High Quality Content by WIKIPEDIA articles! A Slayer, in the fictional Buffyverse established by Buffy and Angel, is a young female bestowed with mystical powers that originate from the essence of a pure-demon, which gives her superhuman senses, strength, speed, endurance, agility, and healing in the fight against forces of darkness. She occasionally receives prophetic dreams in the few hours that she sleeps. The Prophecy of the slayer states, "Into each generation a Slayer is born: one girl in all the world, a chosen one. She alone will wield the strength and skill to fight the vampires, demons, and the forces of darkness; to stop the spread of their evil and the swell of their numbers. She is the Slayer."
