Rupert Giles () is a fictional character created by Joss Whedon for the television series Buffy the Vampire Slayer. The character was portrayed by Anthony 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 Buffys 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' primary role in the series is Watcher to Buffy (Sarah Michelle Gellar) in her capacity as vampire Slayer; he is in the employ of the Watchers' Council, a British organisation 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. In adulthood, his loyalty to Buffy and her group of friends costs him his job for a time. As the series progresses, Giles increasingly becomes a father figure to Buffy and her friends Willow (Alyson Hannigan) and Xander (Nicholas Brendon). His encyclopedic knowledge, affinity for magic, moderate fighting skills and willingness to kill when necessary make him an asset to Buffy in her fight against the supernatural evils that plague Sunnydale, California.

Following Buffys conclusion in 2003, Whedon intended to continue Giles' story as a spin-off series, Ripper, which he intended to produce with the BBC. The series was to depict Giles in ghost stories set in present-day England, coping with loneliness as well as figurative ghosts from his own chequered past. Over several years Whedon restated his commitment to the project, though announced it would take the form of a one-off TV movie. Despite Head's availability and the BBC's willingness to fund the project, rights issues concerning the character ultimately led to it not developing further. Canonically, the character's story is continued in the comic book Buffy the Vampire Slayer Season Eight (2007–2011) and subsequent stories. The Season Eight sequel Angel & Faith (2011–) heavily features Giles and utilizes ideas and characters from the proposed Ripper spin-off.

Biography Character history Rupert Edmund Giles (most frequently called Giles) was born circa 1955 in England. His family has worked within the Council of Watchers for at least three generations; both his father and grandmother, Edna Giles (née Fairweather), were also Watchers. As a child, Giles dreamt of being either "a fighter pilot or possibly a grocer", but he soon learned that being a Watcher is a calling, much as being a Slayer is, and Rupert's father explained his destiny to him when he was ten years old (revealed in "Never Kill a Boy on the First Date").

Although the Scooby Gang later joked that he wore tweed nappies as a child, Giles was in fact a rebellious youth, rejecting his responsibility as a Watcher and dropping out of Oxford University, where he was studying history, when he was twenty-one. During this time, Giles claimed to be a founding member of Pink Floyd in order to impress girls (although since Pink Floyd was founded in 1965, when Giles would have been around ten years old, it was not a particularly credible claim), and may have delved into criminal activity (he remarks that hot-wiring a car is "like riding a bloody bicycle", and a psychologically younger Giles has no qualms about breaking into a clothing store and attacking a police officer). He is a talented singer and guitar player (as Head was in real life) which the gang discovered, to their astonishment, when they saw him singing "Behind Blue Eyes" by The Who in "Where the Wild Things Are". Spike also saw him singing "Free Bird" by Lynyrd Skynyrd in "The Yoko Factor".

He began to explore dark magic and befriended a group of young people who delved into the dark arts for fun or money: Ethan Rayne, Philip Henry, Dierdre Page, Thomas Sutcliff, and Randall. Giles gained the nickname "Ripper" during this time. Together, the group summoned a demon called Eyghon, who would possess and eventually destroy Randall. Following Randall's death, Ethan and the others failed to exorcise Eyghon, and Giles accepted his destiny of becoming a Watcher. Before becoming a fully-fledged Watcher, he also worked as "the curator of a British museum, maybe the British Museum" as Willow says ("Welcome to the Hellmouth"), although, given the context, she may well have been repeating a rumor that was going around the school.

Sunnydale At the behest of the Watchers' Council, Giles travels to Sunnydale, California, and works as the librarian at the local secondary school. There he meets the current Slayer, Buffy Summers, whom he begins training. The library, a quasi-command centre for Buffy's demon-hunting gang, sits right above the Hellmouth.

As the Watcher, librarian, and general authority figure, Giles often delivers exposition. He is a father figure to Buffy and her friends Xander Harris and Willow Rosenberg, together forming the "core four" of the Scooby Gang. Giles is often portrayed as something of a "straight man" and his "stuffy" Oxford sensibility serves as counterpoint to the stereotypical Southern Californian characters and setting. He makes a "weird cluck-cluck sound with his tongue" when he is angry but is "too English to say anything" ("Faith, Hope & Trick"). He admits to being technophobic, a fact which often brings him into conflict with technopagan and computer science teacher, Jenny Calendar. However, after Jenny aids him in casting the demon Moloch out of the Internet, the pair reach an understanding and begin a romantic relationship. Despite his obvious fear with modern technology, Giles is quite adept with computers, which is required in his occupation as a librarian (season 3 episode "Gingerbread") and likely had received this training while earning his master's degree in library and information science. It was never revealed of which library school Giles attended or whether he had pursued his PhD in this field.

