The youngest of the royal family, who can move the elements and has never once been asked what she wants.
Crystal is Medusa’s sister and the youngest member of the royal family, able to control the elements. Isabelle Cornish plays her.
She is the one member of the family who is treated as a child by everybody including the script, and the series is at its most interesting when she stops accepting that. Lockjaw, the teleporting dog, is hers, and is the thing most people remember about the show.
