King Sombra

King Sombra is a male unicorn and the main antagonist in the third season's premiere The Crystal Empire. Princess Celestia tells Twilight Sparkle that he took over the Crystal Empire a thousand years ago, but was banished into the frozen north. Sombra put a curse on the Crystal Empire which made it vanish into thin air. When the Empire returns, so does King Sombra, who attempts to retake it. He is defeated by the Crystal Ponies' use of the Crystal Heart. His dialogue consists of growls, snarling, hissing, menacing laughter, and five lines.