In season 2, Giles' dark side is revealed and his relationship with Jenny deepens. In "The Dark Age", Ethan Rayne comes to Sunnydale to flee the demon Eyghon. Giles ashamedly admits to Buffy that he was responsible for summoning the demon in his youth, and is horrified when Jenny becomes possessed by Eyghon. Although Eyghon is defeated, Jenny takes time to cope with her ordeal, remaining distant from Giles in the meantime. When new Slayer Kendra Young arrives in Sunnydale, Giles shares with her an appreciation for obscure texts, resulting in Buffy nicknaming her the "She-Giles." Giles feels betrayed when Jenny reveals she is actually a member of the Kalderash gypsy clan, sent to keep an eye on Buffy's relationship with the vampire Angel. When Angel loses his soul he reverts to his evil, sadistic alter ego Angelus. Angelus murders Jenny, leaving her corpse for Giles to find in a romantic setting in his apartment ("Passion"), Giles seeks revenge by burning down Angelus' base. Angelus later kidnaps and tortures him, and Drusilla hypnotizes him into thinking she is Jenny so he will reveal how to awake Acathla. Buffy is forced to kill Angel to save the world, despite Willow's restoring his soul, and subsequently leaves Sunnydale.

In season 3, Giles's paternal feelings for Buffy strengthen significantly. He spends the summer desperately following up every clue as to Buffy's whereabouts, and is overjoyed when she finally returns months later. Giles briefly serves as Watcher for Kendra's replacement Slayer, Faith Lehane. The Scoobies are given another disturbing glimpse in Giles' past when, along with every other adult in Sunnydale, he reverts to being a teenager by enchanted band candy supplied by Ethan Rayne. He indulges in theft and vandalism, and makes out with and has sex with Buffy's mother, Joyce Summers. When Buffy keeps Angel's return from hell a secret from the other Scoobies, Giles feels betrayed by her love for the man who tortured him and murdered Jenny, but later agrees to help Angel in "Amends".

As Buffy's Cruciamentum approaches (a brutal tradition of the Watchers' Council in which a depowered Slayer is forced to battle a particularly dangerous vampire using only her wits), Giles struggles to cope with the guilt of betraying Buffy's trust. Despite describing the test as "an archaic exercise in cruelty", he secretly injects Buffy with muscle relaxants and adrenaline suppressors, which weaken her significantly, before finally coming clean when the vampire she is meant to fight escapes. Buffy is disgusted, but is later moved when Giles interferes to save her life and is subsequently dismissed for having a father's love for her. Giles is fired, and replaced with Wesley Wyndam-Pryce, but continues to act as Buffy's unofficial Watcher, proving especially helpful when Wesley turns out to be an incompetent coward. When Buffy briefly finds herself endowed with telepathic powers, she 'hears' her mother remembering that Giles was "like a stevedore" during sex. In a battle with the demonic Mayor of Sunnydale, Giles presses the trigger which destroys the Mayor and Sunnydale High, putting himself out of a job.

In season 4, Giles must cope with unemployment and a growing awareness that Buffy no longer needs him. He continues a sexual relationship with his old friend Olivia. Lacking a sense of purpose, he spends most of his time lounging around his apartment, watching Passions with Spike. He gets depressed, especially when the Scoobies fail to keep him in the loop regarding Buffy's new boyfriend Riley Finn and his membership in the Initiative. In the episode "Something Blue", Giles becomes blind as a result of a faulty spell cast by Willow Rosenberg. When Ethan Rayne casts a spell on Giles which turns him into a Fyarl demon ("A New Man"), he must enlist Spike's help to escape the Initiative and Buffy, which believes him to be a demon who murdered Giles. Buffy, about to kill him, at the last moment recognizes his eyes and "annoyed" expression, and Ethan is taken into custody by the Initiative. In order to defeat the cyber-demonoid Adam, Buffy, Willow, Xander and Giles cast a spell to combine their strength. Giles provides the "mind," and Buffy is able to defeat Adam.

At the beginning of season 5, Giles no longer sees his place in Sunnydale and decides to go back to England, telling no one except Willow, whom he needs to organize the research documents for the Scoobies. He quickly abandons this decision when Buffy asks him to be her Watcher again, confessing that she needs him, both emotionally and in order to discover more about what being a Slayer means.

When the owner of The Magic Box is killed by vampires, Giles is convinced by the shop's high profit margins to buy it, hiring Anya as his overly enthusiastic assistant. Buffy learns that her sister, Dawn Summers, is actually the Key: mystical energy disguised in human form to conceal it from the hell-god Glory. Buffy initially confides only in Giles about Dawn's true nature, and he decides to contact the Watchers' Council for more information about Glory. In "Checkpoint", Quentin Travers tries to coerce Buffy to obey the Council's demands, by threatening to have Giles deported. Buffy stands up to the Council, pointing out that without her there is no need for a Council, and tells them to give her all information concerning Glory and to reinstate Giles as her official Watcher. Travers reluctantly agrees, and leaves.
