My Little Pony Friendship is Magic

My Little Pony: Friendship is Magic is the 4th iteration of Hasbro's My Little Pony cartoon series and focuses on the adventures of the "Mane 6" protagonists and their adventures in learning about friendship.

The Mane 6 ponies each represent one facet of the "Elements of Harmony" which establish friendship. Furthermore, two of each kind represent each of the major pony species: earth pony, pegasus pony, and unicorn pony. The hard-working Applejack and the joyous prankster Pinkie Pie are the show's earth ponies and represent the harmonious elements of Honesty and Laughter, respectively. The tomboyish and sporty Rainbow Dash and the timid and animal-friendly Fluttershy represent the elements of Loyalty and Kindness. Lastly, the studious Twilight Sparkle and fashionable Rarity represent the elements of Magic (the rarest of all) and Generosity.

In the two part pilot episode, "Friendship is Magic," Twilight Sparkle has been studying in Canterlot for her mentor as well as the ruler of Equestria, Princess Celestia. Although Twilight is worried about a prophecy that the villainous Nightmare Moon will soon return to bring eternal night to the land, Celestia is more concerned with Twilight's lack of any friends; Twilight spends all her time studying and reading instead of socializing. Twilight is thus given the task of overseeing the preparations for an event in Ponyville, where Celestia will be raising the sun. It's during this time in Ponyville that the rest of the Mane 6 are introduced to Twilight as well as to the audience, culminating with Celestia absent and Nightmare Moon's return.

Twilight recalls her studies well and asks the other ponies to assist her in recovering the magical Elements of Harmony. They all agree, instantly acknowledging each other as friends. During their adventure into the ominous Everfree Forest, (where nature takes care of itself instead of needing ponies to help it out) each of the ponies proves their worthiness as an Element bearer in a final showdown with Nightmare Moon that awakens the Elements and allows Twilight to purify Nightmare Moon into Princess Luna as well as free Princess Celestia.
