Nyancy is shown to be a human Asian girl with black-purple hair in the style of a long ponytail with a pink bow on her head that resembles cat ears, and four purple lines on her face that resemble whiskers. She also wears glasses, sports a white and light purple dress with pink tights, light purple sneakers, a cat bell on her neck, and cat paw-like gloves.
When Nyancy activates her powers, her pupils become slitted like a cat's.
She is very obsessed with felines, sometimes even acting like them, such as meowing and purring like a cat, specially while talking to and controlling them.
