3. Doctor Psycho
Doctor Psycho is another mind-controlling telepath who first appeared way back in 1943 in Wonder Woman #5. In addition to his telepathy, he also has the ability to cast frighteningly realistic illusions and to enter and reshape the dreams of other individuals. He is a very creepy-looking character who is very small (Peter Dinklage would make a great Doctor Psycho if he wasn't already contracted to Marvel) and is often depicted as resembling a ventriloquist's dummy. He has a misogynistic obsession with beautiful women and is generally considered to be clinically insane. Doctor Psycho has often worked in conjunction with other supervillains (such as Circe, who has amped his powers on occasions) in his attempts to defeat Wonder Woman, so if he was to appear on the big screen there would be a strong possibility that he wouldn't be alone.
