Michael Audrey Myers, (born October 19, 1957) also known as The Shape or The Boogeyman, is the main antagonist of the Halloween franchise. Michael is a silent, deranged serial killer who, at age six, murdered his older sister Judith in cold blood on Halloween night and was incarcerated in a mental institution before breaking out fifteen years later to stalk and murder the residents of his home town in Haddonfield, Illinois almost every year on the night of Halloween.
Due to his ruthless, murderous nature, unsettling, nearly supernatural demeanor and most surprisingly his lack of a tragic or sympathetic backstory to give a clear reason for his actions, Michael is considered to be an embodiment of pure evil. He is both the arch-nemesis of Laurie Strode and Dr. Samuel Loomis.
