Feminum

Feminum is a fictional element featured in the 1975 Wonder Woman television series. It technically first appeared in the pilot episode of the show, "The New Original Wonder Woman", but was not identified by name until the season one episode, "The Feminum Mystique".

Feminum is a metallic mineral found only on Paradise Island. It is extremely durable and can deflect high impact projectiles such as bullets. The magic bracelets, known in the comic books as the Bracelets of Submission, worn by Wonder Woman is composed of this metal. Princess Diana's younger sister, Drusilla, also wears bracelets composed of Feminum.

Bracelets made of Feminum are required for the Amazonian ritual known as Bullets and Bracelets.
