Seymour Cheese (aka The Big Cheese) (Kitsunezuka Ko'on-no-Kami in the Japanese version) is the main antagonist from the anime Samurai Pizza Cats. He is the prime minister of Little Tokyo. He is the arch-nemesis of that city and the Pizza Cats, and the supreme commander of the Ninja Crow clan. In the cancelled season 2 of the anime, Dr. Purple was going to replaced the Big Cheese but, it never happened, leaving Dr. Purple's only appearance in the 1991 Japan-only (with later bootlegged as Ninja Cat) Famicom game of the same name.
He was voiced by Ikuya Sawaki in the Japanese version and Dean Hagopian in the English version.
