Mark Horley was a criminologist whose great intellect drove him to crime to satisfy his ego. In his lab, he created a formula which changed him, in a Dr. Jekyll and Mr. Hyde fashion, into a hideous monster, terrorizing the streets at night. By day he worked with the police investigating his own crimes. The Black Hood caught on to Horley’s dual lifestyle, and when confronted, the Monster took poison capsules and died.
