Superia (Dr. Deidre Wentworth) is a supervillain and criminal scientist appearing in American comic books published by Marvel Comics. Publication history She first appeared in Captain America #387 (1991) and was created by writer Mark Gruenwald and artist Rik Levins. Fictional character biography Little is known of the past of the woman known as Superia, but she was first seen where she and a small army of female supervillains plotted to sterilize all other women in the world, making their reproductive capabilities valuable beyond measure. She was initially inspired to use her scientific knowledge to conquer the world when she discovered, via use of a "time probe", that a descendant of hers, Thundra, would rule the world-spanning matriarchy of the "Femizons". Her plan was thwarted by Captain America and his allies (Paladin, Diamondback, Asp and Black Mamba). She later appeared alongside a much smaller group of Femizons, consisting of Blackbird, Iron Maiden, Nightshade and Snapdragon. This group fought against the criminal scientists of AIM, and were defeated, thanks in part to former Femizon M.O.D.A.M. Superia was saved from certain death by Captain America. Superia again appeared as "Dr. Deidre Wentworth", and gave a young woman named Cathy Webster superhuman physical traits and subliminal performance-boosting messages. These messages also bound Webster (now called Free Spirit) to Superia's control, though Webster was quickly freed. After a failed negotiation with the Baroness Zemo, she convinced Diamondback to join her as penance for having killed her former lieutenant Snapdragon. Superia and Diamondback resurfaced soon after, when Superia was convinced to give Captain America a treatment and cure to reverse a paralytic effect resulting from the serum that had given him his powers. The three of them, alongside other allies of Captain America, attacked AIM to steal its new Cosmic Cube, but were forced to retreat. It was at that time the cure was stolen by the Red Skull, whose mind was at the time living in a body cloned from Captain America, who used the cure on himself, and shot and apparently killed Superia. Having acquired the power of the Cube - although unable to control it directly - Superia sent her knowledge back in time to her younger self, where she was able to use her knowledge to infiltrate A.I.M., create a new heroic identity for herself and some chosen allies, and subsequently infiltrate the Avengers by removing Captain America from history after
