Witches in Tights

A young boy whose drawings magically come to life is forced to create a drawing that transforms a demon into a super villain. To help the Charmed Ones stop the demon, the boy creates a new drawing that turns Piper, Phoebe and Paige into comic book super heroines. Finally, the villain turns himself into a powerful supervillain and destroys the Charmed Ones super powers. With the help of the boy, the Charmed Ones in turn manage to destroy his super powers and Piper blows him up.
