"Mary Sue is a unicorn who dreams of becoming an alicorn princess. She's gentle, ambitious and determined to make her dream come true yet egocentric and will do anything to achieve her goal, thus making her naive. She obviously looks up to the royal ponies but feels envy towards Twilight Sparkle. She considers herself a born leader although there's so much more that she has to learn about teamwork."
