Doctor Psycho

He is a telepath with the ability to enter and sometimes shape other people's dreams. Psycho was enlisted by Circe to create disturbing dreams for Wonder Woman's close friend, Vanessa Kapatelis, with the result that Wonder Woman would be forced to separate herself from her closest allies. This was part of a plot intended to leave Wonder Woman isolated and create widespread public fear of her fellow Amazons. Psycho later helps warp Kapatelis' damaged psyche to turn her into the new Silver Swan.

Dr. Psycho's plans are foiled and he subsequently spends some time as a patient in a mental facility, confined to a padded room and a straitjacket. Several members of the time-lost Legion of Super-Heroes were in telepathic range. When Saturn Girlmentally shouts for a lost member, this awakened Dr. Psycho enough for him to attack several staff members and flee. The call brought him to the Legion, whom he also attacks.
