Well, wonder no more as here's a quick collection of a few of her villains (represented on the cover of Wonder Woman #323 of February, 1985, by Ed Barreto)....
....Dr. Psycho, Silver Swan, Angle Man and the Cheetah.
The doctor was an evil little man with the ability to manipulate the mind, fighting Wonder Woman in Wonder Woman #160, #163, #165, #168 and #170, then taking a break to come back with Wonder Woman #288 to #290 before the team-up of Wonder Woman villains in Wonder Woman #323 (February, 1985).
Silver Swan worked with Dr. Psycho (and his alter ego of Captain Wonder) in Wonder Woman #288 to #290, before returning in Wonder Woman #323 (February, 1985).
....though they all did come back.
