Administrator (Team Fortress 2)

The Administrator (real name Elizabeth; family name unknown), also referred to as the TF Announcer or simply the Announcer, is the CEO of both RED and BLU as well as TF Industries. She is the main antagonist of the Team Fortress Comics and possibly the entire storyline (including the actual online game itself). She is the source of the mysterious, disembodied voice that issues commands and announces vital events during matches. An aged and thoroughly evil mastermind of a woman, the Administrator possesses both a piercing gaze and the sort of voice that commands total and unwavering obedience...or else. Her general demeanor tends towards either slight anger or various stages of bitter disappointment.

Her appearance and personality are a reference to Cruella de Vil.

Roles and Duties
The Announcer wields considerable influence and power. Once thought  to be the owner of both the RED and BLU Corporations, it has since revealed that Blutarch and Redmond Mann are both still alive by Radigan Conagher´s Life extender machines. Despite their continued existence, neither of Mann brothers seem capable of handling the affairs of their respective companies; so for all intents and purposes the Announcer can be said to control them. By extension, this grants her control over every major government on the planet. She tends to keep her operations top secret, manipulating events from behind the scenes. Any development that may chance unwanted attention is swiftly terminated whit extreme prejudice.
