GLaDOS is the massive supercomputer of Apeture Science. GLaDOS is one of the only 2 main characters in the first Portal, and is still a main character in Portal 2. GLaDOS had different cores plugged into the sides of her. The last
core was plugged in
late, but this was because she flooded the Enrichment Centre with a deadly nerotoxin, the
core was the Morality
core (Followed on from her curisoty, anger and inteligence cores) and was supposed to
stop her from flooding the enrichment centre. When Chell meets GLaDOS, GLaDOS mentions a suprise, but instead of the suprise (most likely going to be nerotoxin) her morality
core falls out. Trying to tell Chell to leave it
alone, Chell incinerates it, and she starts flooding the enrichment centre again. GLaDOS stands for Genetic Lifeform and Disk Operating System. GLaDOS also was killed by Chell, but
re-awakened by Wheatly and Chell a later few thousand years on, and want to continue testing.
GLaDOS's Morality
core causes her to
lie.
Example:
GLaDOS: You are doing, very well!
GLaDOS: You will be
baked, and then, there will be cake.
