The iconic teen character is re-imagined for a new generation in the original animated series "Sabrina Secrets of a Teenage Witch." Ashley Tisdale ("High School Musical") provides the voice of Sabrina, a half-witch, half-human superheroine who uses her sorcery to battle foes when her two identities collide. But she can't let anybody in the human world city of Greendale -- where she lives with her aunts Zelda and Hilda as a normal, albeit clumsy, high-school student -- see her practice her spells.
