Kristin Bauer will ditch her fangs to play wicked Maleficent on "Once Upon a Time". The Pamela Swynford De Beaufort of "True Blood" has landed a one-episode guest spot on the new series that will debut on Sunday, October 23, a spokesperson for ABC has confirmed.

Sharing her excitement about the new role, Bauer tweeted on Tuesday, September 27, "Packing for Vancouver - to shoot #OnceUponaTime - new fantastical TV show." She further teased, "Just got to Vancouver & had fantastical wardrobe fitting! Not sure Maleficent's future But the present is pretty fun!"

According to TVLine, the role of the evil witch from "Sleeping Beauty" was originally given to Paula Marshall ("Californication"). However, it was reported that "producers decided to go in a different direction." Bauer will appear in the second episode that will air on October 30.

Coming from "Lost" writers Edward Kitsis and Adam Horowitz, "Once Upon a Time" is a fantasy family drama that centers its story on Emma Swan who's been on her own ever since she was abandoned as a baby.
