The series' antagonist is initially Lady Kale (voiced by Corinne Orr, who also voiced Kale's good sister Queen Anya), Gwen's wicked aunt. Kale has become an "outlaw princess" after having been banished by Merlin for her earlier plots against him and Anya, and now uses magic for evil through the Dark Stone in her ambition to become the absolute ruler of Avalon. She is aided by her animals: Grimm the dragon (voiced by Peter Fernandez) and a duo of small dragon-weasel creatures named Rufus and Twig (voiced by John Beach and Henry Mandell, respectively). The prime villain of the second season is Morgana (voiced by Deborah Allison), with a revived Kale being reduced to her very insubordinate sidekick.
