Evil Zizi Schwarz (Bettina Busch) is a doppelganger in the 1967 Italian action film "The Three Fantastic Supermen", which was originally termed "I fantastici 3 Supermen". It was the first of three Supermen films.
Zizi Schwarz is duplicated by a cloning machine known as the universal reproducer. This is the creation of Wilfred Gottlieb (Jochen Brockmann), who is flooding the market with fake currency, gold, and precious jewels. Gottlieb is aided by his loyal henchwomen, Madame Astrid Countess of Boideux (Sabine Sun) and Diana (Rosella Bergamonti).
After using Professor Schwarz (Carlo Temberlani) to perfect the process of the machine, Gottlieb was able to duplicate people. The evil Zizi was the duplicate of Professor's daughter.
The original Zizi was the lover of Tony (Tony Kendall), who was one of the three Supermen. She was left locked in a freezer along with several of the children from Gottlieb's school. He was cloning the children to do his bidding.
The evil Zizi met Tony and the other two Supermen at the base and told them to follow her and she would lead them safely out. However, Tony noticed that Zizi's beauty mark was on the wrong wrist. Therefore, he tossed her onto an electric floor, and began to be electrocuted. After screaming for several seconds, her body disintegrated and was left with a pile of jewels.
