Zuul is one of Gozer's terror dog goons who plotted to resurrect her master and destroy the universe. She assumed human form to trick Peter Venkman into sleeping with her so that she may get a chance to pry out all of his information to be able to get Gozer out of the other side. Zuul was eventually destroyed by the Ghostbusters in the final battle. Bowser later resurrected Zuul by using Kimberly's body as a vessel so that he may free his brother, the dark lord....Maligore!!!!
