Created by Lauren Faust, My Little Pony: Friendship Is Magic began in October 2010 and ran for nine seasons (222 episodes) until October 2019. It was based on My Little Pony by Bonnie Zacherle. It takes place in the land of Equestria where a wide variety of ponies, Pegasus and unicorns live alongside a wide range of sentient and non-sentient creatures.
Throughout the show we follow Twilight Sparkle (voiced by Tara Strong), a unicorn mare sent by her mentor Princess Celestia (voiced by Nicole Oliver), ruler of Equestria, to the town of Ponyville to study the magic of friendship. Initially Twilight resents this assignment, as she is more concerned about the foretold appearance of Nightmare Moon (voiced by Tabitha St. Germain), the evil sister of Celestia.
When Nightmare Moon does appear, vowing everlasting night and causing Celestia to disappear, Twilight sets off with five other ponies – Applejack (voiced by Ashleigh Ball), Fluttershy (voiced by Andrea Libman), Pinkie Pie (also voiced by Libman), Rainbow Dash (also voiced by Ball), and Rarity (also voiced by (Tabitha St. Germain) – to obtain the Elements of Harmony and defeat Nightmare Moon.
Later Nightmare Moon destroys the elements and all appears to be doomed when Twilight has an epiphany that each of her new friends represents one of the Elements of Harmony (Honesty, Loyalty, Laughter, Generosity, and Kindness), and that she herself is the final piece, Magic. The magical power of the ponies’ friendship reverts Nightmare Moon to a repentant Princess Luna. Celestia reappears, reunites with her sister Princess Luna, and decrees that Twilight shall stay in Ponyville to continue studying the magic of friendship, much to the happiness of Twilight and her new friends.
