Twilight Sparkle

Twilight Sparkle is depicted as an intelligent, studious, and sometimes socially awkward anthropomorphic unicorn (later an alicorn) with exceptional magical abilities. In the first season of the show, her mentor and royal patron, Princess Celestia, guides her to learn about friendship in the town of Ponyville, where she and her dragon assistant Spike become close friends with five other ponies: Applejack, Rarity, Fluttershy, Rainbow Dash, and Pinkie Pie. The six friends collectively are referred to as the Mane Six. Twilight represents the Element of Magic in the Elements of Harmony.
Created by Lauren Faust, Twilight is based on the unicorn toy Twilight from the first incarnation of My Little Pony toyline. The creative team also incorporated Twilight's personality into her design, such as her purple color and cutie mark. Twilight garnered praise for her relatability and complexity.
