Lucifer

Lucifer is featured as a boss in Kingdom Hearts Birth by Sleep. In the game, Lucifer is on a self-assigned mission to keep Ventus and the mice from collecting materials for Cinderella's ball gown, just as he did in the classic film Cinderella.

Kingdom Hearts Birth By Sleep
When Ventus comes to Castle of Dreams, he quickly befriends Jaq, one of Cinderella's mouse companions. On a mission to collect materials for the girl's ball gown, he runs into Lucifer, and a fight ensues. Ven ultimately defeats Lucifer and the evil cat runs away.

Appearance
Lucifer is a fat cat with dark brown fur covering most of his body. The fur on his belly, his paws, and the tip of his tail is tan. The fur on his head is ruffled and black. Lucifer's eyes are green and his sclera are yellow, while his nose is pink. He has two whiskers on either side of his upper lip.

Origin
Lucifer is a ferocious cat from the 1950 Disney film, "Cinderella". A nemesis to Cinderella's mice friends and the other animals living on Lady Tremaine's estate, he is pampered and praised by the elderly lady. While the two stepsisters and the wicked stepmother fail to realize Lucifer's evils, he never manages to avoid the protective and watchful eyes of one person, Cinderella herself. She has a secret weapon used for dealing with the devious cat, however; her loyal dog Bruno. At the film's climax, he again tries to catch both Jaq and Gus while they are trying to free Cinderella from her locked room, but the birds see this and summon Bruno, who rushes to the mice's rescue and scares Lucifer out of the house.
