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 reimagined 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)
