Willow Rosenberg is a powerful witch known for fighting supernatural forces in Sunnydale, CA. Although she has always been curious about witchcraft and has a natural talent for it, she doesn’t really begin exploring it fully until she joins a Wiccan group in college. She quickly becomes very powerful, but performing spells gives her headaches, nosebleeds and turns her eyes black. She begins to lose control of her power and nearly destroys the world. Luckily, a friend of hers talks her out of it. She is still active, but her whereabouts is unknown.
She was portrayed by actress Alyson Hannigon on the television show Buffy the Vampire Slayer (1997-2003).
