The Computers

The Computers is a collective term used to refer to the three supercomputers moderating the Grand Combat. They are:
 * The well-meaning, rational Deep Thought
 * The cynical, cruel GLaDOS
 * and the terrifying, emotionless HAL9000

Deep Thought
Deep thought is the "friendliest" of the computers, complimenting fighters on achieving their goals without excessive violence. Deep Thought originated in The Hitchhiker's Guide to the Galaxy series.

GLaDOS
Sadistic and insulting, GLaDOS considers organic life below her, yet necessary to complete her studies. GLaDOS originated in the Portal video game series.

HAL9000
The HAL9000-series supercomputers are driven by logic above all else, which makes them cold and impersonal. The HAL9000 line is native to Arthur C. Clarke's Space Odyssey series.
