"And that includes you, your "Majesty""

- Cinderella to Lucifer

Lucifer is a supporting antagonist in Disney's 12th full-length animated feature film, Cinderella, and the 2015 live action film of the same name.

Although Lucifer was extremely loyal towards humans, he was monstrous to the many mice that inhabited the home. He also likes to torment Bruno (who hates him) and Cinderella. He was also an obstreperous troublemaker who enjoyed causing mischief.

Lucifer is a henchman of sorts to Lady Tremaine (at least, he views himself as one) - the role of henchman becomes more pronounced in the direct-to-video sequels in which Lady Tremaine gains access to the Fairy Godmother's magic wand and transforms Lucifer into a twisted version of a coachman.

In the first film, he was voiced by the late June Foray, who also played Natasha Fatale, Wheezy, Magica De Spell, and Witch Hazel. In the sequels, he was voiced by Frank Welker.
