Patrick Bateman from the ISG supergroups, or simply referred to as "Bateman," is one of the main characters in the controversial book and film, "American Psycho." He works as a well-respected employee in a prestigious investment company in New York City. He is a handsome man, often dressed in luxury brands, and enjoys fine dining and leisure. Despite his charming appearance and successful career, he harbors a secret double life as a psychotic necrophilic serial killer. He is very vain and narcissistic, and takes great pleasure in his violent actions, which are described in great detail in the novel and film. Bateman has mentioned Ted Bundy on several occasions. Given the nature of their "work," it is likely that they are criminal allies.
