This is Night Shade, she used to be good but then something made her turn Evil. That was after she got her Cutie Mark. If you look closely you can see scratch marks over her CM, thats because when she turned evil something scratched it. The other scratches/scars are from battles and encounters with beasts or very dark creatures like Timber Wolves and other beats with sharp claws/teeth. Her collar is dog teeth & her necklace has a baby dragon tooth. Usualy she has Armor covering her face, back, chest, Cutie Mark, Legs, & Wings. The reason she covers her CM up is she has two sisters who are good {My Ponysonas Zephyrine & Zahra}. Her sisters know they had an older sister but they never knew that their older sister was Night Shade and how evil she had become, they may find out but who knows. Night Shade leads a large group of evil ponies and creatures outside of Artistry waiting for the best moment to strike.
