Dark Magician Girl, known as Black Magician Girl in the Japanese version, is often used as a card in many of Yugi's Duels, but has also appeared as a monster spirit on various occasions. Dark Magician Girl's outfit is very similar to that of the Dark Magician, except that it is mainly blue and pink with a few touches of yellow. She has blond hair, green eyes, and wields a wand that matches her outfit. In English versions of the anime and cards, her bust is reduced by erasing cleavage lines and her hexagram is replaced with a red jewel.

Her outfit is composed of an off-the-shoulders garment that extends to her mid-thighs and ends up as a skirt. It is colored blue, with pink trimmings and a few touches of yellow. Also, her hat is pointed, like the Dark Magician's, except it is also blue, along with pink rings and a pink spiral on one side. She also wears boots reaching halfway up her thighs, and her wand,which is colored blue,has a spiral which is similar to the one on her hat, except that it is yellow. She also wears optional pink and blue gauntlets. Her most prominent features are the faint pink markings on her cheeks.

In the original manga, her appearance during the Millennium World arc had tanned skin.
