Robert Harrison was the assistant to explorer Dr. Roberts and was engaged to the doctor's daughter Jean. While exploring Tibet, Robert discovered a lost treasure. However, their guide Singa sought to claim the treasure for himself and injected Harrison with a mixture of rare herbs, transforming him into a werewolf. Unaware of this and unsure how to cure him, Dr. Roberts brought Harrison back to the United States and kept his transformation secret from Jean, telling her that Harrison was staying in Tibet for another year or two.
Roberts sought the aid of Doctor Lin to cure Harrison. When Lin proved to be unable to do so, he recognized the costume vigilante known as the Angel as one of his former medical students and released Harrison in the hopes that the Angel would find a means to cure him. The Angel captured Harrison and indeed determined a means to cure him; however, he was attacked by Singa who turned himself into a werewolf. The Angel slew Singa and restored Harrison to human form, and Harrison told everyone gathered why Singa transformed him into a werewolf.
