Dr. Psycho

Few villains have haunted the pages of Wonder Woman's world quite like Dr. Psycho, a Silver Age menace who first slithered into DC continuity in 1966, conjured by the legendary team of Robert Kanigher and Ross Andru. Across nearly six decades of publication, this unsettling figure has kept dangerous company — squaring off against Wonder Woman and Princess Diana herself, crossing paths with the likes of The Cheetah and even Superman. His appearances span Wonder Woman and beyond, and the sheer longevity of his presence in DC's catalog marks him as one of the Amazon's most persistently compelling adversaries — a dark fixture in her rogues' gallery that collectors and fans keep returning to.
