1. Maleficient : the main villain of Walt Disney's 1959 film Sleeping Beauty. She is characterized as the "Mistress of All Evil" who, after not being invited to a christening, curses the infant Princess Aurora to "prick her finger on the spindle of a spinning wheel and die" before the sun sets on Aurora's sixteenth birthday. She was voiced by Eleanor Audley, who earlier voiced Lady Tremaine, Cinderella's evil stepmother, in Cinderella (1950). Maleficent was created by Marc Davis and is based on the evil fairy godmother from the original fairy tale of the same name by Charles Perrault and The Brothers Grimm.

A more sympathetic version of the character appeared as the protagonist in the 2014 live-action film Maleficent, portrayed by Angelina Jolie. She also serves as a minor antagonist in Disney's House of Mouse, voiced by Lois Nettleton, and as a recurring antagonist in the Kingdom Hearts video game series, voiced by Susanne Blakeslee. She is also one of several antagonists in the TV series Once Upon a Time, portrayed by Kristin Bauer van Straten, and the Disney Channel movie Descendants, portrayed by Kristin Chenoweth.

2. Dystopia : a community or society that is undesirable or frightening. It is translated as "not-good place", an antonym of utopia, a term that was coined by Sir Thomas More and figures as the title of his most well-known work, Utopia (the blueprint for an ideal society with minimal crime, violence and poverty). Dystopian societies appear in many artistic works, particularly in stories set in the future. Some of the most famous examples are George Orwell's 1984 and Aldous Huxley's Brave New World. Dystopias are often characterized by dehumanization, totalitarian governments, environmental disaster, or other characteristics associated with a cataclysmic decline in society. Dystopian societies appear in many subgenres of fiction and are often used to draw attention to real-world issues regarding society, environment, politics, economics, religion, psychology, ethics, science, and/or technology. Some authors however also use the term to refer to actually-existing societies, many of which are or have been totalitarian polities, or societies in an advanced state of collapse and disintegration. An attempt to draw together and compare both the fictional and real dystopias has been made in Gregory Claeys's Dystopia: A Natural History (Oxford University Press, 2016).
