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 outside of Japan) Famicom game of the same name.
He was voiced by Ikuya Sawaki in the Japanese version and Dean Hagopian in the English version.
