Amy Madison is a fictional character on the television series Buffy the Vampire Slayer, portrayed by Elizabeth Anne Allen. The character appears in every season of Buffy except Season Five (during which time the character was stuck in the form of a rat due to a spell cast in Season Three). In the show, Amy is a witch. Although initially a seemingly good-natured individual, Amy gradually begins misusing her magic, eventually becoming an enemy to Willow (Alyson Hannigan) and her friends. In the series' comic book continuation, the character is more of an outright villain.
