History
Dr. Psycho was first seen impersonating a child psychologist named Dr. Charles Stanton at the Adams Junior High School in Boston, Massachusetts by mentally forcing students to improve their grades, while secretly instigating conflict by controlling the minds of Wonder Woman and Hermes to force them to fight and destroy all the people in Boston as his criminal masterpiece. His control was interrupted after being discovered by Helen Andersen who was trying to investigate the secret to the recent success in student grades, before knocking her out and holding her hostage. He used his mental powers to torture Helen by putting nightmares into the mind of her unborn child to drive her insane and kill her along with her baby, but was stopped by Wonder Woman who managed to find Doctor Psycho by reading the memories of Vanessa Kapatelis, a close friend of Wonder Woman who had been affected by Dr. Psycho's mind control. He was knocked out after trying to hypnotize Wonder Woman by pretending to be Dr. Stanton.
