Doctor Poison (DC Comics)

Princess Maru, a genius chemist and chief of the Nazi poison division, led an Axis spy ring. Introduced in National Periodicals' Sensation Comics #2 by William Moulton Marston and H. G. Peters, as Dr. Poison, she wore an outfit that made her look like a man while spreading a drug that made soldiers disobey orders. Caught, she escaped to work for the Japanese, grounding Allied planes in China with a green fog that destroyed engines. Caught again, she returned only one last time after WWII, but left the matter of her being a princess a mystery.
