 In the sitcom, Zelda was blonde and a down-to-earth scientist who tries to keep Sabrina and Hilda out of trouble.As a stark contrast to early comic portrayals, she insists that Sabrina only use her magic for good.As a witch, her magical abilities often manifested as a stream of violet magical particles (similar to Sabrina's golden red magical sparkles) whenever she would transfigure an object or being, conjure an object or teleport herself from one place to another.
