Darcy is a young witch described as the "'Lady of' Darkness", "Queen of Darkness" or the "Queen of Dark Magic". She is a member of the Trix, a trio of witches. She is more calm and competent than her sisters. Devious and manipulative, Darcy uses subtle dark magic and illusions to confuse and control opponents. She is good at discovering weaknesses and exploiting them. It was hinted that she had a crush on Riven, as she remarked that he was cute, saved his life when his bike went out of control, (as seen in The Rose Festival) and went on dates. However, she grew over it quickly and began using him like her sisters did. Darcy has demonstrated the power of confusion. She also has been seen to have hypnotic powers.
