Cindy wears a blue shirt & lighter blue pants as casual clothes on one point, and a red dress with a black strip for formal parties. She has seismo-boots like her daughter Mandy, only hers is black and red. She also wore blue & black seismo-boots on one occasion in the same episode. She has a normal build, and shoulder-length black hair.
Cindy is evil, like every other villain, and expects her daughter Mandy to follow the same path. She forbids Mandy from dating Eric because he is good, but she loves her and gets worried about her.
Not much is known about Cindy, not even about her husband, if she still even has one.
