Frank Einstein was born Zane Townsend, an agent of the Tri-Eye Agency. Townsend was killed in a car accident, then stitched back together and brought to life by two scientists, Dr. Egon Boiffard and Dr. Gillespie Flem. This resurrection left him amnesiac, and the resurrected John Doe was named after each of Flem and Boiffard's heroes, Frank Sinatra and Albert Einstein The procedure left Frank with supernatural reflexes and a slight degree of precognitive and empathic power, however he remembers nothing about his former life but faint, troubling memories relating to his death. Madman's costume is based on the only thing he can clearly remember: a fascination with a comic book character called Mr. Excitement.
