Lucifer

Unreleased

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

Story
When Ventus comes to Castle of Dreams, he quickly befriends Jaq, one of Cinderella's mouse compainions. On a mission to collect materials for the girl's ball gown, he runs into Lucifer, and a fight ensues. Ultimately, Lucifer realizes that he is no match for Ventus's Keyblade and friendship with Jaq, and flees the scene.

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.
