Drusilla is a major antagonist of the TV series, Buffy the Vampire Slayer and one of the few vampires that have managed to battle Buffy and her crew over a prolonged period of time while living to menace them another day. There is no doubt she owes some of her survivability to her tendency towards staying in the shadows rather than engage in outright assaults. Despite her madness, she is a very clever and murderous woman who is capable of formulating many plans - often of surprising complexity or merit.
Drusilla is not, however, a stable villain - in fact she is psychotic even by the standards of vampires, this is due to Drusilla's tragic origin in which Angelus killed her family and tortured her to madness before finally making her into a vampire - as he viewed her as a "masterpiece" of his own design. Drusilla is one of the "Big Bads" of Season 2, alongside Angelus.
Drusilla was born in the mid-19th century in London, to a devoutly Christian family. She grew up to be innocent, chaste and devout, but was plagued by a precognitive ability to see the future. Her mother had her suppress these powers, claiming that the visions were from the devil.
One night in 1860, she caught the attention of the vampire Darla, who recognized her prophetic abilities. She brought her to the attention of her lover, the ruthless vampire Angelus. Angelus became obsessed with her, and began mentally torturing her in an effort to create a "masterpiece" of torture. Angelus visited countless atrocities upon her, the worst of which were massacring her entire family before her eyes, only to allow her to escape and join a coven. He then proceeded to massacre her new sisters in the same way, on the day she was to take her vows. Drusilla's sanity was lost that day, rendering her insane. Angelus, in order to preserve his "masterpiece" for all eternity, turned Drusilla into a vampire.For the next twenty years, Drusilla joined her new family; Angelus and Darla, in wreaking havoc across Europe. Feeling lonely due to having to share Angelus with Darla, she sired a young poet named William, who would later take the nom de guerre Spike, she made a new addition to the "family." Spike was completely and utterly devoted to and in love with Drusilla, yet she continued to maintain a sexual relationship with Angelus, much to Spike's displeasure, leading to a rivalry between Spike and Angelus.
After Angelus' soul was forcibly restored by a gypsy spell, leading him to be excluded from their company, Drusilla and Spike took their leave of Darla, journeying on their own for the next 100 years. In the late 1990's, Drusilla was kidnapped and tortured by a human inquisitor in Prague, which left her severely weakened. Spike took her to Sunnydale, the location of a Hellmouth, hoping that its demonic energies would help heal her. Unbeknownst to them, Sunnydale was home to the latest Slayer: Buffy Summers, as well as the now redeemed Angelus, using the name Angel, who fought by her side. Drusilla and Spike would frequently clash with them.
Spike eventually found a way to restore Drusilla to health, in a ritual sapping Angel's life-force to restore hers. The ritual was succesful in curing Drusilla, but the intervention of Buffy left Spike crippled, an allowed Angel to escape with his life. Shortly thereafter, Angel's soul was once again lost, restoring him to his former evil self. He re-joined Spike and Drusilla, much to their pleasure, though Spike would quickly grow to resent Angel once again, especially when he resumed his sexual relationship with Drusilla.
Angel concocted a plan to send the entire Earth into a Hell-Dimension, and Drusilla gladly aided him. Spike however, betrayed the two, siding with Buffy in exchange for his and Drusilla's free passage. Spike wanted things to go back to the way they were, and enjoyed Earth too much to have it be destroyed. Angel was defeated and sent to Hell (though he would eventually return, with his soul restored) and Spike took Drusilla and left the country.
Drusilla became sickened and disillusioned with Spike however, and broke up with him, starting a relationship with a Chaos Demon.
When the evil law firm Wolfram & Hart brought her grandsire Darla back to life to torture the once again heroic Angel, Drusilla was called in to make Darla a vampire once again. Drusilla and Darla resumed their acquaintance and hunting. They targetted Wolfram & Hart, slaughtering the higher brass of the company with Angel's blessing. They began recruiting demons to turn Los Angeles into their own "playground". but Angel, driven to depression and violence by his failure to save them, set them both on fire.
Drusilla returned to Sunnydale to lick her wounds and convince Spike to return with her to attempt to restore their old "family". By this time however, Spike had fallen in love with Buffy and tried to kill Drusilla in order to prove his love. Heartbroken by Spike betraying her once again, Drusilla left, and thus remained at large.
Before becoming a vampire, Drusilla was chaste, innocent, kind-hearted and devoutly Christian.
After being driven to insanity and turned into a vampire by Angelus, her personality changed drastically. She became unstable and unpredictable, with a love for victimizing the weak and innocent, especially children. She also became very infantile, often behaving like a little girl and had a penchant for playing with dolls. She was unusually loving for a vampire, making her fellow vampires into a surrogate family, with Angelus as her "father," Darla as her "grandmother," and Spike as her lover, though these roles often overlapped (she maintained a romantic and sexual relationship with Angelus, and had at least one sexual encounter with Darla).
Because of her insanity, she often spoke in riddles and babbled nonsense, though she was capable of carrying on normal conversations, particularly with Spike. She is very fond animals and plants, although she is terrible at caring for them. In Sunnydale, Angelus gave her a garden to tend to, to her immense delight.
