Lucifer is the tertiary antagonist of Disney's 1950 animated film, "Cinderella". He has black fur, a toothy grin, and is portrayed as a sneaky, wicked, and cheating predator who loves nothing more than eating mice.

Lucifer is an extremely spoiled, pompous, and gluttonous cat. His only loyalty lies with that of his mistress, Lady Tremaine, who treats him like royalty and acts as his mother figure. He is hostile towards Cinderella, constantly trying to sabotage her plans, and get her into trouble, with the only apparent motive for making her life harder and more miserable, showing he doesn't in the slightest appreciate Cinderella's kind and caring nature. He even seems to dislike Drizella and Anastasia, evidenced by his scowling and covering his ears when the two are bickering over trivial things. Lucifer is also very ambitious and ruthless, going to any lengths to kill the mice that are Cinderella's allies, and is sneaky enough to play the victim when he got Bruno in trouble and manipulated Cinderella into sending him outside.

When Cinderella is later sent to her stepmother's bedroom after being accused of putting mice into the breakfast trays, Lucifer joins his mistress and takes great pleasure on hearing the punishments Lady Tremaine places on her stepdaughter. However, his pleasure turns to dismay when Lady Tremaine tells Cinderella to give him a bath, which suggests that he doesn't like baths or prefers to remain filthy.
