Dr. Octagon is one of Kool Keith's most popular personas. Octagon first appeared on the 1996 debut album, "Dr. Octagonecologyst". This alter-ego examines the impersonal, delusional, and authoritarian aspects of institutions using hospitals and psych wards as the main metaphor. Keith performed and released two albums under this alias until the character was murdered by another persona called "Dr. Dooom" in 1999. As explained by the artist, Dr. Octagon is an extraterrestrial surgeon from Jupiter who uses space technology and primitive tools to perform medical procedures on his patients. Octagon also practices as an orthopedic gynecologist and seduces his female patients and nurses.
