Rikki Chadwick

Rikki's a rebellious risk-taker, so it's no surprise that she's thrilled to develop special powers. Although she's wilder than Cleo and Emma, Rikki is more than just a troublemaker. She's always willing to stand up for her friends, and she encourages the other girls to embrace their newfound powers.

Special power: Rikki has the ability to heat water with her mind -- a dangerous power for someone with such a hot temper.
