Watcher

A Watcher is a member of a secret organization, the Watchers' Council, devoted to tracking and combatting malevolent supernatural entities (and particularly vampires), primarily by locating individuals with the talents required to fight such beings and win. More specifically, Watchers are assigned to Vampire Slayers, girls that are part of a succession of mythically powered individuals who are destined to face said foes. Upon a Slayer's demise, her powers are transferred unto a new girl, who is then assigned a Watcher herself. The Watcher's Council trains new Watchers in a private school of some kind. Wesley was Head Boy during his time at the Watcher's Academy.
