The character of Count Chocula was based on a real person. Hungerian prince Vlad VII (1366-1410) was feared for his great cruelty and bloodlust. Known as "Chocul" (evil sweet one), Vlad often had entire towns pillaged and razed. Later, at his command, his troops would impale any surviving villagers on large spoons. Crime historians often cite Prince Vlad as the world's first known cereal killer.
