About Buffy:
Buffy Anne Summers was born in 1981 to the now-divorced Hank and Joyce Summers. As a child, she would pretend to be the superhero Power Girl, which would turn out to be a prophetic choice of alter ego. She was very close to her cousin Celia until Celia died in a hospital, leading Buffy to hate hospitals.
Buffy started attending Hemery High School in Los Angeles, in the fall of 1995. She was elected the equivalent of the May Queen in 1996, and it was also then that she learned from a Watcher named Merrick that she was the Chosen One, the Slayer of vampires. Durring her inital foray into Slayerhood, Merrick was killed and she burned down the school gymnasium. Her parents--who had been having marital difficulties for some time--finalized their divorce that same year.
Her mother gained costody of Buffy in the divorce and the pair moved to a house at 1630 Revello Drive in Sunnydale, California, and Buffy enrolled as a sophomore at Sunnydale High School. Reluctantly at first, she again took up her duties as the Slayer, with Rupert Giles as her new Watcher.
