Doctor Psycho

Doctor Psycho is a fictional character appearing in DC Comics publications and related media, commonly as a recurring adversary of the superhero Wonder Woman. Doctor Psycho first appears in Wonder Woman #5 (1943), written by Wonder Woman creator William Moulton Marston. Doctor Psycho has been one of Wonder Woman's most persistent enemies, reappearing throughout the Golden, Silver, Bronze, and Modern Age of Comics. Over the decades, Doctor Psycho has undergone several minor updates as comics continuities have shifted and evolved, though his distinctive physical appearance has remained largely faithful to artist Harry G. Peter's original 1943 design.
