A transformation of Princess Luna, she is the little sister of Princess Celestia and a pony that was put to sleep for her trying to make night eternal years ago. Using the elements of harmony, Twilight Sparkle and the other main characters used their special element to defeat her and return day & night back to their normal balance. After she was back to her original state (Princess Luna), she was asked if she would rule aside her big sister to keep perfect balance between daylight and nighttime.
