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 and saved his life when his bike went out of control(as seen in Season One's The Day Of The Rose). However, she grew over it quickly and began using him like her sisters did. Darcy has demonstrated the power of confusion (as seen in Season One's The Day Of The Rose). She also has been seen to have hypnotic powers and in " Little big shots" Darcy is ticklish.
