"Rotten to the Core" opens the 2015 Descendants movie by introducing the Villain Kids—Mal, Evie, Jay, and Carlos—as they cause chaos on the Isle of the Lost and prove their evil, rebellious nature to the island's inhabitants. Following a high-energy musical number, Maleficent arrives and gives the VKs a mission to steal the Fairy Godmother's wand at Auradon Prep, setting the stage for the film's conflict between parental expectations and the kids' true selves.
