Lady Tremaine (also commonly known as the "Wicked Stepmother") is a fictional character and the main antagonist of Disney's 1950 animated feature film, Cinderella. As the coldhearted stepmother of the title character, Lady Tremaine doesn't harm her stepdaughter physically. Rather, she seeks to punish and abuse her psychologically, motivated by her jealousy of Cinderella being far more beautiful and graceful than her own awkward daughters, Anastasia and Drizella.
Lady Tremaine was also a socialite, determined to gain higher status by having one of her daughters married to Prince Charming or another bachelor of noble blood and status. After being defeated once for all, Lady Tremaine and her oldest daughter were deprived of their high social statuses as socialites by instead becoming scullery maids and forced to work at the King's Castle for all of their actions against the kingdom.
