In the original Androzons series Dr. Hilda Van Burden is a mysterious woman from the far future who created the Evil Cat Sisters (E.C.S.) to try and conquer the present but came against fierce opposition from the titular Androzons, who protected the world from Burden and her creations in a largely comedy-based series that continues to this day. However when Burden was "crossed over" with the Extinctioners universe some of her origins and personality changed, though the basic formula of her being the true commander of the E.C.S. and the archenemy of the Androzons remains.
