First Appearance Wonder Woman

Dr. Isabel Maru was an expert of poisons and toxins. She worked for the Central Powers during World War I, known by some under the name of Doctor Poison.


Dr. Maru (aka Dr. Poison) presents a gift to General Ludendorff: A new formula she has developed, which when inhaled, gives Ludendorff enhanced strength and aggression, for a limited time. The effect of the gas makes his skin translucent and crackling with energy, and his eyes black. Wonder Woman battles the enhanced Ludendorff and ultimately slays him. It's then that the real Ares appears and reveals a twisted secret: that he came to Dr. Maru and "whispered" in her ear, influencing her with the secret to make the gas that gave Ludendorff his power - in order help deceive Diana into attacking the wrong target. 

Diana and Steve Trevor ultimately stop Dr. Maru and destroy her labs and stockpiles of gas. However, Maru is spared by Diana, and flees the scene while Wonder Woman battles the real Ares.
