Applejack is a clumsy Earth pony. She joined the rescue team (including Megan, Firefly, Twilight, and Bow Tie) to go to Midnight Castle.

During the journey, she accidentally fell off a rigidity old bridge. Megan jump in to save her, and both were saved from drowning by the Sea Ponies.

She's the only main character other than Spike to be re-imagined in My Little Pony: Friendship is Magic. Only G4 Applejack is more athletic and her cutie mark is 3 apples rather than 5, like her G1 counterpart.

She is also the only main character to keep her own appearance throughout the Generations (except for Generation 3)
