She's a tall Alicorn with a pure black coat and a flowing night-sky-like mane, teal dragon-like eyes and light blue Starmetal Armor. Her cutie mark is a huge blot with a white crescent moon. She's egotistical, sneaky and manipulative, not to mention cunning. She's bitter towards Princess Celestia for banishing her for 1,000 years, and she's banished her to the moon as punishment. She's the sole ruler of Equestria at the moment and will be for the forseeable future, keeping the world in night.
