Lucifer

Lucifer is the devilish pet cat of Lady Tremaine and a main antagonist from Walt Disney's 1950 hit Cinderella. He has black fur and is portrayed as a sneaky, devilish, and cheating mouse consumer. He is voiced by June Foray and currently Frank Welker.

Development
Lucifer was created for the sub-plot of the film for comedy. Lucifer was created to have cat and mice chase/comedy scenes which was done by Ward Kimball. Lucifer's design was from one of the cast members own cat.

Personality
Unlike many Disney villain henchman Lucifer is clever, cunning and not at all foolish, contrary to his mistress and her daughters. Lucifer is also clumsy and can be tricked, but can get back on track very quickly. Lucifer can also detect someone's presence. In the 3rd film, Cinderella was attempting to sneak by Lady Tremaine, Drizella, and Anastasia. She did without a problem, but once it came to Lucifer, she was almost exposed until Lady Tremaine demanded him to follow her. Lucifer also detected Jaq and Gus's presents as they attempting to sneak by Lucifer without waking him. Lucifer is also treated like a prince to Lady Tremaine. She cares for him deeply and acts as a mother figure to him. Lucifer may be loved by Lady Tremaine more than anyone else.

Design
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. Lucifer's sharp nails are usually always sticking out.

Cinderella
Lucifer first appears in Lady Tremaine's bedroom sleeping alongside her in a small prince-like cat bed. Cinderella takes Lucifer for his morning breakfast. Lucifer (believing it's too early) regretfully joins Cinderella. During his breakfast meal, Lucifer gets his rival Bruno, Cinderella's dog into trouble and joins in a comical chase with Jaq, Gus and the rest of the mice friends. Later in the film, whenever he hears Drizella's singing voice, he grabs the red pillow to cover his ears, moves out of the room and then closes the door with his back paw. While Cinderella is cleaning the floor, he makes a big mess with his paws, which really upsets her. When the two mice Jaq and Gus are able to take the sash and the bead necklace, Lucifer tries to catch them, but he misses. At the film's climax, he attempts to stop Jaq and Gus from freeing Cinderella from her locked room. Both the mice and bird battle Lucifer but he is too strong. Cinderella tells the birds to get Bruno to intervene. Bruno is able to do just that as he scares Lucifer so much, he falls out of the tower's window, but survives the fall, since cats always land on their feet.

Cinderella II: Dreams Come True
Lucifer later appears in the 2 sequels. In the 2nd movie, he only appears in the 3rd and final segment, An Uncommon Romance, where he falls in love with the snobby palace cat, Pom Pom, to the point that he makes a deal with the mice never to chase them again if they help him reconcile with Pom Pom. The plan works, Pom Pom goads Lucifer into helping her catch and eat the mice. His treachery backfires, and Pom Pom dumps him.

In the third film, after Lady Tremaine reverses time with the Fairy Godmother's wand, Lucifer resumes his role as adversary to both Cinderella and the mice. In his most notable scene, Lady Tremaine turns him into a human coachman to take Cinderella and the mice as far away from the palace as he can, but during the chase, Lucifer falls into the water, where he turns back into a cat and is stranded in the woods.

As Ventus takes it and creeps back for the mousehole, Lucifer wakes up and prepares to strike Ventus from behind, but Jaq warns Ventus at the last minute and throws balls of string at Lucifer to distract him, but Lucifer rams himself into the cabinet where Jaq was standing, causing Jaq to fall onto the floor. As Lucifer prepares to kill Jaq, Ventus intervenes and strikes Lucifer's paw. Angered, Lucifer engages Ventus in a battle, which Ventus wins. Lucifer subsequently runs off and isn't seen again.
