Rupert Giles is a fictional character created by Joss Whedon for the television series Buffy the Vampire Slayer. The character is portrayed by Anthony Stewart Head. He serves as Buffy Summers' mentor and surrogate father figure. The character proved popular with viewers, and Head's performance in the role was well received. Following Buffy '​s run, Whedon intended to launch a television spin-off focused on the character, but rights issues prevented the project from developing. Outside of the television series, the character has appeared substantially in Expanded Universe material such as novels, comic books, and short stories. Giles's primary role in the series is Watcher to Buffy in her capacity as vampire Slayer; he is in the employ of the Watchers' Council, a British organization that attempts to oversee the actions of the Slayer. From youth, Giles was expected to follow the family tradition and become a Watcher, though as a teenager and young adult he rebelled, dropping out of Oxford University to experiment in dark magic and the rock music scene, until a bereavement brought him to his senses.
