Applejack is an orange earth pony and one of the main characters in The FT Squad's Adventures in My Little Pony: Friendship is Magic. She's a very hard working pony who works as a farmer on Sweet Apple Acres in Ponyville with her grandmother Granny Smith, big brother Big McIntosh, little sister Apple Bloom and dog Winona. She's one of Twilight Sparkle's best friends. She's been known to be headstrong and insist on doing things by herself since she's very hard working. Despite this, she's kind and considerate. She represents the element of honesty in the elements of harmony. She's also one of Cassidy the Pelican's closest friends, since they both wear western style clothing and got along perfectly when they first met.
