A tall, thin and scruffy red, white, gold and black lightening-striped cat who breaks every law, even that of gravity. He disrupts the Ball, kidnaps Old Deuteronomy and tries to do the same with Demeter. He is the Napoleon of crime whose agents include Griddlebone, Mungojerrie and Rumpleteazer (the latter according to the Original London Cast recording). Macavity was based on Moriarty, the villain in Sherlock Holmes. On Broadway he was Old Deuteronomy's son and symbolised power.
