Steven Universe is an American animated television series created by Rebecca Sugar for Cartoon Network. It is the coming-of-age story of a young boy, Steven Universe (voiced by Zach Callison), who lives with the Crystal Gems—magical, humanoid aliens named Pearl (Deedee Magno Hall), Garnet (Estelle), and Amethyst (Michaela Dietz)—in the fictional town of Beach City. Steven, who is half-Gem, has adventures with his friends and helps the Gems protect the world from their own kind. Steven Universe premiered on November 4, 2013, and is Cartoon Network's first animated show solely created by a woman. The themes of the series include love, family, and the importance of healthy interpersonal relationships. Books, comics and video games based on the series have been released, and a film is in development.
