Lucifer (ルシファー) is the chubby, black-furred pet cat of Lady Tremaine in Disney's Cinderella (1950), designed by animator Ward Kimball. Spoiled, cunning, and intensely sadistic, his main motivation is tormenting Cinderella and hunting her mouse friends, Jaq and Gus. Despite his clumsy heftiness, he possesses sharp claws and a deviously clever wit.
