Superia is a Marvel comics super-villain who first appeared in Captain America Vol.1 387.
Superia is a scientific genius who follows a path of ultra-feminism. Many of the foundations for her point of view came about after she constructed a time-probe and sent it into the 23rd century, where it obtained a history book. From the book, Superia learned of the future of Femizonia, a powerful nation state ruled by the women of that future, and of how the men of that era were treated as inferiors. Her research indicated that she was the ancestor of Thundra, the Femizons' most famous warrior and ruler. Although the Femizons' world was an alternate future, Superia became determined to bring about the nation of Femizonia within her lifetime.
