of one of the "Bring Your Daughter to Work Day" projects. Both GLaDOS and Wheatley's names can be found if you turn the closed captions on, and all three of them can be seen in the credits and heard spoken if you play through it with developer commentary.


the name chell is from the comic book series "Lab Rats" which also tells the story of Ratman and the talking Companion Cube.


GLaDOS's name is not spoken in game but it is in text (aside from closed captioning). The sign on the fake door before GLaDOS drops you into the moving glass room says "GLaDOS Emergency Shutdown and Cake Dispensary"


At one point wheatly after his takeover does at one point sarcastically mention how "scared" he is of "chell and a potato"


Has nobody seen the ending scene of Portal 1? When you are being dragged away by something, and Aperture Science is burning, the pieces clearly say "GLaDOS". And on Portal 2 later on, you see Aperture Laboratories crossed out and says Wheatley Laboratories instead. It also mentions Chell in the ending credits/song.

  • Now read the question again. I don't see how "it's written there" answers the question about GLaDOS being spoken in the game. Also OP knows about Wheatley Labs. The question is about Wheatley introducing himself.
