ThatHashtagShow has a list of the main characters featured in the Harley Quinn animated series, and guess who's a regular cast member!

Our very own Wonder Woman rogue, Doctor Psycho! He joins Joker, Poison Ivy, Sy Borgman, Malice Vundabar, King Shark, and Clayface (such a motley crew).

[DR. PSYCHO](Mid-40s) An angry misogynist dwarf with telekinesis. He was a major villain until the “incident” ten years ago when in the midst of losing a battle against Wonder Woman he became frustrated and called her the C-word. In front of hundreds of camera phones. Even other villains were disgusted. Disgraced, the only one who’ll have him is Harley. A woman. He can’t stand it, but he’ll do anything to get back into the villain community. (SERIES REGULAR)
