Kitsis: "In our world, Maleficient is the Evil Queen's oldest friend - and someone she wishes would just drop dead. That's what happens when evil befriends evil." Horowtiz: "To go to toe to toe with our Evil Queen we needed an iconic character - which led us to introduce Maleficient. And as huge fans of Kristin's we couldn't imagine anyone better to come in and bring her to life."
The show will also introduce the Blind Witch from the Hansel and Gretel story, and here are some spoilers about the character:
"She lives in a gingerbread house and likes to dine on small children. She's incredibly scary and frightening. Although blind, she's also intense, strong, and calculating - no pushover, even for a grown man. Rather than hunting her prey (children), she uses her gingerbread house to lure unsuspecting young wanderers to her, only springing into action once they've stepped squarely into her trap."
