The AI Director, or simply The Director or AID, is a relatively simplistic  who possesses no sentience, following strict programming. Along with and, The Director is one of the.

Appearance
Since he exists outside the universe, the Director has never been seen in person.

Personality
The Director's true personality is hidden behind the people he controls. They keep their own personality but will turn more aggressive when aggravated or certain conditions trigger The Director's aggression.

Policies

 * Never The Director
 * The Director's programming is absolute. Until he gains sentience, he may never disobey the rules embedded into his existence.
 * Adaptive Difficulty
 * The Director can change the difficulty he is placing on Carriers based on two criteria. When the Director deems it time to increase difficulty, he will spawn more aggressive Infected. However, he cannot spawn anything where anyone can see. So Skynet, who is present everywhere, is capable of choosing when and round about where the Director can spawn his Infected.
 * Ongoing Challenge
 * The Director monitors how all Carriers are doing and increases the difficulty for teams doing well and decreases for teams not doing well. He also gives extra help and advice to new Carriers but will eventually stop helping when the Carrier is experienced enough.
 * The Rude and Reckless
 * The Director rewards teamwork with extra help but punishes anti-team play harshly, such as friendly fire, straying away from the rest of the team and idling. All of these may cause The Director to attack only the offending Carrier for a short period before he switches back to attacking all Carriers again.
 * The Anti-Cheat
 * The worst offence in The Director's programming is cheating, which he will attempt to deal with above everything else against both Infected and Carriers. He considers cheating to be anything that the being would not be able to do in a non-digital world. However, since The Director cannot tell what beings can do what in non-digital world until the world is turned digital, both Yggdrasil and Skynet accidentally bent this rule in the very brief moment where the Director had not yet connected with Yggdrasil's digitalisation. Thus The Director considers Yggdrasil's and Skynet's control over others to be normal.

Powers
AI Powers
 * The Director's AI powers are limited to items he can control but in those cases his powers are the strongest in the universe, surpassing even Skynet, who is considered a mere player in the eyes of The Director and cannot override his abilities.


 * Infectious Control
 * The Director controls the spread of . Anyone infected by Green Flu but not deceased is controllable by the Director. This means the undead Infected are not under The Director's control. This allows The Director to control human beings as long as they are not immune, Carriers or sealed off from the Flu.


 * The Director can only communicate through others.
